COMPLEX FEED TYPE SUBSEA PIPELINE

摘要

The present invention relates to a complex feed type seabed pipeline. Specifically, it is possible to reduce effort and a time required for dismantlement and installation by transferring a part or entire among crude oil, LNG, and electricity via a modularized pipeline to reduce the number of pipelines required for the installation. It is possible to reduce costs required for the manufacture and installation by the modularization of the pipelines and to reduce a space required for the installation of the same. The convenience of the repair and maintenance can be enhanced. The crude oil can be smoothly transferred by the viscosity of the crude oil using the heat generated due to the electrical transmission of electricity and the load of an oil supply pump can decrease. The complex feed type subbed pipeline according to the present invention is connected to a single point mooring (SPM) and a land base or a vessel and a floating offshore structure, and provides a pathway to allow the selection among the crude oil, LNG, and electricity to be respectively isolated and transferred.
