                           TITLE 46--SHIPPING
 
    CHAPTER I--COAST GUARD, DEPARTMENT OF TRANSPORTATION (CONTINUED)
 
PART 125--GENERAL--Table of Contents
 
Sec. 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.
