Postgraduate Diploma in Tank Safety, Vaporisation and Bunkering
Online 800-hour Postgraduate Diploma in Tank Safety, Vaporisation and Bunkering. 8 modules with the IGF Code (ships using gases or low-flashpoint fuels), ISO 20519 (specification for bunkering of LNG-fuelled vessels) and DNV Phast. Assigned tutor and open enrolment.
Postgraduate Diploma in Tank Safety, Vaporisation and Bunkering — studying from New Zealand
Maritime engineering is significant for New Zealand, given its extensive coastline, large exclusive economic zone and a strong sailing and boatbuilding tradition. Auckland, often called the City of Sails, hosts boatbuilders, marine service providers and offshore engineering firms, while Maritime New Zealand regulates safety at sea. Opportunities include naval architecture, offshore energy and aquaculture, and the New Zealand Defence Force's naval fleet supports further demand.
Fees for New Zealand: NZ$1,770 (New Zealand dollar), with instalments and employer sponsorship available.

Questions from New Zealand
Which New Zealand bodies regulate marine and offshore engineering?
Maritime New Zealand regulates maritime safety and the operation of vessels, and Engineering New Zealand is the professional body for engineers. Marine surveying and certain roles require recognised certificates issued by official bodies. SEIUM's qualifications are private and not accredited by any national body, so they do not replace these requirements.
Do marine and offshore employers in New Zealand value private qualifications?
New Zealand has active marine, boatbuilding, port and offshore sectors, particularly in Auckland and the Bay of Plenty. Employers usually prioritise recognised certificates, licences and practical experience. A SEIUM qualification may support an application, but whether it is valued is for each employer to decide.
Can I study this part-time from New Zealand?
Yes. The programme is 100% online and taught in English, so no student visa is needed to study from New Zealand. You are assigned a technical tutor and must complete a final project. Fees are payable in instalments, and employer sponsorship is possible. Programme lengths range from 300 to 1,900 hours.

How you'll learn
Fully 100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: students progress at their own pace within the intake, which makes it easier to combine with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is DNV Phast, Aspen HYSYS, FLACS, PHA-Pro, in free, academic or evaluation versions. Tests are studied using real HAZID and HAZOP study procedures, bunkering safety zone calculations and LNG leak simulations. Assessment is continuous per module plus the final integrative project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Explain the properties of LNG as a marine fuel.
Compare types of containment tanks under the IGF Code.
Calculate boil-off generation and its management strategies.
Identify hazards of onboard gas systems.
Plan a safe bunkering operation with safety zones.
