Abstract (en)
[origin: WO8803596A1] A system for the control of subsea extraction of a liquid or gaseous hydrocarbon product from a well head on the sea bed in which the product is extracted under the control of valve systems contained in a christmas tree (3) located over and secured to the well head and is then fed via a pipeline to a remote terminal. The christmas tree is controlled and monitored by a control module package (10) which forms the end termination to an umbilical U4 supplying power from and transmitting signals to and from said remote terminal. The control module package (10) is physically connected to the christmas tree (3) underwater by engaging the complementary end terminations (12) and (13) and forms the sole power and signal path connection between the christmas tree and the remote terminal. Guide means (15, 16) and optical or acoustic sensors (17) may be provided to assist in aligning the terminations (12) and (13) during their interconnection.
