context_page_description: The SFI Group System is the most widely used classification system for the maritime and offshore industry worldwide. It is an international standard, which provides a functional subdivision of technical and financial ship or rig information.
  SFI consists of a technical account structure covering all aspects of ship/rig specification, and it can be used as a basic standard for all systems in the shipping/offshore industry.
  More than 6000 SFI systems have been installed worldwide.
  SFI is used by shipping and offshore companies, shipyards, consultancies, software suppliers, authorities and classification societies.
context_section_description: The SFI Group System is built up as a 3-digit decimal classification system. The ship/rig is divided into 10 Primary Groups from 0 to 9. Only Primary Groups 1 to 8 are in use. The users may use Primary Groups 0 and 9 for classifying other main components that are not covered by the SFI standard.
  Each of the Primary Groups (1st digit) consists of 10 Groups (2nd digit) and each Group is divided further into 10 subgroups (3rd digit).
  The Primary Groups (1st digit) of SFI for Ships is described below.
