Modular island data centre boosts satellite backbone

Secure I.T. Environments has completed a modular, containerised data centre for a global telecommunications provider on a remote South Atlantic island.

The site will handle ground operations linked to satellite connectivity and subsea backbone services. The supplier said the facility will run continuously in a coastal environment.

The project took place on an island about 1,800km west of mainland Africa. Secure I.T. Environments said the location presented constraints on transport, labour and construction access.

Logistics challenge

Secure I.T. Environments described rugged volcanic terrain and the absence of an access road to the build location. The company also pointed to limited sea freight windows and a single weekly flight that depends on weather conditions.

The firm said it had to plan deliveries, personnel movements and construction phases around the island's transport schedule. It also cited unpredictable weather as a factor that could disrupt flights and shipping.

Secure I.T. Environments said it worked with local organisations during the build. The company said members of the island community supported logistics and accommodation, and that the project created local employment.

A spokesperson for the client described the selection process for the contractor and the delivery plan. "This was such a crucial project for us, we did a huge amount of work ensuring we picked an experienced data centre builder, that could cope with the challenges. SITE supported us throughout the design phase, adapted to meet our needs, and created a very detailed plan for delivery and installation, focused on minimising risks. We are very pleased with the outcome," said the spokesperson.

Modular build

Secure I.T. Environments said the programme ran from initial design discussions through to commissioning over 12 months. The company said it completed the work on time.

The firm designed and manufactured a multi-container modular facility. It included a main data room, a separate UPS and switch room, plus lobby space.

Secure I.T. Environments said it adapted the mechanical design for high salinity and ocean spray. It cited modified air conditioning condensers, protective coatings and materials.

The company stated the build uses high-density IT racks and cold-aisle containment. It also listed N+1 cooling and modular N+1 UPS. Secure I.T. Environments also cited custom switchgear, fire detection and suppression, CCTV, access control and intruder alarms. It said the facility includes fibre raceways and full electrical infrastructure.

Secure I.T. Environments said it carried out integrated systems testing in the UK ahead of shipment. The firm said the testing reduced risk during on-island assembly and commissioning.

Market context

Telecommunications operators continue to add ground infrastructure as satellite services expand and subsea capacity grows. Remote locations can serve network coverage goals, but they also increase the complexity of deployment and maintenance.

Secure I.T. Environments positioned the use of containerised modules as a route to prefabrication and factory testing. The company said this approach suited the island's limited infrastructure and constrained freight options.

Chris Wellfair, Projects Director, Secure I.T. Environments, linked the project to delivery conditions and client expectations.

"This was an extraordinary project in every sense-remote location, complex logistics, and high client expectations. Our modular approach and close collaboration with clients ensured a smooth delivery despite the odds. It's a project we're incredibly proud of," said Chris Wellfair, Projects Director, Secure I.T. Environments.

Secure I.T. Environments said the completed facility will operate in a corrosive coastal climate and will form part of the client's ground operations on the island.
