Aibel under way with Troll C option

Following a successful FEED study, Aibel was awarded the EPCI contract for a new gas module for the Troll C platform. The module will handle increased production from the Fram field.

The contract was an option in the initial contract with Statoil for the FEED study, and comprises engineering, procurement, construction and installation (EPCI). Aibel holds comprehensive experience from larger modification projects at the Troll field and thereby has good understanding of the challenges and possibilities at the platforms. The project is managed from Aibel’s office in Bergen, where mobilization of personnel, office spaces and systems quickly were put into place.

“The management team is the same one involved in the Oseberg Vestflanken 2 project, which is now in its final phase. This means we already have good internal procedures and systems in place. At the same time, we will soon have around 70 people in situ who will be responsible for engineering and procurement. This is a little earlier than planned, but will also ensure that we don’t fall behind in the initial phase,” says Project Manager Jarle Thorstensen.

Focus on procurement

One of the most important success criteria is to ensure that necessary clarifications are provided to put in place procurement packages for elements with long lead times. This is crucial if the project is to avoid being delayed.

“The compressor for the gas module was ordered by Statoil during the FEED phase, while we placed several of the major procurement packages immediately when the option was exercised. Nevertheless, there remains a lot of work to do as we must ensure that we supply the best possible product at a good price. This is why we are constantly challenging the engineering, the market and the customer, and are looking for better and cheaper solutions,” says Thorstensen.

Engineering and procurement are now in a busy period during the autumn and winter until the start of production in Haugesund in May 2018. At that time, approx. 60 employees will be engaged in the construction of the 470-tonne gas module. In the course of the spring 2019, the module will be transported to the field for installation. Approx. 30 people will perform the reconstruction and installation work offshore.

The contract has a value of a little more than NOK 600 million.
