Rolls-Royce TDI-11 Pitch & Direction Indicator Module

Rolls-Royce TDI-11 Pitch & Direction Indicator Module

Introduction

The Rolls-Royce Marine TDI-11 (commonly branded under the Rolls-Royce Oy Ab Aquamaster or Kamewa portfolio) is a precision, marine-grade electronic feedback and monitoring module. Primarily engineered as a Direction / Pitch Indicator, the TDI-11 plays a critical role in closed-loop navigation systems, providing real-time telemetry of thruster angles and propeller pitch settings. 

By translating raw positioning data into precise feedback loops, it ensures seamless communication between the bridge command control columns and the auxiliary machinery on commercial cargo fleets, specialized tugs, and offshore support vessels.

Related Models

The TDI control portfolio uses specialized monitoring and processing cards to balance varied signaling layouts across the bridge and engine room:

Rolls-Royce CMS / CMS-X: Centralized Azimuth Thruster Control Management Systems that act as the master host for the TDI-11 tracking loop.

Rolls-Royce MPC-210: Marine winch and auxiliary micro-processing speed module frequently configured in adjacent automation racks.

Rolls-Royce SLIO 01: Smart Loop Input/Output distributed fieldbus node used to interface sensor lines before signal transmission.

Application Cases

The TDI-11 indicator module is a staple spare part deployed in demanding propulsion topographies globally:

Aquamaster Azimuth Thruster Feedback: Delivers continuous, high-accuracy angular indexing for 360-degree steerable azimuth thrusters.

Controllable Pitch Propeller (CPP) Systems: Monitors the mechanical blade angle (pitch) of propulsion shafts to prevent torque mismatches and ensure clean hydrodynamic transitions.

Alang Vessel Retrofits & Replacements: Widely sought after as an exact-match drop-in replacement spare part during life-cycle maintenance overhauls for commercial vessels.

Product Advantages and Features

Ultra-Low Magnetic Signature: Features a certified Compass Safe Distance of just 0.2 meters, allowing tight installation profiles directly into main steering consoles without drifting magnetic navigation gear.

Pre-calibrated Microcode (Ver 1.08): Programmed with optimized CRC checksum integrity algorithms (CRC B723) to eliminate data jitter or sensor signal drift under high-load maneuvering.

Marine-Hardened PCB Architecture: Engineered to perform perfectly inside the harsh vibration zones of engine control modules and steering flat compartments.

Dual Order Compatibility: Seamlessly integrates with legacy system configurations running either the 23090.1 or 23090.2 production variants.

Installation and Maintenance

Installation

Console Placement: Flush-mount the TDI-11 module inside the bridge navigation rack or local steering control console panel.

Cable Isolation: Route signal feedback wiring through shielded marine cabling to maintain isolation from nearby high-voltage variable frequency drives (VFDs).

Grounding Verification: Securely connect the chassis ground terminal to the main ship hull earth system to prevent ground loops.

Maintenance

Signal Calibration Audits: Check feedback linearity semi-annually against physical thruster angles to ensure the indicator matches true physical pitch.

Terminal Torque Inspections: Check terminal block screws periodically to guarantee continuous physical contact under structural hull vibrations.

Environmental Enclosure Checks: Keep the hosting cabinet free from damp salt-air condensation; clean any visible terminal dust with electronic contact cleaner during dry-dock windows.
