Section 4: Ship's and Scientific Equipment Description

A-FRAME - The A-frame is located at the stern. It has a safe working load of 30,000 lbs when in motion (hydraulically driven). It is the only means 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 19-ft Workskiff aluminum boat is normally carried by Sally Ride as a work boat. Specific requests should be made to the marine superintendent prior to departure of the ship from San Diego to insure that a boat meeting your requirements is available. At sea the crew controls launching, operation and recovery of boat using the main ship’s crane.

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 focsle 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. As a consequence, 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 resident 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 - (See Information Systems and Data Acquisition in this section.)

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.

CRANES - Permission to operate cranes is strictly limited to authorized personnel. These cranes are operated at sea only by permission of the captain.

Main crane, Allied TK70-70 on 01 deck. Telescoping knuckleboom, 10,000 lbs at 70 feet extension (sea state 4), 22,000 lbs at 70 feet (sheltered ops). Portable crane, Allied TK4-30 telescoping knuckleboom, 2,000 lbs at 30 feet extension. Normally carried on 01 deck forward, other locations possible to suit mission. 

DECK LOADING - Ship stability is ultimately the responsibility of the captain. The responsibility of scientists is to consult the Nimitz Marine Facility or the resident technician early to describe loading plans and requirements so that any necessary adjustments can be made. The more complex and heavy 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 in order 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 main deck, 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 SONAR in this section.)

DISTILLED WATER - (See FRESH WATER in this section.)

DOPPLER LOG - (See SONAR in this section.)

DRAINS - (See also CHEMICALS in this section.) Main lab sinks drain directly overboard, or into the sewage holding tanks. Ship's engineers control the drain routing and should be consulted in advance.

The under-sink areas in the lab should (1) be carefully inspected before using the sinks to insure 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 - (See SONAR in this section.)

ELECTRICAL SYSTEM - The permanently-installed lab power systems include 120, 208, and 240 volt receptacles. The ship has the following power plant elements:

  • 4 Cummins diesel generators, 690VAC @ 998 kW for propulsion and or ship service power

  • 2 each 1,500 kVA transformers 690vac to 480vac

  • 120VAC 20A receptacles throughout Main and Wet Labs.  Each Lab fed by 45kVA transformer.

  • 2 each 240VAC 3 phase 50amp receptacles in Main and Wet labs.

  • 2 each 208VAC 3 phase 50amp receptacles in Main and Wet labs.

  • 1 240VAC and 1 208VAC 3 phase 50 amp receptacles in Computer lab.  

  • 1 each 400 amp 480VAC 3 phase connection in the Staging bay

  • 3 each 100 amp 480VAC 3 phase deck receptacles, 1 Portside fantail, 1 in the Staging bay, 1 Stbd side working deck.

  • 10 each 60 amp 480VAC 3 phase deck receptacles, 1 01 deck fwd. Stbd, 1 port fantail, 2 Stbd fantail, 1 working deck port, 3 in staging bay, 1 working deck stbd. and 1 Stbd quarter dk.

  • 3 each 20 amp 480VAC 3 phase deck receptacles, 1 Foc’sle deck aft, 2 main deck aft.

  • 9 each 60 amp 240VAC 3 phase deck receptacles, 1 Foc’sle Dk Aft, 1 Port fantail, 1 Stbd fantail, 2 in staging bay, 2 Stbd working deck, 2 portside main deck aft midship

  • 3 each 60 amp 208VAC single phase deck receptacles, 1 Foc’sle deck aft, 2 portside main deck aft midship.

  • 3 each 60 amp 120VAC single phase deck receptacles, 1 Foc’sle deck aft, 2 portside main deck aft midship.

