Lankoforce Provides Riser Tethers for Layang Field in Malaysia

  • Operations & Maintenance

Offshore mooring rope specialist, Lankhorst Euronete Portugal, has supplied Lankoforce synthetic riser tethers to Dialog for the Layang field development in Malaysia.

The three riser tethers use Dyneema DM 20, a high modulus polyethylene (HMPE) rope, for permanent subsea anchoring of flexible risers and flowlines.

Each of the Layang development riser tethers is a single leg connecting a hold-down riser clamp with a tether anchor. They will tether two production risers and flowlines, and a gas export riser and flowline connected to an FPSO, the company explained.

The riser tether has a Lankoforce rope construction with a 12-strand braided rope core made from Dyneema DM20. The entire rope core is protected by a braided polyester jacket and polyurethane coating and includes ROV handling points for ease of installation and spliced eyes at each end.

The Layang field, operated by JX Nippon Oil & Gas Exploration, is located in Block SK10, offshore Sarawak, Malaysia, at a water depth of approximately 90m.
