Kikeh Shock Absorbers Render

Antares Enery Solutions were contracted by MISC Berhad Ltd to provide Engineering design and consultancy services to provide a solution to minimise impact schock loading during a heavy lift operation on the Kikeh FPSO. Antares Energy Solutions developed a damping/soft landing system for the Kikeh FPSO Heavy Lift Project, located 120km north-west of Labuan, Malaysia.

Antares Energy Solutions undertook the fast track from Conceptional design, manufacture and testing of a soft landing system that would accommodate any shock/impact loads during the installation of the 150Te accommodation module onto the FPSO Navigation bridge roof, whilst it remained on station.

The cylinders were pre-charged with compressed air and fully extended, as the load was applied the cylinder.Kikeh Shock Absorbers The cylinders were then further compressed as load was landed and the absorption from the shock loads taken in the cylinders.

A total of six cylinders were manufactured and utilised for the project specific lifting operation during which they performed faultlessly. In addition Antares prepared an Operations Manual and a full As Built Dossier. The entire project was completed within a six week period.

Seagull AntaresThe first project for detail design and fabrication of 3 No Net Guard structures for FMC Technologies is now complete. The structures were designed to meet all industry standards for wellhead protection and overtrawlability. The structures were fabricated by Seagull Antares at the Tonoto yard in Tuas, Singapore for load out directly onto the transportation barge.

 

Completed and Current Projects

Antares Energy Solutions Pte Ltd has completed three projects this autumn two with Hallin Marine in Indonesia and one as client representatives for Thanglong in Vietnam. We are currently working on Banyu Urip project for Rekayasa Industi.

Jangkar Umbilical Replacement, Client Hallin Marine

AES were engaged by Hallin Marine to provide Project Management, Installation Engineering and Procurement Support for the installation of 6.2km of hydraulic umbilical for their contract with PT Timas Suplindo.

Jangkar Umbilical ReplacementThe old umbilical was disconnected and wet stored to one side and the new lay route surveyed. Concrete mattresses were placed at the crossing locations. The new free issue 88mm Dia, hydraulic control umbilical was pulled into the KH platform and successfully laid away and stabbed into Jangkar subsea wellhead. Successful tests were completed on the well by Star Energy and production restarted.

 

PCP-PF Power Cable Installation, Client Hallin Marine

Hallin Marine engaged AES to undertake Project Management, Offshore Engineering Support and Procurement Support for their installation contract with PHE.

Power Cable InstallationSOV Ullswater surveyed the new lay route and the pull-in of the cable onto PCP platform, via the preinstalled I-tube, then proceeded. The lay away to PF platform commenced, including the installation of Uraduct for the pipeline crossings. The cable was laid in a lazy ‘S’ configuration in front of PF platform. After the successful pull-in at PF platform, the cable was then successfully tested by PHE and was found to be fully functional.