EMAIL/INTERNET - (See also INFORMATION SYSTEMS AND DATA ACQUISITION in this section, and SATELLITE COMMUNICATIONS in section 6) Internet access is available to all users, but is limited by a quota system.  All scientists are required to sign up for ship accounts.  This account allows access to the internet. This account is temporary for each scientist and crew and will be removed at the conclusion of each project.  Be sure to forward any important email to a personal email address. Use of the ship's SMTP server is recommended for sending out email, in-lieu of your personal SMTPS/IMAP service.  This guarantees that your email will be sent, as our services were designed with the satellite system in mind.  

There are public terminals on Sally Ride.  Due to the very limited bandwidth of the satellite service, we highly stress that you be mindful of other users in the ship.  Be sensible in browsing content in the internet, and ask the Computing Resources technician if you are required to handle large files over the Internet.  

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.

Hand lamps, flashlights, etc. can be obtained through the resident technician. Supply is limited; large scientific parties should provide their own units.


FRESH WATER - Fresh water generation capacity is about 5,600 gals/day.  The ship also has an evaporation distiller which puts out very pure water that can be used to fill carboys. Potable water tank capacity is about 14,000 gals. A Milli-Q Advantage system is installed in the main lab to provide pure water for lab 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 -  There are four gas cylinder storage braces in the main lab. Other hardware can be secured as necessary. 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 Sally Ride does not. Small amounts of gasoline for outboard motor use at sea are carried in USCG-approved containers. If larger amounts of gasoline are needed, a special "portable" tank can be placed aboard--but it must be requested in advance from the resident technician.


GEOLOGICAL SAMPLING EQUIPMENT - Gravity coring equipment, a box corer, a multicorer, a glass corer, and rock dredges are maintained by the Resident Marine Technician Group. A researcher planning use of any of the above equipment during an expedition should make this need known during the pre-cruise conference or before. The size and weight of geologic sampling gear make it expensive or impossible to ship commercially.

Liners PVC tubing are used with both gravity and piston corers. This liner deteriorates during long storage. Each researcher should determine his needs. The Resident Marine Technician Group can buy a liner, on a recharge basis, gauge it for size and load it on board before an expedition.

Detailed plans for projected use should be submitted with the longest possible lead time to allow for assured supply of critical items, such as pipe liner for core barrels, and dredging supplies. (See "Sampling Equipment maintained by Resident Marine Technicians" in Section 5.)

GYRO - Seapath 330+ and IXSEA PHINS are the two main MRU's used for the various scientific sensors aboard the vessel. 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.

HOLD - (See description of storerooms under LABORATORY SPACES in this section.)

HOODS - There are three fume hoods, two in the main lab and one in the wet lab.

HYDRAULIC SYSTEM - (See also A-FRAME and CRANES in this section.) The A-frame is hydraulically operated, as are all cranes. Operating controls for the frame are located on the starboard side of the frame. 

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 Sally Ride) well in advance.

HYDROWINCH - (See WINCHES in this section.)

INFORMATION SYSTEMS AND DATA ACQUISITION - Shipboard computer systems consists of a set of servers that provides email, intranet, NAS, DHCP, SAMBA, Active Directory, data processing, and data procurement services; using HiSeasNet and/or FleetBroadBand for Internet, with shore cellular network (3G, 4G/LTE) as available. In addition to the cluster, there's a wide array of data acquisition computers connected to a display array in the main lab. These provide live feedback of the ship's underway data, where it can all be viewed in the main lab. There are repeating displays in the main lab that show MET and navigation data.

There is multipurpose, low gauge, stranded, STP cable that goes to various locations around the ship, that can be used for a variety of purposes: serial feeds, power, some other data types, network. We have NMEA over UDP, wired and wirelessly. Also do serial over IP; as in use actual serial terminations for instruments and equipment that still require a DB9/25 connector, but have the transmit done via our existing network.

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 15-minute intervals using NAS. All acquisition computers have cold spares in an event of a system failure. All systems in the computer lab are powered through ship’s UPS. Some of the permanently installed data acquisition systems include (see also separate entries for these items):

  • RD Instruments 38, 150, and 300 kHz acoustic doppler current profiler (ADCP), running University of Hawaii's UHDAS software.

