Location optimization method for drilling platform;

Calculation method of rig hook load on deepwater drilling platform

The key points in exploration and development of offshore marginal oilfields are: to develop advanced exploration technologies like 3D seismic,drilling platform for offshore recovery,pipelaying for oil and gas transportation,and to pay attention to environment protec.

Diesel generators are very important equipments on drilling rig.

There are many ottshore rig running on China sea.

A comparison is made between ships and offshore drilling platform.

The offshore drilling platform jacking gear is divided into two parts——the electric driving and the hydraulic actuation.

Based on the characteristic of industry of Offshore Drilling Platform, this paper studies the the nesting problem and incising problem of the two-dimensional irregular parts, builds a system frame for the automatic nesting and numerical control programming ,and does a deep research about the nesting problem of the two-dimensional irregular parts, finishes the part of automatic nesting.

As a mobile ocean platform,and owing to its high positioning capacity and good operation stability,the self-elevation drilling platform takes a leading role in continetial shelf exploration.

As the maritime moving platform, the self-elevation drilling platform is the main force in the exploration of the continental shelf as the result of good fixing and reliable working.
