Vessel repairs and support at sea

Normally, large electrical rotating machines are removed from a ship in berth or dry dock. This often requires dismantling surrounding equipment or main support structures and cutting a hole in the ship’s side. Sulzer has the expertise to repair most rotating machines in-situ. Whenever you call us, our experienced and highly skilled engineers fly to meet the ship wherever it is, and provide the service that helps you minimise cost and downtime.

With many possible service solutions, we can help our customers in a unique way.
Dedicated to thinking long term, our experts focus on maximising equipment life.

Land-based service for the maritime sector

While our engineers are onboard dismantling the equipment, we are manufacturing new coils at one of our special facilities around the globe. Once completed and tested, the coils are dispatched to the vessel in time for Sulzer’s engineers to seamlessly carry on with the repair.

Our coil workshops are among the best-equipped coil manufacturing facilities in the world, capable of producing all types and sizes of AC coils and bars, DC coils and Rogowski coils.

An in-house, highly sophisticated copper rolling mill has both inline and pot annealing facilities, enabling us to offer a round-the-clock coil manufacturing capability, with an incredibly short lead time on copper strip. Extensive stocks of continuously cast soft copper rod guarantee the ability to meet your demands immediately.

Formed coils are produced on automatic shaping machines, which give consistent geometry and coil fit. Computer-controlled taping machines provide perfect lapping and consistent tension, giving built-in security of coil insulation.

A range of electrically heated hydraulic presses up to 24ft (7m) guarantees highly accurate size and consistent control of pressed coil sides, ensuring a perfect slot fit. All packing and transportation of our products have to pass stringent quality controls so that the care taken in manufacture is in no way compromised en route to the customer.
