Section 4: Ship's and Scientific Equipment Description
ACOUSTIC DOPPLER CURRENT PROFILER (ADCP) - Roger Revelle has a 75kHz and 150kHz RDI Ocean Surveyors installed that are capable of either narrowband, broadband, or interleaved operation. These provide vertical profiles of ocean current speed and direction. The system utilizes the doppler effect to measure currents in the water column. Current profiles can be produced in as many as 128 depth cells, each cell being variable from 1 to 32 meters to a maximum depth of 700 meters. When the bottom is within range, an earth-referenced vessel velocity can be obtained which allows for the measurement of absolute currents. Data are processed and current profiles are displayed in real-time on a color monitor. Data processing and recording are done on a Linux (Ubuntu) system using UHDAS software. The system takes inputs from the ship's motion reference systems and GPSes. Heading corrections are derived from the ship’s motion reference systems and the Trimble ABXTWO differential GPS array -- these corrections are applied to the data in real-time.
A-FRAME - The A-frame is located at the stern. It is rated above the breaking strength of 9/16" wire (32,500 lbs) in its braced position and has a safe working load of 21,667 lbs when in motion (hydraulically driven). It is one of two means (the other is the starboard quarter crane) to lead trawl wire or 0.680" EM wire overboard and is the only route for fiber optic cable.
AIR, COMPRESSED - (See COMPRESSED AIR in this section.)
AIR CONDITIONING AND HEATING - The ship's air conditioning system is extensive and complex, with zone-by-zone and even room-by-room control. If the ventilation or air conditioning in your room or working space seems not to be operating correctly or not to be controlled properly by the pertinent thermostat, please ask the engineer on watch for help. Do not resort to system-defeating measures like blocking vents, etc.
BOATS - A 23-ft Hurricane semi-rigid inflatable boat (SRIB) is normally carried by Roger Revelle as a work boat. Specific requests should be made to the marine superintendent prior to departure of the ship from San Diego to ensure that a boat meeting your requirements is available. At sea the crew controls launching, operation and recovery of boats.
BOATSWAIN LOCKER - The primary boatswain's locker for rigging and deck supplies used by the crew is located at the extreme forward end of the main deck. Auxiliary lockers are located at other places on the weather decks. They also contain rigging/securing items, such as cleats and eyebolts, for use with the 2' deck bolt-down pattern. The resident technician or a crew member will assist you in their use if necessary.
BULWARKS - Bulwarks on the main deck aft are capable of being removed in sections, to permit loading and handling of large and/or heavy objects. Requirements for the removal of bulwark sections should be discussed in advance with the marine superintendent or the captain. Bulwarks are personnel safety devices their removal is not treated lightly. They are not normally removed or installed at sea.
CABLE RACEWAYS - Raceways and cable pass-throughs run between labs, from labs to bow, from the labs to the fantail and staging bay, and up to the pilot house and mast. The unistrut network throughout the labs affords additional ways to route and secure scientific cables. Consequently, it should almost never be necessary to route scientific cables in the overheads, and use of the overheads for this purpose is discouraged. If you do not see immediately how to route your cable outside the overheads where you want it to go, consult any STS technician. Do not disturb existing wiring and remember to remove yours at the end of your cruise.
CAPSTANS - There is normally a large capstan on the fantail. (See MAIN DECK in Section 3.)
CHEMICALS - Use care in storage, handling, and disposal of toxic chemicals, particularly inside laboratories. All chemicals brought on board should be accompanied by a Material Safety Data Sheet (MSDS) provided by the chemical manufacturer. Plastic bottles are safer at sea and should be used unless specific chemicals must be stored in glass. Disposal of chemicals is regulated by University policy and international laws. The ship's captain must know what chemicals you are carrying. A chemical storage locker is available and is the only safe way to carry most chemicals aboard ship. Please make arrangements with the research technicians in advance for proper stowage and for appropriate disposal at the end of your cruise.
Working supplies of hazardous chemicals may be kept beneath fume hoods. Stocks/reserve supplies are to be kept in the appropriate storage.
