(in 1974) The current uncertainty over the price differential between LNG and bunker fuel has resulted in a 'wait and see' approach towards the reliquefaction of boil-off gas on LNG carriers. The advantages gained by reliquefaction are still apparent and will become of increasing importance in the future.

However, there has been no 'wait and see' policy with respect to tanker construction and a substantial proportion of the total projected LNG tonnage will go into service without reliquefiers installed as original equipment.

Petrocarbon Developments and Airco Cryogenics have combined their resources and expertise to produce a reliquefier package specifically designed to be 'retrofitted' on to operational LNG tankers with the minimum impact and delay. This combined approach integrates the operational requirements of performance, flexibility, reliability and safety with equipment considerations such as efficiency, manufacturing, packaging and cost. A modular concept is proposed in which the reliquefier is independent from the ship's steam system. The skid modules are assembled and fully tested prior to being installed upon the tanker within minimum site construction. This paper sets out some of the design criteria for a 'retrofit' plant and how optimum solutions are found in a combined approach between plant designer and equipment supplier.
