Recently Hydrex diver/technicians carried out afloat propeller operations on vessels in Belgium and the Netherlands.
In Antwerp the damaged blades of a 190-meter roro vessel were cropped, while in Amsterdam and Rotterdam the propeller blades of two 229-meter bulkers were modified to allow the ships to save fuel while sailing at lower RPM.
A ship with bent or cracked propeller blades might experience severe vibrations while sailing. The classification society might demand a repair before the vessel is allowed to sail on. By straightening the blades or cropping them, Hydrex can restore the propeller’s balance, resulting in a green light from the class for the vessel.
We do not only offers repair services, but can also help customers when they have the need for preventive or other special custom projects.
A good example of this is the project that was carried out on two sister vessels. These 229-meter bulkers were going to sail at a lower RPM. A modification of the propeller blades’ diameter would allow them to save fuel while doing this. The operations were performed without disrupting cargo operations.
Over forty years of experience with propeller repairs have given us the tools and know how to offer fast repair and modification services to vessels around the world. All types of operations can be carried out fast, fluently and efficiently afloat and underwater.
