Vessel Monitoring and Collision Risk Management

Helping protect your assets

Passing and attendant vessels create a major accident hazard risk for offshore installations with potential consequences including loss of life, environmental damage, loss of production, and reputational damage. Leveraging on enhanced Radar Early Warning Systems (REWS) and other communications technology, tied back to a central control centre, we help you manage these risks as part of a robust collision risk management strategy.

Round the clock monitoring is provided 365 days a year by a team of experienced mariners providing a dedicated service for the protection of surface piercing and subsea assets. Our remote vessel monitoring service is not weather dependant and works via these three principles:

Detect potential collision risks automatically through fully configurable guard zones and virtual fences.

Assess collision risks using the latest software solutions and operating procedures to aid decision making.

Communicate reliably using remote VHF and Digital Selective Calling (DSC) to manage potential incidents.

Helping protect your assets

Technology in action

Services are provided using the latest technology, where automatic tracking of Radar and AIS provides real time situational awareness and control to monitor your offshore infrastructure. Robust system design and dedicated offshore support teams ensure that operational availability is maximised.
