The vessels are designed with good stability and seagoing characteristics. We work closely with our clients to allocate the right vessel at the right time at the desired location. The Vanguard is our latest state-of-the-art semi-submersible heavy transport vessel. Due to her ‘bowless’ design she can accommodate overhang on both bow and stern and has a deadweight capacity of 117,000 tons. With 11 vessels in operation, Boskalis is the global heavy marine transport leader.