  • Turo Quoll XBT system, used with Sippican Fast Deep probes

  • Kongsberg EM122 and EM712 bathymetric mapping systems

  • Knudsen Engineering 3260 3.5 & 12 kHz singlebeam echosounder sub-bottom survey system

  • Seapath 330+ and IXSEA PHINS are the main MRU's for our acquisition systems.

  • Trimble BD982 GPS provide time, position, heading, and attitude information at various frequencies for the science equipment, and can be viewed on a display in the main lab.

  • MET meteorological system that provides wind speed/direction, relative humidity, barometric pressure, long and shortwave radiation, air temperature, sea surface temperature, and precipitation.

There are two Windows-based terminals for anyone with a ship account to use the Internet, and to access local ship scientific data. A printer 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, data, and cameras. 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 the lab, and can be configured by the Computer Resources technician. 

A computer technician from Computing Resources operates and maintains the computer equipment and the standard data acquisition equipment.  He or she will be able to assist in ship account creation, general IT services, science equipment repair, interfacing with the acquisition machine, data downloading, and limited data processing. At the end of a cruise, he or she will provide the entire cruise data set that was collected all systems to the chief scientist.

Due to the nature of Internet at sea (see also SATELLITE COMMUNICATIONS in section 6), Internet will be slow. Everyone has Internet access, but is limited by a quota system. 
Specialized real-time data acquisition can be arranged by prior arrangement with the Computing Resources Group.


IMCOS - Integrates shipboard communications, including the public address and alarm systems, CCTV, VoIP, LAN, and TV signal.


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.

Both labs and storeroom 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 resident technician.

In sequence from bow to stern and main deck to 1st platform, these spaces are:

  • Computer Lab 311 sq. ft. This is the location of most of the deck electronics for quasi-permanent scientific electronics - multibeam, 3.5/12 kHz system, ADCP etc. The primary work site for the Computer Resources Group technician is here, as are the hubs of the data and video networks and science information system. 

  • Main Lab 1,109 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 two fume hoods. The lab has a secondary control station for lab control of trawl winch, needs prior arrangements.

  • Climate control chambers (2) 50 sq. ft. each 
    A walk-in chamber, one accessible from the main lab, the other from the wet lab; the temperature may be controlled from 20 to -40 C, see restech for temperature setting. There are adjustable shelving units in each.

  • Wet Lab 372 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 303 sq. ft. 
    A sheltered workspace. Clearance from overhead to deck is 15 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 hoist is installed; 6,000 lb capacity.

  • Science storeroom 347 sq. ft. 
    Science storeroom, forward of the winch room on the 1st platform. A pallet-sized (85”x92” hatch to the storeroom opens to the main deck just outboard of the starboard roll-up door of the staging bay.

MAGNETOMETER - (See SONAR in this section.)

MASTS - Sally Ride has a mainmast, and a jackstaff. The main mast, above the pilot house, carries radar antennas, navigation lights, various antennas, the ship's anemometers, and flag halyards.

A suite of scientific meteorological sensors (see MET in this section) is on the bow of the ship, on a science mast.

MULTIBEAM - (See SONAR in this section.)

PRINTERS - Networked. 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 LaserJet Enterprise M750dn (main lab):

  • HP  DesignJet 510 42” (main lab) -- this is a large-format plotter:

PROPULSION - Sally Ride is equipped with variable pitch propellers connected to the motor via electric direct drive. A White-Gill azimuthing water-pump bow thruster and Schottel stern tunnel thruster are 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 or the HiPAP system. Sally Ride 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 Sally Ride. Permission to use radioisotopes must be obtained from the SIO Ship Scheduling Office 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 to the resident technicians. Cleanup costs of any isotope spills will be charged to the persons responsible.

