In DP3 operations, the real question is simple:
What happens when a controller fails, or a sensor starts lying – and you are still on DP?

Praxis Automation has been selected by Sinoship Maritime Services to deliver a fully integrated upgrade for Bourbon Evolution 801 and 803 – combining a next-generation DP3 system with Vessel Management (VMS), Power Management (PMS) and Thruster Control (TCS).

At the core is the Mega-Guard DP3 architecture, built around triple DP controllers, segregated I/O and three independent communication networks. Operator stations and control domains are physically and logically separated so that loss of any single controller, HMI or network segment does not compromise DP capability.

The new DP3 will interface with the existing power plant and switchboards, working hand-in-hand with PMS and VMS to support split-bus – and, where class-approved, closed-bus – operation. Blackout prevention, ride-through and recovery are engineered according to a worst-case failure philosophy and validated via class-approved FMEA and proving trials.

Because these are existing DP3 hulls, retrofit risk is treated as a design topic, not an afterthought. Existing switchboards, sensors, legacy I/O and selected cabling are reused where they meet current standards, with clear interfaces to third-party systems and a stepwise commissioning plan from FAT to HAT and DP trials to minimise downtime.

Cyber security hardening, secured remote access and controlled data flows are part of the baseline design. Hot spares at controller and HMI level enable fast failover without loss of situational awareness, while global and regional service hubs provide lifecycle support, remote diagnostics via Internet Ship View and upgrade paths as offshore requirements evolve.
