Britain should prioritize autonomous technology investments in harbor operations over ocean crossings, focusing on defined transport tasks like container transfers between terminals. Singapore’s autonomous feeder vessel program serves as a model, emphasizing reliability, safety, and integration with existing workflows rather than immediate cost savings. British suppliers could contribute by addressing specific challenges such as degraded visibility, cybersecurity, or terminal integration, but must clarify responsibilities and boundaries in contracts. Regulatory approval in the UK depends on vessel size, operating area, and use, requiring early engagement with the Maritime and Coastguard Agency to establish a clear pathway.
