Berthing Aid Systems
Trelleborg Marine Systems designs and manufactures GPS docking and mooring aids to assist in vessel approach and docking management.
Trelleborg Marine Systems' Offshore Mooring and Docking System (OMADS) is an integrated system that is used to manage the process of docking of a vessel to a floating facility. This includes monitoring the approach, mooring and departure phases. It is used primarily for FPSO and FLNG applications.
OMADS uses the advanced Real-time Kinematic (RTK) GPS technology to provide accurate relative position information to enable vessel operators to monitor the process closely. This minimizes the risk of a mooring incident. The system consists of hardware installed permanently on the primary vessel, and a battery-powered portable unit for the secondary vessel. Information is displayed graphically on both units in either 2D or 3D modes, or both with the auxiliary view. Communication is via UHF telemetry.
- <2 cm accuracy (circular error probability)
- Provides precise information on vessel location, speed and approach angle
- Greatly reduces the possibility of a mooring incident between docking vessels
- RTK GPS is a more accurate system than GPS or DGPS
- No external correction service, such as SBAS, is required
- Multi-frequency receivers reduce the effects of multipath errors
- 3D image gives a better picture of the vessel positions
- Virtual camera enables the mooring process to be viewed from many angles in 3D representation
- Alarms and warnings for approach, docking and moored positions
