EDINBURGH, UK – T12 has been working with Aberdeen-based Sentinel Subsea on the latter’s subsea monitoring system, WellSentinel.
The system, which applies to subsea wells, wellheads and subsea Christmas tree networks, identifies loss of containment incidents and transmits an alert signal via satellite.
It is intended as an alternative to active power, routine system checks or an umbilical connection to the surface, and is also said to allow asset owners to comply with inspection requirements without the need for vessel-based manual operations.
A front-end engineering design study led to T12 developing an overtrawlable capture canopy concept that should protect the system from potential damage during shallow-water deployments.
The canopy solution can also be integrated into existing subsea infrastructure to provide effective levels of overtrawlability and impact resistance, T12 added.
