EXPLANATORY NOTE
(This note is not part of the Regulations)
These Regulations amend the Merchant Shipping (Control and Management of Ships’ Ballast Water
and Sediments) Regulations 2022 (S.I. 2022/737) (“the 2022 Regulations”), which implement the
International Convention for the Control and Management of Ships’ Ballast Water and Sediments,
2004 (“the Convention”), in two respects. First, they implement an amendment to the Convention
relating to the use of electronic record books. This amendment was adopted by International
Maritime Organization (IMO) Resolution MEPC.383(81) on 22nd March 2024 and came into force
on 1st October 2025. Secondly, they clarify the application provision in the 2022 Regulations.
Regulation 2(2) amends regulation 2 (interpretation) of the 2022 Regulations to insert a new
definition of electronic record book and omits the definition of “nominated body” which became
redundant as a consequence of amendments made to the 2022 Regulations by the Merchant Shipping
(Marine Equipment) Regulations 2025 (S.I. 2025/1280).
Regulation 2(3) amends regulation 4 (application) of the 2022 Regulations by substituting
regulation 4(2) and (4) (exceptions to the general application in regulation 4(1) of the 2022
Regulations). Regulation 4(2)(b) and (c) gives effect to the exceptions to the application of the
Convention in Article 3.2(b) and (d) of the Convention. This amendment clarifies that the exclusions
in those Convention provisions apply not only to ships operating in United Kingdom territorial or
controlled waters but may also apply to ships operating between those waters and the territorial or
controlled waters of the Crown Dependencies (while such ships are in United Kingdom waters or
controlled waters), in cases where the Secretary of State determines that the discharge of ballast
water from the ship would not impair or damage the environment etc. within the areas specified in
paragraph (2)(b) or (c) or those of adjacent or other States.
Regulation 2(4) and (5) respectively amend regulation 10 (ballast water record book) of, and insert
new regulation 10A (approval of electronic record book) into, the 2022 Regulations to give effect to
the amendment to the Convention made by IMO Resolution MEPC.383(81). Regulation 10 of the
2022 Regulations is amended to introduce a requirement that a ballast water record book, which is
required to be carried on board a ship, must be approved if it is in the form of an electronic record
book. Regulation 2(5) inserts new regulation 10A to implement the requirement for the approval of
such an electronic record book (by the Certifying Authority in respect of a United Kingdom ship, and
in respect of any other ship its flag State) to ensure it meets the standards outlined in the Guidelines
set out in IMO Resolution MEPC.372(80).
Regulation 2(6) makes consequential amendments to the offences provision in regulation 44 of
the 2022 Regulations. Regulation 2(7) and (8) amends several provisions in the 2022 Regulations
to update references to Merchant Shipping Notice MSN 1908 (M+F) Amendment 3. The current
Merchant Shipping Notice has been amended to reflect the new provisions.
Regulation 3 makes a consequential amendment to the entry for the 2022 Regulations in Schedule 1
to the Merchant Shipping (Fees) Regulations 2018 (S.I. 2018/1104).
