SemStar5-R™ is a free-standing subsea data hub package, designed for installation on subsea trees, manifolds, and process facilities.
The unit is deployed and retrieved by ROV, with connections to the subsea control and instrumentation system made with wet-mateable ROV-deployed jumpers - using either electrical or fibre-optic connections.
The external package is fully marinized for long-term subsea immersion, and the internal data hub multiplexing unit is an application-specific configuration of the innovative VetcoGray SemStar5™ subsea electronics module.
Flexible Communications. The SemStar5 uses an internal ethernet data bus supporting TCP/IP with flexible subsea communications options.
