Chinese offshore vessel specialist CTW Offshore Engineering has ordered another four liftboats at China Merchants Heavy Industry (CMHI), eyeing more employment in the Middle East.

The four vessels, with hull numbers CMHI-277-03, CMHI-277-04, CMHI-277-5 and CMHI-277-06, will each be 92 metres long, 40 metres wide and 6.1 metres high.

The liftboats will be equipped to operate in water depths of 62 metres. They will have DP-2 dynamic positioning systems and are each able to accommodate 150 people.

To be built at CMHI’s facility in Haimen city in eastern China’s Jiangsu province, the vessels will provide service to offshore oil and gas fields in the Middle East, CMHI said, without saying if these are speculative newbuildings or whether they have charter agreements.
