Helix successfully completed installation of two 86-ton pipeline-end-termination (PLET) modules as a prelude to the initiation of production of Murphy Oil Co.’s Thunder Hawk development in the deepwater Gulf of Mexico.
The project marked the first time Helix had installed PLETs of this dimension in 6,000-plus water depth using a single-line crane. The units were installed from the 380-ft Helix Intrepid reeled pipelay vessel, which has 400-ton crane capacity and a 10,000-ft water depth capability.
