Project Summary

In November 2005, the 2,500 t D1-Well Cum Water Injection Platform (D1-WWIP) jacket was launched offshore India in the Mumbai

High field. The steel jacket was fabricated in Teluk Ramunia, Malaysia, and was towed to India on the 348 x 100 x 22 ft launch barge

SWIBR CONQUEST. All engineering documents related to the jacket launch were reviewed and critical assumptions verified using

independent calculations.

The project scope included:

A short video shows the actual launch of the jacket offshore India. Requires Windows Media Player.
