NESL Restores Ship’s Conduit Pipe and Junction Box with Belzona 1311 & Belzona 5811
At NESL, we pride ourselves on delivering cutting-edge solutions to complex marine Enviornmental challenges. Recently, our team undertook a critical project to restore a severely corroded conduit pipe and junction box on a ship without any hot work at the location, showcasing our expertise in fabrication, repair, and advanced coating technologies. This case study highlights the step-by-step process we followed to bring this vital infrastructure back to peak performance, ensuring durability and reliability for our client.
The Challenge: Severe Corrosion Threatening Operational Integrity
During the initial inspection, our team identified profound corrosion in the ship’s junction boxes and conduit pipes. The condition of the junction boxes was compromised, with deeply corroded components posing a risk to the vessel’s electrical systems. The conduit pipe, a critical element for protecting wiring, had also suffered extensive damage. Left unaddressed, these issues could have led to operational downtime, safety hazards, and costly replacements.
Assessment and Preparation
The restoration began with a thorough assessment of the damage. After an initial cleaning of the deeply corroded conduit pipe, our technicians used power tooling to remove rust and debris, preparing the surface for repair. This meticulous preparation ensured a strong foundation for the subsequent steps.
Fabrication of New Components
To address the corrosion, NESL’s skilled engineers fabricated new flanges and covers from scratch. This process, carried out with precision in our state-of-the-art facilities, ensured that the replacement parts met the exact specifications required for the ship’s junction box system. The newly fabricated flanges were cold bonded to the junction boxes using Belzona 1311, a high-performance epoxy-based composite known for its exceptional adhesion and durability.
Repairing Profound Damages
The corroded flange and cover were removed, and repairs commenced immediately. Using Belzona 1311, our team expertly repaired profound damages to the conduit pipe and junction box. This advanced material not only restored structural integrity but also provided long-term resistance to future corrosion.
Protective Coating Application
To safeguard the restored components, we coated the flanges with Belzona 5811, an industrial-grade protective coating designed to withstand harsh marine environments. The final wrapping and coating were completed using Belzona 5811 in conjunction with reinforcement tape, ensuring a robust barrier against moisture, salt, and other corrosive elements.
Final Inspection and Results
The project concluded with an aerial view of the restoration, showcasing the seamless integration of the repaired and newly fabricated components. The conduit pipe and junction box were fully restored, exceeding industry standards for reliability and longevity. Our client was thrilled with the outcome, confident in the enhanced performance and extended lifespan of their ship’s infrastructure.
