The PSVs are among 16 vessels believed to be being bought by another of the shipping and offshore magnate’s web of companies, Oslo-listed owner Deep Sea Supply, broking sources earlier told Upstream.
Ulstein will deliver its PX105 design for the dozen vessels to be built at Sinopacific’s Zhejiang yard in Ningbo, China, in the first such contract award from Seatankers for the Norwegian ship designer.
The company will supply a total package including design, engineering and equipment under the contract, for which a value has not been disclosed.
It is also delivering the diesel-electric propulsion systems and electrical package for the 89-metre vessels that are able to reach speeds of 15.5 knots and are capable of maintaining high speed in harsh weather conditions.
Ulstein has now sold its PX105 design for 26 vessels, while Sinopacific has used its designs for 22 vessels built at the yard.
As well as taking all of the 12 PSVs on order at the Chinese yard, Deep Sea Supply was also reported to be preparing to buy an additional four PSV 05-design units believed to have been contracted by Seatankers at Sinopacific.
