The scope of work included project management, fabrication and installation of 8in steel catenary risers and 40mi (64km) of 8in and 12in pipe-in-pipe for the Big Bend and Dantzler field development projects in 7000ft (2100m) of water depth. It also included the design, fabrication and installation of eight subsea structures weighing up to 100-tonne each. All project management activities were performed at EMAS’ office in Houston, with pipeline production and structures fabrication at the EMAS Marine Base in Ingleside, Texas.
Since May 2015, Lewek Constellation has conducted more than 30 heavy lifts between 900-2200-tonne transferring rigid pipe reels, many of them in open water locations, for the Big Bend and Dantzler projects. This game-changing technology of multiple, transportable reels combined with heavy lift capability reduces the transit time and eliminates the need for direct spooling by the installation vessel, keeping the vessel in pipe-lay mode throughout the entire project. This effectively decouples Lewek Constellation from the spool base and takes the pipeline fabrication off the critical path.
Lewek Constellation and Lewek Connector are now mobilized to lay the pipeline and umbilicals on the Noble Energy-operated Gunflint development project.