CLEAN POWER - (See ELECTRICAL SYSTEM in this section.)
COMPUTER SYSTEMS, ACQUISITION, IT, PRINTERS - Shipboard computer systems are run on a redundant cluster for high availability of scientific systems. All scientific systems are run as virtual machines which are distributed via the ship’s network and displayed/controlled via a multicast KVM system.
The various Windows, Linux, and Mac acquisition machines perform a standard set of data acquisition, archiving and processing functions on many of the permanently installed data collection systems. All data is archived in regular intervals to our shipboard file server. All systems in the electronics/computer lab are powered through a data center grade UPS. Some of the permanently installed data acquisition systems include (see also separate entries for these items):
- 75kHz and 150kHz RDI Ocean Surveyors ADCP, running University of Hawaii's UHDAS software.
- UCSD Ocean Physics Group 50 and 140 kHz High-resolution Hydrographic Doppler Sonar System (HDSS), using OPG's HDSS software.
- Turo Quoll XBT system, used with Sippican Fast Deep probes
- Kongsberg EM124 bathymetric mapping system
- Kongsberg EM712 bathymetric mapping system
- Knudsen Engineering 3260 and 320B/R 3.5 & 12 kHz singlebeam echosounder sub-bottom survey system
- Simrad EK80 Fisheries Sonar – (18 kHz, 38 kHz, 70 kHz, 120 kHz, 200 kHz)
- Seapath 330+, and Phins-III are the main MRU's for our acquisition systems.
- Kongsberg Seapath 330+, Trimble ABXTWO, and Furuno GP-170 GPS systems provide time, position, heading, and attitude information at various frequencies for the science equipment. Feeds from these instruments can be accessed through the science repeater boxes in the labs, and through the SIS boxes throughout the vessel.
- Seapath 330+, Trimble GPS and End Run time servers that provides NTP GPS-derived time, and 1 PPS synchronization along with other time measurements
- MET meteorological system that provides wind speed/direction, relative humidity, barometric pressure, long and shortwave radiation, air temperature, sea surface temperature, and precipitation.
Scanners, copy machines, printers, and a large-format plotter are available to use. There is Wi-Fi access in the public areas of the ship where anyone can connect to view the ship's intranet. Cruise data will be accessible and updated at regular intervals from a central NAS server, from any computer aboard. Serial feeds (DB9) or UDP feeds of navigation, MET, and MRU data are available in all labs, and can be configured by the shipboard technicians.
The shipboard instrumentation technician operates and maintains the oceanographic instrumentation and data acquisition equipment. They will be able to assist in ship account creation, general IT services, science equipment repair, interfacing with the acquisition machine and data downloading. At the end of a cruise, the instrumentation technician will provide the entire cruise data set that was collected from all shipboard systems to the chief scientist.
It is recommended that necessary printer drivers are loaded on all computers being brought aboard ahead of time -- trying to download the large files over the Internet during the cruise will not be possible:
- HP Pagewide Pro 577 (main lab)
- HP Color LaserJet M751 (electronics/computer lab)
- HP DesignJet T1600 (main lab) -- this is a large-format plotter
COMPRESSED AIR - Ship's service air is 100 psi at 12 cfm. The upper limit cannot be used continuously. It is suitable for running pneumatic tools but may not be dry or clean enough for laboratory use. Users should plan to supply their own filters if the air is intended for any lab use. There are numerous outlets in the labs.
Two large North Pacific cranes are permanently mounted on the ship, one on the port side 02 level and one on the main deck starboard quarter. These cranes have a dynamic range capability of 10 to 65 ft and a dynamic load capability of 21,000 to 1,700 lbs. These dynamic load conditions are good up to sea state 5. In port, at sea state 0, these cranes can lift 42,000 to 3,400 lbs. with a 10 to 65 ft reach. These cranes can only be operated by qualified crew members or the research technician.
