Functional analysis for specification of an emergency power generator

The objective of this study was to define the Specification for modifications to be applied to an industrial emergency power unit so that it could fulfil specific requirements, notably in terms of the safety of the target application. This generator, classed as "important safety equipment", fulfils an emergency power supply function for a test nuclear reactor.
The study therefore involved defining the additional tests or studies which will make it possible to qualify the diesel generator unit with respect to these requirements. [...]

Functional analysis for specification of a ship propulsion system

When undertaking its ship-construction activities, our customer is subject to the requirements of reliability standards and must design its ships in such a way that they are always able to conserve 50% of the propulsive power and to retain the capacity for its control in the event of a single failure. CAPSIM was therefore given responsibility for defining a methodology capable of taking into account and guaranteeing that this constraint was met from the ship's design phase onwards. [...]

Feasibility study of replacement converter units

As part of a program for maintaining the operational condition of ships, the customer wished to study the feasibility of replacing the power converter sets which used rotary equipment with a solution based on static converters.
The power converter sets, consisting of a mechanically linked "direct current machine + synchronous machine", are reversible converter units which allow conversion of the AC 440/60 Hz power network to the 198 V DC battery network. This equipment, of old design, was ageing and becoming obsolete. Breakdown detection had become increasingly complex and the adjustment of the control loops as well as the requalification tests were increasingly tiresome.

The project therefore involved producing a functional analysis of the existing system in order to redefine the functions associated with the power generation system independently of the technology used. The functional analysis was to be used as the basis of a search for new technical solutions to respond to the requirement and to consult with suppliers. This consultation phase was followed a by technical assistance phase to analyze the feasibility of the proposed solutions. [...]
