The LNG carrier Gastor has been delivered from St Nazaire to her owners, Zodiac Shipping (of Curacao). The second ship of this series is scheduled for delivery in late summer 1977 to Odyssey Trading Co., Bermuda. Both ships have been chartered by Pacific Lighting Co., Los Angeles, for the transport of LNG from northern Sumatra to California for a 20-year period commencing in 1979. The ship has five main cargo-tanks, with a small No. 6 tank (1,734 cubic meters) in which LNG is carried during ballast voyages and used to cool the main tanks before the ship arrives for loading. Nos. 1, 3, and 5 tanks, and Nos. 2, 4, and 6 tanks, form separate groups for the carriage of two different cargoes. The tanks have two immersed pumps each, giving a total unloading time of about 16 hr. The tanks are of the invar-steel membrane type; the Gaz Transport tank system used is similar to that in El Paso Paul Kayser. Nitrogen for inerting is carried in two 30-cubic meters tanks on the weather deck. Loading rate is about 10,000 cubic meters/hr; deballasting can be carried out simultaneously. Cargo handling is controlled from a cargo control room amidships on the weather deck. LNG boil-off, about 0.22% per day, is utilised as fuel, LPG boil-off is reliquefied in a plant which could easily be adapted for LNG if its reliquefaction should, in the future, become more economical than burning it as fuel. It is mentioned that two vessels to be built after the present two will have combined LPG and LNG plant. The article gives further information on the ship and, in particular, her cargo arrangements, and includes general-arrangement and engine-room drawings.
