Lloyd's Register of Shipping has given approval in principle to the Gaz-Transport/McDonnell Douglas Corporation's LNG containment system. This combines Gaz-Transport's flat 36 percent nickel-iron alloy-membrane and an improved version of the Mc- Donnell Douglas Corporation's three-dimensionally r e i n f o r c ed polyurethane foam developed for the U.S. Apollo/Saturn Lunar Exploration Program.
The Hull Structures and Refrigeration Departments have reviewed the physical strength and thermal properties of the system and recommended that this approval approval be given subject to certain conditions, including the usual one that detailed plans are to be submitted showing the configuration of the system when it is applied to a particular ship building to Lloyd's Register class.
The system consists of two layers of three-dimensionally reinforced polyurethane panels which are designed to be bonded to each other and directly to the inner hull in bricklaying fashion.
Alternatively, the polyurethane panels are bonded to plywood panels which are located by studs and supported via a network of epoxy mastic beads by the inner hull. The combined GT/MDC system is formed by applying the flat, automatically welded membrane of low thermal expansion nickel steel, over the 3D insulation.
The primary metal membrane used in the current, proven Gaz-Transport design is retained in detail in the new GT/MDC system—including the capability The Wager Inverted Vent Check Valve Sizes IV2" to large 12" Also supplied with covers.
of transmitting membrane and thermal loads into specially designed corner couplers and then to the ship's hull. The method of attaching the membrane to the insulation in the new design is also similar to the original Gaz- Transport system. The secondary barrier function is provided by the two layers of three-dimensional reinforced polyurethane insulation with an intermediate liner of glass fiber cloth bonded between layers.
