Oil Conversion

Oil Conversion in Wind Turbines
Oil conversion on windmill in progress.


As one of the most critical components, the gearbox must operate under extreme stresses and operating conditions. Its critical parts, bearings and gears, must be protected by a lubrication fluid free of contamination and water.Only with the highest cleanliness can the gearbox sustain years of operation under some of the most demanding conditions anywhere. Although the equipment and lubricating oil

may be improved and designed to a maximum lifetime, the possibility of a need for oil conversion over the years can never be entirely eliminated.

Ocean Team has many years’ experience in oil conversion and flushing of geared and hydraulic blade-pitch and braking systems in onshore wind turbines. In wind turbines, gear oil can be changed in just a single lifting operation. With Ocean Team’s oil conversion and flushing system, the operation can be performed quickly and safely for personnel, wind turbine and the environment.

Gear oil systems on offshore wind turbines can now be changed in even relatively rough seas thanks to Ocean Team’s new, hydraulic, wave-compensated, gear-oil conversion and flushing system, now available to the international offshore market.Our new system solves many of the existing challenges of maintaining offshore wind turbines. The system, specially developed by Ocean Team, allows any vessel to pump oil from the gear systems in the nacelle into tanks on board the ship without the equipment being damaged due to rough seas or wind. The integrated hydraulic systems simply compensate automatically for the vessel’s movement in the sea.The hoses are equipped with a “weak link” safety device and patented valve system. If tension on the hoses becomes uncontrollably high (over-pull), the weak-link will break immediately, causing the hose to separate from the nacelle in a safe, controlled manner, thus reducing the risk of physical damage or oil spilling to the greatest possible extent.


Safe, efficient and time saving

The closed conversion system consists of just three main processes:

2)    Gear flushing

All processes are controlled by the oil conversion system, ensuring optimum oil and gear cleaning in a quick, efficient and safe way with minimum risk of oil spillage to the environment. The system offers a perfect solution to a major practical problem in the growing market of offshore wind turbines while meeting all requirements and specifications on environmental protection. It’s another example of the ingenuity in Ocean Team when searching for better solutions to the benefit of our customers.3)    New oil filtration and filling
