China’s Cosco Shipyard Group has landed a $120m deal converted from options to build four PSVs for a Singapore-based company.

The unnamed shipowner has also secured options for two additional similar offshore vessels to be built at Cosco (Gunagdong) Shipyard, a subsidiary of the state-owned Cosco Shipyard Group.

The PSVs are scheduled for delivery from the second quarter of 2016 to the first quarter of 2017.
