4Subsea has received a contract to deliver integrity monitor systems for six flexible risers on Statoil’s semi-submersible platform Snorre B in the North Sea.

The company was awarded this new contract after delivering the fifth system for Snorre A platform. Its monitoring system has been designed to improve security and reduce the chances of production downtime or riser failure.

4Subsea also claimed that this system does not require manual inspection, decreasing operational costs. Furthermore, the solution simplifies daily inspections of the risers.

4Subsea CEO Peter Jenkins said: “We are pleased that Statoil continuously trusts us to play an important role in maintaining secure and cost-efficient production at their installations through the integrity management work we perform on flexible risers and flowlines.”

The monitoring system works with 4Subsea’s AMOS solution that evaluates the condition, integrity and expected service-life of the flexible risers. AMOS also analyses the riser annulus diffusion rate, detecting early signs of riser failure.

"The monitoring system works with 4Subsea’s AMOS solution that evaluates the condition, integrity and expected service-life of the flexible risers."

Under the contract, 4Subsea will provide upgraded systems that come with added functionality to measure condensation of liquid in the annulus vent gas. This functionality was developed by the company’s R&D department last year.

Statoil will implement an integrated system in control rooms at Snorre B. Installation of this solution enables remote-monitoring from land to provide quicker response times.

Siemens is the Statoil’s main provider of automation services for Snorre B field.

4Subsea will collaborate closely with Siemens to integrate the monitoring system with the existing infrastructure and fulfil operator requirements.
