covered by this Annex the master or owner of the ship shall report at the earliest opportunity to the Administration, the recognized organization or the nominated surveyor
responsible for issuing the relevant Certificate, who shall cause investigations to be initiated to determine whether a survey as required by paragraph 1 of this regulation is
necessary. If the ship is in a port of another Party, the master or owner shall also report immediately to the appropriate authorities of the Port State and the nominated surveyor
necessary. If the ship is in a port of another Party, the master or owner shall also report immediately to the appropriate authorities of the Port State and the nominated surveyor
or recognized organization shall ascertain that such report has been made.
Regulation 5 Issue or Endorsement of Certificate
1 An international Sewage Pollution Prevention Certificate shall be issued, after an initial or renewal survey in accordance with the provisions of regulation 4 of this Annex to any
ship which is engaged in voyages to ports or offshore terminals under the jurisdiction of other Parties to the Convention. In the case of existing ships this requirement shall apply
five years after the date of entry into force of this Annex.

1 An International Sewage Pollution Prevention Certificate shall be issued for a period specified by the Administration which shall not exceed five years.
2 .1 Notwithstanding the requirements of paragraph 1 of this regulation, when the renewal survey is completed within three months before 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 date of expiry of the existing
Certificate.
2 .2 When the renewal survey is completed after 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 date of expiry of the existing Certificate.
2 .3 When the renewal survey is completed more than three months before 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 date of completion of the renewal survey.
3 If a Certificate is issued for a period of less than five years, the Administration may extend the validity of the Certificate beyond the expiry date to the maximum period
specified in paragraph 1 of this regulation.
4 If a renewal survey has been completed and a new Certificate cannot be issued or placed on board the ship before the expiry date of the existing Certificate, the person or
organization authorized by the Administration may endorse the existing Certificate and such a Certificate shall be accepted as valid for a further period which shall not exceed five
months from the expiry date.
5 If a ship at the time when a Certificate expires is not in a port in which it is to be surveyed, the Administration may extend the period of validity of the Certificate but this
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. No Certificate shall be extended for a period longer than three 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 Certificate. When the renewal survey is completed, the new
Certificate shall be valid to a date not exceeding five years from the date of expiry of the existing Certificate before the extension was granted.
6 A 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 Administration
for a period of grace 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
five years from the date of expiry of the existing Certificate before the extension was granted.
7 In special circumstances, as determined by the Administration, a new Certificate need not be dated from the date of expiry of the existing Certificate as required by paragraph
7 In special circumstances, as determined by the Administration, a new Certificate need not be dated from the date of expiry of the existing Certificate as required by paragraph
2.2, 5 or 6 of this regulation. In these special circumstances, the new Certificate shall be valid to a date not exceeding five years from the date of completion of the renewal
survey.
8 A Certificate issued under regulation 5 or 6 of this Annex shall cease to be valid in either of the following cases:
.1 if the relevant surveys are not completed within the periods specified under regulation 4.1 of this Annex; or
.2 upon transfer of the ship to the flag of another State. A new Certificate shall only be issued when the Government issuing the new Certificate is fully satisfied that the
ship is in compliance with the requirements of regulations 4.7 and 4.8 of this Annex. In the case of a transfer between Parties, if requested within 3 months after the
transfer has taken place, the Government of the Party whose flag the ship was formerly entitled to fly shall, as soon as possible, transmit to the Administration copies
of the Certificate carried by the ship before the transfer and, if available, copies of the relevant survey reports.

Reg.1.1 IACS' unified interpretation MPC91 (Sept 2007) Annex IV of MARPOL 73/78:
"A similar stage of construction" means the stage at which:
(a) construction identifiable with a specific ship begins; and
(b) assembly of that ship has commenced comprising at least 50 tonnes or one per cent of the estimated mass of all structural material, whichever is less.
________
Note:
This UI is to be uniformly implemented by IACS Societies from 1 October 2007.
This UI is to be uniformly implemented by IACS Societies from 1 October 2007.
Above interpretation is confirmed as Annex 8 from the report of the Marine Environment Protection Committee in April 2008.
Technical Background for this IACS UI and IACS UI MPC90 (Sept. 2007):
MARPOL Annex I and Annex IV contain the phrase "similar stage of construction" in the numerous definitions of "ship delivered" which is used to determine the application of
regulations in these Annexes.
The phrase "similar stage of construction" is not defined in Annex I and Annex IV, as it is in MARPOL Annex II and Annex VI as shown below:
"A similar stage of construction" means the stage at which:
(a) construction identifiable with a specific ship begins; and
(b) assembly of that ship has commenced comprising at least 50 tonnes or one per cent of the estimated mass of all structural material, whichever is less.
To provide for consistency of MARPOL Annexes I and IV with MARPOL Annexes II and VI, the definition of "similar stage of construction" in MARPOL Annexes II and VI is extended
to apply to MARPOL Annexes I and IV.

