The Da Nang-based Song Thu Co laid
the keels for four 5,000 hp tugboats at a ceremony on Saturday.
The 24-metre long, 11-metre wide vessels, known as ASD (Azimuth stern driver) 2411, will be built by the State-owned company for the Netherlands
-based Damen group under a $18.75m contract signed last year.
The Dutch group will supply the design, technologies, and equipment for building the vessels. Colonel Ha Son Hai
, the company’s managing director, said the tugboats would be completed in 36 months.
He said this year Song Thu would also build a 3,500 hp rescue vessel for the coast guard, vessels to respond to oil spills, and multi-purpose vessels for use in the oil and gas sector.
