Design and Construction

ATLANTIS II was built to U.S. Navy specifications with super redundancy out of special German high tensile steel alloy to ABS and Ice Class. She had her international load line and COI until 1996. Recently having completed a refit, she is able to be either re-classed and / or receive COI or load line. As quoted from a Marine Survey Report of November 1999: "The vessel was built of all welded steel construction by Maryland Shipbuilding Company, Baltimore, Maryland, in 1961 / 62. The vessel underwent extensive refitting in 1979, converting the vessel from steam to diesel power. A stern deck equipment hanger and a large ROV tending A-frame were added in 1983 for use with a large submersible. The A-frame has since been removed, but the foundation and hydraulic systems remain. The vessel is presently undergoing refurbishment and modernization. The vessel is of a typical ocean service, research design with a model bow, transom stern, sheer main deck with forward forecastle, and a two-and-one-half-deck steel superstructure containing quarters, and spaces that have in the past been used for laboratories and research. The vessel's hull is protected by means of a two-tier rub rail fender system constructed of 6" diameter split pipe. The upper strake is located at the forecastle deck elevation and runs from a point 30' aft of the bow aft to the break of the forecastle on both port and starboard sides. The second strake is located at the main deck elevation and runs from a point 40' aft of the bow, aft to a point 24' aft of the break of the forecastle on both port and starboard sides. Bulwarks are constructed of steel, of the open type, with a height forward in way of the forecastle of 48", tapering to a height of 42" in way of the mid-portion of the forecastle deck, and fairing into a three-tier 42" high pipe safety rail in way of the aft end of the forecastle deck. Bulwarks in way of the aft deck have a height of 30" and are of a similar design. Bulwarks are fitted with adequate freeing ports. Deck fittings consist of the following: Located to port and starboard on the foredeck are 10" diameter cast steel double bitts with adjacent 16" closed chocks. Located to port and starboard aft on the foredeck are 10" diameter cast steel double bitts with adjacent 16" closed chocks and 12" open chocks. In way of the after end of the forecastle deck level three (3) 6" diameter steel H-bitts range down the port side while one (1) is located on the starboard side. Located to port and starboard on the aft deck are 6" diameter bitts with adjacent 18" closed chocks, each chock fitted with four (4) securing horns, and adjacent 6" diameter closed chocks, each chock fitted with two (2) securing horns. An American Engineering 18" diameter warping capstan is located to starboard on the aft deck. Ground tackle consists on one (1) each port and starboard bow Baldt 3,30-lb. anchor, each fitted with a reported seven (7) shots of 1-7/16" stud link chain. The anchors are handled by a double wildcat, double 18" diameter gypsy head, Skagit model WE1HWG-23-6 anchor windlass powered by a 25-hp electric motor. The vessel also has on board, located on the foredeck, a spare 1200 lb. anchor. Bulkheads are constructed of steel and are designed watertight, with watertight doors located at strategic areas throughout the vessel as noted below. The fuel oil tanks noted above have a total reported capacity of 109,760-gallons and are fitted with approved type filling lines, vents with flame screens, and fuel oil shut-off valves. Fresh water capacity is reported to be 26,600 gallons with an additional evaporator capacity of 4800 gallons per day. Lead ballast is reported to be 271 long tons. The deckhouse is constructed of steel and is fitted with steel watertight doors, port lights, and fixed windows. The interior of the vessel is centrally air conditioned by means of forward and aft centralized chill water air conditioning units, and heated by means of boiler-heated radiators and electric space heaters. The vessel is arranged with passenger / scientist accommodation, auxiliary work and support rooms on the lower deck level within the hull; stores, galley / messing, officer and crew accommodation and laboratory spaces on the main deck level; senior officer and passenger / scientist accommodation, a library, gymnasium and a store on the 01 (upper) deck level; ship support, electronic support and crew accommodation on the 02 deck level; the pilothouse, radio room, and chart room on the bridge deck; and a full bar / lounge located on top and behind the pilothouse".
