Detailed in an updated technical catalogue, the range brings together air and hydraulic starters, flywheel turning mechanisms, air shut-off valves and flame-proof alternators into an integrated system tailored to the operational demands of vessel engine rooms, offshore support vessels and marine power installations.

For marine propulsion systems, dependable engine starting is critical to both safety and operational readiness. GALI’s air and hydraulic starters are engineered to deliver high torque and rapid start performance, enabling propulsion engines to reach ignition speed quickly, even under demanding onboard conditions. Operating directly at pressures of 30 to 40 bar, the systems remove the need for pressure-reducing valves while maintaining consistent performance in environments characterised by vibration, humidity and temperature variation.

The starter range supports engines up to and exceeding 12,000 kW, covering applications from auxiliary engines to large main propulsion units. Robust construction and low maintenance requirements are intended to support extended service intervals and minimise disruption during vessel operations.

To support safe pre-start procedures, GALI flywheel turning mechanisms allow controlled slow rotation of the crankshaft prior to engine ignition. This enables inspection and alignment checks within the engine room, while helping engineers identify potential issues such as hydraulic lock resulting from fluid ingress in cylinders. By facilitating these checks before start-up, the systems are designed to reduce the risk of damage to critical engine components and avoid costly downtime at sea.

In addition, the range includes air shut-off valves (ASOV), developed to address the risk of engine runaway in hazardous marine environments. In situations where flammable gases may be present, such as offshore support or tanker operations, the valves provide rapid isolation of the engine air intake, bringing the engine to a controlled stop when conventional shutdown methods are ineffective. The units operate across a temperature range of -20°C to 230°C and are suitable for installation within marine engine room conditions. Also new ATEX compliant flameproof alternators. They are designed to operate via drive belts and are ideal for industrial vehicles because of their reduced dimensions and installation versatility. Their maximum continuous power is 595W (14V) and 420W (28V) and can attain 840W (14V) and 630W (28V) within ten minutes and guarantee fast initial battery charging.

jbj Techniques states that the combined system reflects a growing emphasis on integrated engineering within marine propulsion, where starting, inspection and emergency shutdown functions are designed to operate cohesively.

In marine operations, where reliability, safety and compliance are paramount, such an approach supports not only engine performance but also the protection of crew, vessel and cargo throughout the full operating cycle.

The GALI product range is available in the UK through jbj Techniques, with full technical specifications provided in the latest catalogue.
