Robert Kuok's PaxOcean yard group has won three newbuilding contracts from Dutch shipbuilder Royal IHC.
It will build a 2,300-cbm trailing suction hopper dredger (TSHD) and two 3,500-cbm split hoppers at its plant in Indonesia.
They are expected to be delivered early in 2020.
The TSHD features a shallow draught which can be deployed worldwide.
The two split barges, based on the IHC standard split trail 3,500 design, are very practical in use in combination with backhoe, hopper and cutter suction dredgers, it said.
"This new contract represents a milestone in strengthening the confidence of Dutch companies in PaxOcean’s ability to deliver quality and cost effective solutions," PaxOcean added.
The group owns and operates six shipyards in Singapore, China and Indonesia.
