The RNLI required a control system that was fully configured prior to installation to limit both installation complexity and access by unauthorised personnel. The first of class vessel has been supplied with all calibration access left open.

Once trials have optimised vessel performance the settings will be fixed and access limited to speed adjustment only, enabling a fine match for each engine.

The new BridgeMaster also incorporates an event logger which logs significant inputs and responses which can be downloaded to a PC or viewed via the LCD display. For the RNLI, it enables a clear record of events to be reviewed when required. Another benefit is the enabling of remote propulsion system problem diagnosis, saving significant downtime and onsite engineer costs.

When developing BridgeMaster, RCS targeted capability, flexibility, simplicity of use and cost. Designing the hardware to accommodate almost all marine propulsion designs, they created a software system that is simple to use and easy to calibrate through the LCD display. This allows the user to optimise the system during sea trials without the need for experienced commissioning engineers. A two wire RS485 communication system minimises the hidden overheads often associated with control system installation.

At the concept stage RCS incorporated all the variations they had encountered over 40 years of developing controls.

As a result, BridgeMaster accommodates CPP, reversing gearbox, azimuthing, Voith, direct reversing engines and water jets. Unique features are incorporated within these systems, such as pitch feathering, which can be used for a range of vessel types from motorised sailboats to twin engined fast patrol craft.

Combinator control is available with two performance curves to optimise and synchronise speed for differing needs, ideal for tugs.

Although BridgeMaster can accommodate other manufacturers' control heads, the RNLI has chosen the RCS compact model, which can be mounted on a standard armrest. RCS now have a production model ready for market and are preparing for Lloyds Approval, with deliveries expected by the New Year.
