Shipyard begins building tugboats for Dutch firm

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 VND300 billion (US$18.75 million) contract signed last year.
