DNV GL is authorised by more than 130 flag administrations to carry out statutory certification on their behalf. Our international network of approval centres and more than 300 survey stations in over 100 countries make our services stand out from the rest.

Trusted by Maritime Administrations to certify on their behalf

Many Maritime Administrations put their trust in DNV GL – and have delegated the certification of ships according to IMO Conventions and Codes to us. In most cases, we certify DNV GL-classed vessels only, but in case of management system certification (ISM, ISPS and MLC 2006), our services are offered independently of the vessels’ class.

The degree of authorisation varies from administration to administration. In some cases, we have full authorisation and are in charge of the entire certification process – in other cases, the Maritime Administration handles part of the process, such as the issuance of full-term certificates. In both cases, DNV GL is a trusted, competent partner.

Statutory certification is essential throughout a vessel’s lifetime – from initial certification in connection with delivery to annual, intermediate and renewal surveys during its operational life. Statutory surveys are normally also required when the vessel changes flag or class.

So rely on DNV GL for efficient and timely execution of your statutory certification needs. We have the world’s largest network of experienced and qualified surveyors, and cooperate with owners and managers to plan surveys in line with the vessels’ operational schedules – ensuring cost efficiency.