The ship carries a Morgan Marine 18,000 portable deck crane. Crane capacity is 14,000 lbs at 6 ft to 3,000 lbs at 46 ft. Crane winch is rated at 4,000 lbs pulling strength. The crane base is designed to interface with the working deck bolt-down system to provide flexibility. The crane serves the forward scientific storeroom via a hatch that opens in the foredeck when carried on the forward 02 deck. The hatch may not be opened at sea. The crane can also be located on the main deck as needed. This crane is operated by the resident technician or qualified crew members only.
DMG 12000ET2 extension crane is carried stbd side 01 level aft of the rescue boat. This crane services the stbd side midships. Boom 2'to 27' capacity 0-2900 lbs. Operated by ship’s crew and restech.
CUSTOMS - Shipping equipment to and from foreign ports requires long lead times and planning. Science parties are responsible for getting their equipment alongside the vessel in port in time for their schedule mobilization, and picked up from port during their scheduled demobilization.
DECK LOADING - In addition to the main deck, equipment may be loaded on the 02 level forward, the 01 level aft on the port side, and (limited) on the foredeck. The approximate loading limit is 0.5 ton/sq ft.
Ship stability is ultimately the responsibility of the captain. The responsibility of scientists is to consult the Nimitz Marine Facility or the researcy technician early to describe loading plans and requirements so that any necessary adjustments can be made. The more complex and heavier your equipment the more advance notice is needed. Our goal is to resolve loading problems and incompatibilities well before sailing day, so that it will not be necessary to leave scientific gear on the dock to assure a safe ship.
DECK TIE-DOWNS - No welding is permitted directly to any deck. All installations must use the 2 ft x 2 ft grid of tie-downs (welding may be done to “ears” or plates, which in turn are bolted to the deck). Bolt holes are 1" NC thread on weather decks, 1/2" NC thread in labs and storerooms. Bolt holes in equipment should be made oversize, to allow for deck grid irregularities.
DEPTH RECORDING - (See ECHOSOUNDING in this section.)
DISTILLED WATER - (See FRESH WATER in this section.)
DOPPLER LOG - An Furuno doppler speed log is installed in the chart room for ship speed measurements; its output is available on a repeater in the lab. (Also see ACOUSTIC DOPPLER CURRENT PROFILER in this section.)
DRAINS - (See also CHEMICALS in this section.) All lab sinks drain directly overboard, or into the sewage holding tanks. Ship's engineers control the drain routing and should be consulted about specific drainage requirements.
The under-sink areas in the lab should (1) be carefully inspected before using the sinks to ensure that connections are in fact connected and open, (2) be kept clear of stored items capable of damaging PVC pipes or blocking drains, and (3) be kept clear of lab trash and debris.
ECHOSOUNDING - There is a 16-element array of transducers which operate at 3.5 kHz, and two MASSA 12 kHz transducers which are operated individually. These can be accessible by portable deck units behind the forward server racks in the electronics/computer lab. These are normally used by the Knudsen 3260 deck unit for sub-bottom profiling and/or singlebeam depth sounding. The data is digitized and may be stored in SEG-Y format. Data is graphically displayed on the display array.
There is also a Kongsberg EM124 12 kHz multibeam for bathymetry data. The main power and transceiver units are in the Transceiver room, two decks down from the main deck.
ELECTRICAL SYSTEM - The permanently installed lab power systems include 120-, 208-, and 240-volt receptacles. 120-volt vital systems utilize the 15 kVA uninterrupted power source. The UPS provides 15 minutes of power at its rated load should a power failure occur. The ship has the following power plant elements:
- 2 ship service diesel generators (SSDG), 690VAC @ 2,100 kW
- 2 ship service diesel generators (SSDG), 690VAC @ 940 kW
- 2 1,500 kVA transformers 600vac to 480vac
- 2 150 kW m.g. sets for clean power, providing 90 kVA of 120VAC power to the various labs on the main deck
- 10 kVA @ 240VAC single phase clean power in labs
- 9 kVA@ 220VAC single phase clean power in labs
- 3 100 amp 480VAC deck receptacles, two at the aft end of the staging bay, one at the bow, 01 deck
- 1 30 amp 480VAC deck receptacle in the staging bay
- 2 30 amp 480VAC deck receptacles on weather deck aft end of staging bay
- 4 30 amp 208VAC deck receptacles and 4-30 amp 120vac 3-phase clean power deck receptacles, two of each kind aft of the hydro lab for main deck vans, and aft on the 02 deck for 01-level vans
ELECTRO-OPTICAL TOW CABLES - See the cable specifications.
