Draft Survey & Tank gauging (Bunker survey)

Draft Survey

A draft survey is a means of determining the weight of any materials being loaded into (or discharged from) a vessel. Our experienced and highly qualified professionals can conduct a draft survey on your behalf of clients and issue a draft survey report.

The vessel draft survey measures the displacement of the water both before and after the loading or unloading, with the resulting difference between the two displacements representing the weight of the cargo. Cotecna performs inspection according to approved international guidelines when determining the weight of the cargo and consider several key factors while carrying out surveys.

Our inspector can perform draft survey and protect client’s interests with long experience and expertise in this field. We issue a draft survey report containing all of the details obtained during the survey. You can use this report to verify quantity of the cargo.

Tank gauging (Bunker survey)

A bunker survey establishes the amount of bunker and lube oil onboard the vessel. These surveys are an important loss-prevention measure since documentation of bunker operations is required in the event of a dispute or claim.

Improper collection and distribution of bunker samples may risk the settlement of a subsequent claim in the event of a dispute. Our global network of third party marine inspectors have extensive experience conducting bunker surveys prior to and after time charter periods.
