ESI Discount

Conditions

At the end of each quarter the Port of Rotterdam Authority will determine which vessels are eligible for the ESI discount. Applicable condition: at the actual time of arrival (ATA) in Rotterdam the vessel must have an ESI score of 31 points or more.

The discount applies to each call in the quarter concerned, with a maximum of 20 calls per single ship per quarter. The discount will be doubled if the ship also has an individual ESI-NOx score of 31.0 or more. When the ESI score is adjusted by the International Association of Ports and Harbours (IAPH) to below 31.0 points, or the ship is granted the status ‘inactive’, all paid out ESI discounts need to be repaid within four weeks upon first request.

For questions about the calculation of the ESI score, please contact the ESI Office of the International Association of Ports and Harbours.

Automatic confirmation

The agency of the relevant vessels will automatically receive a confirmation after each quarter. Applying for the ESI discount to the Port of Rotterdam Authority is not required. The discount will be remitted to the relevant agency. The IAPH always keeps an up-to-date list of vessels that qualify for the ESI discount.
