复杂海况下工程船的锚泊方案设计

Anchor Pattern Design for Derrick Barge in Congested Area

随着海上油气田的不断开发,海管和海缆等海底设施越来越多,海底情况更加复杂,工程船舶在复杂海况中的抛锚就位逐渐成为海上平台安装的最大风险点和难点。KJO油田是一个投产50多年的老油田,随着油田设施不断增加,该油田海底设施的密集程度超过任何一个国内油田。以"蓝疆号"在该油田中进行IWJ-6平台安装为例,介绍了锚泊的方案设计,可供以后类似工程借鉴和参考。

With the continuous development of offshore oilfield, subsea facilities such as pipelines and cables are increasing synchronously, the condition on seabed is too complex to hand anchor for derrick barge in these oil fields. Anchor handling becomes the highest hazard and most difficult step in offshore platform installation. KJO oil field locates at the neutral area between Saudi Arabia and Kuwait, where subsea pipelines and cables is far more congested than any oilfield in China with the continuous development in the past 50 years. Now the anchor pattern design for IWJ-6 platform installation performed by Lanjiang derrick barge in KJO oilfield is presented here for providing reference.
