Section 3: 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.

04 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 welcome. 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-dial sound-power telephone systems and airphone intercom.

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. Check with the mate on watch before borrowing any of these items. (See also LABORATORY SPACES in Section 4.)

Communications equipment is located in the chart room; the mate on watch will operate it and/or assist you to do so. R/V Roger Revelle 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.

AFT CONTROL STATION - A secondary control station with winch controls and ship maneuvering controls is located aft on this level. The usual site for ship control is in the pilot house, and the usual sites for control of the winches are on the 03 level for the hydrographic and CTD winches, and above the fantail for the trawl winch.



03 Deck

CHIEF SCIENTIST'S STATEROOM - The chief scientist's room has one bunk plus ample bookshelf, file, and desk space to serve as an office. The room has computer network connections and a shipboard telephone.

CAPTAIN'S STATEROOM - Adjacent to the chief scientist's room is the captain's room, which also serves as the captain's office.

SCIENTIFIC STATEROOMS - There are four scientific staterooms on this level, each with two bunks. Rooms are small with no desks, but are the quietest aboard.



02 Deck

CRANE - Two North American MCT-1565 cranes are permanently mounted on the ship, one on the port side 02 level and one on the main deck starboard quarter.

DECK - The 02 deck has space available on the forward deck for four standard vans, and for additional items forward of these vans, provided the items are not tall enough to block the line of sight from the pilot house to the bow.

HOSPITAL - There are 5 bunks and various medical supplies. (See Section VII for more on medical matters.)

HYDROBOOM - The hydroboom is used for launching and recovering oceanographic equipment and fairleading wire from the hydrographic winches. Controlled from the forward Winch Control Station. Various block/sheave combinations are available.

HYDROGRAPHIC WINCHES - One Markey DESH 5 winch equipped with either hydrographic wire or 0.322" CTD cable,  is located on the 02 level forward of the staging bay. Wire is led over the starboard side via blocks on the end of a retractable boom at the level of the top of the staging bay. Check your wire requirements.

One CAST-6/ Allied Crane CTD Handling System equipped with 0.322” CTD cable Is located just above the hangar, with boom head directly over the starboard hangar door when stowed.

INSTRUMENT WELL HATCH - This is a hatch aligned with the 24-inch diameter through-hull instrument well that opens in the deck of the staging bay 20 ft below. (See INSTRUMENT WELL in Section 4.)

LIFE RAFTS - All eight of the ship's life rafts are located on the 02 level forward.

STATEROOMS - There are four staterooms for ship's officers and one scientific stateroom on this level. This latter stateroom has one bunk plus a pullman berth, and has a private head. (See Section IX for specifics.)

WINCH CONTROL - Primary site for control of CTD and hydro winches is on the 03 level, with good view of both winches and the starboard-side water entry point.



01 Deck

INCINERATOR ROOM - The ship normally burns plastic trash once a day, to keep ahead of the accumulation. If your science operations will be compromised by trash burning, please consult with the resident technicians well in advance of your cruise. Depending on the amount of interference and the amounts of trash generated it may prove necessary to carry an extra van to hold trash until it can be burned or otherwise disposed. No trash is thrown overboard in accordance with international regulations.

CONFERENCE ROOM/LIBRARY - This area is designated as a quiet space on the ship for reading or studying. It is separated from the mess deck by a folding door. Good place for meetings. It contains a public terminal PC and one of the ship's copy machines (another is in the science office, main deck). Food and drink are not allowed in this space, to keep carpeting and upholstery clean.

CRANE - On the foredeck, starboard side, is a Morgan Marine 18,000 portable deck crane. It cannot be moved with out shore assistance. DMG 1200 extension crane located aft of rescue boat on 01 level stbd side.

(D)AMAGE (C)ONTROL LOCKERS - DC lockers are located amidships, starboard, aft of the galley and main deck forward in port side of scientific cargo hold. (See also DC LOCKER under MAIN DECK, this section.)

GALLEY & CAFETERIA - The mess hall is located amidships. For safety and public health reasons only the cooks and other authorized crew members are permitted in the galley food preparation area. Food is served cafeteria style. (See Section 8 for more details on mess hall hours and practices.)

SHIP'S LOUNGE - Located forward of the galley on the starboard side is the lounge. This space contains a TV, VCR, and AM/FM stereo system.

STATEROOMS - Eight crew staterooms are on the 01 level.

RESCUE BOAT - The ship's rescue boat, a semi-rigid type, is located on the 01 level, starboard.

WORK BOAT - Depending on how many vans are carried, and in what locations, the ship's Hurricane work boat in its relocatable cradle may be situated on the 01 level aft, port side. The cradle is difficult to relocate at sea. Please pre-plan. (See BOATS in Section 4.)

SCIENTIFIC STOREROOM (FORWARD) - The forward scientific storeroom is at the forward end of the main deck passageway. It is served by a hatch that opens on the 01 deck forward and accessible internally via double doors and widened passageway. All labs are accessible to this storeroom at sea or in port.

STAGING BAY - A high-overhead sheltered (not weatherproof) work space with roll-down doors starboard and aft, and deck hatches to the lower scientific storeroom and the instrument well.



1st Platform

ENGINEERING SPACES AND SERVICES - These are off-limits to scientific party members except by permission of the chief engineer or the duty engineer, especially when cruising. They can be dangerous at any time, due to the possible hazard of noise, oil, grease, or lubricants underfoot.

All questions of an engineering nature and requests for services or help should go to the chief engineer or engineer on watch in port; at sea requests for assistance should go via the bridge. Engineers are helpful and knowledgeable, but they can assist scientists only after completion of their regular duties.

MACHINERY CONTROL ROOM - Propulsion machinery and electrical plant controls.

MACHINE SHOP - Forward of the machinery control room, and on the port side. The shop has a lathe, drill press, etc. By permission of the chief engineer, science party members who demonstrate the requisite experience and ability may use these tools.

PROPULSION MOTOR ROOM - Propulsion machinery. This area is in the aftermost part of the ship. It is an unmanned space. Access by nonessential personnel is restricted, due to the hazards of the high-power electrical equipment here.

SCIENCE STOREROOM (LOWER) - Located aft of the upper engine room and switchboard room, and forward of the winch room, this is a second scientific storage area. A portion of the port side of this room is devoted to engineering stores. Access at sea is limited to what can be hand carried up the ladder. In port, flush deck hatches can be opened.

STATEROOMS - There are berths for 30 persons, 24 scientists and 6 crew, on the first platform. (See Section 9: Scientific Berthing Plan for specifics.)

TRAWL WINCH ROOM - This room contains the Markey two-drum main traction winch system, and fairleads by which wires can be led to the A-frame or the heavy crane on the starboard quarter.
