Process module ready for Jotun FPSO

Here, the 40.3-tonne process module is being lifted aboard the Jotun FPSO production ship.

There is frantic activity in the workshop in Kvinesdal. For over a year, project managers, engineers, fitters, electricians, welders, and others have been working on the eight-metre-long, four-metre-wide and seven-metre-high steel colossus. Now the finishing touches are being put on.

– Some of the parts at the very top had to be dismantled, packed, and sent in individual pieces. There simply wasn't enough headroom in the workshop when the module was to be lifted onto the vehicle, says Head of Fabrication, John Vester Nielsen.

AFTER HAVING Having been driven a few hundred metres to the quay, the finished module will be transported by boat to Stavanger.

The project is part of the upgrade of the production ship Jotun FPSO, which is located at the Worley Rosenberg Stavanger yard.

PROCESS MODULE The boiler has been dismantled from the ship and moved to the workshop in Kvinesdal. Approximately 1000 parts have been dismantled, labelled and prepared for further extensive inspection and testing.

– It's an extensive engineering job, says Stanley Rafoss, who is heading the work to extend the module's service life.

All parts were thoroughly inspected before detailed engineering was carried out.

– It is important to have a lot of expertise and experienced personnel here, and close dialogue with the authorities' approval body, says Rafoss.

AT THIS STAGE The reports and data available are calculated and assessed. In this way, the lifespan of the components to be reassembled is documented and extended.

The fully assembled module is now ready for another 25 years of offshore service. It will meet the same requirements and qualities as a brand-new module of the same type, states Rafoss.

THE PROJECT IS as part of a delivery to Jotun FPSO's Lifetime Extension project. Halvorsen responsible for life extending all pressure vessels and heat exchangers in the onboard process plant.

– This is a good example of green and sustainable production. In addition, the costs of upgrading the old module are significantly lower than if the customer were to build an entirely new module, says Rafoss.
