Abstract
A subsea system for oil or gas production and water injection operates without divers' assistance and with guide-cables and includes a template (50) equipped with ten drilling mouths (53) arranged in two rows of five. Each drill mouth (53) has a guidepipe (54). The upper extremity of the guide-pipe presents an external section for locking purposes. A guide-base (55) is provided with four posts (56) removable by a ROV. A central space is provided in the template for the setting of a manifold (60) through four posts (63) to guide the installation and devices which ensure the final positioning of the manifold (6) within established tolerances. Bases of export-line terminals (64) are located in one of the extremities of the template (50) Each base (64) is provided with two guide-posts removable by a 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) lock the export-line terminals. Analogous bases are located in the other extremity of the template for the control umbilical units. Pile-guides (69) are arranged in each one of the four vertices of the structure (68) of the template. A manifold (60) including a base-structure (70) where the pipes, the hydraulic and electric control lines, the terminal (73) for connection to the WCTs (74) and to the MSTs (75) and terminals (76, 77) for connection to the export-lines and to the hydraulic and electric umbilical units, as well as to the WCTs (74) MSTs (75) and their control system are attached.
