摘要： A subsea well control system comprises: a well tree (6 or 7) having a subsea control module (10 or 11); and a power and communications distribution module (5) for communication with the subsea control module via a communication link (8 or 9) between the subsea control module and the distribution module. The link comprises a 4-wire dual twisted copper pair as part of an RS422-based interface.
