能具体说说是哪里的gap吗?diverter 下面会连接ball joint 或flex jont,是类似法兰连接,怎会和diverter housing 碰撞。
ok.when the driliing riser deployment and retrieval,the riser is support by hook,and it is necessary to avoid the contact between the riser and the diverter housing under extreme ENV.So,i think the gap may be the diameter of the gap housing. |
