Time Is Of The Essence For Testing On An Ocean Going Vessel


Built in 2013, Go Pegasus is a Norwegian designed AHTS (Anchor Handling Tug Supply) vessel, particularly suited for work in harsh environments. Its initial charter contract was worth some $40 million.

Loading Test Weights by CraneSliding Carriage Test with suspended Test Weights

Shaw Lifting was commissioned to carry out the over-load testing to Go Pegasus’s 60 tonne WLL (Working Load Limit) Hydralift ‘A’ frame. Working to a tight timetable to ensure minimum time for the vessel in port, and co-ordinating with DNV (Det Norske Veritas) surveyors who had to witness the test, we carried out Hydralift’s own Overload Test Procedure.

The first part of the test was to connect the test weights to the lift winch wire, which runs over the 60 tonne wire sheave on the ‘A’ frame. The test weights used were a total load of 66 tonnes, stacked and held in place by heavy duty ratchet straps.

Once the weights were connected to the winch wire, the weights were lifted by the winch and suspended for five minutes while the ‘A’ frame was operated.

On completion of the tests, the test weights were lowered to the deck, de-rigged and MPI

(Magnetic Particle Inspection) testing was carried out.

The vessel was able to return to work after a short time berthed in port, minimising berthing fees and time away from its valuable contract.
