REFERENCE DESCRIPTION

Hydraulic Retractable Thruster R300

R300 is a hydraulic retractable-thruster family requiring project-specific structure, hydraulic supply, cooling, controls and retraction space.

Reference-family role

R300 is a hydraulic retractable-thruster family requiring project-specific structure, hydraulic supply, cooling, controls and retraction space.

  • Retractable installation
  • Hydraulic drive
  • Project-specific structure, hydraulics, cooling and controls

Quotation boundary

ERBA may quote this reference family, another supported manufacturer or a project-configured solution after technical review.

  • No exclusive-supplier implication
  • No availability promise from catalogue presence
  • Exact make and model stated in writing
PUBLISHED REFERENCE FACTS

Use verified values as selection inputs

Only internally consistent current manufacturer-reference values are shown. They are not vessel-performance guarantees.

Hydraulic supply

Project-specific pressure, flow, return, cooling and control review required.

Nominal tunnel diameter

300 mm

Published vessel guidance

60–104 ft

Published configuration 1

R300/15 • 11 kW • 15 cc • 240 bar • 29 L/min

Published configuration 2

R300/21 • 17.6 kW • 21 cc • 240 bar • 44 L/min

Duty boundary

No family-level run-time entitlement is assumed; confirm the exact system and installation limits in writing.

CURRENT PRODUCT-CODE VARIANTS

R300 variant routes

Product codes distinguish voltage, material, motor or other configuration details. Confirm the exact row and latest manufacturer documents before quotation.

Code 317810

MAX POWER THRUSTER R300/15

  • Exact product-code verification required
  • Availability and included scope confirmed by quotation

Code 317811

MAX POWER THRUSTER R300/21

  • Exact product-code verification required
  • Availability and included scope confirmed by quotation
TECHNICAL BOUNDARY

Items that require written confirmation

Conflicts and compatibility limits are retained so reference data is not converted into an unsupported promise.

  • Retractable installation
  • Hydraulic drive
  • Project-specific structure, hydraulics, cooling and controls
  • No exact family thrust rating is normalized; selection depends on the hydraulic operating point.
  • Product-table point values and data-sheet operating ranges must be reconciled for the exact variant.
  • Catalogue reference does not establish ERBA stock, authorized-dealer status, warranty route, regional approval or guaranteed availability.
  • The written quotation confirms the final manufacturer, model, documents, warranty path, delivery and included services.
SELECTION INPUTS

Selection data for R300

Confirm the vessel, installation geometry, power source, controls, duty and documentation needs before applying any reference value.

Vessel & duty

Define hull, displacement, windage, operating conditions and manoeuvring duty.

  • Vessel type, newbuild / retrofit / replacement and operating area
  • Length overall, beam, draft, displacement and loading condition
  • Hull material, thickness and available structural drawings
  • Windage profile, superstructure and expected manoeuvring conditions

Installation

Confirm tunnel or retractable geometry, immersion, structure, drainage and access.

  • Bow, stern or combined requirement and desired operating duty
  • Existing or proposed tunnel diameter, position, immersion and clearances
  • Available internal space, access, drainage and maintenance route
  • DC voltage and battery capacity or AC supply, phase and frequency

Power & scope

Coordinate electrical or hydraulic supply, controls, documents and delivery boundary.

  • Hydraulic pressure, flow, return, cooling and filtration if available
  • Control stations, joystick, proportional control and remote requirements
  • Flag, class, client documentation and inspection requirements
  • Delivery location, schedule and installation / commissioning boundary
FREQUENTLY ASKED QUESTIONS

R300 Hydraulic Retractable Thruster Reference questions

These answers preserve the technical-review and written-quotation boundary for every reference route.

No. The detailed catalogue pages use current Max Power models as clear reference examples because ERBA Marine deals with this equipment, but ERBA can also review other supported manufacturers or a project-configured package. The quotation confirms the final make and model.

No. Published values are manufacturer-reference data and depend on the exact variant, voltage or hydraulic supply, installation geometry, immersion and operating conditions. ERBA Marine confirms the quoted configuration only after technical review.

Yes. Send the existing model and nameplate, tunnel or hull-opening dimensions, vessel drawings, power information, controls, photographs and the required new duty.

Continuous or extended duty must not be assumed. Duty limits depend on the exact electric or hydraulic system, cooling, batteries or power pack, controls, installation and current manufacturer instructions.

No. It is a current manufacturer-reference family page. Vessel data, installation geometry, duty, power, controls, documents and availability must be reviewed before the written quotation confirms the final make, model and product code.
