ACCU-
STEER
SLIDE 8
Primary Components, Non Follow Up Steering • Helm Pump • Header Tank • Jog Lever (Steering Control) • Stand-alone Autopilot
pumpset - Reversing Motor (HRP) or Continuous Running (HPU)
• Non-Drain Back Valve • Safety Bypass Valve • Cylinder • Tiller Arm • Rudder Angle Indication
(RAI) • Rudder Feedback Unit (RFU)
SLIDE 9
Characteristics of Vessels with Non Follow Up Steering
• Workboats, supply vessels – when the effort required on the wheel is too much
• Typically up to 120’ (35m) • Jog lever may become the primary
control for steering - helm pump is secondary
• Introduces valves to convert electrical signal from jog lever to move cylinders
• Adds components and aids in control of vessel

HEADER TANK
SLIDE 11
Primary Components, Power Assisted Steering
• Helm Pump
• Header Tank
• Accu-Steer Power Assist Unit
• Safety Bypass Valve
• Cylinder
• Tiller Arm
SLIDE 12
Characteristics of Vessels with Power Assisted Steering
• Ideally where the helm pump is a small displacement (to match PA Unit output).
• Small recreational or Small Fast Workboats/Pilots.
• Auto-pilot/jog can be incorporated
• Ease of configuration & maintenance
• To reduce the effort required to steer the vessel
• Reverts to manual if power not available
SLIDE 13
Special Note on Power Assisted Steering
Special Note:
• ‘Power Hydraulic’, ‘Power Assistance’, ‘Power Steering’ are descriptions that often gets applied to ‘Vessel Specification’ documents.
• You will have to be very sure about what is required, it could be this, NFU, FFU, or Orbitrol Steering (forklift/tractor type)
SLIDE 14
Hydraulic Full Follow Up
• System Shown With Non-Drain Back Valve, could be Header Tank and sealed main Reservoir
SLIDE 15
ACCU-
STEER
Primary Components, Hydraulic Full Follow Up
• Helm Pump • Jog Lever (Steering
Control) • Accu-Steer Unit • Non-Drain Back Valve • Rudder Feedback
Indicator • Power Assisted
Cylinder • Tiller Arm • Hydraulic Power Unit
SLIDE 16
Characteristics of Vessels with Hydraulic Full Follow Up
• For faster rudder speeds
• Pilot boats, harbour tugs, mid-sized yachts
• 80’ to 120’ (25m to 35m)
• Preference of wheel over jog lever
• Auto-change over to manual, helps with classification
SLIDE 17
Electronic Full Follow Up
SLIDE 18
ACCU-
STEER
Primary Components, Electronic Full Follow Up
• Helm Pump
• Header Tank
• Steering Controls
• Amplifier and Transfer Box
• Solenoid & Base Plate
• Non-Drain Back Valve
• Safety Bypass Valve
• Cylinder
• Tiller Arm
• Rudder Feedback Indicators
• Hydraulic Power Unit
SLIDE 19
Where are Electronic Full Follow Up systems used?
• On vessels where it is not practical to have manual steering or hydraulic FFU
• Mechanical tie bar not possible (Catamaran)
• Military, commercial, recreational
SLIDE 20
Types of Vessels & Typical Systems
• Manual Hydraulic and NFU / Autopilot
• Power Assisted & Hydraulic Full Follow Up
• Electronic Full Follow UP
SLIDE 21
All about the Rudder & Speed!!
• It all starts with steering torque…
• To size and quote a steering system, the torque required to turn the rudder is the most important metric
• From the torque, the size of the cylinder(s) and hydraulics can be selected
• The associated system components can then be added
Many catalogue sellers think its about the boat size!
SLIDE 22
General Information Needed
• Customer Name, Vessel; Name, Type, Length and Duty
• Rudder Dimensions and / or customer supplied steering torque
• Special Considerations; Nozzles, fish tail, flap rudder
• Hull: Full Displacement, Semi-Displacement, Planning, Catamaran, Other
• Hull: Steel, Aluminum, GRP, Wood
• Class Approval, New Construction / Retrofit?
• Speed (Knots): Cruising, Maximum, Estimated
• Propeller: Diameter (inches/mm), Pitch, Reduction. Gear Ratio
• Number of engines
• HP / RPM
• Idle RPM, Running RPM, Maximum RPM
• Gross Tonnage
