Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
For DP class 2 or 3 systems in open water, typical accuracy is ±0.5 to 2 meters. Actual accuracy depends on the specific system configuration, environmental conditions, and sensor quality. Always verify with the manufacturer for your application.
The system can typically operate in wind speeds of 20–40 knots and significant wave heights of 3–6 meters. These are reference ranges; the actual capability depends on the vessel's thruster power and DP class. Confirm with the supplier.
Key standards include IMO MSC.1/Circ.1580 for DP class redundancy, IEC 60038 for power supply voltage and frequency, IEC 60945 for temperature ranges, and IEC 60529 for ingress protection. These are verification references, not proof of compliance.
The system uses thrusters and propellers to counteract environmental forces. It continuously monitors position and heading via GPS, DGPS, and other sensors, and automatically adjusts thruster outputs to keep the vessel within set tolerances. This allows precise station-keeping without traditional anchors or mooring lines.
