Petroleum Cargo Inspection

Independent quantity and quality surveying at load and discharge.

Numbered storage tanks with access ladders and roof railings

What is petroleum cargo inspection?

Petroleum cargo inspection is the independent measurement and sampling of oil at each custody transfer. Inspectors gauge shore and ship tanks, take representative samples, check lines and seals, and reconcile the quantities against bills of lading and terminal records, so buyer and seller work from one verified figure.

The Jansma approach to inspection services

Our in-house inspection team, complemented by nominated third-party surveyors, handles every custody transfer across our network. We gauge tanks, witness sampling, seal lines and reconcile figures against BL and terminal records, so when a dispute arises, the evidence is already there.
