Differential GPS (DGPS) is a position reference system that enhances the accuracy of the Global Positioning System (GPS) by incorporating correction data from fixed reference stations. Widely used in Dynamic Positioning (DP) operations, DGPS provides precise positional data, making it indispensable for offshore and maritime industries.
Dead Reckoning Mode is a fallback operational mode in Dynamic Positioning (DP) systems, activated when all position and/or heading references are lost. In this mode, the DP system uses onboard sensors and mathematical models to estimate the vessel's position and heading, ensuring some level of control and stability until references are restored.
Cyscan, developed by Guidance Navigation, is a laser-based position reference system widely used in Dynamic Positioning (DP) operations. This advanced system provides precise positional data, ensuring reliable station-keeping in challenging offshore environments.
A Controllable Pitch (C.P.) Propeller is a type of propeller designed to allow the adjustment of the blade pitch angle to regulate the magnitude of thrust. This functionality provides precise control over vessel maneuvering and power efficiency, making it an essential component in many modern maritime operations, especially those involving Dynamic Positioning (DP) systems.
Consequence Analysis is a critical function in the Dynamic Positioning (DP) software required for vessels operating under Equipment Classes 2 and 3. This advanced feature continuously evaluates the vessel's ability to maintain position and heading after a worst-case failure (WCF) scenario, ensuring operational safety and compliance with international standards.
Common Mode Failure (CMF) refers to a situation where multiple elements within a redundant system fail simultaneously due to a shared cause or factor. In Dynamic Positioning (DP) systems, which rely on redundancy for reliability and safety, CMF is a significant concern as it can undermine the very safeguards designed to prevent total system failure.
The Center of Rotation (CoR) is a designated reference point within a vessel around which it rotates while operating in full automatic positioning mode. This parameter is crucial for the effective control of a vessel's movement and stability, especially in Dynamic Positioning (DP) operations.
Catastrophic failure refers to a system failure so severe that it results in the complete loss of the vessel’s ability to maintain its position and/or heading. In the context of Dynamic Positioning (DP) operations, such failures pose significant risks, especially in high-stakes offshore environments where stability and precision are critical.
A Bus Tie Breaker is an essential device used in electrical systems to connect or isolate individual sections of a switchboard. In maritime and offshore operations, particularly in vessels equipped with Dynamic Positioning (DP) systems, bus tie breakers play a critical role in ensuring power distribution reliability and flexibility.
An Azipod unit is a specialized type of azimuth thruster that integrates the propulsion motor within a streamlined pod. This design enables the thruster to deliver efficient and highly maneuverable propulsion, making it a preferred choice for various vessel types and offshore operations.
