A vessel built for performance
Built with advanced maritime technology, the 140ft vessel, capable of reaching speeds up to 28 knots, relies on cutting-edge waterjet propulsion systems. Designed and manufactured by a leading company, the quadruple HM571 waterjet systems provide unmatched maneuvering capabilities. This advanced propulsion method is crucial for crew and equipment transfers, where stability and precision are paramount. However, meeting these demands meant overcoming unique challenges in sensor performance.
Overcoming vibration-induced sensor failures
Initially, the vessel was equipped with potentiometers to monitor the hydraulic systems controlling the reverse duct and steering cylinders. These components are critical for steering and precise positioning, especially during complex maneuvers like hovering in place. However, the harsh marine environment and constant vibration proved to be a formidable adversary. The potentiometers failed within just two weeks, disrupting operations and highlighting the need for a robust alternative.
The Solution: non-contact P500 sensors
Faced with these challenges, the P500 Rotary inductive position transducer emerged as the perfect solution. Unlike traditional potentiometers, the P500 is a non-contact position sensor, making it highly resistant to wear and vibration. This design ensures reliability and durability in demanding environments, such as marine propulsion systems.
Each hydraulic system in the vessel now incorporates two P500 sensors to precisely monitor the position of the reverse duct and steering cylinders. This configuration enables:
- Precision: the ability to make micro-adjustments to the reverse duct and steering deflector allows the vessel to perform intricate maneuvers, including hovering in a fixed position.
- Durability: the robust design of the P500 ensures long-term performance, even under constant vibration and exposure to harsh environmental conditions.
- Safety and efficiency: reliable sensors are critical for precise control, reducing the risk of equipment failure and enhancing operational safety.
