초록

Apparatus and method are provided for connecting electrical power for heating subsea pipelines after the pipeline is deployed. Electrical connections may be made subsea using wet-mateable connectors. The electrical power may be supplied from a boat or may be supplied from a host structure. A Remotely Operated Vehicle may be used to make the subsea electrical connections. Single Heated Insulated Pipes, Pipe-in-Pipe, heat tracing and other configurations for heating may be employed. The deployment of cables and other equipment for heating may be delayed un...
