DNV supports you in ensuring safer mooring

We care deeply about maritime safety and are dedicated to contributing to safer and smarter mooring operations.

Services for newbuildings 

The new IMO guidelines MSC.1/Circ.1619, MSC.1/Circ.1620 and MSC.1/Circ.1175 include new requirements to be considered for newbuildings after 1 January 2024.

DNV, acting as a Recognized Organization (RO) promoting safe mooring and striving to assist our customers, is currently evaluating whether we will develop voluntary class notations which take into account the new IMO requirements following the amended SOLAS Regulation II-1/3-8. We will soon decide if there is a possible need for such a notation.

In addition, DNV will continue to approve the necessary documentation according to DNV Rules.

Services for ships in operation

As a classification society, DNV may offer a voluntary Statement of Compliance with MSC.1/Circ.1620 “Guidelines for inspection and maintenance of mooring equipment including lines”. Please see our Safe mooring guidance paper for further information. Due to ongoing work with the interpretation of the MSC guideline and the amended SOLAS Regulation II-1/3-8, the guidance is a living document, and you should always check under the link above if there is an updated version available.
