How to use this 3D view
- Start the guided lesson — the side panel opens on step one. Each step sets up the model and names the components in view; move on with Next or step back with Back.
- Inspect the parts in view — the buttons under each lesson step list the components that step is about; choose one to highlight it in the model and read what it does in the panel below.
- Orbit and zoom — drag the model to rotate around it, scroll or pinch to zoom into details, and use Reset view on the model to return to the starting angle.
- Switch to Explore freely — when the lesson ends, switch the panel to explore mode for the complete parts list and the model steps for the roll reduction.
- Use View options — labels, exploded view, pan and full screen are always visible in the toolbar above the model.
- Read the topic — open Methods of Reducing Rolling: Fin, Bilge & Tank Stabilisers for theory, sketches and oral-prep questions.
What's inside this 3D model
- Fin stabilisers
- Bilge keels
- Passive flume tanks
- Controlled passive tanks
- Active controlled tanks
- Crossover duct
About: Roll Reduction in 3D
Run the active fins, the passive bilge keels and the three free-surface tank systems — passive, controlled passive and active controlled.
This free interactive 3D view of the roll reduction is built for marine engineers, cadets and seafarers preparing for orals — open it on any device, work through the guided lesson, explore all 6 labelled parts, and then continue with the full Methods of Reducing Rolling: Fin, Bilge & Tank Stabilisers topic.
FAQs
What does the guided lesson in this roll reduction 3D view cover?
The lesson walks you through the roll reduction in short steps — Fin stabilisers, Bilge keels, Passive flume tanks and more. Each step sets up the model, names the components in view and explains what they do, so you learn the arrangement before you explore it freely.
Can I explore the roll reduction instead of following the lesson?
Yes. Switch the side panel to “Explore freely” for the complete parts list and the model steps for this roll reduction. Labels, exploded view, pan and full screen are always visible in the “View options” toolbar above the model, and Reset view stays on the model itself.
Do I need to install anything to open the Roll Reduction 3D model?
No. The Roll Reduction 3D view runs entirely in your browser with WebGL — open the page on a phone, tablet or desktop, drag to orbit and pinch or scroll to zoom.
Where can I learn the theory behind the roll reduction?
Open the linked topic “Methods of Reducing Rolling: Fin, Bilge & Tank Stabilisers” below the viewer for the full explanation, sketches, oral-prep questions and related 3D simulations.
