In modern warships the electrical power and propulsion system is fundamental to the end capability of the vessel. The Type 26 Global Combat Ship will utilise an advanced CODLOG (Combined Diesel Electric or Gas Turbine) propulsion architecture. The integration of this advanced architecture poses a number of engineering challenges and risks. The general philosophy towards de-risking taken at BAE Systems Naval Ships is one of left shifting project risk, whereby risks are considered and mitigated at the earliest opportunity in the development lifecycle. The electrical power generation and distribution system for Type 26 is considered to pose one of the largest integration risks within the Power &Propulsion (P&P) System. There are electrical power and propulsion integration risks in areas such as the overall quality of power supply (QPS), ship performance during transition modes and diesel generator ramp rates. Another key risk is the physical, functional and control integration aspects of the P&P system, with each piece of equipment needing to be integrated with the wider P&P system and the overarching Power Management System. In this paper, the de-risking strategies that have been put in place to minimise risk in respect of the power and propulsion integration system for Type 26 are presented. Chiefly, these activities involve the development and utilisation of computer based mathematical models of the power and propulsion and electrical power systems, and the construction of shore based integration test facilities.