REFRIGERATION AND FREEZING - (See also "Climate Control Chamber" under LABORATORY SPACES in this section.) There are two walk-in lab refrigerators on the ship, one each in the main lab and wet lab. The ship's cold food storage is NOT available for scientific use. Portable chest-type and -20C and -80C freezers are available upon request.

SCUBA DIVING - All diving from SIO vessels is controlled by the diving officer. Each diver must have a valid University of California Certified Diver Card or have been approved by the diving officer prior to every diving operation. Please obtain a Diving Form from the SIO Ship Scheduling Office. Your dive plan, submitted on this form, must be received and reviewed for approval well in advance of the voyage.

There is no decompression chamber on R/V Sally Ride. Arrangements can be made with STS to have a portable scuba air compressor, tanks and weights put on board.

SEAWATER - There are multiple bibs for seawater incubations on the weather decks. Checking with the deck watch officer is appropriate before hooking up and using any hoses. Seawater for wash down is available on request. For quantity, flow rate, etc., check with the engineer. See UNCONTAMINATED SEAWATER in this section for more on feeds to the labs.

SHEAVES & BLOCKS - Use of various winches and wires implies use of certain combinations of sheaves and blocks. In addition, your scientific operation may have particular requirements for fair-leading wires to certain locations. Be sure to check with the resident 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 Sally Ride often necessitates shipping equipment and samples. Commercial containers are arranged by the Resident Technician Group. 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. Please try to consolidate dealings with the agent through either the captain or the resident technician. Agents should be advised of waybill numbers so they can arrange for transportation, storage and customs. (See also CUSTOMS in this section.)

SONAR - The placement of transducers on the ship’s hull was designed for minimal bubble sweepdown interference.

ACOUSTIC DOPPLER CURRENT PROFILER (ADCP) - Sally Ride has an RD Instruments 38 kHz, 150 kHz, and 300 kHz ADCP installed which provides vertical profiles of ocean current speed and direction. The system utilizes the doppler effect to measure currents in the water column. 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 in the main lab. 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 GPS. Heading corrections are derived from the ship’s motion reference and GPS systems -- these corrections are applied to the data in real-time. Deck boxes are located in the transceiver room.

DOPPLER LOG - A JRC NKF-772 doppler speed log is installed in the chart room for ship speed measurements. 

    FISHERIES RESEARCH - Simrad EK80 with five frequencies - 18, 38, 70, 120 and 200 kHz. Deck boxes are located in the transceiver room.

HiPAP -  Kongsberg 101 (12 kHz, range to 10,000 m) and 501 (30 kHz, range to 4,000 m) acoustic positioning system. Kongsberg cNODE (12 and 30 kHz) emote transponders can be placed on deployed equipment such as an ROV or net in order to provide the position of that gear in the water column. Deck box is located in the computer lab, transceivers are located in the HiPAP room, inboard of the computer lab.

K-SYNC -  Kongsberg unit with 8 channels, located in computer lab. Increases data quality by reducing interference from multiple echosounding instrumentation outputs. All echosounders onboard are interfaced, and can be set up in a configuration best suited to the scientific goals of each cruise. Consult a computing resources technician in advance to optimize the setup.

MAGNETOMETER - R/V Sally Ride does not routinely carry a Marine Magnetics magnetometer, but it can be arranged. Contact restech in advance.

MULTIBEAM - Deck boxes and other units are located in the transceiver room.

  • Kongsberg EM122 12 kHz, 150 degree swath mapping system, max depth 11,000 m

  • Kongsberg EM712 40-100 kHz, 140 degree swath coverage sector, max depth 3,500 m

  • Beams map up to 6 times the water depth (up to 30 km swaths in deep water)

  • Turo Quoll Expendable Bathythermograph System (XBT) (one probe per day, or as needed)

  • Hardware: AMD Opteron 6300 series, 16GB ECC RAM, boot drive is an SSD, with three large storage disks for local data, Windows 10, discrete Nvidia graphics. One spare, and one each running either the EM122 and EM712. 

