E-Line Lifting Solution Offshore

Case Summary

TC15 Stiff Leg crane was recently deployed on an offshore platform in Malaysia where Thunder Cranes assisted with lifting & skidding in support of E-Line activities.

Our client required Thunder Cranes’ specialised lifting services as the existing platform crane had insufficient lifting capacity for loading and positioning the heaviest component of the E-Line equipment (4.5MT) from supply boat to the platform main deck.

In addition to lifting E-Line components, our crew assisted the well-intervention team in skidding and repositioning the E-Line equipment to multiple well-head locations during the project.

Timeline

Following a site visit, a detailed proposed rig up and lifting plan was produced by our engineering team in September 2020 to the satisfaction of the client, with the project scheduled to begin in December 2020.

TC15 modular crane was deployed to the remote platform via supply boat. Modular components of our crane were offloaded from the supply boat to the main platform deck with the assistance of the platform crane. The TC15 temporary installation crane was then rigged up and secured to the platform main deck structure via clamping (requiring no hot work).

Following the E-Line intervention work completion we assisted with backloading the E-Line equipment to the supply vessel. We then rigged down and back loaded TC15 to the supply vessel for the return trip onshore.

Outcome

By deploying the TC15 stiff leg crane the client benefited from a cost-effective lifting solution well-suited to the platform size and the needs of the E-Line contractor. Using alternatives, such as a lift vessel, would have been prohibitively costly especially in this case (stand-alone well intervention project). The project was completed in a timely manner, safely and successfully.
