The INSB Rules & Regulations derive from principles of naval architecture, marine engineering IMO conventional requirements, MSC circulars, IACS unified interpretations, in service feedback and research findings.
Design and Construction requirements, scope of tests and surveys are defined by the Rules for Ship Classification and Construction.
Classification Surveys are based on a regular five-year cycle including Annual Surveys, an Intermediate Survey and a comprehensive Special Survey including dry docking or underwater inspection in lieu of dry docking twice in a five year period.
The society’s Rules and Regulations for the Construction and Classification of Ships are systematically developed, continually upgraded through a structure of specialized technical committees.
In addition the society has developed Guidance & Instruction Manuals for marine surveys for compliance with classification and various statutory requirements.
