Most modern DP control systems only directly measure and compensate for one of the external forces that moves the vessel. Wind is measured and compensated for, but water current, wave slap, and forces from coupled bodies usually aren’t.  ...

Dynamic positioning may be defined as "A system that automatically controls a vessel to maintain her position and heading exclusively by means of active thrust". A DP-capable vessel must have a combination of power, manoeuvrability, navigational ability and computer control in order to provide reli ...

Measurements of a vessel's position and heading at any point in time are essential for dynamic positioning. Several different position-reference systems are normally used with the SDP system. The first position-reference system selected and accepted for use with the SDP system becomes the referenc ...

Most dynamic positioning (DP) control systems require three but some don’t. This is why many classification society (class) rules only required two. Let’s look at why most systems need three and how three is sometimes one. /p> ...

There are different types of position reference sensors that work on different principles. They all determine the position of the sensor from reference points. Sensors that are dependent on the same signals through the same medium have common failure modes and are not independent /p> ...

For equipment class 3, the main DP control system should consist of at least two computer systems arranged so that, in case of any single failure, automatic position keeping ability will be maintained. /p> ...

A system of lights and audible alarms should indicate the DP system status at the appropriate operational/control locations. The required responses to a change in alert level should be determined by risk assessment and documented in tabular format in the ASOG. /p> ...

In today's industrial landscape, safety is of paramount importance. One area that requires special attention is hydrogen sulfide (H2S) safety. To enhance your safety knowledge, it's essential to take an OPITO H2S course. /p> ...

The maritime industry is an essential part of global trade and transportation, connecting nations and facilitating economic growth. However, it is also an industry that presents unique risks and challenges. /p> ...

What is Maritime Security? Many people understand maritime security to be the role of the military to protect our seas and oceans, but this is not always the case. /p> ...
