EUROPEAN UPDATE at minimum free board is 5,200 tons (21-ft. draft). To achieve the speed requirements, the ves- sels will be powered diesel-electrically with each having four generator sets producing total outputs of around 3,600 kW, allowing an antic- ipated 2,800 kW of shaft power for propulsion purposes. Two variable speed drives, normally operating in unison, will provide a stepless variation from full speed ahead to full speed astern. Exact details of the generators have not yet been released, but according to the yard, the individual units are to be sized to cater, in the most economical manner, to seven designated operating conditions which include full speed and service speed and maneuvering, together with three in port load demands — idle, full cargo pumping and tank washing. Considerable thought has been given to the cargo arrangements which are designed to accommodate all materials listed in the IMO IBC code, with the exceptions of carbon disul- phide, hydrogen peroxide and molten sulphur. The vessels will also be equipped to carry any grade of refined petroleum product. Each of the 16 tanks is fitted with its own hydraulically-dri- ven, 200-cu-m/hr. deepwell pump, handling cargo with specific gravities between .7 and 2.2. All cargo operations, including control of pumps and valves, monitoring of cargo tanks, ballast and stripping, tank cleaning, bilge, fuel, nitrogen, dehumidified air and vapor control will be remotely operated and monitored as part of an integrated system from a dedicated cargo control room. Although a full specifica- tion of the bridge fitout has not been announced, the vessels will be classed to a host of DNV and RINA notations including W1 - one person bridge operation in ocean and coastal waters. The vessels will therefore be equipped with integrated bridge systems and main propulsion, 500-kW bowthrusters and rudders, controlled from the central position and bridge wings. All actions will be recorded on an inte- grated computer. The final selection of elec- tronics is being made to ensure compliance with GMDSS A3 standard. Two sets of combined anchor windlasses/winches will also be capable of being controlled from three positions on the bridge in addition to local operation. Use of a well-insulated, prefabricated system will provide a high standard of accommodation for 14 passengers in 10 single cabins and two doubles, all equipped with toilet and shower facilities. An additional day room is included in the quarters of captain and chief engineer. The duty mess room for six is augmented by a sepa- rate day room/mess for both officers and crew, and a conference room is incorporated at bridge level. Completion of the first vessel is scheduled for December 1997, followed at four monthly inter- vals by the next two. The three remaining ves- sels in the series are subject to an option.
