Heavy lift world first for Boskalis vessel becomes drydock for Carnival Vista

In a world first Boskalis Westminster N.V. (Boskalis) has been awarded a contract by Carnival Cruise Line to lift cruise ship Carnival Vista out of the water onto the BOKA Vanguard and transport it to a shipyard facility for a drydocking operation.

The first of its kind operation will take place in the coming weeks in Freeport, Bahamas, said Boskalis.

The Carnival Vista is the second largest cruise ship in the Carnival fleet with a capacity of nearly 4,000 passengers and a length in excess of 300m. Due to technical issues with Carnival Vista’s azipods, the ship’s main propulsion system, the vessel must be repaired in a dry dock which is currently not available in the region.

Boskalis is offering a unique solution to facilitate this dry dock repair by deploying the world’s largest semi-submersible heavy lift vessel BOKA Vanguard.

Carnival Vista will be loaded onto the BOKA Vanguard off the coast of Freeport, Bahamas. This loading and lifting operation is planned to take place between 12 and 14 July.

The BOKA Vanguard will then transport Carnival Vista to a nearby shipyard facility where the repairs will take place whilst the cruise ship is resting on the BOKA Vanguard. Upon completion of the repairs, Carnival Vista will be offloaded in time for its next cruise voyage later this month.

The BOKA Vanguard is the world’s largest semi-submersible ship uniquely positioned to lift and transport extremely heavy cargoes in a dry and safe manner.

The vessel has an impressive track record transporting large offshore oil and gas structures, but can also carry other vessels and act as a floating offshore dry dock facility. The BOKA Vanguard is unique in that is has an open and flat stern and bow-less deck measuring 275m by 70m allowing the vessel to lift and transport cargo’s longer and wider than these deck dimensions. By filling its ballast tanks, the ship deck is submerged in a controlled manner, allowing it to lift deep draught cargoes.

This creates an alternative for drydocking allowing inspections and repairs to be safely and efficiently conducted at a location where traditional drydock alternatives are not available.
