Diploma in Chemical Compatibility of Materials and Coolants
Online postgraduate diploma of 800 hours in chemical compatibility of materials and coolants. 8 modules covering coolant chemistry, high-temperature water corrosion, liquid metals, molten salts, gas cooling, polymers and chemical monitoring under EPRI guidelines and ASME BPVC Section III Division 5, with an assigned technical tutor.
Diploma in Chemical Compatibility of Materials and Coolants — studying from Singapore
Singapore maintains a comprehensive defence sector through the Ministry of Defence and the Defence Science and Technology Agency, which develops military technologies and manages procurement. Engineering work covers land systems, ammunition, command and control, and simulation. Industry partners include ST Engineering, which supplies defence and security systems globally. Engineers here work within strict security and export control frameworks, often combining systems integration with reliability and safety engineering.
Fees for Singapore: S$2,560 (Singapore dollar), with instalments and employer sponsorship available.

Questions from Singapore
How does defence engineering work in Singapore, and which bodies oversee it?
Singapore's defence engineering is largely centred on the Ministry of Defence (MINDEF) and DSTA, the defence procurement and development agency, along with the Singapore Armed Forces. Engineers may register with the Professional Engineers Board (PEB). SEIUM's qualifications are private, not state degrees, and not accredited by any national body, so recognition for defence roles depends on the employer or relevant authority.
Who employs defence and land systems engineers in Singapore?
Main employers include MINDEF, DSTA, the SAF, and defence industry companies including ST Engineering. Access to many roles requires security clearance and citizenship or residency rules, so check eligibility early. Employers focus on proven competence and clearance status. Your final project can illustrate technical capability, but it does not replace these requirements.
Is the course manageable alongside a job, and can employers fund it?
The programme is fully online and taught in English, with an assigned technical tutor. Plan for a heavy workload: 1,900 hours for a master's, 800 for a postgraduate diploma, or 300 for a specialist course. Fees are payable in instalments, and employer sponsorship is possible, which is common in defence-linked organisations, though approval is up to them.

How you'll learn
A 100% online programme on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within the intake, so it fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is OLI Studio, Thermo-Calc, FactSage and COMSOL Multiphysics, in free, academic or evaluation versions. Testing is studied through real procedures for autoclave corrosion testing, molten salt immersion testing and primary circuit chemistry monitoring. Assessment is continuous by module, plus the final project.
Standards covered: EPRI PWR Primary Water Chemistry Guidelines, EPRI BWR Water Chemistry Guidelines, ASME BPVC Section III Division 5, ASTM G31, ASTM G1, ASTM G111, IEEE 383-2015.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
