IN DEPTH NAVAL SHIP DESIGN
Simulation: Starts with vessel inputs but sensibly has not been used for general arrangement design but largely combat systems issues.
3. Daniel Boyce with Claire Earlie (main author) (BMT) – A global view of the implications of climate extremes on sustainable ship design and operability. With more energy in the oceans, the conclusion was there would be more stormy weather in combination with “stormy" politics.
Annabel Ransome- Williams, programme director for SSN
AUKUS, stressed that “the human is at the centre of design”
the interfaces and made any new components backward-compatible. This conceptually provided an inspirational and successful model to follow. Naval forces would be developed in the light of:
• • State level competition • Demographic changes.
• Affordability, noting Norman Augustine’s statement, “Change is linear, cost is exponential”
Technological proliferation
• Climate change and its likely impact on world stability
systems’ future force mix, where the funded force must cost less and the crew-able element of the force must be reduced. One proposed concept is a blend of crewed and uncrewed ships, where the advantages could be commanded by a command vessel. This will present challenges in terms of local and shore control versus autonomy. The Lego concept, with a catalogue of parts with built-in adaptability (the connections), offers the vision of simpler, cheaper warships. A lively discussion ensued, thanks to Captain Mo’s intriguing
Presentations overview There now follows: the name of each lead presenter of 12 of the conference papers; each paper’s broad topic; and a brief summary of each presentation. This is reproduced below to encourage readers to read the full 25 papers in the conference proceedings. This report concludes by summarising the remaining activities that ended the last session of a successful conference. 1. David Manley (MoD and UCL) – Support to Concept Analysis and Requirement Development Through Wargaming: An outline of using wargaming to assist in the early concept design tactical study, emphasised that there was a lot of human interaction, giving insights as a “bird’s eye view”. This approach has now been introduced into teaching early-stage ship design at UCL.
2. Jakub Orlowski (Damen Naval Systems) – Validating Operational Scenarios Through
THE NAVAL ARCHITECT
4. Dan Patten (BMT) – Balance of Survivability for Large Uncrewed Surface Vessels: Elucidating the requirements and possibilities: The layout of an example 65m, 15knot-vessel was found to give improved survivability, but recoverability could then be problematic with accessibility still needing to be provided.
5. Matt Toon with Rodrigo Fernandes Perez (main author) (Siemens Digital Industries Software) – Advancing Smart, Sustainable, and Autonomous Fleets with Digital Innovation Tools: The authors concluded that the design spiral representation of the ship design process should be dispensed with. Digital twin technology “must age through life [TL]” and next-generation machinery will be developed using a TL “digital thread”.
6. Alex Barber and Ian Groom (Safeguard Engineering) – A Functional Safety Assessment Approach to Support Level 4 Autonomy: Level 4 autonomy removes humans directly in the loop, so was seen to be unrealistic for naval deployment. The issue of low-probability, high- impact safety assessment remains problematic in safety practice due to its inherent lack of data.
7. Teresa Magoga (DSTL) – Advanced numerical simulation of hydro-elastic vessel structural response to assist sustainability assessments: A hydro-elastic structural assessment should be part of any maintenance plan as a ship ages, with the need to predict stresses in harsh seaways – noting that strength is the only ship characteristic that only the naval architect cares about – until the hull breaks!
8. Harriet Morley (BAES), Submarine Crewing – Getting the balance right - how Future Digital Tools can Support the Generation and Validation of Submarine Crewing: This paper engineering and raised the issue of governance over personal data. It was seen as an issue of naval culture. Submarine crews will only be reduced when designers show the crewing authority that this will really save money if the on submarine size and cost.
9. Nick Danese (SSI) – Model-Based Sustainment: Digital Solutions for Improving Asset Availability: From experience with RCN/USN/ RAN, 55% to 70% of warship lifetime costs are in service, so the author concluded that naval ship acquisition, in common with a digital future, must emphasise user-friendliness.
10. Micha Stam (TUDelft) – Modular naval vessels and the impact on the design and effectiveness: Modularity can be based on geometric