Reg.9.1.1 (ref. the footnote to regulation 9.1.1, referring to resolution MEPC.2(VI), and the operative paragraph 2(a) of resolution MEPC.159(55), which supersedes resolution
MEPC.2(VI), and paragraph 1.3 in the Annex thereto): IACS Unified Interpretation MPC88 (Feb 2007) Annex IV of MARPOL 73/78 Regulation 9.1.1:
For application of resolution MEPC.159(55), the phrase “installed on board a ship on or after 1 January 2010” shall be interpreted as follows:
(a) For new ships, installations on board ships the keels of which are laid or which are at a similar stage of construction on or after 1 January 2010.
(b) For existing ships, new installations with a contractual delivery date to the ship on or after 1 January 2010 or, in the absence of a contractual delivery date, the actual
delivery of the equipment to the ship on or after 1 January 2010.

Reg.10.1 MEPC 55, unified interpretation, October 2006, and IACS Unified Interpretation MPC86 (June 2006) (Corr.1 Oct. 2007; Note No.2) Annex IV of MARPOL 73/78
Regulation 10.1 as amended by Resolution MEPC.115(51):
All ships subject to Annex IV, irrespective of their size and of the presence of a sewage treatment plant or sewage holding tank, shall be provided with a pipeline and the relevant
shore connection flange for discharging sewage to port sewage treatment facility.
________
Note:
1. This UI is to be uniformly implemented by IACS Societies for ships contracted for construction on or after 1 January 2007.
2. The “contracted for construction” date means the date on which the contract to build the vessel is signed between the prospective owner and the shipbuilder. For further
details regarding the date of “contract for construction”, refer to IACS Procedural Requirement (PR) No. 29.
Technical background for IACS UI MPC86 (June 2006):
This UI has been developed to assure the provision of a shore connection for sewage discharge for ships of any size, irrespective of the presence of a sewage treatment plant or
sewage holding tank.
A standard discharge connection is required to be provided to ensure there is a capability to discharge sewage ashore in cases when
- a sewage treatment plant is not available due to malfunction or maintenance and discharge of sewage into the sea is not possible or it is forbidden by local law,or
- a holding tank needs to be emptied for tank cleaning and/or inspection purposes, or
- in the event of a prolonged stay in port where the capacity of the holding tank is exceeded.

material covered by the survey, without the sanction of the Administration, except the direct replacement of such equipment and fittings.
9 Whenever an accident occurs to a ship or a defect is discovered which substantially affects the integrity of the ship or the efficiency or completeness of its equipment
covered by this Annex the master or owner of the ship shall report at the earliest opportunity to the Administration, the recognized organization or the nominated surveyor
responsible for issuing the relevant Certificate, who shall cause investigations to be initiated to determine whether a survey as required by paragraph 1 of this regulation is
necessary. If the ship is in a port of another Party, the master or owner shall also report immediately to the appropriate authorities of the Port State and the nominated surveyor
necessary. If the ship is in a port of another Party, the master or owner shall also report immediately to the appropriate authorities of the Port State and the nominated surveyor
or recognized organization shall ascertain that such report has been made.
Regulation 5 Issue or Endorsement of Certificate
1 An international Sewage Pollution Prevention Certificate shall be issued, after an initial or renewal survey in accordance with the provisions of regulation 4 of this Annex to any
ship which is engaged in voyages to ports or offshore terminals under the jurisdiction of other Parties to the Convention. In the case of existing ships this requirement shall apply
five years after the date of entry into force of this Annex.

