Abstract: A method for re-gasification of LNG in which method natural gas is combusted in a burner to provide heat for evaporation of the LNG and where the heat is transferred from the burner to the LNG in a closed heat exchange system, wherein substantially pure oxygen is used in the combustion of natural gas, and that C02 is separated from the exhaust gas for export or deposition, is described. A plant for re-gasification of LNG, the plant comprising a gas fired burner (14) for generation of heat for the re-gasification, a closed heat exchange system (5, 17,25) for transfer of heat from the burner to LNG to be vaporized, the plant additionally comprising a air separation unit (10) for generation of substantially pure oxygen to be fed to the burner (14), is also described.

Abstract: A tether system include tethers each having an upper section (1) attached to a tension leg platform (TLP) (4), and each upper section has a large diameter so that the upper section (1) is positively bouyant. This buoyancy can be designed to compensate for the weight of the lower section (2) of each tether, so as to make the total buoyancy of each tether closer to neutral. The selection process for each section is driven by requirements for buoyancy, stiffness and external pressure resistance.
