Singapore's Calm Ocean Building 2 Heavy-Lift Semisubs in China

Singapore-based Calm Oceans Pte Ltd. reported Monday that Brian Chang, the owner of the compan, has begun developing 2 Heavy-Lift Semisubmersibles suitable for the construction and the decommissioning of offshore platforms. Each vessel is designed to lift 7,500 metric tons with two cranes onboard. The construction period will be 30 months.

Brian Chang has built the largest shipyard crane in the world and tested at 25,000 metric tons. The largest shipyard crane, named the “Taisun”, was designed in cooperation with Huisman Equipment B.V. and was built by Yantai Raffles Shipyard. It had been used to lift the deck boxes of many large semisubmersible drilling-rigs and held the record of most lifts between 14,000 metric tons to 18,000 metric tons.

Brian Chang was the founder and owner of Yantai Raffles Shipyard then until the Shipyard was sold some four years ago to CIMC of China. Meanwhile, Brian Chang, through Calm Oceans, has pioneered the patented MCP (Mono Column Platform) Self Installing and Self Removable Offshore Platform for the offshore oil and gas industry. The MCP, suitable for 500 feet water depth, is being built at Blue Island Shipyard in China.