  • Software: Kongsberg SIS (Seafloor Information System) provides a proprietary real-time processed 3D visual data. University of Hawaii MOSAIC real-time display, an open source real-time multi beam data processing software, is popular to provide decent visual backscatter data. A variety of post-processing software packages including MB-System, GMT, and CARIS can be made available upon request.

    SINGLEBEAM - There is an array of 16 Massa TR-1075 transducers which operate at 3.5 kHz and an Airmar CS229 that operates at 12 kHz, both connected to a Knudsen 3260 deck unit for sub-bottom profiling and/or singlebeam depth sounding. These deck units are in server racks in the transceiver room. The data is digitized and may be stored in SEG-Y format. Data is graphically displayed on the display array in the main lab.  

STORAGE - (See entries in this section under LABORATORY SPACES for scientific storeroom, GASES for storage of gas cylinders, and CHEMICALS for storage and use of lab chemicals and hazardous materials.)

SUPPLIES AND EQUIPMENT - On board R/V Sally Ride the resident technician maintains a tool box from which the scientific party can borrow tools. Return of all tools is a must. In addition, the resident technicians maintain a stock of office supplies from which scientific parties can draw. Both the tool collection and the office supply stock are modest and limited to commonly used items.

It is not possible to stock everything anyone might conceivably wish to have at sea. Researchers anticipating the use of, for example, an extensive inventory of chemical lab equipment, should consult with the resident technician and plan to supply most of their own needs. Stocking of the ship prior to the beginning of an expedition is done with the expectation of more or less steady use of the items stocked and, it is hoped, in sufficient quantity to forestall the need to re-equip in overseas ports - an unsatisfactory experience in almost every instance.

A list of inventoried supplies is available from the resident technician upon request. Local purchase of extra quantities of particular items can be arranged through him/her and should be done as far in advance of departure as possible. Supplies purchased will be recharged to the account of the requestor.

The ship does not carry a standard suite of analytical or special-use equipment. The planned use of equipment such as water sampling bottles, reversing thermometers, box corers, bottom trawls, centrifuges or ovens should be indicated on the Ship Time Request Form, and should be checked in consultation with the resident technician well in advance. (See also Section 5.)

UNCONTAMINATED SEAWATER - Uncontaminated seawater is provided via a 2-pump system in the bow thruster room connected to the lab via plastic piping. There is also an incubator pump connected to the deck for use in incubations and wash downs. Please check with duty engineer for hookups of supply and drainage.

VANS - Sally Ride can carry multiple laboratory, refrigeration, and storage vans. Two vans can be sited aft of the main lab. Two more vans can be stacked atop those, with access from the focsle deck, port side. 

Plans to use any vans should be indicated on the Ship Time Request Form and details should be discussed with the resident technician well in advance of departure.

WINCHES - The Markey traction winch with rated line pull 25,000 lbs at 45 m/min is located in the winch room on the 1st platform level. Two stowage drums can carry up to 12,000 m 9/16” 3x19 torque-balanced wire rope, 10,000 m 0.680” EM cable, or 10,000 m 0.681” EOM cable. Fiber optic cable can also be used. Wire is led overboard through the A-frame aft. 

CTD/hydro winches: Dual Markey CAST6 with motion compensation and rend & recover modes, each with rated full drum capacity of 14,000 m 0.322” electro-mechanical (EM) cable, 12,000 m 0.375” 3x19 torque-balanced wire rope, or 10,000 m 0.393” electro-optical-mechanical (EOM) cable. Wires lead over starboard side via Allied crane articulating booms.

A towed magnetometer with winch can be carried on the fantail, see SONAR, MAGNETOMETER in this section for details.

Assorted portable winch and wire combinations available for cruise-specific requirements.


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 resident 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.
