wheatstone topsides float-over makes chevron history

May 6, 2015 – The Wheatstone Project recently made Chevron history with the largest single, integrated topsides float-over installation the company has ever completed. The platform topsides were installed onto the awaiting steel-gravity structure located 140 miles (225 km) offshore the Ashburton North plant site.

"This is a significant achievement and milestone for the Wheatstone team," said Roy Krzywosinski, managing director, Chevron Australia. "It is the culmination of years of planning and collaborative execution by Chevron and our various contractors."

The 37,000-metric-ton topsides structure was built in a South Korea shipyard and traveled via transport barge 4,067 miles (6,546 km) to the waters of Western Australia where it was successfully floated over and set onto the steel gravity structure. The full Wheatstone platform measures 738 feet (225 meters) tall from the base of the steel gravity structure to the top of the flare boom and is designed to withstand 12-story-high waves.

Over the next six months, Chevron Australia and its contractors will undertake hook-up and commissioning activities as the Wheatstone Project continues toward first gas in late 2016.