INTERNET - (See also COMPUTER SYSTEMS, and SATELLITE COMMUNICATIONS) Internet access is available to all users but can be slower than typical land based, broadband systems.
FLOOD LIGHTS - Working lights on deck are controlled by the bridge. Consider the night vision of the crew and use only the lights you need, turning them off when finished.
FREEZER - (See REFRIGERATION AND FREEZING in this section.)
FRESH WATER - Fresh water generation capacity is about 4,000 gals/day. The ship also has 2 evaporation distillers which put out very pure water that can be used to fill carboys. Potable water tank capacity is about 12,000 gals. A MilliPore Milli-Q IQ7000 Water Purification System is located in the Hydro Lab and a MilliPore Milli-Q Advantage A-10 Water Purification System is installed in the Analytical Lab to provide pure water for science use.
Fresh water should not be used for wash down purposes, except if necessary and then by consultation with the resident technicians. In personal use, conserve. Take short showers; do only full laundry loads. (See Section 8: SHIP ORGANIZATION.)
GASES - (See STORAGE in this section.) These are the responsibility of the individual requiring gases for shipboard use. Any gas under pressure is dangerous; consult the captain or the resident technician for safe stowage methods and locations.
GASOLINE - Inspected vessels are severely limited by law in the amount of gasoline they can carry, unless they have approved built-in tanks, which R/V Roger Revelle does not. Small amounts of gasoline for outboard motor use at sea are carried in USCG-approved containers.
GENERATORS - (See ELECTRICAL SYSTEM in this section.)
GYRO – Kongsberg Seapath 330+, and a Phins Gen. III are the two main MRU's used for the various scientific sensors aboard the vessel. The ship's gyro has a repeater in the electronics/computer lab. MRU and gyro data are available in the lab.
HATCHES - Hatches and watertight doors are heavy and dangerous if not secured correctly. Careful use of all doors and hatches, especially at sea, is very important. Carelessness could easily lead to severe injury. All doors and hatches should be positively latched either open or closed at all times, never left to swing free.
HIGH-RESOLUTION HYDROGRAPHIC DOPPLER SONAR SYSTEM (HDSS) - The High-resolution Hydrographic Doppler Sonar System, developed by UCSD's Ocean Physics Group, have two sets of sonars installed on the R/V Roger Revelle. One set is a 50 kHz unit and the second set is 140 kHz, each consisting of 4 beams. The sonars measure ocean velocities and shears with very high precision.
HOLD - (See description of forward and lower scientific storerooms under LABORATORY SPACES in this section.)
HOODS - There are four fume hoods, one each in the analytical lab, the hydro lab, the main lab and the wet lab.
HYDRAULIC SYSTEM - (See also A-FRAME, CRANES, and HYDROBOOM in this section.) The A-frame and hydroboom are hydraulically operated, as are all cranes. Operating controls for the frame are located on the starboard side of the frame. The hydroboom control is located in the hydro winch control booth.
Questions regarding user applications of excess hydraulic capacity should be directed to Nimitz Marine Facility (the marine superintendent, the port engineer, or the chief engineer of Roger Revelle) well in advance.
HYDROBOOM - The hydroboom located on the 02 level starboard side is a McElroy model 15000. The hydroboom is used for launching and recovering oceanographic equipment and fairleading wire from the DESH-5 hydrographic winch. It is designed for a safe working load of 15,000 lbs perpendicular to the ship's deck. The total length of the hydroboom fully extended is 43 ft. The extension boom is 18 ft long and reaches over the starboard side by 10 ft when fully extended. The distance from the bottom of the sheave, on the end of the boom, to the deck is 20 ft. The hydraulic control for the boom is located in the forward Winch Control Station. This boom is operated by the winch operator.
HYDROWINCH - (See WINCHES in this section.)
