The Suez Canal is run by the Suez Canal authority, who has their own tonnage regulation. The Suez Canal special tonnage certificate is needed for transiting the Canal, and contains values of Gross Register Ton (GRT) and Net Register Ton (NRT).
The certificate is a requirement by the Suez Canal authority for calculating the “transit fees” when using the Canal.
A statutory certificate issued by DNV is a document that has a good reputation in the industry.
This certificate has no expiry date except when there are alterations / conversions / change of flag. DNV carries out the required calculations and surveys and issues the new certificate to customers according to the requirements.
The owner will receive the certificate before delivery, and the certificate will be updated if a conversion takes place, or at the owner's request.
