Need to pick up something extraordinarily heavy while floating in the middle of the ocean and then placing it somewhere with extreme precision?

There are a number of large, semi-submersible crane barges on the high seas these days, such as the Thialf or the Saipem 7000, which have accomplished impressive offshore installation jobs, however Dutch contractor Heerema is looking to build a new vessel for extreme heavy lift jobs of the future, one that is capable of doing a combined lift of 20,000 metric tons.

This is 5,800 metric tons more than what the Heerema’s Thialf is rated for.

Huisman reports that they have received a Letter of Intent to deliver two 10,000 metric ton-capacity, tub-mounted cranes for this new vessel. The Dutch crane specialist notes that these two cranes will feature a 2,500mt aux hoist and a whip hoist with a maximum reach of 155m. The main hoist, in a reduced reeving, can lift 1,000mt to 1,000m water depth and will feature active heave compensation.

The final investment decision to build this new semi-submersible crane vessel will be made by Heerema before the end of 2014.
