Design review of on-board air-conditioning systems for the Royal Navy

HMS Chiddingfold


As part of our commitment to the Royal Navy for continued through-life support of their installed equipment, Lightfoot was tasked with carrying out a detailed review of the air-conditioning and associated systems as the equipment OEM. This included upgrade options that embraced new technologies and a full obsolescence review.

The Royal Navy’s Installed equipment was over 25 years old, which lends itself to obsolescence issues and costly bespoke solutions for spares. The vessels were also operating in extreme ambient temperatures and humidity levels compared to the design parameters of the equipment when they were installed in the vessels, and so an Air-conditioning review was required.

What was delivered?

Lightfoot reviewed all historical operating data and failure rates. Using Root Cause Analysis Lightfoot was able identify suitable changes in the design that would mitigate future equipment failures int he Air Conditioning. Additionally, as part of the design review, Lightfoot, identified those design changes that would increase the equipment operating parameters to cope with the much wider ambient and humidity operating conditions.

What were the benefits?

Lightfoot reviewed equipment and component availability and used this information to produce an obsolescence report. Where shortfalls were identified, suitable (fit, form and function) replacements were found and detailed. This included full manufacturing drawings and specifications where no alternative components were available. This availability of current and future parts requirements ensured the continued equipment operations.
