From the bridge to the buoy.
Precision marine sensing, proven worldwide.

Marine systems use sensors to measure environmental conditions, vessel position, fluid levels, machinery condition and other operating parameters. Gill provides ultrasonic wind sensors, integrated weather stations, non-contact position sensors, liquid level sensors and oil debris monitoring technologies for marine and offshore applications.

A marine wind sensor should be selected according to the required wind-speed range, accuracy, output rate, environmental exposure, installation, power requirements and any relevant approvals. Salt, moisture, vibration and continuous operation can all affect the specification. Gill provides ultrasonic wind sensors in configurations designed for different marine and offshore requirements.

Ultrasonic wind sensors measure wind speed and direction without rotating cups, vanes or bearings. Removing these mechanical components eliminates a source of wear and can reduce maintenance requirements, which is particularly useful on vessels, offshore platforms, buoys and other installations where access may be difficult. Gill has more than 40 years of experience in ultrasonic wind measurement.

Marine weather monitoring may require wind speed and direction, temperature, humidity, atmospheric pressure, precipitation and other meteorological parameters depending on the application. Gill provides both individual ultrasonic wind sensors and integrated MaxiMet weather stations for marine and offshore monitoring.

Dynamic positioning systems combine information from several sources, which can include wind sensors, position and motion reference systems, heading sensors and feedback from propulsion and steering systems. The exact architecture depends on the vessel, DP class and operational requirements. Gill provides ultrasonic wind measurement alongside position, level and other industrial sensing technologies that can support the wider vessel measurement architecture.

Liquid level sensors can provide continuous measurement of fuel, ballast, bilge, service and other tank levels. Gill’s solid-state capacitive level sensors provide continuous level measurement without mechanical floats, with different configurations available for different fluids, tank materials and installation requirements.

Non-contact position sensors can provide feedback from equipment such as rudders, thrusters, hatches, ramps, davits and cranes without requiring mechanical contact at the measurement point. Gill’s Blade position sensors use a separate sensor and target, eliminating mechanical wear at the sensing interface and supporting both linear and rotary position measurement.

Oil debris monitoring detects metallic wear particles carried in lubricating oil, providing an indication of developing machinery wear between planned inspections or overhauls. Gill’s WearDetect can monitor fine and coarse ferrous debris, alongside water presence and oil temperature, for applications including main engines, gearboxes and thruster drives.

Yes. Gill marine sensors are designed to integrate with wider vessel monitoring, navigation and control systems using established communication interfaces. Depending on the product, interfaces include NMEA 0183, RS232, RS422, RS485 and Modbus. Gill also provides engineering support for applications where standard configurations do not fully meet the requirements of a particular marine system.

Marine sensing systems commonly use interfaces and protocols including NMEA 0183, RS232, RS422, RS485 and Modbus. The appropriate choice depends on the sensor, receiving system and vessel architecture. Gill provides these interfaces across its marine sensing range, with product-specific options depending on the application.

Certification depends on the individual product and application. Gill marine products include options with Lloyd’s Register Type Approval, and the WindObserver II also holds an ABS Product Design Assessment, while selected WindObserver configurations are available for hazardous areas with ATEX, IECEx and UKEX certification. The required approval should be confirmed against the vessel, installation and applicable classification requirements.

Calibration requirements depend on the application, measurement specification and applicable quality or regulatory requirements. Where traceability is required, calibration should be carried out by an appropriately accredited laboratory at an interval appropriate to the equipment and its use. Labcal is an independent UKAS-accredited calibration laboratory that supports equipment from Gill and other manufacturers, allowing customers to consolidate calibration across their wider measurement ecosystem.

An integrated weather station can combine multiple meteorological measurements within one instrument, reducing the number of separate sensors, mounting arrangements, cables and interfaces required. Gill’s MaxiMet Marine configurations provide combinations of wind and weather measurement, with selected models offering GPS and compass functionality for vessel applications.

Consider the measurement itself alongside the environment in which the sensor will operate. Wind range and accuracy, temperature, salt and moisture exposure, vibration, ingress protection, power, communications, approvals, installation and maintenance access can all affect the specification. Gill can support application-specific sensor selection across environmental and industrial measurement requirements.

Reducing mechanical components can remove potential sources of wear and maintenance. Gill’s ultrasonic wind sensors contain no rotating wind-sensing components, while its Blade position sensors and solid-state liquid level sensors avoid mechanical contact or moving components at the measurement point. The appropriate approach depends on the application and the environment in which the sensor will operate.
