Successful cutting assignment on the Tyra field

Successful cutting assignment on the Tyra field

Beerenberg has completed another advanced cutting assignment, this time for Heerema Marine Contractors SE on the Tyra field in Danish sector.

This scope was quite challenging as the diamond wire cuts had to be made with extreme precision. 

“The assignment consisted of cutting and securing of concrete-filled legs of the platforms as well as two support members. Due to the fact that the jacket construction will later on be reused for new topsides, the cuts had to be extremely precise, with a tolerance of only +/- 5mm and an angle of 0.5 degrees”, explains project manager Bertil Bargård.  


Before the actual work could commence, several test cuts on a full scalemock up test piece were carried out at Beerenberg's workshop in Bergen, Norway.  
“Valuable lessons learned from these tests were incorporated into the project execution.”

Competent crew  
At the beginning of May 2020, Beerenberg's crew (three persons) traveled to Denmark for a two-week quarantine period. After this period, they were approved to mobilize to the offshore location for a three week diamond wire cutting campaign. They were eventually replaced by two colleagues who completed the scope of work. All are experienced operators and supervisors in the field of diamond wire cutting. This knowhow was the main reason for Heerema Marine Contractors to award this contract to Beerenberg. 

"In addition to an efficient project organization, including the operators in the development of the method statement, close collaboration with customer, flexibility in method statement + tooling in combination with high competent personnel are the key to success", says Sverre Brufladt, head of the ECT department that carried out the assignment. An example of this is that even with delays in the project, the crew managed to complete the mission several days ahead of schedule.  

"Together with operators and supervisors, we have prefabricated and fine-tuned our own equipment for this challenging  assignment. This process has been particularly successful and we have shown the enormous competence that lies in Beerenberg", says Bertil Bargård.  


Multidisciplinary approach  
In addition, the project manager function has also been a key factor in the  
implementation of the assignment, not least through very good communication with the client Heerema.  
“A new practice is that our engineering goes hand in hand with the client and sparring through the process. On the whole, our project managers take care of many roles at the same time. This both contributes to a good flow of information while keeping the engineering on point”, says Sverre Brufladt.