1 An International Sewage Pollution Prevention Certificate shall be issued for a period specified by the Administration which shall not exceed five years.
2 .1 Notwithstanding the requirements of paragraph 1 of this regulation, when the renewal survey is completed within three months before 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 date of expiry of the existing
Certificate.
2 .2 When the renewal survey is completed after 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 date of expiry of the existing Certificate.
2 .3 When the renewal survey is completed more than three months before 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 date of completion of the renewal survey.
3 If a Certificate is issued for a period of less than five years, the Administration may extend the validity of the Certificate beyond the expiry date to the maximum period
specified in paragraph 1 of this regulation.
4 If a renewal survey has been completed and a new Certificate cannot be issued or placed on board the ship before the expiry date of the existing Certificate, the person or
organization authorized by the Administration may endorse the existing Certificate and such a Certificate shall be accepted as valid for a further period which shall not exceed five
months from the expiry date.
5 If a ship at the time when a Certificate expires is not in a port in which it is to be surveyed, the Administration may extend the period of validity of the Certificate but this
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. No Certificate shall be extended for a period longer than three 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 Certificate. When the renewal survey is completed, the new
Certificate shall be valid to a date not exceeding five years from the date of expiry of the existing Certificate before the extension was granted.
6 A 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 Administration
for a period of grace 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
five years from the date of expiry of the existing Certificate before the extension was granted.

This UI is to be uniformly implemented by IACS Societies from 1 October 2007.
Above interpretation is confirmed as Annex 8 from the report of the Marine Environment Protection Committee in April 2008.
Technical Background for this IACS UI and IACS UI MPC90 (Sept. 2007):
MARPOL Annex I and Annex IV contain the phrase "similar stage of construction" in the numerous definitions of "ship delivered" which is used to determine the application of
regulations in these Annexes.
The phrase "similar stage of construction" is not defined in Annex I and Annex IV, as it is in MARPOL Annex II and Annex VI as shown below:
"A similar stage of construction" means the stage at which:
(a) construction identifiable with a specific ship begins; and
(b) assembly of that ship has commenced comprising at least 50 tonnes or one per cent of the estimated mass of all structural material, whichever is less.
To provide for consistency of MARPOL Annexes I and IV with MARPOL Annexes II and VI, the definition of "similar stage of construction" in MARPOL Annexes II and VI is extended
to apply to MARPOL Annexes I and IV.

Reg.9.1.1 (ref. the footnote to regulation 9.1.1, referring to resolution MEPC.2(VI), and the operative paragraph 2(a) of resolution MEPC.159(55), which supersedes resolution
MEPC.2(VI), and paragraph 1.3 in the Annex thereto): IACS Unified Interpretation MPC88 (Feb 2007) Annex IV of MARPOL 73/78 Regulation 9.1.1:
For application of resolution MEPC.159(55), the phrase “installed on board a ship on or after 1 January 2010” shall be interpreted as follows:
(a) For new ships, installations on board ships the keels of which are laid or which are at a similar stage of construction on or after 1 January 2010.
(b) For existing ships, new installations with a contractual delivery date to the ship on or after 1 January 2010 or, in the absence of a contractual delivery date, the actual
delivery of the equipment to the ship on or after 1 January 2010.

1. This UI is to be uniformly implemented by IACS Societies for ships contracted for construction on or after 1 January 2007.
2. The “contracted for construction” date means the date on which the contract to build the vessel is signed between the prospective owner and the shipbuilder. For further
details regarding the date of “contract for construction”, refer to IACS Procedural Requirement (PR) No. 29.
Technical background for IACS UI MPC86 (June 2006):
This UI has been developed to assure the provision of a shore connection for sewage discharge for ships of any size, irrespective of the presence of a sewage treatment plant or
sewage holding tank.
A standard discharge connection is required to be provided to ensure there is a capability to discharge sewage ashore in cases when
- a sewage treatment plant is not available due to malfunction or maintenance and discharge of sewage into the sea is not possible or it is forbidden by local law,or
- a holding tank needs to be emptied for tank cleaning and/or inspection purposes, or
- in the event of a prolonged stay in port where the capacity of the holding tank is exceeded.
