Which Master's courses in the UK would best suit my B.Tech in Marine Engineering and 5 years of work experience in the maritime sector?

With 5 years already in the maritime sector, you do not need a foundational marine engineering degree, you need one that recognises your experience and either deepens your technical specialism or pivots you toward a growth area like offshore renewable energy.

Where your 5 years of experience carries the most weight

• UCL, Marine Engineering MSc: covers propulsion systems, electrical power systems and ship design, explicitly lists maritime-sector experience as desirable, and is accredited by IMarEST and RINA toward Chartered Engineer registration.
• University of Strathclyde, MSc Marine Engineering: designed for graduate engineers who want to specialise further in marine engineering, with links to the naval architecture and ocean engineering field.
• University of Southampton, MSc Maritime Engineering Science (Ocean Energy and Offshore Engineering pathway): a strong pivot option if you want to move from conventional shipping toward offshore energy, also IMechE, RINA and IMarEST accredited.

If you want to pivot rather than deepen

Strathclyde's MSc Sustainable Engineering: Offshore Renewable Energy explicitly lists Marine Engineering graduates as a good fit and can be the better choice if you want to move into offshore wind and clean energy rather than staying in conventional shipping or ship machinery.

University College London, University of Strathclyde and University of Southampton's own postgraduate course pages set out the entry requirements and accreditation details referenced above.

My Advice

Get your accreditation pathway confirmed before you apply, not after. IMarEST and RINA accreditation toward Chartered Engineer status depends on your underlying undergraduate degree meeting specific further-learning requirements, so ask each university's admissions office to check your B.Tech transcript rather than assuming accreditation automatically applies to you.
