Complying with MARPOL annex II requirements for NLS certificate
The International Pollution Prevention Certificate for the carriage of Noxious Liquid Substances in Bulk is mandatory for ships carrying noxious liquid substances according to MARPOL 73/78 Annex II when the ship is not provided with a Chemical Code Certificate.
The NLS certificate is required when carrying such substances in bulk. The statutory certificate issued by DNV is a document that has a good reputation in the industry. In port state control statistics issued by the Paris MoU 2007, DNV achieved the top ranking among the classification societies.
An International Pollution Prevention Certificate for the carriage of Noxious Liquid Substances in Bulk is to be issued after the completion of an initial or renewal survey. Vessels in DNV Class that fly a flag which authorises DNV to issue the certificate on its behalf will have a five-year certificate issued by DNV on behalf of the Flag Administration.
To maintain a valid certificate, an annual survey will be carried out each year and an intermediate survey will be carried out after 2.5 years, and the certificate will be endorsed.
The certificate will upon expiry be renewed following a renewal survey.
