Тип теста: STCW.
Должность: 3rd Officer.
Уровень: Operational.
Область: Navigation.

В процессе отбора и набора персонала, а также для измерения уровня знаний существующих офицеров и экипажа, CES тест хорошо показал себя по всем параметрам. Ocean Technologies Group использовали для создания вопросов обширные темы, которые включают:

Управление кризисными ситуациями и скоплением людей;
Интегрированная навигационная система;
Управление балластными водами;
Обработка и укладка грузов;

The collision regulations are based on ship courses through the water.

The true vector can never give an indication of collision risk with another ship.

The Relative Motion display and relative vectors is the only display to use for anti-collision purposes.
