Johan Sverdrup Offshore Deaeration Vessel

One project that has persevered through the industry downturn is the Johan Sverdrup Project, Statoil are the operator behind this large scale project which is one of the biggest projects based in the Norwegian sector of the North Sea.

The Johan Sverdrup Project is in full swing with large scale main equipment packages now coming through final inspections and being made ready for shipments.


The latest kit being made ready is their offshore deaeration vessel, which is destined for use on the Johan Sverdrup oilfield on the Norwegian shelf, the package has been successfully weighed by lifting and rigging equipment expert Rope and Sling Specialists (RSS).

The UK firm also provided rigging equipment (including round slings and shackles) and load cells (from load cell manufacturer Straightpoint) for the procedure.

Furthermore it successfully proof-tested a spreader beam which will be used to place the deaeration vessel in to its final offshore destination.

Measuring 28.3 metres in length by 5.6 metres in diameter, the deaeration vessel is a large structure which was calculated to weigh a mammoth 116.1 tonnes.

These calculations were created utilising a Mega Lift from engineering solutions specialist provider, Ainscough Industrial Services to assist temporarily lift the vessel.


Four 150-tonne capacity wired compression load cells from Straightpoint were placed underneath the structure at predetermined positions.

The vessel was then lowered onto the load cells and weighed, centre of gravity measurements were taken using Straightpoint’s desktop controller data logging software package. Two temporary stools weighing 2.4 tonnes each also needed to be factored into the ultimate calculations.

A number of high profile firms were included in the project as a whole. Offshore plant equipment manufacturer, Charles Thompson, loaded out the vessel, which was manufactured by deaeration specialist ETA Process Plant, who are part of the Koch-Glitsch group.

According to Steve Hutin, managing director at RSS, “The myriad leading global brands that were connected with the manufacture, transportation, lift and use of the vessel turned it into an extremely rewarding and positive project.

It’s interesting, and uplifting, that the onward journey of this particular giant offshore unit was dependent upon the safe and efficient application of our below-the-hook technologies, knowledge and equipment.”
