What you’ll learn

  1. Build a floating cityExplain how Harland and Wolff transformed plans, steel, labor, and shipyard infrastructure into a launched liner.Titanic grew from a keel and frames into a fitted-out ocean liner through staged industrial work.
  2. Design buoyancy and limitsConnect Titanic's hull, machinery, luxury systems, compartments, and lifeboat rules to the limits of safety design.The liner combined advanced systems with assumptions about damage, evacuation, and regulation.
  3. The collision opened a chainTrace how visibility, speed, iceberg impact, material behavior, flooding, and wireless communication interacted.The collision became a disaster through a chain of physical damage and delayed rescue constraints.
  4. Why the ship sankExplain progressive flooding, changing trim, structural breakup, evacuation limits, and the evidence from the wreck.Titanic sank when flooding overwhelmed reserve buoyancy, then altered the hull's loads and the evacuation problem.

Questions this course answers

What did launching Titanic accomplish?

Launch created a floating hull; engines, interiors, electrical systems, and other equipment still had to be installed.

Why were frames and plates important together?

The internal skeleton and outer steel shell worked as a connected structure.

What was the purpose of watertight bulkheads?

The compartment system bought survival time, but it had limits on how many spaces could flood.

Why were lifeboats a separate safety problem?

Lifeboats help people survive abandonment; they do not stop flooding or keep the ship afloat.

Why did the calm, moonless sea matter?

Low contrast and a smooth sea made the iceberg harder to detect in time.

What turned the collision into progressive flooding?

Several forward spaces flooded, and the changing trim allowed water to pass over bulkheads.
