Diesel Engine Tunnel Thrusters – High-Power Maneuvering System
Product Overview
Our Diesel Engine Tunnel Thrusters deliver high-performance lateral thrust for dynamic positioning (DP) and precision maneuvering in demanding offshore and marine applications. Available in 20KW to 3000KW power ranges, this system is engineered for extreme load conditions with FPP (Fixed Pitch Propeller) or CPP (Controllable Pitch Propeller) configurations.
Key Applications
✔ Dynamic Positioning (DP) – Station-keeping in harsh offshore environments
✔ Slow-Speed Maneuvering – Enhanced control for docking & tight navigation
✔ Heavy-Duty Operations – Ideal for offshore supply vessels, drillships, and large commercial ships
