• (5) If a ship at the time when an IOPP Certificate expires is not in a port in which it is to be surveyed, the Minister may extend the period of validity of the Certificate but such extension shall be granted only for the purpose of allowing the ship to complete its voyage to the port in which it is to be surveyed, and then only in cases where it appears proper and reasonable to do so. An IOPP Certificate shall not be extended for a period longer than 3 months, and a ship to which an extension is granted shall not, on its arrival in the port in which it is to be surveyed, be entitled by virtue of such extension to leave that port without having a new IOPP Certificate. When the renewal survey is completed, the new IOPP Certificate shall be valid to a date not exceeding 5 years from the date of expiry of the existing IOPP Certificate before the extension was granted.

• (6) An IOPP Certificate issued to a ship engaged on short voyages which has not been extended under the foregoing provisions of this Regulation may be extended by the Minister for a period of up to one month from the date of expiry stated on it. When the renewal survey is completed, the new Certificate shall be valid to a date not exceeding 5 years from the date of expiry of the existing Certificate before the extension was granted.

• (7) In such special circumstances as the Minister may determine, a new IOPP Certificate need not be dated from the date of expiry of the existing IOPP Certificate as required by paragraph (2)(b), (5) or (6). In these special circumstances, the new IOPP Certificate shall be valid to a date not exceeding 5 years from the date of completion of the renewal survey.

• (8) If an annual or intermediate survey is completed before the period specified in Regulation 6, then:

• (a) the anniversary date shown on the IOPP Certificate shall be amended by endorsement to a date which shall not be more than 3 months later than the date on which the survey was completed;

• (b) the subsequent annual or intermediate survey required by Regulation 6(1) shall be completed at the intervals prescribed by that Regulation using the new anniversary date;

• (c) the expiry date may remain unchanged provided one or more annual or intermediate surveys, as appropriate, are carried out so that the maximum intervals between the surveys prescribed by Regulation 6(1) are not exceeded.

• (9) An IOPP Certificate issued under Regulation 7 or 8 shall cease to be valid in any of the following cases:

• (a) if the relevant surveys are not completed within the periods specified under Regulation 6(1);

• (c) if the ship transfers to the flag of another state.

Port State Control on operational requirements

• (2) If, consequent on an inspection of a ship by an officer pursuant to his or her powers under paragraph (1), the officer confirms that the master or crew are not familiar with the procedures referred to in that paragraph, the Minister shall take such steps (which he or she is hereby empowered to take) as will ensure that the ship shall not sail from the port until such time as the master or crew or, as the case may be, both the master and crew have become familiar with those procedures.

• (3) So much of the procedures specified in Article 5 of the MARPOL Convention as are appropriate shall apply, with any necessary modifications, for the purposes of this Regulation.

• (4) Nothing in this Regulation shall operate to derogate from the powers and duties of the Minister or any other person under the Act or any Regulations made thereunder.

HW = 1.0 m, when YB = 0

HW = BB/50 but not greater than 0.4m, when YB is greater than BB/5 or 11.5m, whichever is less

“HW” is to be measured upwards from the midship flat bottom line. In the turn of the bilge area and at locations without a clearly defined turn of the bilge, HW is to be measured from a line parallel to the midship flat bottom, as shown for distance “h” in Figure 1, which is set out in Schedule 4;

for YB values outboard BB/5 or 11.5m, whichever is less, HW is to be linearly interpolated;
