About

Independent figures

Heru measures what is in the tanks and records what is in the holds, for whichever party appoints us.

We have no links to any bunker supplier. The buyer, the seller and the charterer read the same figures, whoever appointed us.

Surveys are carried out at berth and at anchorage in Antwerp, Rotterdam, Amsterdam, Zeebrugge, Ghent and Ostend, from a base on the Belgian coast.
