Underwater Propeller Repair

Propeller damage can manifest in various forms, each impacting vessel performance:

•Bent Blades: Often resulting from collisions with submerged objects or ice, bent blades can increase fuel consumption and cause vibrations.

•Cracks: Stress or impact can lead to cracks, which, if untreated, may propagate and compromise structural integrity.

•Corrosion: Prolonged exposure to seawater can cause corrosion, weakening the propeller material.

•Cavitation Damage: Irregular water flow can create vapor bubbles that collapse on the blade surface, leading to pitting and erosion.

Our Repair Services

FN Diving offers a suite of underwater propeller repair solutions tailored to address these issues:

Underwater Propeller Straightening: Utilizing advanced cold static load press machines, we can straighten severely bent blades underwater, restoring them to their original design and ensuring optimal performance.

Crack Repair and Propagation Control:

Our technicians perform meticulous inspections to identify cracks and employ specialized techniques to repair and halt further propagation, maintaining the propeller’s structural integrity.

Static Balancing:

Ensuring the propeller’s balance is crucial for smooth operation. We conduct on-site static balancing calculations to minimize vibrations and enhance efficiency.

Replacement of Controllable Pitch Blades and Blade Seals:

For vessels equipped with controllable pitch propellers, we offer underwater replacement of damaged blades and seals, ensuring seamless operation without the need for drydocking.

Restoration of Hydrodynamic Edge Contours :

Damaged edges on propeller blades can disrupt water flow, reducing efficiency. We restore these contours to their original specifications, improving performance and reducing fuel consumption.

Pitch and Camber Alterations on Ship Propeller blades: Adjusting the pitch and camber of propeller blades can correct issues like engine overload or cavitation. Our team uses precise underwater pitch meters to make these adjustments accurately.

Full Thruster Repairs and Complete Unit Replacement: Beyond propellers, we handle comprehensive thruster repairs and replacements, ensuring all aspects of your vessel’s propulsion system are in optimal condition.
