Sec. 167.15-30  Drydock examination, internal structural examination, and underwater survey intervals.

    (a) Except as provided for in paragraphs (b) through (e) of this 
section, each vessel must undergo drydock and internal structural 
examinations as follows:
    (1) If your vessel operates in saltwater, it must undergo two 
drydock examinations and two internal structural examinations within any 
5-year period unless it has been approved to undergo an underwater 
survey (UWILD) under Sec. 167.15-33 of this part. No more than three 
years may elapse between any two examinations.
    (2) If your vessel operated in fresh water at least 50 percent of 
the time since your last drydocking, it must undergo a dry dock and 
internal structural examination at intervals not to exceed 5 years 
unless it has been approved to undergo an underwater survey (UWILD) 
under Sec. 167.15-33 of this part.
    (b) Vessels with wooden hulls must undergo two drydock and two 
internal structural examinations within any five year period regardless 
of the type of water in which they operate. No more than three years may 
elapse between any two examinations.
    (c) If, during an internal structural examination damage or 
deterioration to the hull plating or structural members is discovered, 
the Officer in Charge, Marine Inspection, may require the vessel to be 
drydocked or otherwise taken out of service to further assess the extent 
of the damage and to effect permanent repairs.
    (d) Each vessel which has not met with the applicable examination 
schedules in paragraphs (a) through (c) of this section because it is on 
a voyage, must undergo the required examinations upon completion of the 
voyage.
    (e) The Commandant (G-MOC) may authorize extensions to the 
examination intervals specified in paragraphs (a) and (b) of this 
section.