INSTRUMENT WELL – Located in the Main Deck Hangar, a 23” diameter well is available for installation of a variety of instruments. The ship carries a “Pipe String” designed for full ship speed deployment of instrumentation in the instrument well. A Portable HIPAP USBL system is available for use on the Pipe String. Any planned use of the instrument well, pipe string, or HIPAP should be coordinated with the Research Technician Group well in advance of a cruise.
ISOTOPES - (See RADIOACTIVE MATERIAL in this section.)
INTERCOM - (See INTERNAL COMMUNICATIONS, Section 6.)
LABORATORY SPACES - Please refer to the deck plans for dimensions and layout of the laboratories and other science spaces. Virtually all scientific spaces are on the main deck. The approximate sizes of the labs and other science spaces are as follows. These are the areas that are clear and unencumbered by such uses as passageways through the space, ship equipment, etc. They therefore may not correspond to areas of the spaces shown on general arrangement drawings.
All labs and storerooms are fitted with the standard 2' x 2' 1/2" NC bolt-down pattern on deck, accepting bolts which are 1/2" deep. Unistrut mounting channels are on the bulkheads and overheads. An inventory of Unistrut hardware and fasteners is maintained on board by the research technician.
In sequence from bow to stern and main deck to 1st platform, these spaces are:
- Forward science storeroom 358 sq. ft.
This storeroom is at the forward end of the main deck passageway. It is served by a hatch that opens on the 01 deck forward. A network of deck tiedowns and Unistrut fixtures permits flexible securing arrangements. Standard pallet-sized loads can be craned into this storeroom through the hatch. All labs served via pallet jack down passageway.
- Cardio Gym 76 sq. ft.
An assortment of cardio gym equipment is available for science and crew use.
- Ship’s Office 65 sq. ft.
This space is used by the ship’s crew for general ship diagrams and supplies.
- Main Lab 1,745 sq. ft.
This is largely flexible general lab space, with extensive utility connections and Unistrut capability, configurable to suit the onboard project(s). It has a fume hood, small -80 freezer, and a convertible chest freezer/refrigerator.
- Analytical/Biochemical Lab 330 sq. ft.
This lab has its own air conditioning and ventilation system, for fine control of ambient conditions needed by some analytical work. There is a fume hood and a refrigerator.
- Climate control chamber (1) 63 sq. ft.
A walk-in chamber; the temperature may be controlled from 4 to 40 C, with sensitivity of 0.1 C and uniformity within the chamber of 0.5 C.
- Climate control chamber (2) 63 sq. ft.
A walk-in chamber; the temperature may be controlled from 4 to 40 C, with sensitivity of 0.1 C and uniformity within the chamber of 0.5 C.
- Computer Lab/Data Center 610 sq. ft.
This location is divided between the Data Center, which houses the ship’s main servers and compute infrastructure, and the Computer Lab where the ship’s main display array is located for viewing and controlling the ship’s oceanographic instrumentation. There is desk space available for science watch standers as well. The primary work site for the Shipboard Instrumentation Technician and Research Technician is here, as are the hubs of the data and video networks and science information system. The lab has a secondary control station for lab control of winches.
- Hydro Lab 693 sq. ft.
Has access aft to two vans, plus general lab outfitting. Van access can be fully enclosed if van door arrangements are suitable.
- Wet Lab 230 sq. ft.
With direct access to the staging bay aft, this lab is the site for wet work, wet sample preservation, etc. The lab has a fume hood.
- Staging bay 330 sq. ft.
A sheltered workspace. Clearance from overhead to deck is 18 ft. It has a telephone and outlets for compressed air and electricity. Roll down doors, starboard and aft, offer limited protection against weather. Padeye lifting points in the overhead exist. Overhead hoists are installed; 5,000 lb capacity each.
- Aft science storeroom 635 sq. ft.
This is the other major science storeroom, forward of the winch room on the 1st platform. Some of this space (port side) is used for ship's engineering spares storage. A pallet-sized hatch to the storeroom opens to the main deck just outboard of the starboard rollup door of the staging bay.
