This ship includes a ship body, a fuel tank chamber, a stern-side engine room, a bow-side engine room, a main fuel line and a sub-fuel line, and a pump mechanism. The main fuel line connects a fuel tank, a stern-side power generation unit, and a bow-side power generation unit through the bow-side engine room. The sub-fuel line connects at least the fuel tank and the stern-side power generation unit, and is disposed through a section different from the bow-side engine room through which the main fuel line passes. The pump mechanism selectively feeds fuel into the main fuel line or the sub-fuel line from the fuel tank.

A single, unitary fuel/oil manifold for a gas turbine engine is provided which comprises one or more interfaces for mounting various fuel system and lubricating system components directly to the fuel/oil manifold. The fuel/oil manifold also defines fluid passages for transferring fuel or lubricant from one component to another component. Packing numerous fuel system and lubricating system components within the fuel/oil manifold reduces cost and weight and simplifies maintenance.

A torch device includes an arm operatively coupled to a supply line that is electrically coupled to a power supply and in flow communication with a fuel tank. A distal end of the arm includes a nozzle positioned adjacent to a fuel ignition system. A mount removably couples the arm to the torch device, such that the arm is configured to be used in a first use position that includes the arm removably coupled to the mount and in a second use position that includes the arm removed from the mount. The supply line is secured to a first end of the arm, extends through the arm, and has a length such that the arm can be used in the second use position up to a distance from the fuel tank approximately equivalent to the length of the supply line.

A liquid fuel portable heater (100) comprises: a combustion chamber (101) having a fuel inlet with a nebuliser (13); an electric pump (10) having an inlet (11) for suctioning said liquid fuel from a tank (6), and an outlet (12) connected to said nebuliser (13); a control unit (20) configured so that, when the heater (100) is turned on, said control unit (20) supplies the electric pump with a sequence of pulses (115, 115) with a non-zero voltage, and pause intervals (116) with a substantially zero voltage alternating with said pulses, wherein the average duration of the pulses (115, 115) is less than the average duration of the pause intervals (116). In addition, a method for controlling an electric power supply of a fuel electric pump (10) of a liquid fuel portable heater by means of an electric control unit (20) configured to control said electric power supply, comprising a step of electrically supplying said pump, once the heater is turned on, with a sequence of pulses (115, 115) with a non-zero voltage, and pause intervals (116) with a substantially zero voltage alternating with said pulses, wherein the average duration of the pulses (115, 115) is less than the average duration of the pause intervals (116).
