Programme overview
What is the Diploma in Subsea Data Centres and Ocean Cooling?
The Diploma in Subsea Data Centres and Ocean Cooling
Prepares you to analyse and design solutions that use the ocean to cool digital infrastructure. You will study data centre thermal management, seawater air conditioning (SWAC) for coastal facilities, the experimental concept of submerged data centres, powering them with marine renewables, subsea cable connectivity, maintenance and environmental impacts, taking a cautious view of a technology path that is still being explored.
Key advantages
- Two sectors in one: Digital infrastructure and marine engineering in a single programme.
- Energy efficiency: Cooling is one of the largest energy loads in a data centre.
- A cautious approach: Proven coastal solutions alongside experimental submerged concepts.
- An environmental lens: Thermal effects, marine fauna and life cycle.
- Case study: Pre-feasibility study of a sea-cooled data centre.
