Background
The seabed oil and gas pipeline is the national lifeline project, and whether the seabed oil and gas pipeline is safe or not has great relation to the development of marine oil and national economy in China. However, the marine environment conditions are complex and various, the submarine pipeline bears complex loads and environmental conditions such as dead weight, external hydrostatic pressure, internal pressure, rugged seabed, seawater corrosion and the like, and the pipeline laid on the seabed is very likely to be damaged by ship falling objects, offshore drilling platform falling objects and other offshore structure falling objects during navigation, so that extremely serious oil and gas leakage accidents can be caused, and huge economic, social, political and ecological losses can be caused to the country.
One important consideration in marine structure safety is the falling load generated during the lifting of a crane or other similar device. In ocean engineering, when a crane performs a lifting operation, a lifted object may fall at any position within the reach of the crane. Falling object events occur quite frequently as an accidental load. For example, the number of pipe drops in drilling operations is as high as 1/5 for the total number of unit platform hoisting operations per year. Other items, such as containers for food, tanks, winches, mud pumps, etc., may also fall off during the lifting operation. The main risk consequence of objects falling into the sea is damage to the subsea pipelines and underwater equipment. When subsea pipelines or subsea equipment contain hydrocarbons, any minor rupture thereof can have catastrophic consequences.
