摘要： A bend limiting device (100) for a cable (101') comprising at least one elongated sleeve member (104) with an entrance end (105) exhibiting an entrance opening (106) and an opposite exit end (107) exhibiting an exit opening (108) for the cable (101"), an outer abutment surface (109), disposed between the entrance end (105) and the exit end (107), for securing against a rigid surface (110) of a floating marine installation (103) or vessel, an axially th rough-going hole (111) between the entrance opening (106) and the exit opening (108) for accommodating a portion (101"') of the cable, and at least one clamping device (112) for securing said sleeve member (104) in a fixed position a round the cable portion (101"). The outer abutment surface (109) of the sleeve member (104) is configured to allow it to be secured against the rigid surface (110) by applying a pulling force (Fl) on the cable (101) in a direction from the abutment surface (109) to the rigid surface (110), as well as to be detached from the rigid surface (110) when the application of pulling force on the cable ceases,

摘要： A wave energy converter includes a buoyant body and an acceleration tube with a working cylinder and working piston movable therein, a mooring system, and at least one energy collecting device including a differential cylinder having an internal pump piston connected to the working piston via a piston rod. The differential cylinder includes a pumping chamber and an annular pumping chamber. When decreasing volume of the annular gap-shaped pumping chamber, the pump piston expels hydraulic fluid from the pumping chamber toward the pressure accumulator and draws hydraulic fluid from the fluid tank into the substantially cylindrical pumping chamber. During a working stroke causing a decrease in volume of the substantially cylindrical pumping chamber, the pump piston causes hydraulic fluid to bypass the pump piston through a fluid connection from the substantially cylindrical pumping chamber into the annular gap-shaped pumping chamber and further in a direction toward the pressure accumulator.

摘要： A wave energy converter includes a buoyant body and an acceleration tube attached thereto forming a working cylinder. Upper and lower openings in the acceleration tube allow water flow between the working cylinder and the water in which the acceleration tube is at least partially submerged. A working piston is reciprocable in the working cylinder and an energy converting device collects energy from the movements of the working piston relative to the buoyant body. A mooring system maintains the wave energy converter within a desired anchoring area and includes at least a first fastening device mounted on the buoyant body for attachment of a first mooring line to the buoyant body and a second fastening device mounted on the buoyant body for attachment of a second mooring line to the buoyant body. The mooring lines include first and second line sections, respectively, and at least one buoyant element attached therebetween.
