SUPERVISORY CONTROL AND DATA ACQUISITION SYSTEMS FOR OFFSHORE VESSEL NAVIGATION

摘要

A Supervisory Control And Data Acquisition (SCADA) system guides navigation of a vessel (100) enabled to extract energy from wind and/or water currents primarily in offshore marine environments. An exemplary SCADA system (102) embodies server and client software applications running on microprocessor systems (200, 204, 209) at a remote control central service logging and energy distribution facility, and the vessel itself. The central server accesses geographic information to track vessel position, e.g. based on transmitted Global Position Satellite (GPS) data (202) from the vessel. The central server further accesses performance models for velocity and energy efficiency of the vessel. Another SCADA system provides offshore vessel navigation. It analyzes cost of paths based on performance models of the vessels and communicates data guiding navigation to the vessels to avoid high cost paths.
