Postgraduate Diploma in H₂ at 350/700 bar and LH₂: Systems and Safety — studying from the United Kingdom
Naval and offshore engineering is a significant sector in the United Kingdom, with shipbuilding and naval programmes on the Clyde, in Portsmouth, Barrow-in-Furness and Rosyth, and offshore energy activity in Aberdeen and the North Sea. Companies such as BAE Systems Maritime, Babcock and offshore service providers employ engineers in design, construction and maintenance. Sports nautical engineering, including yacht design and marine leisure, is concentrated in the Solent and South Coast. The Maritime and Coastguard Agency regulates shipping safety, and the Royal Institution of Naval Architects supports professional standards.
Fees for the United Kingdom: £746 (Pound sterling), with instalments and employer sponsorship available.

Questions from the United Kingdom
Which UK bodies relate to naval and marine engineering, and does SEIUM training count towards them?
Key UK bodies include the Royal Institution of Naval Architects, the Institute of Marine Engineering, Science and Technology and the Institution of Mechanical Engineers. Maritime qualifications are often regulated through the Maritime and Coastguard Agency for certificates of competency. SEIUM's private qualifications are not accredited by these bodies, so any recognition would be decided by them separately.
Will UK offshore, naval or marine employers value a private online engineering qualification?
Employers in these sectors often prioritise certified competencies, sea-going experience and regulatory certificates. A private qualification may support your application where it shows relevant technical depth, but it does not replace statutory requirements. Acceptance is for each employer to decide, so consider how the qualification complements your existing certifications.
Can I study this online from the UK alongside offshore rotations, and is language support available?
Online study can be flexible, but rotation patterns make scheduling important, so plan around your time at sea or on site. Programmes are taught entirely in English, and each learner is assigned a technical tutor. No visa is required to study from within the UK. Fees can be paid in instalments, and employer sponsorship is possible.

How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetables: students progress at their own pace within the enrolment period, which makes it easy to combine with work.
Each module combines theory, guided reading of the original standard and applied exercises. The software used is HyRAM+, DNV Phast, Gexcon FLACS, Aspen HYSYS, MATLAB, in free, academic or evaluation versions. Case studies are based on real procedures for quantitative risk analysis of hydrogen installations, dispersion and deflagration modelling, and techno-economic assessments of supply chains. Assessment is continuous per module, plus the final integrative project.
