52 Maritime Reporter & Engineering News • MAY 2014 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. www.mammoet.com 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. www.rolls-royce.com World’s Biggest Crawler Crane Installs Legs on Ship ALP Tugs Get Rolls- Royce Deck Equipment MR #5 (50-58).indd 52 4/30/2014 3:40:32 PM
