Science helps in study for a career at sea
Deirdre O'Neill is studying for something she says is "a pretty big job". That role is chief mate / master on a ship, one rank below captain.

During her course at the National Maritime College of Ireland (NMCI) in Cork, Deirdre learns about many aspects of ships and sailing. A lot involve science and technology, such as:
  • Ship stability and how to load a ship safely
  • Ship construction
  • GPS (global positioning system), the worldwide radio navigating system
  • Radar, the science of detecting distant objects and determining their position, speed or other characteristics by analysing radio waves reflected from their surfaces
  • Echo sounders, which measure water depth. An echo sounder emits an ultrasonic pulse that is reflected from the seabed. The time between sending the pulse and receiving the echo is a measure of water depth
Simulator

It's not all about the classroom, though. Sometimes Deirdre and her classmates use a simulator, which is an accurate replica of a ship's bridge.

The simulator is very flexible. It can be programmed, for instance to:
  • Go anywhere in the world
  • Take on the characteristics of any type of ship
  • Recreate a wide range of environments
When SCOPE met Deirdre, she was simulating sailing a 10,000-tonne passenger liner into Sydney Harbour.

Career

So where did Deirdre's nautical career begin?

She says: "This is what I've always wanted to do, probably since I was about 12 when I joined the sea scouts. Then I took it a step further. I went on the Asgard II when I was 16. After that trip I decided to make a career of it."

Deirdre began her studies in the Cork Institute of Technology (CIT) where she studied nautical science. This is a three-year course, two years in college and one at sea. "At that stage I was sailing as a cadet so I was basically learning everything on a ship," she says.

Tall ships

Sailing tall ships is Deirdre's favourite part of the job. She says: "It's fun and you meet new people all the time. When I finish here I'll be qualified to work on all kinds of ships - tall ships, tankers, container ships..."

But first of all, Deirdre needs to find a space in Sydney Harbour to park that liner.
