发明名称 TREE PROTECTION SYSTEM
摘要 A subsea wellhead assembly having a net that protects the wellhead assembly from impacts with falling objects. The net can be deployed from a vessel onto a wellhead on the seafloor, or mounted onto a wellhead component above the sea surface and lowered with the wellhead component. The net can be retractable, so that an ROV can access the wellhead assembly by temporarily moving the net into a retracted configuration, then redeploying the net when finished accessing the wellhead assembly.
