When a bulk carrier finishes discharging multiple grades of heavily staining commodities like coal, the commercial clock starts ticking. For ship operators and charterers, the goal is clear: transition the vessel to a strict grain cleanliness standard as rapidly as possible to prevent costly off-hire penalties and port delays.
However, relying solely on an already burdened ship's crew can create severe operational bottlenecks. This was precisely the challenge facing the 7-hold bulk carrier MV BELMONTE after discharging three distinct grades of coal at the port of Ploče, Croatia.
The Commercial Challenge: Crew Estimates vs. Real-Time Deadlines
The vessel’s upcoming charter demanded immediate loading of sensitive agricultural grain at Barcarena, Brazil. Upon assessing the heavy coal staining and widespread structural oxidation across the holds, the ship’s crew estimated that a full hold turnaround would require a minimum of 3 weeks of intensive cleaning. A delay of that scale would have severely impacted the vessel's laycan and commercial schedule.
To safeguard the charterparty timeline, Delta Maritime Agency was contracted to deliver a high-efficiency riding team solution. Our marine technical crew boarded the vessel directly at the discharging berth in Ploče to initiate an immediate, en-route hold preparation campaign.
Key Operational Metric:
Target: Coal-to-Grain Hold Conversion & Surface Renewal
Original Crew Estimate: 21 Days
Delta Riding Team Execution: 10 Days En Route
The Technical Solution: 10-Day Hold Preparation & Surface Renewal
Deploying a certified, round-the-clock riding team, Delta Maritime Agency completed the entire 7-hold structural preparation during the ocean transit in just 10 days—slashing the initial estimate by more than 50%.
Our systematic hold cleaning framework followed a rigorous 4-stage technical protocol:
- Targeted Alkaline Washdown: High-efficiency chemical wash applications designed to completely break down and wash away stubborn coal soot, heavy grease, and micro-particles from bulkheads and deckheads.
- High-Pressure Hydroblasting: Precision high-pressure waterjet blasting across shadow zones, structural framing segments, hatch covers, and upper hoppers.
- Freshwater Rinsing & Bilge Decontamination: Neutralizing corrosive marine salts and chemical residues, followed by complete bilge well cleaning and thorough drying to create an odor-free environment.
- Targeted Marine Paint Coating Renewal: Conducting close-up structural inspections during the final drying phase to identify localized rust appearances on hoppers and lower stool bulkheads. The team executed localized mechanical descaling and applied fresh, high-durability, food-grade compatible marine paint coatings to ensure full compliance with international grain standards.
The Result: First-Time Acceptance with Zero Remarks
The disciplined execution of our specialized riding crew yielded flawless results. Upon arrival at the Barcarena port roads in Brazil, the local independent surveyor conducted a thorough hold inspection.
All 7 cargo holds passed instantly with zero remarks, allowing the MV BELMONTE to proceed directly to the loading berth without losing a single commercial window.
