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.
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.
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.
Lightfoot successfully bid for the contract to design and build a multi-room refrigeration plant for the Brazilian Navy flag ship aircraft carrier SAO PAOLO.
Lightfoot were contracted to supply a multi-room refrigeration system that included significant redundancy.
