1. Rec 105 (Corr.1 Jan 2022)
Rec 105 provides guidance for a qualification scheme for welders intended to be engaged in welding of aluminium alloys specified in UR W25 for hull structures. This revision has been updated
to make minor editorial amendments.

2. Rec 165 (Rev.1 Jan 2022)
Rec 165 gives recommendations for assessing alternative (novel) design instance and alternative (novel) design method (technology). This revision has updated guidance for the assessment ofalternative (novel) design instances and conventional designs for which alternative (novel) design methods (technology) or alternative design and calculation methods were applied during thedesign process.

3. Rec 95 (Rev.1 Mar 2022)
Rec 95 sets forth a set of guidelines for determining compliance with the principles and aims of SOLAS regulation V/15 relating to bridge design, design and arrangement of navigational systems
and equipment and bridge procedures when applying the requirements of SOLAS regulations V/19, 22, 24, 25, 27 and 28 at the time of delivery of the newbuilding. After a 10th anniversary review,references to external documents were amended and a new line for BNWAS alerts were included in this revision.

4. Rec 166 (Corr.2 Apr 2022)
Rec 166 provides technical information to stakeholders for the development of cyber resilient ships, whose resilience can be maintained throughout their service life. This revision has been updated
to incorporate the new paragraph 1.1.6 to specify the relationship between Rec 166 and the new UR E26 Cyber Resilience of Ships.

5. Rec 170 (New May 2022)
Rec 170 provides recommendations on the term of “heavy load carrier” for the consideration of application to EEDI/EEXI and CII, associated with the definition in Regulation 2.2.15 of MARPOL
Annex VI.

6. Rec 171 (New Jun 2022)
Rec 171 has been developed with a view to addressing cyber safety issues within the context of MSC-FAL.1-Circ.3, Guidelines on Maritime Cyber Risk Management.

7. Rec 172 (New Jun 2022)
Rec 172 has been developed in response to Resolutions MEPC.333 (76), MEPC.334 (76), and MEPC.335 (76) relating to EEXI.

8. Rec 134 (Rev.1 Oct 2022)
Rec 134 provides classification societies with reference information to be used in developing Boat Transfer procedures or technical instructions for their surveyors, according to a common
reference standard of good practice. This revision has been updated to align provisions of the document with Members’ own internal procedures/rules, their experience/expertise, as well as
relevant requirements/guidelines of IMO, ISO/IEC standards, other international standards, and best practices within the industry.

9. Rec 60 (Corr.1 Nov 2022)
Rec 60 provides recommendations for tankers which are not subject to MARPOL Annex I Regulation 27 regarding intact stability during liquid transfer operation. The Corr.1 updates footnote 2 torefer to the 2008 IS Code rather than UI LL61 which is proposed for deletion.

10. Rec 173 (New Nov 2022)
Rec 173 contains a set of requirements for numerical calculations to be used for the purposes of deriving the Vref in the framework of the EEXI Guidelines.

11. Rec 34 (Rev.2 Dec 2022)
Rec 34 provides advice on sea states by specifying wave spectrum, spreading, heading distribution and vessel speed. Following indications that the representation of North Atlantic waves in Rec
34 (Rev.1 2001) may have become outdated, IACS began work in 2018 on a long-term review of wave data. In this revision of Rec 34, IACS has derived significant wave height from modern data
sources for North Atlantic accounting for more extreme weather experienced in recent years, including the possible effects of climate change.
