OFFSHORE (PT 1) Ӏ SECTOR SNAPSHOT
three turbines at the port, working in weather conditions where wind speeds can reach 10m/s. Mammoet joined the project in the planning phase, advising on crane selection and logistics for moving components arriving from The Netherlands and For-sur-Mer. To reduce the impact of wind
delays all turbine components were delivered to the port before assembly began. A large lattice boom crawler
crane, a CC8800-1, was used for the main lifts, while two 200t mobile cranes assisted to carry out tailing operations. The heaviest item was the 380t nacelle. The project team reinforced a
40m area of the quay to withstand loads of up to 30t/m, using layers of wooden mats over gravel to
prepare the ground. Mammoet deployed 24 lines of self-propelled modular transporters (SPMTs) to transfer the turbine parts across the port, from the quayside to dedicated laydown areas and onwards for assembly.

LIFT AND SHIFT They say ‘necessity is the mother of invention’ and to help make the movement of increasingly large monopiles faster and more cost-effective Mammoet is not just developing new methods it’s creating new hardware, too. At the end of 2025 it publicised a new XXL monopile lifting and transport system comprising an upgraded terminal crane (MTC) that can lift mega monopiles into the water for offshore feedering, and a specialist patented jacking- and-cradle system for their safe handling, using SPMTs.
Mammoet used the equipment
at the port of Ronne, Denmark, where 21 monopiles were offloaded, stored, capped and then lifted into the water. No civil work was needed to reinforce the quay (which would have been required if a crawler crane had been used). The marshalling was for the 315MW Windanker offshore wind farm, which was being fed by Rotterdam, Netherlands-headquartered global marine contractor Van Oord in the German waters of the Baltic Sea.
The monopiles arrived at the
port of Ronne from Spain, the heaviest weighing 2,150 tonnes and measuring approximately 87 metres in length, with a diameter of ten metres.
Fitted with Mammoet’s XXL monopile transport system, 90 axle lines of SPMT lifted them off their grillages and cradled them securely as they were driven off the vessel. They were then taken to a temporary storage location and placed onto sand bunds, ready to be called off for capping to make them watertight. The added stroke of the XXL monopile transport system allowed the monopiles to be lifted higher so that the indents of the storage bunds could be deeper, improving their support while using fewer materials. At the capping location a
LR1750 crawler crane installed plugs onto the top and bottom ends of each monopile. Then the monopiles were driven to the quayside in front of the two MTC1600 cranes, which Mammoet developed specifically to lift XXL monopiles onto vessels and into
