Reversing Heavy Back-to-Back Coal Contamination on MV Medi Newport

Carrying a single dirty cargo like coal requires exhaustive cleaning protocols before a bulk carrier can load food-grade agricultural commodities. However, when a vessel carries two bulk coal cargoes in a row, the contamination compounds dramatically. Because proper cleanups are rarely performed between consecutive identical "dirty" voyages, coal dust, oily carbon films, and tightly packed residues cake into structural corners, frame intersections, and bulkheads. In these scenarios, standard ship crew washing is rarely enough, and achieving a strict grain clean standard can seem nearly impossible.

This was the exact challenge onboard the Kamsarmax bulk carrier MV "MEDI NEWPORT" (7 Holds / 7 Hatches, 81,756 DWT). After completing consecutive coal runs, the vessel was fixed to load bulk corn in Itaqui, Brazil. To eliminate the threat of a costly hold rejection at the loading port, Delta Maritime Agency deployed a specialized mobile riding team to handle full-scale hold restoration, derusting, and deck/superstructure technical maintenance en route during a trans-Atlantic passage from Wedel, Germany.

When a ship transitions from severe carbon contamination to grain-clean status, the inspection parameters are uncompromising. Attending commercial surveyors perform highly detailed visual checks and manual glove tests on all vertical surfaces, including the highest under-deck areas, hopper framing lines, and hatch structures.

Even after heavy washing, back-to-back coal runs leave deep-seated, transferable stains and reveal underlying localized rust patches that harbor hidden cargo dust. If these transferable stains or loose flakes remain, the vessel fails its survey instantly, resulting in immediate off-hire status and compounding demurrage fees.

To combat the dense layer of carbon and structural corrosion during the trans-Atlantic passage, our certified riding team implemented a rigorous, industrial-grade cleaning and preservation workflow:

By the completion of the Atlantic ocean passage, the holds of the MV Medi Newport were completely transformed, looking as though the vessel had just emerged pristine from a shipyard dry dock.

Upon arrival in Itaqui, Brazil, discerning surveyors boarded the vessel and subjected even the hardest-to-reach brackets and overhead structures to strenuous physical glove tests. Thanks to the meticulous work of our mobile team, all holds were accepted immediately without a single remark or deficiency. The shipowners successfully protected their charter agreement and commenced loading bulk corn right on schedule.

Don't risk your dry bulk commercial operations or gamble with expensive port delays by relying solely on an overworked ship’s crew.
