OFFSHORE DEAERATION VESSELS BENEFIT FROM BARNSHAWS’ PLATE ROLLING EXPERTISE

Metal bending experts Barnshaws’ Hamilton Branch has delivered 11 rolled steel cylinders to form two deaerator vessels destined for the Johan Sverdrup oilfield in the North Sea. Barnshaws has built a formidable reputation in supplying metal fabrications for challenging projects, with the business’ Hamilton Branch now utilising these skills in support of the highly demanding offshore oil and gas industry.

Barnshaws was awarded the opportunity to supply the curved steel elements to the Loftesnes bridge, a project executed by the general contractor Porr. The NOK 238 million structure has been designed to replace an aging bridge across the Sognefjorden fjord that was installed in 1954. The new bridge will allow traffic travelling the Rv 5 route to cross the fjord easily upon completion.

The customer - a leading supplier of vessels, tanks and piping to the offshore industry - has worked closely with Barnshaws in the past. When it came to deliver the 11 rolled cylinders for the deaeration vessels within a constrained timeframe, the supplier contacted Barnshaws for a high quality, prompt solution.

Work was required to be carried out within 3 weeks, meeting transport arrangements and ensuring the deaeration vessels could be installed on the offshore platform as quickly as possible. Barnshaws rolled 35 tonnes of steel plate at 16mm thickness to a diameter of 3.8 metres, producing the 11 finished cylinders.

Ensuring quality took precedence during the work. Offshore platforms are hazardous working environments where safety and space efficiency are of the utmost importance, so the rolled cylinders had to adhere to stringent quality levels.

John Chalmers, Company Manager at Barnshaws’ Hamilton Branch, said: “We were able to complete this work within the allotted timeframe, while meeting the high quality standards of the offshore oil and gas sector. Our innate capability in precision curving metal fabrications means we can deliver bespoke fabrications of almost any size quickly, while our Scottish location puts us in an advantageous position for marine and offshore customers in the region.”
