Shipboard Automation
Overview
Shipboard automation refers to the integration of advanced technologies into a vessel's operations to enhance efficiency, safety, and reliability. These systems and solutions automate critical functions like propulsion, power distribution, navigation, and machinery control.
Benefits
- Enhanced Safety
- Operational Efficiency
- Predictive Maintenance
- Regulatory Compliance
Shipboard Automation is a critical component of modern shipbuilding, and NAG Marine is revolutionizing maritime operations by integrating advanced technologies to improve safety, efficiency, and sustainability.

Our Solutions
Tank Level Indicators
Tank level indicators are devices used to measure and monitor the amount of fluids within a tank, ensuring safe and efficient operation across various platforms. They help prevent overflows, manage inventory, and maintain optimal fluid levels in applications ranging from fuel systems to water storage.
Tank Level Indicators function by detecting the position of fluid within a tank by using radar technology and translating those readings into measurements.
Indicator Types
For more than 25 years, NAG Marine has been supplying Tank Level Indicator technologies to the Naval and Commercial Marine markets with over 30,000 units installed.
Oil Content Monitors
Oil Content Monitors (OCMs) are essential technologies for maritime and industrial vessels used to measure the concentration of oil in water discharges. These monitors ensure compliance with environmental regulations, such as the International Maritime Organization's MEPC.107(49), which mandates that oil content in discharged water must not exceed 15 parts per million (ppm).
OCMs function by analyzing water samples to detect oil presence. NAG Marine uses Fluorescence Detection Technology to accomplish this.
Fluorescence Detection Technology excites oil molecules to emit light, distinguishing oil from other substances like rust or algae. This method is less susceptible to interference from particulates. Once oil levels are detected, OCMs can trigger alarms or activate control systems to prevent non-compliant discharges. Many models also log data for regulatory reporting and maintenance tracking.
NAG Marine accomplishes this using the TD-107s instrument, in partnership with Benchmark. Using the Fluorescence Detection Technology, the TD-107s offers an accurate and reliable PPM measurement that complies with IMO's MEPC.107(49) and has been approved by the US Coast Guard and DNV.
Electric Valve Actuators
Electric Valve Actuators are devices that use electrical energy to control the opening and closing of valves in various systems. They convert electrical signals into mechanical motion, enabling precise regulation of fluid or gas flow.
Electric valve actuators consist of an electric motor, a gearbox, and a control unit. The electric motor receives an electrical input, converting it into rotational motion. This motion is transmitted through the gearbox, which adjusts the speed and torque to operate the valve. The control unit interprets signals from a controller, directing the actuator to move the valve to the desired position.
Actuator Types
- Quarter-Turn Actuators - Rotates a valve stem through 90 degrees to operate valves such as ball, butterfly, or plug valves. They convert an input signal (electric, pneumatic, or hydraulic) into mechanical motion, enabling precise control over valve positions.
- Compact & Space-Efficient
- High Torque Output
- Durability in Harsh Environments
- Remote & Automated Control
- Fail-Safe Operation
- Multi-Turn Actuators - Rotates a valve stem through multiple complete turns (typically more than 90 degrees) to operate the valve. They are ideal for valves that need to be adjusted incrementally to control flow rates accurately.
- Precise Flow Control
- High Torque Capacity
- Durability in Harsh Environments
- Remote & Automated Control
- Fail-Safe Operation
- Valve Control Systems - An integrated setup used to manage the operation of valves within industrial processes. It ensures that valves open, close, or modulate flow rates in response to real-time conditions, thereby maintaining desired process parameters such as pressure, temperature, or flow.
