SNEEK, the NetherlandsLankhorst Euronete Portugal has supplied three Lankoforce synthetic riser tethers to Malaysian group Dialog for JX Nippon’s Layang field development in block SK10 offshore Sarawak.

Water depth is around 90 m (295 ft).

Lankoforce tethers are designed to hold risers and flowlines in position, connected to subsea production systems such as manifolds, wellheads, christmas trees, and well jumpers.

Each comprises a single leg connecting a hold-down riser clamp with a tether anchor. The systems will tether two production risers and flowlines, and a gas export riser and flowline connected to a FPSO.

The riser tether has a Lankoforce rope construction with a 12-strand braided rope core made from Dyneema DM20 high-modulus polyethylene rope, which provides the required strength and mechanical performance.

The entire rope core is protected by a braided polyester jacket and polyurethane coating and includes ROV handling points and spliced eyes at each end.
