Herron Inspection

Services

Five inspection services for cargo and fuel, in the ports of Limón, Moín and Caldera. Every service ends with a written report.

1

Draft Survey

We read the vessel's drafts before and after loading or discharge to calculate the cargo quantity moved.

An inspector reads the draft marks forward, midships and aft on both sides of the hull. We then account for ballast, fresh water and fuel on board and work through the vessel's tables to calculate the weight of cargo loaded or discharged. It is the usual way to measure bulk cargo when there is no shore scale.

Bunker Survey

We measure the fuel on board before and after bunkering to confirm the quantity delivered.

We gauge the vessel's fuel tanks before and after bunkering, correct the readings for trim, list and temperature, and compare the result with the supplier's delivery note. Any difference is recorded in the report.

Tally Control Cargo

We count and record cargo units as they are loaded or discharged.

We count each unit, bundle, coil or bag as it is loaded or discharged and note its marks and visible condition. At the end of the operation, the tally is checked against the cargo documents.

Loss Control & Damage Reports

We document shortages and damage to cargo with measurements and photos, so claims have evidence behind them.

We attend the operation to catch shortages and damage as they happen. We record the condition of the cargo and its packaging with measurements and photos, and note the cause when it can be established, so you have evidence for a claim.
