The 2018 CIMAC UK NMA combined AGM and Members’ Day was held on 28 November at the IMechE in London. We kicked off proceedings with the AGM, which included a discussion of UK plans to host the CIMAC Congress in 2025 and a presentation to introduce the new CIMAC UK NMA website to the membership. Four excellent presentations were then delivered by Charlotte Røjgaard of Bureau Veritas, Mark Penfold of ABS, Matthew Keenan of Ricardo UK, and Adrian Pask of BP Marine, along this year’s Members’ Day theme of the “Impact of Emission Regulations on Large Engine Operation”. Feedback from the 26 members attending was very encouraging, with the event being ranked as the best in recent years. Members registered a particular interest in gas engines, field experience and the practical aspects of engineering (so the planning of future events will take this into consideration).
