1 Introduction

  1.1 Following SOLAS regulation I/7, the Survey Guidelines under the Harmonized System of Survey and Certification (resolution A.997(25)) currently specify that inspection of a passenger ship's bottom, as required by SOLAS regulation I/7, should be carried out annually, with two inspections in dry-dock in any five-year periodfootnote. Where acceptable to the Administration, the minimum number of inspections in dry-dock of the outside of the bottom of a passenger ship (which is not a ro-ro passenger ship) in any five-year period may be reduced from two to one. In such cases, the interval between consecutive inspections in dry-dock shall not exceed 60 months.

  1.2 It is recognized that technological advances have been made in regard to corrosion resistant materials, quality, endurance and effectiveness of hull coatings, repair in water by means of protected environment such as temporary cofferdam, implementation of effective five-year maintenance regimes and also the effectiveness of in-water survey (IWS) technology overall.

  1.3 The following guidance has been developed to ensure that sound technical judgement is exercised by Administrations in a uniform manner, when allowing passenger ships to have an in-water survey in lieu of bottom inspection in dry-dock.

  1.4 The guidance for in-water survey is intended to be applied to passenger ships of 15 years of age or lessfootnote which are not ro-ro passenger ships. Some aspects of the guidance may also be useful in ascertaining suitability of any in-water inspection of passenger ships.
