Welcome to the
Naval Ship Assurance Support Service

NSASS is an alliance of the UK MoD, BMT and Lloyd’s Register EMEA. NSASS was conceived to support the UK MoD in the development, and application of the Naval Ship Assurance Framework and provision of the Naval Authority Knowledge Management Office.

The Naval Ship Assurance Framework defines a framework for naval ship specifications, standards and assurance. Its core components are a General Naval Specification linked to a Naval Ship Code, Naval Classification and Key Naval Standards.

The Naval Authority Knowledge Management Office provides management of Naval Authority Certification information and secretarial support to Naval Authority meetings and liaison groups.

We are here to assist you in providing assurance for your project. This assistance ranges from information on what the Naval Ship Assurance Framework is about, to helping you apply it to your project and dealing with your queries and feedback.
