Exhaust duct for Veslefrikk


Halvorsen Offshore has been awarded the total contract for a new exhaust duct for Veslefrikk.

The installation will take place during a production stoppage in September to October.
The exhaust duct is just under one and a half metres in diameter and up to 40 metres long. At the time of writing, it is in pieces and ready to be loaded and transported to Veslefrikk. Halvorsen Offshore is responsible for the entire production process; technical design, engineering, construction, production and installation.
"This is a tailor-made delivery. Every component has been manufactured according to precise measurements," explains Project Manager Espen Pilskog, regarding the project which is worth NOK 6-7 million.
In addition to the actual pipe parts, the project involves a number of oscillation compensators. These are designed to absorb the movements of the platform and are made from steel or rubber. Halvorsen Offshore shall also be producing the construction which attaches the exhaust duct to the platform deck.

Short deadlines
It will take 7 large containers to transport the 24 tons of material to the North Sea. Eight employees from Halvorsen Offshore have been assigned to the installation work, during a stoppage in production of just under one month.
"We are facing a number of logistic challenges as several other projects will be running on parallel during the platform's downtime. The entire project has very short deadlines and it will be an exciting challenge to complete everything in time. A number of the project group members have experience of similar projects on the Heimdal field, and our feedback from Statoil has been purely positive," confirms Espen Pilskog.
