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 Energy
Last week we welcomed a new colleague at 3WIS as Mads Rasmussen started as our new Head of Energy and had his first day at our office in Munkebo.
Mads will be responsible for managing our energy projects and will continuously work on extending our portfolio of heating district suppliers, biogas suppliers, power-to-x clients etc.
About his start at 3WIS, Mads states:
“I have been looking very much forward to starting my position at 3WIS and especially to get back to the Energy Industry, which is a great passion of mine. I have had an amazing start at 3WIS and have already been working on several district heating projects. Feel free to contact me if you would like to know more about how we can help”.
Mads has a background as mechanical engineer and comes to 3WIS with several years of experience from the Energy Industry. Previously Mads has been taking on positions as both Sales Manager and Project Manager on national and Scandinavian markets.
Once again, a warm welcome to Mads. We are looking very much forward to working with you 👊

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.

Local presence, local support: UK team of highly trained inspectors
Our UK based NDT & Inspection team, led by Stephen Chambers, carry out major on and offshore inspection methods for aging turbines or turbines that are new in service. Our catalogue of inspection methods ranges far and wide, and among others we can mention: 𝗘𝗱𝗱𝘆 𝗰𝘂𝗿𝗿𝗲𝗻𝘁 𝘁𝗲𝘀𝘁𝗶𝗻𝗴 (𝗘𝗧)
A method performed on mainframes and turbine towers that makes us capable of testing issues without the need to remove paint to identify flaws in metal surfaces and welds.
𝗠𝗮𝗴𝗻𝗲𝘁𝗶𝗰 𝘁𝗲𝘀𝘁𝗶𝗻𝗴 (𝗠𝗧)
Non-destructive testing which can detect surface and subsurface defects of the welds, used post ET if any indications found with the latter method.
𝗨𝗹𝘁𝗿𝗮𝘀𝗼𝗻𝗶𝗰 𝗧𝗲𝘀𝘁𝗶𝗻𝗴 (𝗨𝗧):
By sending ultrasonic waves through a structure or material, we can detect potential flaws in key safety points in e.g., ladder welds and platforms. 𝗣𝗵𝗮𝘀𝗲𝗱 𝗔𝗿𝗿𝗮𝘆 𝗨𝗹𝘁𝗿𝗮𝘀𝗼𝗻𝗶𝗰 𝗧𝗲𝘀𝘁𝗶𝗻𝗴 (𝗣𝗔𝗨𝗧)
An advanced NDT technique that detects defects in metal and composites and provides us with accurate and detailed information about the depth, size, and severity of the defect. 𝗢𝘃𝗲𝗿𝗮𝗹𝗹 𝘃𝗶𝘀𝘂𝗮𝗹 𝗶𝗻𝘀𝗽𝗲𝗰𝘁𝗶𝗼𝗻
The inspection is performed on both aging turbines and turbines that are new in service, using rope access or drones to inspect e.g., the blades of the turbine, main structures, and internal frames. If flaws are detected, further inspections and solutions can be implemented to prevent down time of assets. Do not hesitate to contact us if you would like to know more about our advanced NDT and inspection methods and how we support both locally and globally. Contact info right here.

Stiesdal - Offshore floating foundations
Translating practical experience into theory: supplying specialized welding and NDT knowledge to the concept development of Stiesdal’s Tetra-range of modular offshore floating foundations.
Stiesdal Offshore A/S develops and commercializes solutions with the aim of mitigating climate change. During the concept development of their offshore floating foundation, 3WIS got involved as advisors during the design and concept phase.
About the collaboration, Per Hyldahl, Chief Engineer at Stiesdal Offshore A/S, says:
”During the concept development, we were looking for external competencies and sparring regarding the welding and NDT. Therefore, we contacted 3WIS who brought both expertise and practical experience into the dialogue. Especially their practical experience made sure that we had thought it through – from initial design to final execution – which also shed light on challenges and solutions we had not immediately identified”.
Thank you for the trust and possibility to bring our specialized knowledge into play during this exciting development for the future floating wind industry.
