§ 125.100 Applicability.
(a) Except as provided by paragraph (c) of this section, this subchapter applies to each offshore supply vessel (OSV) of United States flag contracted for, or the keel of which was laid, on or after March 15, 1996.
(b) Each OSV contracted for, or the keel of which was laid, before March 15, 1996, must be constructed and inspected to comply with—
(1) The regulations in effect until March 15, 1996 (46
CFR subchapter I or subchapter T, as appropriate), as they existed at the time of construction; or
(2) The regulations in this subchapter.
(c) Each OSV permitted grandfathering under paragraph (b)(1) of this section must complete construction and have a Certificate of Inspection by March 16, 1998.
(d) Certain regulations in this subchapter apply only to limited categories of OSVs. Specific statements of applicability appear at the beginnings of those regulations.
(e) As used in this subchapter, the term “vessels contracted for” refers not only to the contracting for the construction of a vessel, but also to the contracting for a major alteration to a vessel, the contracting for the conversion of a vessel to an offshore supply vessel or liftboat, and the changing of service or route of a vessel if such changing increases or modifies the general requirements for the vessel or increases the hazards to which it might be subjected.
Note: Navigation and Vessel Inspection Circular 8–91, “Initial and Subsequent Inspection of Uncertificated Existing Offshore Supply Vessels, Including Liftboats”, contains guidance on how to apply the regulations in 46 CFR subchapters I and T to OSVs.
