Ride Control

Austal’s proven Ride Control system provides improved seakeeping capability through enhanced computer controlled motion reduction – ensuring a smoother, more stable, productive and comfortable ride for crew, passengers and cargo.

Austal Ride Control Interceptors

Austal Ride Control Interceptors are designed for high-speed vessels that require an efficient and cost-effective motion control solution. As ARC inteceptors are customised to suit the vessel’s transom profile, they are ideal for both monohull and multi-hull vessels.

Used alone, ARC interceptors provide both trim and list control. When combined with ARC’s Motion Control System, Interceptors also provide active pitch and roll motion control.

Features

  • Modular design for easy installation
  • Suitable for both new and retro-fit installations
  • Robust, impact-resistant blade and support skegs
  • Lightweight
  • Low Hydraulic power requirement
  • Automatic retract function

Benefits

  • Effective pitch and roll motion damping when managed by ARC’s Motion Control System
  • Can be used for trim and list control when active motion control is not required
  • Minimal impact on manoeuvring characteristics when retracted
  • Suitable for most hull configurations
  • Compatible with most propulsion methods
  • High lift-to-drag ratio
  • Minimal impact on the vessel’s structural design
  • No impact on the vessel’s hull shape
  • Customised to suit the vessel’s transom profile

Configuration

  • Stainless steel interceptor blade
  • Guide skegs and bearings
  • Stainless steel linkage rod and servo actuators
  • Hydraulic valve control system
  • ARC SmartPac (optional)

Efficiency

Austal Ride Control Interceptors provide a more efficient lifting force at high speeds (above approximately 25 knots) then traditional Transom flaps.

Low Power

ARC interceptors require 60% less power then traditional transom flaps therefore offering both cost and weight savings.

Active Control

When integrated with an ARC Motion Control System, ARC interceptors can effectively control both pitching and rolling motions.

Simplicity

The ARC interceptor blade can be customised to suit most transom profiles and has no impact on the vessels hull shape. The systems connection is readily adaptable to composite, aluminium, steel, and wood construction hulls. The ARC Interceptor System can be installed in conjunction with both water jet and propeller propulsion systems.

Operation

The operation of an ARC Interceptor is as simple as selecting either the trim/list or active operating mode. In the trim/list mode, trim and list are adjusted using arrows on the user interface. In the active mode, the response of the Motion Control System to sea conditions can be set using provided controller settings.

Range of Sizes

ARC Interceptor motion control solutions can be developed from 30 metres in size and above. The System can be optimised to your vessels operating requirements.

Austal Ride Control T-Foil for Hi-Speed Vessels

Austal Ride Control T-Foil is an efficient and cost effective trim and motion control device. The operation of a T-Foil is very similar to that of an aeroplane wing. Arc’s T-Foils are capable of generating significant lift in both the upward and downward directions. ARC’s T-foil is ideal for high-speed vessels.

When integrated with an ARC Motion Control System, T-Foils can actively control the vessel’s roll and pitch motions. When active motion control is not required, the ARC T-Foil assists in correcting vessel trim and list.

Features

  • Robust fabricated or Nickel Aluminium Bronze (NiBrAl) foil casting
  • Optional gland kit to allow servo actuator removal whilst afloat
  • Modular design for easy installation
  • Suitable for both new and retro-fit installations
  • Low hydraulic power requirement
  • Low maintenance design
  • Wet or dry fit installation options

Benefits

  • Suitable for most hull configurations
  • High force generation
  • High lift-to-drag ratio
  • Foils can be easily repaired
  • Effective pitch and roll damping when managed by ARC’s Motion Control System
  • Can be used for trim and list control when active motion control is not required

Configuration

  • Fabricated steel or cast bronze foil and aileron assembly
  • High strength servo actuator
  • Hydraulic valve control system
  • ARC SmartPac (optional)

Foil Strength

ARC’s T-Foils are offered in Bronze or fabricated construction. All foils are designed to withstand bottom-slamming pressures in excess of class society requirements.

Active Control

When integrated with an ARC Motion Control System, T-Foils can actively control the vessels roll and pitch motions.

Simplicity

The ARC T-Foil System has been designed to simplify installation tasks and to minimise the support structure complexity. The system readily adaptable to aluminium or steel construction hulls.

Flexibility

The ARC T-foils can be configured for wet or dry fit installation, allowing for greater flexibility of vessel maintenance.

Operation

The operation of an ARC T-oil is as simple as using either the trim/list or operating mode. In the trim/list mode, the trim and list are adjusted using the appropriate arrows on the user interface. In the active mode, the response of the Motion Control System to the current sea conditions can be set using the provided controller settings.

Range of Sizes

ARC has developed T-foil motion control solutions for vessels from 30 metres in size and above and can deliver a T-foil System optimised to your vessel’s operating requirements.
