SUBSEA PRODUCTION SYSTEM

摘要

This invention refers to a subsea system for oil or gas production and water injection which operates without divers' assistance and with guidecables, said system consisting of a template (50) equipped with 10 drilling mouths (53) arranged in two rows of 5, each said drilling mouth (53) consisting of a guide-pipe (54), the upper extremity whereof presents an external section for locking purposes and a guide-base (55) provided with four posts (56) removable by ROV, a central space for the setting of a manifold (60) through four posts (63) to guide the installation and devices to ensure the final positioning of the manifold (6) within the established tolerances, bases (64) of the export-line (or delivery line) terminals located in one of the extremities of the template (50), each said base (64) being provided with two guide-posts removable by ROV, in addition to reaction posts (66) which orient the lowering of the pulling and connection tools and transfer the stresses to the structure of the template, receptacles (67) to lock the export or delivery line terminals, analogous bases located in the other extremity of the template for the control umbilical units, guides (69) for piles arranged in each one of the four vertices of the structure (68) of the template, and a manifold (60) including a base-structure (70) where are attached the pipes, the hydraulic and electric control lines, the terminals (73) for connection to the WCTs (74) and to the MSTs (75) and terminals (76, 77) for connection to the export or delivery lines and to the hydraulic and electric umbilical units, as well as to the WCTs (74), MSTs (75) and their control system.
