Working on vessels whether in dry dock or afloat.
Carrying out the full range of repairs including some of the largest and most complex ever undertaken including:

- Hot Straightening
- Blade Reshaping
- Blade Cropping & Re-tipping
- Welding & PWHT
- Propeller Polishing (<1µM)
MODIFICATIONS & SPECIAL PROJECTS
When in service the hulls of older vessels can become rough and fouled to the extent that the torque load imposed by the propeller on the main engine is dramatically increased. The resulting drop in propeller revolutions can reduce turbocharger efficiency and cause higher exhaust gas temperatures with the risk of damage to exhaust valves and cylinder liners. Bespoke propeller modifications, often carried out afloat, allow the engine to operate within its normal tolerances with no appreciable loss in either propeller efficiency or cavitation performance.
