A Case Study on High-Pressure Cleaning for Enhanced Durability and Efficiency
Overview
In the maritime industry, maintaining a vessel’s structural integrity is crucial for operational efficiency, safety, and longevity. Over time, ships are exposed to harsh marine conditions, resulting in corrosion, rust, marine growth, and coating degradation. If left untreated, these issues can lead to metal weakening, increased fuel consumption, and costly repairs.
VU Marine, a leader in ship maintenance and retrofit solutions, successfully executed a hydro blasting project for a bulk carrier, significantly improving its performance, efficiency, and lifespan. This case study highlights the process, challenges, and impact of hydro blasting on the vessel.
Project Details
🔹 Client: International bulk shipping company 🔹 Vessel Type: Bulk Carrier 🔹 Scope of Work: Hydro Blasting for hull and deck maintenance 🔹 Location: UAE Dry Dock Facility 🔹 Objective: Remove heavy corrosion, marine growth, and deteriorated coatings to restore vessel efficiency
The vessel had been in operation for over 10 years without major hull and deck cleaning. Due to continuous exposure to seawater and pollutants, the ship developed significant rust, paint deterioration, and fouling, affecting its performance and compliance with maritime regulations.
The client approached VU Marine for an eco-friendly, effective, and time-efficient cleaning solution. After assessment, our team recommended hydro blasting, a high-pressure water jetting technique, as the best method to restore the vessel’s structure without causing damage.
Challenges Faced
1️⃣ Extensive Marine Growth & Corrosion
- The hull was covered with thick biofouling and corrosion patches, leading to increased drag and higher fuel consumption.
2️⃣ Tight Schedule & Quick Turnaround Required
- The vessel had a limited window for maintenance before its next deployment.
3️⃣ Environmentally Safe Cleaning Solution Needed
- The client required a chemical-free and eco-friendly cleaning process to meet regulatory standards.
Hydro Blasting Process by VU Marine
To address these challenges, VU Marine’s expert maintenance team implemented a systematic hydro blasting procedure:
Step 1: Pre-Assessment & Planning
✅ Conducted a detailed inspection to identify high-corrosion areas
✅ Determined optimal pressure levels to remove contaminants without damaging the metal
✅ Developed a strategic cleaning plan to complete the project within the deadline
Step 2: High-Pressure Hydro Blasting Execution
💦 Used ultra-high-pressure (UHP) water jets (up to 40,000 PSI) for hull and deck cleaning 💦 Removed thick layers of marine fouling, rust, and deteriorated coatings 💦 Ensured precision cleaning in sensitive areas such as bulkheads and ballast tanks 💦 Applied controlled pressure techniques to prevent structural weakening
Step 3: Quality Inspection & Surface Protection
🔍 Conducted post-cleaning thickness testing to assess metal condition 🔍 Verified complete removal of contaminants to prepare the surface for recoating 🔍 Recommended protective coatings to enhance corrosion resistance
Results & Impact on Vessel Performance
Following the successful completion of the hydro blasting process, the vessel experienced significant improvements in performance and longevity:
✅ 1. Enhanced Fuel Efficiency & Speed
🔹 30% reduction in hull drag, leading to lower fuel consumption 🔹 Improved hydrodynamic efficiency, allowing smoother navigation
✅ 2. Extended Vessel Lifespan
🔹 Removal of corrosion and biofouling prevented further metal deterioration 🔹 Structural integrity restored, adding 5+ years to the vessel’s service life
✅ 3. Compliance with Maritime Safety & Environmental Standards
🔹 Met IMO (International Maritime Organization) and SOLAS regulations 🔹 Eco-friendly, chemical-free solution reduced environmental impact
✅ 4. Reduced Maintenance Costs
🔹 Prevented the need for costly steel replacements 🔹 Extended paint coating durability, reducing repainting frequency
✅ 5. Quick Turnaround Time
🔹 Completed within 3 days, allowing the vessel to return to service as scheduled
