Hallin Marine

Halllin deployed DP2 SOV Windermere with built-in saturation and air diving system to perform inspection of jack-up rigs. The underwater work included HPWJ and grit blasting to remove marine growth and miscellaneous repair work was also carried out.  

Prospect completed the detailed design of a submerged buoyancy collector (SBC). Prospect developed a working structure and provided a marine dynamic operational analysis of the SBC, confirming the stability and buoyancy when fully laden and when empty.

Hallin provides a DP2 Subsea Operations Vessel “Ullswater” c/w 15 man saturation diving system, air diving system, 100HP “CROV‐05” Workclass ROV, survey and USBL equipment to support Subsea Spool Tie‐in work, including flange protector installation and riser supports removal.  

SOV Carlisle, along with two CROV’s was deployed as command vessel for the installation of the Gravity-Based Structure located offshore Sakhalin island on the east coast of Russia.

In Bawal Field, Natuna Sea, Indonesia, Hallin developed a 40km, 14” pipeline from Hangtuah to Bawal. The work scope also included freespan correction and a survey of an ROV as built. The project began in April 2012 and finished in May 2012, using the DP2 Vessel Kendal and Work Class ROV (CROV) services.
