Cargo Grade Change

Cleaning & Conversion During Running Time

Cargo Grade Change Without Stopping Vessel Operations

Traditional cargo grade change often forces vessels to remain idle at port for several days, leading to port service charges, lost charter time, and operational inefficiencies. Our onboard service model eliminates these challenges.
We perform cargo grade change activities while the vessel is sailing, whether loaded or empty, ensuring:
This method allows vessels to continue earning while essential work is completed safely and efficiently.

Frequently Asked Questions

Cargo grade change services involve cleaning, preparation, and conversion of cargo holds or tanks when a vessel switches from one cargo type to another. This ensures the cargo spaces meet required cleanliness and compliance standards for the next cargo.

Yes. Cargo grade change can be carried out onboard while the vessel is sailing, at anchorage, or during short port calls. This approach avoids long port stays and allows vessels to remain operational during the process.

Performing cargo grade change during sailing reduces port waiting time, lowers berth and port service costs, and ensures faster readiness for the next cargo. It allows vessels to continue earning while essential cleaning and conversion work is completed.

Cargo grade change typically includes hold cleaning, demucking, and DPP–CPP conversions. These services work together to remove residues, contaminants, sludge, and traces of previous cargo to meet inspection and cargo requirements.

Demucking involves the removal of sludge, sediments, and stubborn residues from cargo spaces. It is essential when standard cleaning is not sufficient to meet cleanliness standards required for sensitive or higher-grade cargoes.

DPP–CPP conversion refers to converting cargo tanks from Dirty Petroleum Products to Clean Petroleum Products. This process ensures tanks meet the strict cleanliness and compliance requirements needed for carrying refined or sensitive petroleum cargoes.

Cargo grade change services are commonly required by bulk carriers, tankers, and general cargo vessels transitioning between different cargo types. The scope of work depends on the previous cargo, next cargo, and inspection standards.

Yes. Cargo grade change services are available near major shipping routes such as the Strait of Gibraltar, including Gibraltar and Algeciras. This allows quick mobilization and efficient execution while vessels continue trading.

Proper cargo grade change ensures cargo spaces meet inspection standards on the first attempt. Clean and compliant holds or tanks reduce the risk of inspection failure, re-cleaning, cargo rejection, and schedule delays.

Ship operators can arrange cargo grade change services based on vessel schedule, cargo type, and location. Early planning allows cleaning and conversion work to be completed efficiently without disrupting commercial operations.
