Trans-Atlantic Excellence: Cargo Hold Cleaning and Maintenance on MV N BONANZA
How Delta Maritime Agency’s specialized riding team prepared a massive dry bulk carrier for strict "grain clean" inspections in just 12 days during a challenging ocean passage.
The Challenge: A 12-Day Race Against Weather and Time
Performing comprehensive cargo hold cleaning during a trans-Atlantic Ocean passage is one of the most demanding tasks in bulk maritime logistics. Unpredictable weather conditions, rough seas, and tight schedules mean that relying solely on a ship’s crew can lead to high-risk delays or inspection failures.
For the bulk carrier MV "N BONANZA", the stakes were high:
- Vessel Type & Size: 7 Holds / 7 Hatches, DWT 76,596 mt, LOA 224.94 m, Beam 32.26 m.
- Holds Volume: 90,740 cubic meters.
- The Transition: Cleaning from a highly contaminating bulk coal cargo to a strict bulk grain cargo standard.
- The Timeline: A brief 12-day ocean crossing from Gibraltar anchorage to the loading port in Brazil.
Strategy and Mobilization at Gibraltar
To ensure zero operational downtime, Delta Maritime Agency mobilized an expert hold cleaning riding team. The team boarded the vessel at the Gibraltar anchorage during a scheduled crew change and provisioning stop.
Capitalizing on immediate anchorage time, the riding team instantly began high-altitude cleaning of the hatch coamings and upper portions of the holds before the vessel even began its cross-ocean voyage.
The 5-Step Professional Hold Preparation Workflow
Transitioning a vessel from coal to a pristine grain standard requires a methodical technical framework. Our team executed a precise 5-step hold preparation plan:
- Chemical Application: Applying specialized sodium hypochlorite solutions across all bulkheads and structural surfaces contaminated with coal dust.
- Chemical Washout: Thorough pressure washing to strip away the active chemicals and dissolved soot.
- High-Pressure (HP) Cleaning: Deploying heavy-duty high-pressure machinery to scour heavily encrusted and hard-to-reach structural areas.
- Freshwater (FW) Rinsing & Drying: A meticulous freshwater rinse of all 7 holds and hatches to prevent salt crystallization, followed by detailed bilge well cleaning and forced drying.
- Marine Hold Maintenance & Spot Painting: Treating upper parts of bulkheads, hoppers, and in-between frames. Our team scraped away minor rust, addressed burned or transferable stains, and performed spot painting to prevent subsequent cargo contamination.
Double Inspection Success in Brazil
Thanks to round-the-clock efforts by our certified riding team, the heavy-duty cleaning and maintenance of the holds, deck, and superstructure were completed right before the ship reached the pilot boarding ground.
The vessel achieved flawless, consecutive passes at both critical inspection milestones:
- First Pass: Before commencing navigation through the Amazon River.
- Second Pass: Upon arrival at the designated loading position in Itacoatira, Brazil.
Don't Risk Rejection—Partner with Professionals
A single cargo hold rejection can cost ship operators tens of thousands of dollars in port delays, off-hire time, and additional cleaning materials. Do not experiment with your business by over-relying on a fatigued ship's crew.
Delta Maritime Agency provides elite riding teams equipped for fast global mobilization, ensuring your vessel passes inspection as a simple and predictable formality.
