Maintaining the integrity of a vessel’s hull is essential for safe and efficient operations at sea. When damage occurs, timely and professional underwater repairs are crucial to ensure the vessel remains seaworthy and compliant with classification societies and maritime safety standards.

Hull damage can range from minor scratches and dents to significant breaches caused by collisions, groundings, or contact with submerged objects. Damage to the hull can lead to leaks, compromised structural integrity, and reduced performance.

At Master Tech, our classification-approved underwater hull damage repair services include the use of cofferdams, cutting, welding, and other specialized techniques to ensure your vessel remains compliant and seaworthy.

Our Repair Techniques Include:

• Cofferdams: Temporary, watertight enclosures used to isolate the damaged area from the surrounding water. This allows for a dry and controlled environment for repairs. We carefully install cofferdams to ensure they are securely sealed and provide a stable work area.
• Underwater Cutting: Our skilled technicians use underwater cutting tools to accurately cut and remove damaged or corroded areas. Precision cutting ensures minimal disruption to the surrounding hull structure.
• Welding: Employed to restore the hull’s structural integrity by joining new or repaired metal sections. We use underwater welding techniques to perform high-quality welds. Our welders are certified and experienced in performing repairs that meet classification society requirements.
• Post-Repair Inspections: After repairs, we conduct detailed inspections using advanced underwater NDT methods to verify the quality and integrity of the work, as required by the Client / Classification Society. Documentation and certification are provided as per classification requirements.
