Brunvoll Thruster EAL Upgrade: Protecting our waters with VGP compliance

Brunvoll Thruster EAL Upgrade: Protecting Our Waters with VGP compliance. Based on the aforementioned VGP requirements, Brunvoll has developed, tested, and implemented an EAL solution that is technically feasible for most thrusters within our product range. Our EAL solution adopts a split oil system, applying EAL in all direct oil-to-sea interfaces and conventional mineral oil in the gearbox. In our thrusters, oil-to-sea interfaces pertain to the propeller hub with blade seals and the propeller shaft main seal. The gearbox reservoir, containing mineral oil, is sealed with static seals, ensuring at least two barriers between the sea and the mineral oil.
