In common with all responsible equipment operators the Royal Navy continues to seek ways to reduce ownership costs. In the particular case of gas turbines, over the last few years, this has taken the form of investment to achieve improvements in fuel efficiency. This route now ceases to offer large scope for improvement. The Royal Navy has therefore carried out an Investment Appraisal into the likely cost benefits which would result from improved life and reliability. The result of this study was to demonstrate a net present value cost advantage from entering into a joint venture development programme with Rolls-Royce to uprate and improve the Marine Spey SMIA.
