Dynamic positioning (DP) is a computer-controlled system to automatically maintain a vessel's position and heading by using its own propellers and thrusters. Position reference sensors, combined with wind sensors, motion sensors and gyrocompasses, provide information to the computer pertaining to the vessel's position and the magnitude and direction of environmental forces affecting its position.

As a Dynamic Positioning Operator (DPO) I work on the ship’s bridge which is the control centre of the ship. I report to and work under the direction of the ship’s master. Our vessel operates on the Grand Banks of Newfoundland. We transport oil produced by the different offshore production platforms and bring them to market. We sail between Newfoundland, Eastern Canada, and the Eastern United states. I work as part of a team to make sure we follow environmental regulations to prevent possible spills or other accidents.

DP is a computer controlled system that records the vessel’s position and heading. It also collects data from various sensors (e.g., wind sensors, motion sensors, and gyrocompasses) to show where the vessel is. When working near other ships or structures, the DP shows where the ship is in real time. This is important because the vessels I work on can be over 200 metres in length and weigh over 100,000 tonnes. I’m responsible for monitoring the safe day to day operations of the vessel and keeping watch during navigation at sea. I use the DP information to take corrective actions when necessary. I also work to maintain the vessel’s firefighting and lifesaving equipment.
