The TRIYARDS Holdings built Lewek Constellation ice-class DP3 multi-lay vessel, was named Support Vessel of the Year at the 2016 Offshore Support Journal (OSJ) Awards.
Only offshore support vessels (OSVs) deemed to have raised the bar through innovative design and ultra-efficient operation are able to earn their owners, designers and builders the coveted title in this category. This year, just three other vessels were shortlisted.
A subsea construction vessel with ultra deepwater pipelaying and heavy lift capabilities, the Lewek Constellation is an asset that is capable of undertaking diverse work scopes. Designed to handle both rigid and nonrigid pipelines, she boasts an 800-tonne Huisman multi-lay system and a 3000-tonne Huisman offshore mast crane (installed in Europe and China respectively), as well as two Schilling HD work-class remotely operated vehicles. Moreover, her portable reel system makes her suitable for remote fields, reducing turnarounds by allowing her to carry out offshore reel transfers without having to return to the spool base.
Built by TRIYARDS at its shipyards in Vietnam, the vessel secured a contract to extend the Etame Marin offshore field in Gabon, West Africa, before construction was finished. Successfully completed in October 2014 despite tight deadlines, the US$120 million project for VAALCO Gabon (Etame) covered the full spectrum of field installation.
After being fitted with a multi-lay tower and ancillary equipment in the Netherlands, the Lewek Constellation departed in March 2015 for the Gulf of Mexico, where she completed three subsea tie-back projects for Noble Energy. She proved her operational capabilities at the Big Bend and Dantzler field development projects by installing a pipe-in-pipe (PIP) system, working at water depths of 2100m.
She also successfully completed more than 30 heavy reel lift transfers, many in open-water locations. The technology used by TRIYARDS reduced transit time and eliminated the need for direct spooling, keeping the vessel in pipelay mode throughout the project. Capping these achievements, the Lewek Constellation successfully laid a test pipe at a tension of 632mT.
She is currently being deployed at Noble Energy’s Gunflint development project to lay pipelines and umbilicals. Afterwards, she will head for Australia, where Apache Energy will employ her in a $105 million project at the Julimar offshore development field.
