PROJECT-CONFIGURED COMMERCIAL SYSTEMS
Custom Fixed-Pitch Tunnel Thrusters
For duties outside standard catalogue ranges, ERBA Marine can coordinate a project-configured fixed-pitch tunnel package around the vessel, required thrust, tunnel structure, propeller geometry, drive source, controls and documentation.
SCOPE REVIEW
Custom Fixed-Pitch Tunnel Thrusters
Begin with the vessel operating profile, manoeuvring duty, available space, tunnel geometry, drive power, class or client requirements and the installation boundary.
What ERBA can coordinate
For duties outside standard catalogue ranges, ERBA Marine can coordinate a project-configured fixed-pitch tunnel package around the vessel, required thrust, tunnel structure, propeller geometry, drive source, controls and documentation.
- Project-defined thrust and manoeuvring duty
- Tunnel diameter, length, position, immersion and structure
- Fixed-pitch propeller and drive-source coordination
Interfaces to confirm
Final compatibility and performance depend on the complete vessel and system arrangement.
- Electric, hydraulic or mechanically integrated drive review
- Controls, alarms, interlocks and bridge interfaces
- Drawings, calculations, class/client documents and commissioning scope
SELECTION INPUTS
Send project and existing-equipment data
Begin with the vessel operating profile, manoeuvring duty, available space, tunnel geometry, drive power, class or client requirements and the installation boundary.
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
PROJECT PROCESS
From vessel data to written quotation
The model code is a reference starting point. The final supply is fixed only after the interfaces, duty and written commercial scope are reviewed.
1. Send vessel data
Share the general arrangement, dimensions, displacement, hull details, windage, available power and intended duty.
- Newbuild or retrofit
- Bow, stern or both
- Available drawings and photographs
2. Review arrangement
ERBA checks tunnel or retractable geometry, immersion, structure, power source, controls and service access.
- Space and interfaces
- Duty and environment
- Missing-data list
3. Select supply route
A supported manufacturer model or project-configured package is shortlisted for technical and commercial review.
- Make and model
- Accessories and documents
- Installation boundary
4. Confirm quotation
The written quotation confirms the exact configuration, warranty path, price, delivery and included services.
- No assumed inclusions
- Compatibility checkpoints
- Final written scope
FREQUENTLY ASKED QUESTIONS
Custom Fixed-Pitch Tunnel Thrusters 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.
Begin with the vessel operating profile, manoeuvring duty, available space, tunnel geometry, drive power, class or client requirements and the installation boundary. ERBA Marine will identify any missing information before defining the technical and commercial scope.
