Purpose and scope

These rules apply to ships, high speed, light craft and naval surface craft. The requirements are also applicable for relevant class notations.

The classification activities include certification of products as well as assessment of the arrangement and dynamics in a machinery plant built up of various products. 103 Certification normally includes design approval, inspection and testing of components and workshop testing of the assembled product. A product certificate is issued when the certification requirements are fulfilled. However, no unit is finally accepted before the shipboard testing is successfully completed.

Classification activities also include approval of machinery arrangement such as foundation, alignment, etc. and all relevant dynamics such as torsional vibration, engine vibration, etc. Survey of installation and shipboard testing also forms part of classification.
