Swedish company Trelleborg’s offshore operation has won a substantial contract to supply equipment for CNOOC Ltd's deep-water Lingshui 17-2 gas field development off China.

Trelleborg will supply 18 kilometres of Tri-Strakes (vortex induced vibration strakes) for the risers and flowlines for the Lingshui 17-2 project.

This will represent one of the largest Tri-Stakes projects the offshore operation has been involved with.

The strakes will be placed on various sizes of pipelines attached to semi-submersible floating platforms and are suitable for both J-Lay and S-Lay scenarios.
