The second out of three Troll modules left Aibel’s yard in Haugesund on Tuesday evening, and set sail towards the Statoil-operated Troll field in the Norwegian part of the North Sea.
At the same time in the North Sea Hall, departure for the third and final module is close. The three modules will contribute to extending the production time of the Troll platform, which is the centre for gas deliveries to clients at the continent.
A few hours prior to departure, a content project manager stated that everything was going according to plan.
“We are ready to hand over an exemplary module,” says Bruce McPherson, Aibel’s project manager on the Troll 3&4 project.
“This is how things are supposed to be; A high quality delivery, on time and at agreed price,” says McPherson.
A long way towards Troll
The M11 module arrived at Haugesund on 17 May after nearly a month on sea. In Haugesund, the crane was installed and tested on the 23 metre high module. In addition, a number of checkpoints have been looked over. On 3 June the module was ready for next stage.
“It is an optimum situation both for the client and us that we now have carried out all work possible prior to the transport to the field. The major construction part has been performed in Thailand, where we started out in January 2013. Our yard in Thailand delivered a first-class module and obtained good safety results. Also here in Haugesund everything went according to schedule,” says McPherson.
Once at the field, in the North Sea, the module will be lifted on board the platform by Saipem. In this phase, Aibel only has few employees at the field.
Next is M13
The third module still stands in the North Sea Hall at Aibel’s yard in Haugesund. This module contains equipment that will convert electricity after it has travelled around 70 kilometres from shore. Everything is progressing according to schedule, and the module is being prepared for transport to the field where it subsequently will be lifted on board the platform. M12 was already installed last year.
The new compressors will make it possible to produce gas from the Troll field until the year 2063, according to information at Statoil’s website. The compressors will be powered by electricity from shore, and the platform will get a new power cable.
The new compressors are necessary because of reservoir pressure decreases as the gas is extracted. They ensure that the Troll gas can be transported into the Kollsnes processing plant. The gas is then forwarded to the continent.
