Lifting operation plays an important role in the structure assembly and offshore installation of offshore oil platform. Once an accident causes structural damage or operation failure

it will cause serious loss of life and property. Although the hanging point is the auxiliary structure of lifting operation

it needs to bear the self-weight of the lifting structure and other additional loads. Therefore

in order to ensure the safety of offshore oil platform lifting

it is necessary to consider the welding quality of hanging points. Combining with management experience in many offshore oil platform engineering projects in resent years

the typical form of offshore oil platform is introduced

and the welding construction technique of hanging points in offshore oil platform is analyzed form the aspects of common steel and weldability

welding technology design and welding construction measures.