A suite of scientific meteorological sensors (see MET in this section) is on the bow of the ship, on a science mast.
MET - The Shipboard Meteorological Acquisition System (MetAcq) acquires, filters, averages, corrects, displays, and distributes meteorological sensor data from a wide variety of sensor types and data input devices.
Meteorological sensors such as ones made by RM Young, Vaisala, Alden, Coastal Environmental Systems, Seabird, FSI, Omega and most sensors that have an RS485, RS422, RS232 digital interface or any analog sensor that can output a voltage, frequency or 4-20ma current can be accommodated.
A typical system measures air temperature, barometric pressure, wind speed/direction, relative humidity, shortwave radiation, longwave radiation, seawater temperature, and seawater conductivity. Sensor information is combined with time and GPS position information and displayed on the local video display or web server and written to data files. Acquired data that has been collected from the sensors (uncalibrated) is stored in an uncorrected data file. Data that has been corrected by applying the most recent pre-cruise calibration data is stored in a corrected data file.
Atmospheric meteorological sensors are generally located on either the forward part of the ship on the MET mast and/or above the ship's upper bridge deck. Sensors that measure seawater properties are generally located near the uncontaminated seawater intake area or in one of the ship's laboratories that has a connection to the uncontaminated seawater line.
At least once a year all sensors are removed from the vessel, refurbished, and calibrated at an appropriate shore-based maintenance/calibration facility. Calibration data for each sensor is kept onboard each vessel and entered into the shipboard acquisition/setup file that is used by the acquisition program to correct sensor data for display and storage.
- Kongsberg EM124 12 kHz Multibeam Echosounder mapping system for deep water bathymetery.
- Beams map 6-7 times the water depth (25 km swaths in deep water)
- Kongsberg EM712 40 – 100 kHz Multibeam Echosounder mapping system for shallow to midwater bathymetery.
- Turo Devil Expendable Bathythermograph System (XBT) (one probe per day for calibrating Multibeam systems if additional probes are required advanced planning and additional funding is necessary.
- Software: Kongsberg SIS acquisition system.
PROPULSION - Roger Revelle is equipped with twin "Z" drive propellers aft, trainable 360 degrees. Propeller speed is variable from 0 rpm to full. A White-Gill azimuthing water-pump bow thruster is used for precision maneuvering, dynamic positioning, station-keeping, etc. Thrusters can be controlled independently or integrated through a Kongsberg dynamic positioning/maneuvering system. Dynamic positioning is driven by inputs from GPS. Roger Revelle is capable of accurate station holding, positioning and track line following in most wind and sea conditions. For fuller details of handling and maneuvering characteristics, consult the captain.
RADIOACTIVE MATERIAL - The use of radioisotopes, or other isotopes in concentrations not found in nature, is strictly controlled aboard Roger Revelle. Permission to use radioisotopes must be obtained from the SIO Radioisotope Use Committee in writing, following written application (which is reviewed by the Radioisotope Committee) describing aims of the work and the isotopes, quantities, and procedures to be employed. Such usage must be consistent with strict precautions for safety and to prevent contamination of the ship. All handling of isotopes must be done within a designated portable isolation van. Vans are available upon request from the UNOLS Van Pool (the Research Technician group can assist with these requests). Cleanup costs of any isotope spills will be charged to the persons responsible.
REFRIGERATION AND FREEZING - (See also "Science Freezer" and "Climate Control Chamber" under LABORATORY SPACES in this section.) Revelle has several lab refrigerators and freezers available, please consult the Research Technician Group early on in cruise planning with specific cold storage requirements.
SCIENCE INFORMATION SYSTEM (SIS) – There is a system of twisted pair copper wiring to support the distribution of data from/to the Data Center and laboratories and other key locations around the ship.
SCUBA DIVING - All diving from SIO vessels is controlled by the diving officer. Please contact the Research Technician group early in your cruise planning process if your research requires SCUBA diving support.
There is no decompression chamber on R/V Roger Revelle.
SEAWATER - There are multiple bibs for seawater wash down on the weather decks. Checking with the deck watch officer is appropriate before hooking up and using any hoses. Sea water for incubation purposes is available. For quantity, flow rate, etc., check with the engineer.
