Heavylift / Breakbulk
Fleet increase for anniversary
The maritime enterprise Jumbo, which is based in the Netherlands, specialises in offshore projects. It is set to expand its fleet by a new heavylift vessel with two cranes on board, with the unit due to be delivered in the first quarter of 2020. The subsea cranes, from Huisman Equipment, can be used at depths of up to 3,000 m and move loads of up to 2,500 t.
Transporting heavy equipment over the seven seas and simultaneously installing it on offshore facilities in the wind and weather with centimetre precision – that is the Jumbo’s expert business. The Dutch company requires reliable equipment for its complex projects and is thus making a huge new investment in its fleet for its 50th anniversary. The enterprise, having already announced the purchase of a new heavylift vessel at the end of 2017, has now clarified in detail what it will consist of. Huisman Equipment was asked to make two subsea offshore mast cranes that can be used variably.
Crane can reach depths of 3,000 m
The main subsea crane can lift weights of up to 2,500 t and is also fitted with lifting up masts. An active heave compensation system ensures that the movements of the waves are balanced out, providing better control of the positioning of a load relative to the seabed. The second crane can move up to 400 t and is also equipped for underwater tasks. The crane is positioned in such way that it can operate through a moon pool at depths of up to 3,000 m under water. This allows Jumbo to offer services that are not possible with today’s usual cranes.
The feature is also something that pleases Jumbo managing director Michael Kahn. “The new vessel equipped with these cranes will represent a milestone for Jumbo, allowing us to considerably improve our offerings in the offshore market.” The vessel, which is scheduled to become operational in the first quarter of 2020, is being developed by the company Ulstein Design und Solutions.
In addition to using traditional fuels, the vessel’s engines can also be operated with liquefied gas. The hull has Ulstein’s typical x-bow shape. It offers lower flow resistance and higher speeds, particularly in heavy seas. With its overall length of 185 m and its width of 36 m Jumbo’s new vessel will be the biggest of its kind with an x-bow.
