Jet Controls

A Revolution in Waterjet Control Systems

Unlike other electronic waterjet control systems, blue ARROW is a complete waterjet and controls package. blue ARROW incorporatessingle or twin waterjet units, jet control interfaces, engine throttle and gearbox control interfaces, together with helm station control devices.

In addition, blue ARROW has many safety features including multiplelevels of redundancy and a fully independent smart backup, together with comprehensive diagnostics and alarms, making it the safest and most reliable control system of its type.

blue ARROW is suitable for commercial applications, workboats, military craft and pleasure yachts. Like all of HamiltonJet's quality propulsion products, blue ARROW is installed and supported by the company’s network of distributors and service agents in over 50 locations around the world.

HamiltonJet Modular Electronic Control Systems (MECS)

The HamiltonJet Modular Electronic Control System (MECS) is a software configurable control system for waterjet steering and reverse, engine throttle and gearbox control. It comprises a number of standard modules which may be connected together in varying combinations to build a vessel control system. A key feature of MECS is that each module is standard and the configuration of a complete system for a particular vessel, with the exception of engine and gearbox interface wiring, is achieved solely through menu driven software configuration carried out during vessel commissioning.

The system modules are interconnected using a set of pre-terminated (plug-in) cables supplied with each system. The only additional hard wiring that the ship builder is required to complete is the power supply and interlock to a Power and Interlock Module and the engine and gearbox interfacing connections to the engine control module.

Within MECS there are two separate control subsystems. Normal control allows fully proportional control of the steering, reverse and throttle as well as control of the gearbox. Backup is provided as an independent set of controls intended for use if normal controls are not available.

In addition to the electronic modules, a complete system includes a jet mounted and driven hydraulic power unit (JHPU) on each jet, inboard hydraulic steering and reverse actuators and feedback units, engine and gearbox interfaces (or actuators) and other interfacing and sensing options.
