4Subsea has secured a contract for delivery of integrity monitor systems for six flexible risers on Statoil’s semi-submersible platform Snorre B in the North Sea.
The company was awarded the contract shortly after the delivery of the fifth system in a row for Statoil’s Snorre A platform.
The monitoring solution improves security and reduces risk of production downtime or riser failure. At the same time, the installation will reduce operational costs, since the need for manual inspection is eliminated, 4Subsea explained.
Peter Jenkins, CEO of 4Subsea, 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 solution is based on 4Subsea’s Amos system, which analyses the condition, integrity and expected service life of the flexible risers.
Furthermore, the contract includes added functionality for measuring and trending condensation of liquid in the annulus vent gas.
4Subsea co-operates closely with Siemens, Statoil’s main provider of automation services on Snorre B, on integrating the monitoring system to existing infrastructure and to fit the totality of solutions deployed for the operator.
