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 watertight doors.
- Use View options — labels, exploded view, pan and full screen are always visible in the toolbar above the model.
- Read the topic — open Watertight Doors: Types, Mechanics & SOLAS Regulations for theory, sketches and oral-prep questions.
What's inside this 3D model

This free interactive 3D view of the watertight doors 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 Watertight Doors: Types, Mechanics & SOLAS Regulations topic.
FAQs
What does the guided lesson in this watertight doors 3D view cover?
The lesson walks you through the watertight doors in short steps — Class 1 hinged door, Class 2 manual sliding, Class 3 power sliding 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 watertight doors instead of following the lesson?
Yes. Switch the side panel to “Explore freely” for the complete parts list and the model steps for this watertight doors. 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 Watertight Doors 3D model?
No. The Watertight Doors 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 watertight doors?
Open the linked topic “Watertight Doors: Types, Mechanics & SOLAS Regulations” below the viewer for the full explanation, sketches, oral-prep questions and related 3D simulations.
