Abstract: An exhaust system (10) for a dual fuel engine comprising a catalyst assembly comprising a first catalyst (4) comprising a methane oxidizing catalyst and a second catalyst (6) comprising a selective catalytic reduction catalyst, the first catalyst (4) being positioned upstream of the second catalyst (6).

Abstract: A storage tank assembly for storage of cryogenic liquids including a first outer tank and a second, inner tank, the first and second tanks being spaced apart from one another to form an insulation space therebetween. Each of the first and second tanks has a first end, and an opposite second end spaced apart from the first end, and a wall extending from the first end to the second end. The assembly further includes a pipe work system comprising a plurality of pipes and a first connector extending through the wall of the first tank, the pipe work being connectable to the first connector such that the pipe work is spaced apart from the wall of the first tank.

Abstract: An exhaust system (10) for a dual fuel engine, which engine is adapted to operate in a first mode in which the engine is fuelled entirely by a liquid fuel, and a second mode in which the engine is fuelled predominately by a gaseous fuel, the system comprising a first oxidation catalyst (22), a first temperature sensor (30) adapted to measure a core temperature of the first oxidation catalyst, and a controller (32) for controlling whether the engine operates in the first mode or the second mode, wherein the first temperature sensor is operatively connectable to the controller such that the controller prevents the engine from running in the second mode if the core temperature of the first oxidation catalyst is below a predetermined temperature.
