Statement of Reasons
This notice exempts a class of ship from compliance with specified requirements in Maritime Rules, Part 40E Design, Construction and Equipment – Sailing Ships made under the Maritime Transport Act 1994 (see section 40AA(1)(b) of the MTA).
General provisions relating to the exemption
The exemption in clause 4 of this notice relates to rule 40E.21(5), which sets requirements for portlights’ size, shape, and the method by which they must be secured to ensure they do not affect the vessel’s hull integrity or watertightness.
In respect of the requirements specified in maritime rule 40E.21(5), the exemption will apply to the class of ship described in clause 4(2) of this notice.
The exemption in clause 4 is subject to the conditions set out in clause 5.
This exemption comes into force on 14 December 2022 and will expire in accordance with the provisions of clause 6.
Director may grant exemptions from maritime rules
The Director of Maritime New Zealand, being satisfied as to the matters set out in section 40AA of the Act, thinks it appropriate to grant the class exemption in accordance with the specified conditions because:
- Portlights of different sizes and shapes that are secured by alternative methods determined by a Recognised Surveyor, and in accordance with accepted regulatory/standardisation bodies, fulfils the Rules objectives.
The Director is further satisfied that the exemption meets the criteria in section 40AA(2) of the Act and that the conditions are appropriate as:
- No international convention requirements: the requirements in the rule are purely domestic requirements that do not implement any international conventions. Therefore granting the exemption will not breach New Zealand’s obligations under any convention (section 40AA(2)(a)).
- One of the criteria in section 40AA(2)(b) applies:
- (ii) the manner in which the requirement is sought to be fulfilled is as effective as actual compliance with the requirement:
- Portlights meeting the standards published by accepted regulatory/standardisation bodies is considered to be as effective as compliance with the existing rule-based requirements;
- Recognised Surveyors (Design Approval) have the appropriate skills to determine if an alternative method of securing a portlight, or an alternative size and shape of portlight is appropriate.
- Risk of harm to the marine environment: there are no specific or unique environmental risks related to portlights on the impacted sailing ships. Therefore the granting of the exemption will not significantly increase risk of harm to the marine environment (section 40AA(2)(c)).
- Risk to safety: the alternative approaches covered in the conditions of the exemption meet the intent of the rules and provide assurance that portlights won’t impact the hull integrity or water tightness of the ship. Therefore granting the exemption will not significantly increase risk to safety (section 40AA(2)(d)).
