The Royal Institution of Naval Architects (RINA) to host the Technical Conference: Managing CII and Associated Challenges at the IMO in London, United Kingdom in January 2024

10 August 2023 – On 16-17 January 2024, maritime industry professionals will gather for the Technical Conference on Managing CII and Associated Challenges at the International Maritime Organization’s Headquarters, London, United Kingdom, hosted by RINA.

As part of its commitment to addressing climate change, IMO has developed a Carbon Intensity Indicator (CII) for international shipping. The CII is intended to measure and drive improvements in the energy efficiency of ships. CII was adopted in 2021 as part of a package of amendments to MARPOL Annex VI, which were a response to the IMO’s Initial Strategy on Reduction of GHG Emissions from Ships. IMO’s Strategy sets out a vision to improve the carbon intensity per transport work of shipping by 40% in 2030 relative to 2008.

The CII has been designed as a key tool to assess and monitor the carbon intensity of both new and existing ships, with an emphasis on operational efficiency that was not addressed by other IMO short term GHG measures. CII requirements took effect from 1 January 2023, so in early 2024 the industry is expecting to receive the first feedback of CII measures. A review of the effectiveness of the implementation of short-term CII and EEXI requirements must be completed by 1 January 2026, and it was agreed at MEPC 80 in July 2023 that this process would commence at MEPC 81 in March 2024.

The Royal Institution of Naval Architects is proposing the Technical Conference as an opportunity for  maritime influencers to gather and discuss the challenges and opportunities arising from this measure.

“We are delighted to be hosting a technical conference on Managing CII and Associated Challenges, says RINA Technical Director, Dmitriy Ponkratov. “The challenge of decarbonisation is at the forefront of maritime industry concerns, and we believe that the CII requirements taking effect this year will result in many important discussions by early 2024. We are looking forward to providing a platform for those discussions and invite key stakeholders of the maritime industry to join us and share their views as well as discuss the latest developments.”

“This is a timely initiative, and it is good to see that high-profile stakeholders have announced already that they will take part,” comments Volker Bertram, Senior Project Manager at DNV.

Edwin Pang, Founder of maritime consultancy Arcsilea Ltd and Chair of the RINA IMO Committee, adds: “The conference is a great opportunity to learn about both successes and challenges in implementing the CII, and ideally timed to feed into the review of the short-term measure.”

The Technical Conference on CII and Associated Challenges is open to all interested parties, including members of RINA, other professional institutions, and the wider maritime industry. Registration for the event is open, and further details can be found on the RINA website:
