C-004 Helicopter deck on offshore installations (Rev. 1, September 2004)

This NORSOK standard defines the basic requirements for design, arrangement and engineering of helicopter decks on offshore installations in the petroleum industry. This NORSOK standard covers fixed type installations, normally unmanned installations, floating installations, production, drilling and storage vessels.

This NORSOK standard is based on practical experiences accumulated from helicopter operations on the Norwegian continental shelf. Relevant information has been provided by oil companies, helicopter operators and The Foundation for Scientific and Industrial Research at The Norwegian University of Science and Technology (SINTEF). A joint industry project on helideck safety was completed in January 2000. The main conclusions and recommendations are included in this NORSOK standard.

This NORSOK standard focuses on a rational selection of design criteria and other measures, to increase safety and flight regularity in connection with offshore helicopter deck operations.

The requirements in this NORSOK standard are generally defined as functional requirements. Certain technical requirements are, however, specified when deemed necessary.
