METHOD AND SYSTEM FOR CONTROLLING DEVICES IN HYDROCARBON PRODUCTION

摘要

A system for controlling the operation of devices (61, 62, 63) of a hydrocarbon production system has two reprogrammable central controllers (100) contained in a retrievable module (49a) of a seabed facility (20') associated with a hydrocarbon field (170). Local controllers are configured to control the operation of specific devices, such as actuators (61), sensors (62) and valves (63) within the module (49a) and within tree wellheads (30') of the field (170) and are locally connected to these devices (61, 62, 63). A single common data bus (130) links the central controllers (100) and the enables data to be transmitted in response to the central controllers (100) receiving signals.
