Repairing the transformer is a cost-efficient solution, compared to exchanging the damaged unit. In most cases with leaking transformers, we are able to repair the transformer, using our specialized welding repair method. Our method is designed to reduce both downtime and cost of ownership, and thereby maximizing the availability and performance of your assets.
We have many years of experience within the field of welding repair sol
utions and hundreds of transformers still operating today. Our skilled employees are highly trained to carry out the procedure, making sure that the transformers can continue to operate without leakages and without the need for replacement.
Timeframe
The repairing process is smooth and fast and is performed without any drainage of the transformer. Depending on the leaks, the timeframe of the repair is typically 2-5 days, from inspecti- on of the transformer to completion of the final documentation.
The process
1.Detection & inspection The leaks are typically detected during an inspection, which leads to further inspections to identify and map the leaks. The process is fully documented.
2.Repairing process Repairing the leaks, using special developed on-site welding methods, thus reducing both downtime and costs significantly.
3. Testing & documentation Pressure testing and documentation to ensure that the transformer is sealed. The welding repair of the transformer is completed and documented.

Welcome to our new Head of Service
We are happy to introduce our new Head of Service, Jacob Olsen, who has recently become a valuable addition to our office in Esbjerg, Denmark.
'After almost 10 years of developing and building test machines that test wind turbines and components for the future, it will be exciting to see what challenges there are in the slightly older wind turbines that have a few years of operation behind them. I am looking forward to this role at 3WIS'
It's good to have you on board, welcome to 3WIS Jacob!

Offering global welding repair solutions - PES article about 3WIS
According to WindEurope’s latest analysis, Europe currently has 255 GW of wind energy installed, of which 19 GW are newly established facilities from 2022. WindEurope’s expectations for the future are that an additional 129 GW will be established in Europe between 2023 and 2027. To meet the 2030 climate goals, the expansion is expected to especially speed up from 2025 to 2027. Based on these predictions, the Danish company 3WIS has expanded its portfolio of repair solutions to include engineering consulting.
3WIS is highly specialized in complex repairs of steel structures on wind turbines and offshore foundations and has accelerated the development of the company by establishing an engineering department. This is built on the foundations of in-house expertise and knowledge, accumulated over the years with highly specialized and complex welding repairs of wind turbines. This includes up-tower and on-site welding repairs, as well as feasibility studies, root cause analysis, and initial validation of repair solutions in our facilities in Denmark.
Recently we welcomed a new colleague at 3WIS as Jacob Olsen, who started as our new Head of Service in Esbjerg's office.

Replacement of piping system at Højby Pumpestation
Højby Pumpestation is a heating facility within the heating district of the Danish Island, Funen.
Recently we completed a campaign at Højby Pumpestation, which included cutting down the existing piping system and replacing it with new components, including all pipes and pumps from the floor.
When dealing with maintenance, replacement, and construction of piping systems at district heating plants, we need to operate fast and firm as it involves shutting down the district heating, leaving residents without heat for several hours.
Within 15 hours we were able to remove the existing components and placing the new bends. Thereafter, we completed the campaign by building up the rest of the piping system.
Thank you Fjernvarme Fyn A/S for the trust to service and maintain your heating facilities and of course a big thank you to our service technicians for doing a great job.
