The evaluation indexes of structural optimization, the maximum collision force Fmax of ship bridge collision, the deformation size S of fenders, and the energy absorption E of ships or the absorption capacity E * of fenders, are the direct reflection of the excellent design of fenders. Obviously, the smaller the Fmax, the better; Under the condition of ensuring Fmax, the smaller the better, so that the bridge can be protected and the fender can not be replaced once hit

Filling operation of LNG bunkering ship usually refers to the operation that the LNG bunkering ship alongside the receiving ship and transmits LNG to the receiving ship. This operation can be carried out when the receiving vessel is berthing at the wharf, anchorage, or both vessels are sailing. During the refueling operation, the inflatable fenders usually float on the water surface to absorb the collision energy during berthing and maintain a proper balance distance between the two ships. Inflatable fender

Collision between ship and pier will not only cause damage to pier or hull structure, but also cause catastrophic consequences such as casualties and environmental pollution. Therefore, it is of great practical significance to install and design effective anti-collision fenders on bridge piers to absorb collision energy, reduce collision force between ships and bridges, and improve the safety of ships and bridges. Scholars at home and abroad have conducted a lot of research on anti-collision fenders

The float over method (float over installation method) is an installation technology that uses a barge to carry the topside of the offshore operation platform. During the installation process, the topside is lifted and lowered by means of tide level, barge load adjustment and lifting mechanism. At the same time, special connecting parts are used to complete the butt joint between the topside and the lower jacket platform. During the floating installation of offshore platform module, the module is loaded by tug

The floating installation method of offshore platform topsides has become an effective installation method since the 1980s. After years of practice and exploration in the industry, not only the weight of the installation structure is increasing, but also the installation method is constantly challenging the worse construction sea conditions. The floating method solves the contradiction that the module construction cannot be expanded due to the limitation of lifting capacity, and improves the efficiency of platform construction
