SAL Heavy Lift is installing Fly-Jibs on the main booms of the cranes of its Type 183 vessels (LONE and SVENJA) to extend their lifting height and outreach
The height of up to 70m is regarded by SAL as a significant step forward in its heavy lift services to clients in the offshore renewables and oil & gas markets.
Sune Thorleifsson, Head of Marine Projects at SAL, explained: “A client recently approached us with the requirement to support on-driving piles into the seabed for an offshore wind project. The piles were so long that it was otherwise not possible to up-end them for installation, so we saw the opportunity to realise our long term goal to fit a Fly-jib."
SAL Heavy Lift’s sister company SAL Engineering worked with crane maker TTS-NMF to design and develop a demountable and modular design suitable for a wide array of lifts.
Karsten Behrens, Director of SAL Engineering, explained that the Fly-jib can be configured in a long (23m) or a short (13m) set-up and is adjustable in 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."
The Fly-Jib is designed to withstand the forces occurring during a sea voyage and can be installed using only the vessels’ existing cranes.
