Abstract: A system for circulating air through double pipes for supplying gas, includes double pipes connected to a gas handling device and supplied with gas; a gas supply unit for supplying gas to the gas handling device through an inner pipe of the double pipes; an air supply unit for supplying air through an outer pipe of the double pipes; and an air suctioning means for suctioning and circulating the air, which is supplied to the outer pipe by the air supply unit, by the introduction of a high pressure fluid. Rather than circulating air through the outer pipe of the double pipes by a fan, air can be circulated through the double pipes for gas supply by a simpler structure and more effective configuration.

Abstract: A four-lobe cargo tank for transporting and/or storage of liquefied gases includes four main lobes, each with a cylinder sector outer shell and main lobe axis. The four main lobes are arranged with the four main lobe axis axial-parallel with and about a common main central axis, such that the four main lobes are joined by four web frames with four corresponding diagonally arranged perforated bulkheads directed outwardly from the main central axis. The tank includes a first and a second end cover. Each end cover includes four quarter spherical shell portions, each forming an end portion of the cylinder sector outer shell. The quarter spherical shell portions of the first and second end covers, respectively, are joined and closing toward the main central axis by a first and a second four diagonally arranged cylindrical 45-degree cut pipe portions, which are each arranged with its axis transverse to the main axis.

Abstract: The invention relates to monitoring and predicting the operation of a pump (30) arranged in a tank (3) for transporting a liquid product on board a ship (1), the pump (30) having a pump-head (31) arranged in the tank (3). A tripping risk parameter of the pump (30) is estimated at least as a function of a required net positive suction head of the pump (30), of the current filling level of the tank and of a current state of movement, which is a current sea state and/or a current state of movement of the ship, and a user is provided with an indication as a function of said tripping risk parameter.
A particular application to ships for transporting a cold liquid product, more particularly to ships for transporting LNG of the type which consume the boil-off gas for their propulsion.
