Rules for High Speed, Light Craft and Naval Surface Craft, January 20 Pt.5 Ch.4 Sec. Page 5 SECTION GENERAL REGULATIONS A. Classification A 00 Application 0 The rules in this chapter apply to craft carrying workers between shore and offshore installations and similar types of transportation. Guidance note: The rules in this chapter are different from the rules for the class notation Passenger because workers are considered as more professional and fit than ordinary passengers. It is assumed that workers are trained in safety aspects and are familiar with the subject type of sea transportation. The notation Crew is based on the same level of safety as specified by a standard reported to IMO for crew boats up to 00 gross tons with equivalent arrangement accepted under Regulation 5 of Chapter I of SOLAS, although this notation is applicable to high speed and light craft in accordance with the IMO Code specified in 03. National Authorities may have additional requirements for crew transportation. ---e-n-d---of---g-u-i-d-a-n-c-e---n-o-t-e--- 02 The rules do not apply to craft carrying ordinary passengers as defined under the class notation Passenger. 03 Craft of 500 gross tonnage and upwards or craft carrying more than 50 workers shall comply with the requirements for cargo craft in accordance with the International Code of Safety for High-Speed Craft (HSC Code). 04 The craft is to comply with the maximum speed requirement of the HSC code: = maximum permissible displacement (m 3 ) v = maximum speed at displacement (m/sec). v 3.7 0, 667 A 200 Type notations 20 High speed and light craft built in compliance with the main class requirements of the Rules Pt., Pt.2, Pt.3 and Pt.4, with the modifications and additional requirements given in this Chapter, may be assigned the type and service notation: Crew 202 Craft intended for carriage of cargo in addition to the crew transportation shall comply with Ch.3 and will be assigned additional class notations denoting both service categories e.g.: A HSLC R Cargo A Crew 203 Craft having special equipment or systems found to satisfy relevant requirements in Pt.6 will be given corresponding additional notation, i.e. E0, NAUT etc. A 300 Service area restriction notations 30 Craft with the type notation Crew will be given one of the following service restrictions R, R2, R3, R4 or R5. 302 For the service restrictions R4 and R5 modified requirements of this chapter may be considered. A 400 Operation limitation 40 Limitations of speed versus sea state (significant wave height) will be given corresponding to the design vertical acceleration at longitudinal centre of gravity LCG. 402 The class notation allows for operational restrictions based on.5 g vertical acceleration at LCG compared with maximum.0 g for the notation Passenger. 403 The approved maximum number of persons for which the craft is designed and equipped for normal operation at sea, will be stated in the Appendix to the Classification Certificate.
