Sarens helps load out 11,200-ton Jerun A jacket
Malaysia Marine and Heavy Engineering recently hired the heavy lift engineering specialist, Sarens, to help out with the load-out of heavy modules for the EPCIC SK408W Jerun field development project. The load-out was completed at the Malaysia Marine and Heavy Engineering west yard in Johor, Malaysia.
Sarens said the challenge during the operation was the tide restriction which considerably reduced the operation window. The company was also tasked with providing the full contingency for the skidding equipment and ballast systems. Detailed planning and precise engineering calculations were done by the team prior to the execution to minimise the risk and meet the timeline.
Additionally, Sarens proposed backup systems for contingency. The teams also installed the secondary strand jack at Dead Man Anchor other than the usual anchor block to ensure that we meet the timeline before the tide comes down.
For the project, Sarens deployed eight Strand jacks with a capacity of 588 tons, 44 submersible, four 800-ton breakout jacks and a set of ballast. tide, barge monitoring and ballast tank sounding.
The equipment was swiftly moved from Vietnam to complete the time-sensitive project. Project Manager, Ridzuan Jamiran stated, “As a result of good coordination within each department, the equipment arrived at the MMHE yard in 10 days.” He adds, “Within next 10 days, Sarens installed eight strand jacks and 44 submersible pumps, functionally tested all the equipment, and was ready for the operation two days ahead of schedule.”
Considering the 300-metre distance from the current to the final position, the Jerun A jacket, weighing 11,209 tons, was safely and successfully, skidded, and loaded out within the designated timeline.
