PRODUCT FEATURE: DECK MACHINERY
Mammoet employed the LR13000, re-
ported to be the biggest crawler crane in
the world, to install four platform legs on
Van Oord’s newest wind turbine installa-
tion vessel, Aeolus.
In 12 days the giant crane was as-
sembled at Lloyd Werft in Bremerhaven,
Germany. The fi rst of the four 87m long
steel platform legs, each weighing 920
tons, were settled into its jacking posi-
tion on the 139 x 38 m vessel. For the
job, Mammoet designed, fabricated and
delivered tailor-made top lifting tools
and a tailing frame to ensure that the
legs, that have no lifting points, can be
lifted securely. In addition to the plat-
form legs, Mammoet will also install
four spudcans, using a specially engi-
neered method. This method involves
placing the partly rigged spudcans on
the seabed, moving the Aeolus over it
and connecting the spudcan with the leg
with the use of cranes and divers.

Rolls-Royce won a $31.9m contract to
deliver deck machinery for four ocean
going tugs, designed by Ulstein Design
& Solutions, for Dutch company ALP
Maritime Services. The vessels will be
constructed in Japan by Niigata Ship-
building & Repair. The vessels are being
developed for towing large structures like
oil rigs and fl oating production units over
long distances. The bollard pull for each
of the four vessels will be 300 tons and
they will be equipped for anchor handling.
The deck machinery include a com-
plete low pressure winch solution and a
stern roller. The towing/anchor handling
winches are specially developed in coop-
eration with the ship designer and owner.
The supply of rudder and steering gear is
also included in the Rolls-Royce scope.
The Ulstein design SX157 vessel will
be delivered from Japan by Q1 2016.