SHEAVES & BLOCKS - Use of various winches and wires implies use of certain combinations of sheaves and blocks. In addition, your scientific operation may have requirements for fair-leading wires to certain locations. Be sure to check with the Research technician well in advance to explain all your wire rigging ideas and needs. Technicians will know how to best accomplish your task. Never use a sheave that is too small in diameter for the wire.
SHIPPING - Limited stowage on board R/V Roger Revelle often necessitates shipping equipment and samples. Shipments can be made to the ship's agent in ports other than San Diego; contact the Nimitz Marine Facility for the agent's addresses. Agents charge for every service they provide; science users should arrange in advance to cover any costs associated with shipping or receiving their equipment or samples. Please include the Port Captain, Ship’s Captain, and Research Captain in any dealings with the ship’s agent. (See also CUSTOMS in this section.)
STORAGE - (See entries under LABORATORY SPACES in this section for forward and lower scientific storerooms, GASES for storage of gas cylinders, and CHEMICALS for storage and use of lab chemicals and hazardous materials.)
SUPPLIES AND EQUIPMENT -
While not possible to stock everything anyone might conceivably wish to have at sea, the ship maintains an inventory of tools and supplies to supplement needs where possible. The ship does not carry a standard suite of analytical or special-use equipment. (See also Section 5.)
UNCONTAMINATED SEAWATER - Uncontaminated seawater is provided via a pump in the bow thruster room at 50 gal/minute, and from a pump from the engine room and or a pump forward near the bow thruster, the pumps are connected to the hydro lab. Distribution to various labs via plastic piping. Please check with duty engineer for hookups of supply and drainage.
VANS - Roger Revelle can carry multiple laboratory, refrigeration, and storage vans. Two vans can be sited aft of the hydro lab and can have enclosed access to that lab if the van door arrangements are suitable. Two more van sites are on the 01 level, port side. The 02 deck forward of the house has space for 4 full vans. (Decks have special cam-loc fittings in these locations.) Other deck space is available for vans as necessary.
Plans to use any vans should be indicated on the Marine Facilities Planning tool and details should be discussed with the research technician well in advance of departure.
WINCHES - The Markey DUTW-9-11 traction winch is in the winch room on the 1st platform level. Two stowage drums can carry up to 15,000 m of 9/16" wire on one drum and either 10,000 m of 0.680" electromechanical wire or 10,000 m of fiber optic cable. The unit is driven by a 150 hp electro-hydraulic power pack. Wire is led over the side through the A-frame aft or through the trawl crane on the starboard side aft. Fiber optic cable can also be used, led to the stern A-frame. Trawl crane may require use of boom crutch. Check with research technicians.
The primary Hydro winch is a Markey DESH 5 (75 hp AC-SCR/DC drive). It is located on the 02-level aft of the house, and holds up to 10,000 meters of 0.322" conducting wire or 0.250" mechanical wire. Wires can be led over the side via the hydroboom boom. This winch can be configured for either CTD or hydroboom operations.
The primary CTD winch is a Markey CAST 6 (75 hp AC-SCR/DC drive) integrated with an Allied articulating load-handling system. The winch holds up to 10,000 meters of 0.322" conducting wire, which can be led overboard using either the Allied load handling boom or the hydroboom.
WIND & SPEED DIRECTION INDICATORS - (See MASTS in this section.)
WIRE - A log is maintained by the chief engineer documenting the actual wire on each winch at any given time. The working end of every wire is occasionally cut off and the termination replaced, and this can sometimes amount to 100 meters or more if damage has been sustained by the wire.
It is important that expected water depths of planned operations be made known to the research technicians and the marine superintendent as far in advance of these operations as possible, to ensure that adequate wire is available. Lead times on the purchase of new wires can amount to a year.
XBT - A Turo Quoll XBT system used with Sippican Fast Deep probes is permanently installed. It is available for general use, but stocks of XBT probes beyond the one per day budgeted for calibration of the multibeam system must be user-supplied.
