The Norwegian Maritime Directorate or whoever is authorized by the Ministry of the Environment may in special cases grant exemptions pursuant to this Chapter for ships that are not covered by Section 23-2, second paragraph.

All ships that, pursuant to Section 23-2 second paragraph, shall comply with the provisions of this Subpart, shall be subject to the surveys specified as follows:

a) An intial survey before the ship is put into service or before the issue of the international certificate required pursuant to Section 23-12, and which shall include a complete survey of its structure, equipment, systems, fittings, arrangements and material. A renewal survey performed at intervals not exceeding five years, except where Section 23-13, second, fifth, sixth or seventh paragraphs of this Chapter apply.
b) An additional survey, which is either a general or a partial survey, as the circumstances require. The survey shall be performed following a repair resulting from the investigations laid down in the second sentence below, or whenever important repairs or renewals take place.

Whenever damage occurs to a ship or a defect is discovered which substantially affects the structural safety or efficiency or completeness of its equipment covered by this Chapter, the master or shipping company shall report at the earliest opportunity to the Norwegian Maritime Directorate’s closest station or recognized classification society. The Norwegian Maritime Directorate or the recognized classification society shall ensure the initiation of investigations to determine whether a survey pursuant to the first paragraph is necessary.

§ 23-12. Issue or endorsement of certificates
Following an initial or renewal survey in compliance with the provisions of Section 23-11, an international sewage pollution prevention certificate shall be issued.

Such a certificate shall be issued or endorsed by the Norwegian Maritime Directorate, or by a recognized classification society authorized to perform duties on behalf of the Directorate.

§ 23-13. Duration and validity of certificate 
The international sewage pollution prevention certificate shall be issued for a period which shall not exceed five yars.

Where the renewal survey is performed within a period of three months prior to the expiry date of the existing certificate, a new certificate shall be valid from the date of completion of the renewal survey to a date not exceeding five years from the expiry date of the existing certificate.

Where the renewal survey is completed following the expiry date of the existing certificate, the new certificate shall be valid from the date of completion of the renewal survey to a date not exceeding five years from the expiry date of the existing certificate.

Where the renewal survey is completed more than three months prior to the expiry date of the existing certifcate, the new certificate shall be valid from the date of completion of the renewal survey to a date not exceeding five years from the date of completion of the renewal survey.

If a certificate is issued for a period of less than five years, the Norwegian Maritime Directorate, or whoever is authorized by the Directorate, may extend the validity of the certificate beyond the expiry date of the longest period indicated in the first paragraph.

If a renewal survey is completed and a new certificate cannot be issued or placed on board the ship prior to the expiry date of the existing certificate, the Norwegian Maritime Directorate, or whoever is authorized by the Directorate, may endorse the existing certificate. Such a certificate shall be accepted as valid for an additional period, which shall not exceed five months from the expiry date.

If a ship, at the date of expiry of a certificate, is not present in a port in which it is to be surveyed, the Norwegian Maritime Directorate, or whoever is authorized by the Directorate, may extend the validity of the certificate. This extension shall be granted exclusively to allow the ship to complete its voyage to the port in which it is to be surveyed. A certificate shall not be extended for a period exceeding three months. 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 to leave that port without having obtained a new certificate. When the renewal survey is completed, the new certificate shall be valid to a date not exceeding five years from the expiry date of the existing certificate before the extension was granted.

A certificate issued to a ship engaged on short voyages, and which has not been extended pursuant to the above-mentioned provisions of this Section, may be extended by the Norwegian Maritime Directorate, or whoever is authorized by the Directorate. The extension is given up to one month from the expiry date stated on the certificate. When the renewal survey is completed, the new certificate shall be valid to a date not exceeding five years from the expiry date of the existing certificate before the extension was granted.

Under special circumstances, a certificate must not necessarily be dated from the expiry date of the existing certificate, as determined by the third, seventh and eighth paragraphs of this Section. In such cases the new certificate shall be valid to a date not exceeding five years from the date of completion of the renewal survey.

A certificate issued pursuant to Section 23-12, shall no longer be valid in the following cases:

a) if the relevant surveys have not been completed within the periods specified in Section 23-11, first paragraph, of this Chapter;

b) upon transfer of a ship to the flag of another Party to MARPOL 73/78, Annex VI.
