IMO published the Explanatory Notes to the Interim Guidelines on Second Generation Intact Stability Criteria

The International Maritime Organization has published the Explanatory Notes to the Interim Guidelines on Second Generation Intact Stability Criteria.

The circular (MSC.1/Circ.1652) was published on 26 April 2023.

The Maritime Safety Committee, at its 102nd session (4 to 11 November 2020), approved the Interim guidelines on the second generation intact stability criteria (MSC.1/Circ.1627) (Interim Guidelines).

In approving the Interim Guidelines, the Committee recognized the necessity of developing associated explanatory notes to ensure uniform interpretation and application.

To this end, the Committee, at its 105th session (20 to 29 April 2022), approved the Explanatory notes to the Interim guidelines on second generation intact stability criteria (Explanatory Notes), set out in the annex, as prepared by the Sub-Committee on Ship Design and Construction, at its eighth session (17 to 21 January 2022).

The Explanatory Notes are intended to provide Administrations and the shipping industry with specific guidance to assist in the uniform interpretation and application of the Interim Guidelines.

Member Governments are invited to bring the annexed Explanatory Notes to the attention of all parties concerned, in particular shipbuilders, shipmasters, shipowners, ship operators and shipping companies, and recount their experience gained through their use to the Organization.
