First norwegian ISS supplier with record digital project

Beerenberg recently completed a record-breaking project which saw the company measure up and supply insulation boxes using scanning and 3-D design. Much of the process was digitalised. The project, which was commissioned by Linjebygg, took place on the new gas...

Beerenberg is the first Norwegian ISS specialist to complete an insulation project of this size.
“We have carried out similar work on other projects, but they were nowhere near as big as the Dvalin project,” says project manager Hanne Lillegård.
The scope of the Beerenberg delivery was almost 700 insulation boxes. Beerenberg was hired by Linjebygg, which had been awarded the entire insulation scope of work, including installation of the boxes.

Until recently, surveying was always done by having a person in the field manually measure every valve and flange.
“With this kind of traditional surveying, it is very much up to each surveyor to assess the design of each box since there are almost always non-standard measurements and requirements. This is usually a time-consuming process because the different box types, sizes and shapes make the job very complex,” she says.

A digitalised documentation system

Large parts of the process on the Dvalin project were digitalised, something which saved time overall.
“Once the survey has been completed, an email is sent directly from the scanner to a digitalised documentation system that includes 3-D models, pictures and other technical data,” Lillegård explains.

Having all relevant information in a single location made the job easier for everyone involved. However, careful preparation is essential.
“Before we can even start the survey we need every bit of information for the job package from the client, including Excel lists, ISS drawings and specifications. I must say that our client, Linjebygg, did an incredibly good job in that respect,” says Lillegård.

Close co-operation

Co-locating the different teams also contributed to the success of the project.
“It was important that the execution phase was optimal. The design and production teams were based in a single location, making it easier when clarifications were needed. We also had the help of an experienced insulation engineer, Trond Ullestad, who supervised, quality-assured and approved the drawings prior to production. By working so closely together we were able to overcome minor issues quickly and efficiently while making decisions as we went along,” says Hanne Lillegård.

Retaining a joint design team for the duration of the process also helped ensure the quality of the solutions.
“It has been very useful to have the same people make all the assessments and decisions throughout the execution phase. That way we have gained a deeper insight into the way other people work, and everyone involved in the project has developed a common understanding and trust in each other’s expertise”, Hanne Lillegård says.

Numerous benefits

Beerenberg engineer Thomas Poulsen Hansen has been involved in developing the 3-D scanning method, and he is convinced that this kind of survey will generate numerous benefits for both the company and its clients in the future.
“One of the advantages is that it is much quicker than traditional surveying. This particular job took us around 2 1/2 months, something which would have been extremely difficult using traditional methods.”

A shortage of manual surveyors is another reason why digitalisation is becoming increasingly important.
“It can be difficult to source this kind of expertise, and in many cases it creates a bottleneck for the projects. We have to think new and look at how to best solve this on future projects. Digitalisation has been an important development for us in this respect,” he says.

Beerenberg has already used the technology on a number of projects.
“We have acquired considerable experience of scanning and 3-D design from various projects. It is creating benefits in the form of time savings and improved quality of solutions and designs, which in turn cuts non-conformities and reduces the need for modifications at a later stage,” Thomas Poulsen Hansen concludes.

Facts:
The Dvalin gas field is located some 15 km north-west of the Equinor-operated Heidrun platform and 290 km from the Nyhamna processing plant. The first gas delivery from the field is expected in 2020.
