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 double bottom.
- Use View options — labels, exploded view, pan and full screen are always visible in the toolbar above the model.
- Read the topic — open Double Bottom Construction & Deep Tanks for theory, sketches and oral-prep questions.
What's inside this 3D model
- Outer & inner bottom
- Centre girder
- Solid plate & bracket floors
- Bottom longitudinals
- Deep tank & wash plate
About: Double Bottom in 3D
Compare solid plate floors and bracket floors, examine longitudinal framing and explore the deep tank structure.
This free interactive 3D view of the double bottom is built for marine engineers, cadets and seafarers preparing for orals — open it on any device, work through the guided lesson, explore all 5 labelled parts, and then continue with the full Double Bottom Construction & Deep Tanks topic.
FAQs
What does the guided lesson in this double bottom 3D view cover?
The lesson walks you through the double bottom in short steps — Outer & inner bottom, Centre girder, Solid plate & bracket floors 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 double bottom instead of following the lesson?
Yes. Switch the side panel to “Explore freely” for the complete parts list and the model steps for this double bottom. 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 Double Bottom 3D model?
No. The Double Bottom 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 double bottom?
Open the linked topic “Double Bottom Construction & Deep Tanks” below the viewer for the full explanation, sketches, oral-prep questions and related 3D simulations.
