Vessel Layout Description
This section is intended as an abbreviated tour of important spaces and equipment, in conjunction with ship arrangement diagrams. Most spaces and equipment of interest to scientists have fuller descriptions in Sections IV - VI.
03 DECK (Bridge)
BRIDGE OR PILOTHOUSE - This is the nerve center of a ship. From this area the ship is navigated, conned, maneuvered and otherwise operated in such a manner as to accomplish the goals of the cruise safely and effectively. Additionally, operational aspects of the engineering department and the scientific party are monitored by the bridge watch officer. The watch officer maintains a log which records the date, time, and position of all scientific events. A copy of this log is given to chief scientists and others who request it at the end of the cruise. Visitors to the bridge are generally . There will be times, though, such as when entering or leaving a harbor, when visitors are not permitted; check with the officer of the watch. Equipment, controls, and instruments on the bridge are operated only by the crew. Communication with the bridge is by ship's interior communication boxes and sound-power telephones.
CHART/RADIO ROOM - The chart room is located aft of the pilot house. The progress of the ship is plotted on charts in this room. It is also where the ship's inventory of charts and navigational publications are stowed and maintained. Some important texts on navigation, seamanship, meteorology and nautical information in general are stowed here, in addition to user manuals for most of the ship's installed equipment. Check with the mate on watch before borrowing any of these items. The 02 lab is used for manual plotting and map handling by the scientific party. (See also Laboratory Spaces on Main Deck)
CHIEF SCIENTIST'S STATEROOM - Two berths are available in the chief scientist's stateroom, one is the permanent bunk, and the other is a comfortable sofa which converts to a bed.
CAPTAIN'S STATEROOM - Adjacent to the chief scientist's room is the captain's room. This is where the captain has an office.
SCIENTIFIC CHART ROOM - You will find a chart table, chart drawers, storage cabinets, and one filing cabinet. The area is approximately 440 sq ft and does contain bolt downs on the deck.
HYDRO WINCH CONTROL HOUSE - (See Winch Control Room)
RESCUE BOAT / LIFEBOAT - On the port side there is a 28 person lifeboat and starboard side a 37 person lifeboat. There are life rafts in the following areas: 3 starboard, 3 port, 20 persons each.
DECK ACCESS TO CARGO TRUNK - There is an approximately 5' x 5' access via a flush deck hatch. (Note: This hatch has been re-hinged on the starboard side to allow it to open fully.)
RADIO ROOM - Most communications with shoreside facilities take place in this area. Melville is capable of voice, data, and fax communications through various modes. Persons wishing to use the Inmarsat system must be aware that this is a commercial system and that they are responsible for charges incurred. Presently, all facsimiles must be sent via either Inmarsat or cellular.
INCINERATOR ROOM - The ship normally burns plastic trash once a day.
LIBRARY - This area is designated as a quiet space on the ship for reading or studying. It does contain the ship's only copy machine.
STATEROOMS - The chief mate's, radio officer's, and chief engineer's staterooms are berthed on this deck, as are three scientific staterooms. These staterooms are two person rooms each containing private heads. (See Section IX for specifics.)
CRANES - Two cranes are located on the 01 deck. Forward on starboard side is a 60' boom Pettibone crane. This crane is capable of lifting 3,540 lbs maximum reach at sea. An Allied crane is located near the centerline aft serving the main deck area. This crane has a 65' knuckle boom capable of lifting 12,000 lbs near the base and 5,000 lbs at maximum reach (rated at 5,000 lbs SWL at sea). These two cranes are operated by the resident technician or qualified crew members only.
A portable crane (either a Daybrook or Alaska crane) can be carried on the fantail where necessary, and can be operated by the scientific party. These cranes are rated for a capacity of 1,500 lbs and 2,000 lbs respectively.
UPPER LAB - This lab, known as the computer lab, is approximately 488 sq ft. The forward area of the lab is reserved for the computer engineer and hardware/ electronics engineer. The remainder of the lab is configured as a general use computer lab and contains terminals, PCs, printers, plotters, and a light table on a semipermanent basis. Space is also provided so oncoming scientists can set up their own PCs or other electronic equipment. A soft patch on the after bulkhead allows for access to portable lab vans on the 01 deck utilizing a flexible coupling. An approximately 3' x 5' vertical access hatch to the hoist trunk is located in the after part of the lab.
WINCH CONTROL ROOM - When the ship is on station and over-the-side work is in progress, the CTD and traction winches are controlled from this room. The location of this room permits the officer on watch to observe the proceedings on the fantail or at the hydro station and still control the ship in the required manner. The aft control room also houses the controls for the hydraulic system and winches. The hydro, CTD, and trawl winches and starboard J-frame are operated from this room. A member of the ship's crew will operate the winches.
ANALYTICAL LAB - This lab is located port side forward of the main lab and is approximately 220 sq ft. This lab usually contains a chart table, chart drawers, and a portable light table.
BOATSWAIN LOCKER - The ship's boatswain locker is located all the way forward on the main deck. Located adjacent to the boatswain locker are the paint locker and the flammable liquid storerooms. The access to the bow dome is located in the boatswain locker.
LOUNGE - Located forward on the main deck is the crew and scientific lounge. This space contains a TV, VCR, PC, and video games. Access to the bow thruster machinery room is through this space. Smoking is allowed in this area.
STATEROOMS - Six crew staterooms berthing 7 personnel are on the main deck. One scientific stateroom located next to the analytical lab contains accommodations for 2 persons with a private head.
DARKROOM / LAB - The darkroom is located on the starboard side forward of the hangar. This space contains no installed photographic facilities. Photographic supplies and equipment are the responsibility of the scientific party. A sink with fresh or salt water is installed.
