When the time came for a technical refresh of Restricted and Secret standard Maritime desktops, Centerprise were invited to bid due to a rich history of bespoke engineering. Centerprise were awarded 100% of the contract, replacing a long-standing incumbent.

 

Our challenge was to deliver up to 5,200 custom designed and built UADs for the DIIF Maritime Program as part of a technical refresh requirement for Restricted and Secret standard Maritime desktops, whilst working to strict technical constraints.

 

Centerprise designed and built the Renatus M61 that adhered to the very specific volume requirement of 6188cm3. Only specially selected components were selected for these units, including an MoD approved motherboard. The use of centrifugal fans ensured that cooling capability was maximised and a solid state drive was included to withstand greater temperature and humidity variances.

“To displace the incumbent supplier was a fantastic achievement for the Centerprise team. The Renatus M61 has been built based on our first class design and production standards.””

Rafi Razzak - Chairman, Centerprise International

The chassis was manufactured from corrosion free aluminium, with fully welded seams that provided strength and robustness. Very specific attention had to be paid to the dimensions of this unit, as there were very tight restrictions on the overall volume. The chassis was designed to fit within the constraints of the enclosure and could be mounted in a left or right orientation providing access to the cables from either side.

 

The motherboard that was used in this design, had previously been approved for use by the MoD. It also provided the benefit of being able to run 24/7, as well as having memory slots orientated in such a way that airflow would not be obstructed.

 

We also decided to fix the processor heat sink to the chassis itself via the motherboard. This ensured that it would not become displaced from the processor. The use of centrifugal fans as opposed to an axial variant in this design, also ensured that cooling capability was maximised. This type of fan has the added benefit of being able to increase the speed of the air stream using kinetic energy.

 

Centerprise also opted to use a solid state drive (SSD). This ensured that a higher performance could be achieved against a standard mechanical drive, as well as achieving greater reliability and much less thermal output. Finally, we ensured that an Intel lower power processor was used, again, providing much needed heat and power benefits.

Using an industry standard chassis was never an option for the Maritime desktop as it was to be housed in a constrained and potentially harsh environment. Only with a thirty year history of building bespoke PCs were Centerprise able to meet the customer’s requirements with our Renatus M61 unit, which was specifically designed and built by our experts for this project.

 

This is the case at The Royal Navy, part of

the UK MoD, sworn to protect the security,

independence and interests of our country

at home and abroad.

 

Through the DIIF Maritime Program, a technical refresh requirement for Restricted and Secret standard Maritime desktops was initiated.

 

The technical constraints surrounding this project meant that it was never an option to use an industry standard chassis design, as it would not be fit for purpose. This in turn meant that many other aspects had to be considered, such as EMC and LVD testing, as these units were to be housed in a constrained, and at times potentially harsh environment.

 

Centerprise had to pay very specific attention to the design of the chassis in particular.

Another aspect that had to be considered was airflow. By volume, the chassis design that Centerprise proposed in order to comply with the stringent requirements, was 49% smaller than a standard design small form factor chassis. This created considerable problems for the design team, to be able to house the necessary components in considerably less real estate, whilst having sufficient cooling and performance.

 

 

“By investing in our production facility we have been able to compete with some of the largest manufacturers in the world and provide flexible and agile solutions where others cannot.”

Martyn Jones - General Manager, Centerprise International

 

Having previously supplied custom built PCs to the MoD through the Atlas Consortium, Centerprise developed a relationship capable of truly understanding the customer requirement.

 

By doing this, Centerprise were able to provide a unit that met the challenges of physical space, longevity of supply, software image stability and addressing the environmental hurdles posed by Maritime use.

Through our extensive design review process, we were able to design a UAD with two variants that addressed the very specific criteria for the DIIF Maritime Programme.

Whilst the unit was bespoke in design, we very carefully chose industry standard components to ensure we mitigated any risk associated with long term supply.

 

The Renatus M61 represents a high performance machine that is small and robust.

 

The unit is certified to mechanical shock- testing to DefStans 59-411 meaning it remains a complete, functional unit after any shock xact requirement.

There is still a lengthy build and roll-out required for this project, as the installation of the Renatus M1 can only be completed when vessells are docked.

 

Centerprise are continuing to research and develop innovative practices to ensure the custom built Renatus range of PCs offer the best level of performance possible.
