Every ship transporting goods to, from or through the Arctic wants to find the fastest and safest way through or around the ice. Even service ice breakers save considerable amounts of time and fuel when they choose an easy path through the ice opposed to a straight path.

Maritime pilots work in an irregular deployment system (rotation system) with unpredictable work assignments under high levels of physical and mental stress. Fatigue or chronic diseases, e.g. coronary heart disease, peptic ulcers or gastritis can occur as a consequence.

Training video VI on the correct use of the pilot ladder

Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal can easily fail.
