Bow Thrusters & Stabilizers

2 lessons

Lateral maneuvering and roll reduction: tunnel thrusters, White Gill azimuth jets, controllable pitch blades, Denny-Brown retractable fin stabilizers, hydraulic tilting mechanisms, and passive flume stabilizing tanks.

This chapter collects 2 illustrated lessons on Bow Thrusters & Stabilizers as part of Auxiliary Machinery & Shipboard Systems, ordered as they are best studied. It opens with Bow Thrusters & Azimuth Jet Units — Tunnel Thrusters, CPP Blades and the White Gill Jet, Fin Stabilizers & Anti-Roll Tanks — Denny-Brown Folding Fins, Hydraulic Tilting and Flume Systems. Each lesson is written for MEO oral and written preparation: definitions first, then how the system behaves, then the checks and figures used in practice.
