General

Since the class notations applicable to drilling vessels are now covered by DNV Offshore Service Specification DNV-OSS-101, Sec.6 “Drilling Vessels” of the previous issue of this chapter has been removed. The revised chapter, including other amendments previously listed in Pt.0 Ch.1 Sec.3, has therefore been reprinted, and the July 2005 issue supersedes the January 2004 issue.

This chapter is valid until superseded by a revised chapter. Supplements will not be issued except for an updated list of minor amendments and corrections presented in Pt.0 Ch.1 Sec.3. Pt.0 Ch.1 is normally revised in January and July each year.

Revised chapters will be forwarded to all subscribers to the rules. Buyers of reprints are advised to check the updated list of rule chapters printed Pt.0 Ch.1 Sec.1 to ensure that the chapter is current.
