DEVELOPMENT OF A 40,000-CUBIC METER GAS CARRIER, WITH SPECIAL REFERENCE TO THE USE OF LARGE PRESSURE-TANKS

The author, of AG Weser, describes some preliminary design work for the development of an LPG/NH3 methane tanker with a cargo capacity of about 40,000 cu m. The work, which was carried out with the help of West German Government funds, was particularly concerned with the suitability of the ship's large cargo tanks, whose type (Type C) and form (horizontal figure-8) were chosen on the basis of an associated investigation. The tanks would be of fine-grain steel construction, with flanges of 5%-nickel steel. The ship would comply with the IMCO code for liquefied-gas tankers, and with the Germanischer Lloyd classification maltese cross 100 A4 MC "R" Liquid-Gas Tanker Type "II G", and its tentative dimensions are: length b.p. 185 m, breadth 28.4 m, depth 18 m, and draught about 10.3 m; trials speed would be about 17.5 knots. There would be four tanks, with the figure-8 shape of No. 1 modified to suit the hull form. Nos. 2 and 4, and Nos. 1 and 3, would constitute two groups to enable two different cargoes to be carried at the same time. Propulsion would be by a lowspeed Diesel. Some further information is given on the ship's design and equipment, and on some relevant requirements, and in particular on the extensive calculations for the tanks (which are much larger than tanks of the same type for which information is readily available) and, taking hull elasticity into account, for their seatings (the Stardyne FEM program was used for these latter calculations). A preliminary general-arrangement drawing is included. Order from BSRA as No. 49,897.
