China’s privately-owned Sinopacific Shipbuilding Group has won its first order from the Southeast Asian market to build four OSVs for Singapore’s Vallianz Holdings.

The AHTS vessels, based on Sinopacific’s inhouse design SPA60, will be built at Zhejiang Shipyard and deliveries are expected from the end of 2014 to the start of 2015. Financial details of the deal were not disclosed.

“This partnership (with Vallianz) is aligned with our strategy and I’m convinced that this will showcase the advantages of our product in the global market, boosted by this confidence of Vallianz and will further guarantee Sinopacific’s leading position in the OSV market segment,” said Simon Liang, chairman and ceo of Sinopacific.

Vallianz has a current fleet size of 29 young and modern OSVs and serves the Middle East, Latin America and Asia Pacific markets.

Last week, Sinopacific clinched its first domestic order to construct five OSVs for Shenzhen Huawei Offshore Shipping Transport.

At the end of June 2014, Sinopacific has delivered more than 160 OSVs.
