Detailed description

Designed for vessels from 22 to 30 meters (72 to 100 feet), the Sleipner eVision E250 bow thruster delivers 250 kg of thrust at 24V for precise harbor maneuvers at the bow or stern. The system uses a 6-phase permanent magnet synchronous motor (PMSM) with integrated inverter, enabling variable speed control.

Advanced technology and performance

The eVision E250 bow thruster features Q-Prop™ five-blade contra-rotating propellers, reducing noise by 20 to 40% in normal use and up to 75% in controlled tests while maintaining thrust efficiency. Its PRO variable speed control system ensures smooth and quiet maneuvers, adjusting power as needed. The Hold-Function allows the vessel to hold alongside a dock with a single press, particularly useful with a twin thruster setup.

System integration and reliability

With a power output of 11.1 kW (14.9 hp) and a current draw of 580A, the Sleipner E250/300TC-24V is equipped with the S-Link™ CAN-based digital control system for reliable communication with other Sleipner equipment. Overheat protection is managed by a smart inverter and active cooling system, reducing power rather than cutting the thruster. Galvanic isolation of underwater components prevents corrosion, and the sealed gearbox lubrication ensures lasting watertightness. Certified CE/UKCA and compliant with ISO 8846 (Ignition Protected), it ensures safe operation. Its weight is 43 kg and tunnel diameter is 300 mm.

Expert opinion

« Technical analysis of the Sleipner eVision E250 thruster: performance and integration »

The Sleipner eVision E250 24V thruster is an advanced maneuvering solution for large vessels, typically between 22 and 30 meters. Its design with a PMSM motor and integrated inverter sets it apart from traditional DC thrusters by offering variable speed control, resulting in finer maneuverability and significant noise reduction thanks to the Q-Prop™ propellers. This technology not only allows precise adjustment of the required thrust but also prevents jerks and abrupt starts/stops, extending the system's lifespan.

Integration via the S-Link™ bus simplifies connectivity with other Sleipner equipment, providing a consistent and scalable system architecture. While the compact design and 43 kg weight are advantages, it is crucial to validate the 300 mm tunnel sizing and installation on the vessel. The ability to install at any angle within the tunnel is a practical benefit. The advanced thermal management, which degrades power rather than cutting the system in case of overheating, is a key feature for reliability during prolonged use, especially during complex maneuvers or in crowded harbors.

This thruster is particularly relevant for demanding owners seeking silent and reliable maneuvering assistance capable of operating for extended periods. It is essential to consult a professional for sizing and integration to optimize performance and ensure compatibility with the existing electrical installation and control accessories.

Frequently Asked Questions

Need help? Contact us

What is the thrust power of the Sleipner eVision E250 thruster?

The Sleipner eVision E250 thruster delivers 250 kg of thrust.

What is the required supply voltage for this bow thruster?

This thruster operates on a supply voltage of 24 V.

What is the required tunnel diameter for installing the eVision E250 bow thruster?

The tunnel diameter required for installing this thruster is 300 mm.

Why is this thruster only offered on a quote basis?

This thruster is offered only on a quote basis as it is a primary equipment requiring in-depth technical validation. This includes precise sizing for your boat, confirmation of voltage, study of optimal installation, and determination of necessary accessories to ensure safe installation and optimal performance.

What is Q-PROP technology and what are its advantages?

Sleipner's Q-PROP technology uses a five-blade, skewed propeller. Its main advantage is significantly reducing noise by 20 to 40% in real-world installations and up to 75% in controlled tests, while maintaining or improving the thruster's thrust performance.

What are the main technical characteristics of the Sleipner eVision E250 thruster?

The Sleipner eVision E250 bow thruster integrates several advanced technologies to optimize safety, control, and performance:

Q-PROP: A five-blade skewed propeller that reduces noise by 20 to 40% while maintaining or improving thrust.Intelligent Power Control (IPC): Minimizes mechanical wear by ensuring minimal delay between direction changes and monitors solenoid performance, cutting power to the thruster if a solenoid locks up.Overheat protection: Automatically detects high internal temperatures and shuts down the system before damage occurs.Galvanic isolation: All underwater components are electrically isolated from the onboard system to eliminate stray currents and prevent galvanic corrosion.Gravity-fed lubrication: A separate oil reservoir above the waterline feeds the gearcase by gravity, creating positive pressure for effective sealing and simplifying oil changes.Sealed drive system lubrication: Factory-filled, lifetime lubrication sealed with ceramic and carbon seals.Secure start: Control panels require dual-button activation to prevent accidental starts.

Can I use a remote control to operate the Sleipner eVision E250 bow thruster?

Yes, it is possible to add a remote control to operate the system remotely. This allows you to control the thruster without being at the helm, making manoeuvres easier, particularly during harbour manoeuvres with a reduced crew.
