Leading edge electronics systems developed by Incat monitor all aspects of Incat vessels. Service and after sales support is aided by an integrated computer system, where all on-board ‘processor’ computer based systems are networked to a dedicated Incat Service computer. The system allows on-board or remote analysis of all-important, historical and real time operational data by Incat service technicians to assist in fine-tuning and fault finding of control and monitoring systems. In addition to “state of the art” monitoring systems like SIMS and VDR, a major support tool is a diagnostic system appropriately named VISIT (Vessel Information Systems Interactive Telemetry). VISIT allows Incat technicians to review operational features on craft regardless of where they are in the world, and even to re-configure where necessary. Dynamic data can be taken and stored on craft whilst they are in service and later transferred to Incat for R&D or new design projects. These integrated diagnostic systems ensure a fast comprehensive identification and attention to service matters and operational related technical issues.
