Abstract

The invention relates to an offshore self-elevating work platform, in particular to a self-elevating platform pile leg. The self-elevating platform pile leg comprises a plurality of detachable pile legs which are integrally connected through flanges. The self-elevating platform pile leg has the advantages that a function of the self-elevating platform for adjusting the length of the pile leg according to own operation is realized, safety and reliability of platform operation for platform towing or shallow-water operation are improved, cost is saved, similar pile legs which are detached can be shared by different platforms, utilization rate of the detachable pile legs are increased, and cost is reduced.

Description

technical field [0001] The invention relates to an offshore self-elevating operation platform, in particular to a self-elevating platform pile leg and an installation method thereof. Background technique [0002] Jack-up platform is a kind of offshore operation engineering equipment, which is widely used in various aspects such as offshore oil and gas drilling, offshore piling, offshore lifting, and personnel living. It consists of hull, legs, lifting mechanism and a series of equipment. As an important component of the jack-up offshore platform, the pile legs are mainly used to support the platform's offshore operations and transfer the load on the platform to the seabed foundation. The safety of the pile leg structure is directly related to the safety of the whole platform. [0003] The forms of pile legs can be divided into shell type and truss type. Among them, shell type pile legs have round, square and polygonal shapes, and are composed of the main body of the pile l...
