Failures of offshore mooring steel wire ropes Arne Kvitrud, Sigmund Andreassen and Marita Halsne Petroleum Safety Authority Norway (PSA) Stavanger, Norway ABSTRACT Steel wire ropes use individual wires moving relative to each other in a spherical structure. The behaviour of wire ropes exposed...

... ropes, and the wire ropes transmit tensions acting on the lifting system. The block loader makes tension distributed evenly on wire ropes and sheaves. The trolley holds a block loader and moves along the crane. The motion of the lifting system is determined by a lug arrangement. The lug arrangement...

... from the actual impact on rockfall barrier system. During the test, Scene of experiments were recorded by high speed camera to analyze the real behavior of materials such as wire netting, wire rope and steel posts. As a result of the test, the stress of wire ropes increases with rising rockfall energy...

... ABSTRACT Cables, as well as wire rope and flexible pipe, are long, thin structures primarily used to carry tensile loads over straight and curved paths. The internal helical geometry of these structures helps to keep stresses due to bending low, but torsional effects can be significant...

... structure, cranes, and barge, all of which are moored and connected using wire ropes, are analyzed. Second, tensions in the wire ropes connecting the cranes and the offshore structures are calculated. Finally, any collision between the offshore structure and the cranes or the barge that transports...

.... By this simulation, one can confirm the dynamic effects, such as dynamic motion and load, to prevent fatal accidents during the multi-crane operation. The crane system consists of several bodies. These bodies are connected with various types of joints and wire rope. To carry out the dynamic simulation, therefore...
