Artemis: Microwave Position Reference System for Dynamic Positioning
In Dynamic Positioning (DP) operations, Artemis is a specialized position reference system that employs microwave technology to provide precise range and bearing data. This system consists of two key components: a shore-based transceiver and a shipboard transceiver, working in tandem to maintain accurate positional information.
How Artemis Works
Artemis operates by establishing a microwave communication link between the transceivers. The shore-based unit acts as a stationary reference point, while the shipboard transceiver continuously exchanges signals with it to calculate the vessel's position. The system determines the vessel's range (distance from the reference point) and bearing (angle relative to the reference point).
Key Advantages of Artemis
- Reliability in Challenging Environments: Artemis is well-suited for use in environments where other positioning systems, such as DGPS, might be less effective due to signal obstructions or interference.
- Independence from Satellite Signals: Unlike GPS-based systems, Artemis does not rely on satellite coverage, making it a robust alternative in areas with limited or disrupted satellite signals.
- High Accuracy: The microwave technology ensures precise and consistent position data, crucial for sensitive offshore operations like drilling, subsea construction, and wind farm installation.
Applications of Artemis in Dynamic Positioning
Artemis is widely used in industries requiring high-accuracy position reference data. Common applications include:
- Offshore oil and gas platforms
- Floating production storage and offloading (FPSO) units
- Cable laying and subsea installation vessels
The system's ability to provide dependable position data even in adverse conditions makes it a trusted choice for maintaining station-keeping in critical offshore operations.
