Malaysia Marine and Heavy Engineering Sdn Bhd (MMHE) delivered an offshore structure to Woodside Energy Limited, Australia. The Angel Gas topside sailed away from MMHE on 22 March 2008 and has been installed at the Rankin Field, offshore North West Australia.

This project recorded a new challenge for MMHE when for the first time a topside structure weighing 8,300 metric ton was jacked up 25 meters high to enable the insertion of the 800 MT deck support frame below the topside. Other fabrication companies have executed similar task but the structures were raised only up to 12 metres height. The jacking up of the topsides up to 25 metres in height requires stringent monitoring and precision movement. It took two days for the project team to successfully and safely complete the mammoth task. The project team inserted the deck support frame by using self propelled mobile transporter.

The deck support frame is designed to support the topside during installation, through the float over mechanisms. The Angel Gas topside is equipped with a helideck, three storey temporary living quarters (which consist of electrical room, instrument room, 12 accommodation rooms), temporary accommodation facilities, platform crane, flare boom, four coolers and pressure vessels.

The offshore installation for the topside was a 'float-over' method, where the deck support frame shall be left on the transportation vessel, once the topside has been securely installed on the jacket.

MMHE was awarded the contract for fabrication engineering, procurement, construction, load out, sea fastening and commissioning of the Angel Gas Project topsides in March 2006. The project recorded 3.3 million man-hours worked without any Loss Time Incident.
