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.
