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.
