Metalock Brasil has completed a cold structural repair on the auxiliary engine No. 4 block of an international-flagged merchant vessel during an operation carried out at the Port of Kingston, Jamaica, reinforcing its expertise in technical solutions applied to marine engines in operation.

The service was carried out on the auxiliary engine block, cylinder No. 2, following the identification of a damaged area measuring approximately 300 × 250 mm with a thickness of 20 mm, which compromised the structural integrity of the component. The intervention was performed directly on board while the vessel was berthed at the Port of Kingston, avoiding the need for block replacement and reducing vessel downtime.

The scope of work included full preparation of the damaged area, with removal of the fractured section, controlled cutting and surface adjustment to ensure the proper fit of a new insert. Subsequently, a custom-made insert was manufactured and installed, designed to restore the affected region of the engine block.

The insert was secured using the Metalock® cold repair process, applying Metalock® keys and studs, ensuring restoration of the structural strength of the assembly without the introduction of heat. After installation, surface finishing was performed to ensure proper leveling of the repaired area.

As a final stage of the service, new drilling and thread machining were carried out, allowing for the reinstallation of the engine cover and side plug. All alignment of the repaired surface was referenced from existing intact areas, strictly following the applicable technical procedures.

After completion of the work, the repair was inspected and approved by the vessel’s onboard technical team, releasing the auxiliary engine for operation.

With a well-established presence in the Marine sector, Metalock Brasil is a recognized reference in precision structural repairs on engine blocks, component restoration and in-situ engineering solutions, offering technical alternatives that avoid complex replacements, reduce vessel downtime and enhance operational reliability.
