Precision and readiness for the next cargo.
At UPRIVER Marine, we assist shipowners, operators, and charterers during tank cleaning operations—ensuring that tanks are properly prepared, inspected, and ready for high-specification cargoes such as vegetable oils, biofuels, or chemicals.
Whether at anchorage, berth, or during turnaround between voyages, we provide:
– Operational support and supervision throughout the tank cleaning process
– Visual inspection before and after cleaning
– Tank approval assistance: liaising with loading terminals, surveyors, or receivers
– Monitoring of residues and verification of gas-free status
– Pre-loading readiness checks in line with cargo specs or charter party clauses
– Documentation review and records of previous cargoes, cleaning logs, and MSDS
We act as a link between the crew, terminal, and client—ensuring transparency, efficiency, and full compliance with commercial and safety requirements.
