- Blade foot O-rings replacement
- Shaft seals replacement
- Top seals replacement
- Pinion shaft removal
- Bearings replacement
- Inspection/overhaul of OD box
- Quick scan of gear set
- Blade repair
- Hub inspection and repair
Marine OD Box (Oil Distribution Box)
Marine OD box (Oil Distribution box) repair involves specialized overhaul services for Controllable Pitch Propeller (CPP) systems, focusing on seals, bearings, and gears, often done in-situ or in workshops by experts from our Team. These repairs reduce downtime, prevent oil loss, and ensure smooth, fuel-efficient propulsion by addressing issues like worn parts, leaks, and alignment, covering major brands like Wartsila, Hundested, and more.
- Seal Replacement – Replacing worn O-rings, oil seals, and bonded seals to stop oil leakage.
- Component Overhaul – Inspecting and replacing gears, bearings, and other internal parts.
- Shaft Line Alignment – Ensuring proper connection and alignment with SKF couplings and the propeller shaft.
Controllable Pitch Propeller (CPP)
Marine Controllable Pitch Propeller (CPP) repair involves expert servicing for blade damage (welding, straightening, grinding), hub/internal mechanism fixes (seals, bearings, hydraulics), and full overhauls, often by OEMs like Everllence/MAN or Wärtsilä, focusing on restoring balance, efficiency, and reliability through planned maintenance, advanced NDT, and lifecycle support, with underwater repairs possible for minor issues.
- Blade Repairs – Welding material, crack repair, straightening bent blades (using induction heating), tip renewal, and re-grinding to original geometry.
- Hub & Internal Mechanism – Replacing seals (O-rings), bearings, pistons, and control rods; addressing hydraulic leaks and pressure loss; reconditioning the pitch control system.
- Balance Restoration – Critical after damage to eliminate vibration, involving precise measurements and adjustments.
Stern Tube Repair
Marine stern tube repair involves fixing leaks and wear in the shaft’s sealing system, using in-situ line boring for shaft alignment, replacing worn lip seals or face seals, applying Teflon-based additives (like STERN TUBE+) for minor leakage or wear reduction, or even underwater seal replacements to avoid drydocking, with services ranging from urgent bearing manufacture to full overhauls for oil & EAL systems. Specialized companies offer global support for these critical propulsion system repairs.
- Seal Replacement – Replacing worn lip seals or face seals to stop leaks, often done with specialized engineers to ensure correct alignment and testing.
- In-Situ Line Boring – Precision machining (boring) the stern tube bore to restore perfect alignment and diameter, critical for bearing longevity, especially on large vessels.
- Leak Stop Additives – Injecting Teflon-based products (like ABCON STERN TUBE+) into the system oil to create a barrier, significantly reducing or stopping minor leaks (15-100L/day) and protecting components.
- Bearing Repair/Manufacture – Emergency services exist for rapid manufacture or repair of stern tube bearings, sometimes using laser cladding for superior quality.
