Marine Tunnel Thruster

Marine Tunnel Thruster

According to the propeller type, our marine tunnel thrusters are fallen into two types - fixed pitch propeller tunnel thruster (FPP type) and controllable pitch propeller tunnel thruster (CPP type). The tunnel thruster is widely used in various kinds of ships and can be driven by diesel engine or electric-motor. It can be installed vertically or horizontally; and is designed based on the concept of reliability, durability, high efficiency and easy maintenance. All of our marine tunnel thrusters are approved by CCS, BV, DNV, ABS, NK, KR, GL, etc. If you are interested in our products, please be free to contact us, we will answer you as soon as possible.
