Installation topside
and living quarters,
Thien Ung BK-TNG

For the Vietsovpetro Thien Ung project, Boskalis has installed the Thien Ung BK-TNG 4,200 metric tonne (mt) topside and 850 mt living quarter by offshore heavy lifting with the sheerleg Asian Hercules III. It was the world’s heaviest lift installation of a topside by a sheerleg in an offshore environment to date. 

Boskalis successfully executed the lifting of the 4,200 mt Thien Ung topside followed by a 850 mt living quarters. The topside and living quarters were installed on a (preinstalled) jacket in the Nam Con Son Basin, at a water depth of 120 meters. The topside lift, which is the heaviest offshore lift by a sheerleg was successfully completed on 21 September 2016 and the living quarters on 24 September 2016. The project was performed by the Asian Hercules III which is a 5,000 mt sheerleg operated by Asian Lift, a joint venture company between Boskalis and Keppel.

Scope

  • Installation engineering, comprising of lifting analysis, rigging design, mooring analysis
  • Preparation and mobilization of Asian Hercules III
  • Anchor pattern set-up and interface with transport barges
  • Lift and install of 4,200 mt topside and 850 mt living quarters
  • Demobilization of Asian Hercules III and reinstatement


Project challenges

It is the first offshore project for Asian Hercules III. The project was also executed in an extremely fast track manner to avoid the offshore installation period slipping into the monsoon months.


NINA

The project was executed without incident. The NINA initiative was not only inculcated within the Boskalis PMT and Asian Lift but also with WL Management and Vietsovpetro.


Conclusion

The success of the project was due to the strong cooperation between all parties. In spite of the short preparation and execution time, a strong focus on engineering, safety and sound operational excellence ensured the timely completion of this project.
