SAL Heavy Lift has acquired a fly jib crane extension that can be installed on its Type 183 vessels, Lone and Svenja.
The modular design of the crane boom extension enhances the capabilities of the vessels’ cranes to reach further and lift higher, said SAL. The heavy lift vessel Lone is the first ship in SAL’s fleet to be fitted with the fly jib, making the crane hook approximately 70 m tall.
SAL added that the fly jib enables it to handle larger units, or work on projects where long components vertically need to be lifted vertically – offshore wind energy components, for example.
Sune Thorleifsson, head of marine projects at SAL, explained: “Our fly jib has long been on our wish list, but when a client recently approached us with the requirement to support on driving piles into the seabed for an offshore wind project, and the piles being so long that it was otherwise not possible to up-end them for installation, we saw the opportunity to realise this long-term dream.”
SAL’s fly jib has been designed by TTS-NMF – the manufacturer of the cranes on the Type 183 vessels – in close cooperation with SAL Engineering.
Karsten Behrens, SAL Engineering director, added: “It was essential that in addition to strong lifting capabilities, that it could be configurable in various modes hence adding to its applicability in various working scopes. Therefore, the fly jib can be configured in a long (23 m) or a short (13 m) 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.”
SAL also expects the fly jib to be used in oil and gas projects.
