SAL Heavy Lift has acquired a crane boom extension that increases the lifting height on its vessels
SAL Heavy Lift has acquired an easily reconfigurable crane boom extension that increases the lifting height on its vessels, enhancing their ability to undertake offshore wind and offshore oil and gas work.
The addition to the cranes for two of its vessels, known as a fly-jib, was purpose-designed for the company’s Type 183 vessels Lone and Svenja and is installed when required on the booms of the main cranes on the ships. Lone was the first vessel in the SAL fleet to be fitted with it.
The fly-jib raises the crane’s hook to a height of 70 m, which has already proved to be a significant advantage when working for clients in the offshore renewables market.
With greater lifting height and outreach, SAL’s new fly-jib will help the vessels lift lengthy components vertically, as is often required in the offshore wind industry when structures are being installed, a challenge SAL said it faced recently with a piling project.
SAL head of marine projects Sune Thorleifsson explained that a fly-jib had long been on the company’s ‘wish list.’ When a client approached it with a requirement to drive piles into the seabed for an offshore wind project that was the incentive it needed to acquire the equipment. “The piles were so long that it was not possible to upend them for installation without the fly-jib,” Mr Thorleifsson explained.
SAL Heavy Lift’s sister company SAL Engineering worked with manufacturer of the cranes on the vessels, TTS-NMF, to design and develop a fly-jib suitable for a range of scopes.
SAL Engineering director Karsten Behrens said, “It was essential that in addition to strong lifting capabilities that the fly-jib could be configured and could be used for various work scopes.
“It can be configured in a long (23m) or a short (13m) set-up and is adjustable to three different angles. It is designed to be interchangeable between our Type 183 vessels and can, with modifications to the existing jib, be installed on each of the cranes on the ships”.
