Lightship Gannet 1954

Saltwater Engineering carried out some measuring on the lightship Gannet 1954.


Since Lightships were used in waters that are too deep or otherwise unsuitable for lighthouse construction. The type has become largely obsolete; lighthouses replaced some stations as the construction techniques for lighthouses advanced, while large, automated buoys replaced others. This particular light ship once provided accomodation to a crew of 10. The primary duty of the crew was, of course, to maintain the light, but they also kept record of passing ships and also observing the weather conditions.

Lifting and relocation

The new owners have plans to lift and permanently place the ship ashore to transform it into a restaurant/bar.
The ship is currently being stripped from the old interior and heavy, no longer needed accessories. Saltwater Engineering was asked to carry out a quick lightweight check in order to determine the actual weight of the vessel. Once this has been determined the actual design of the four lifting points and strength of the deck of the vessel will be completed. Typically a vessel like this would be lifted using belly slings, however in this specific case belly slings are not an option. This results in the design and integration of trunnions that will be welded into the vessel at four strategic points allowing for the safe execution of the lifting and relocation.
