Description
1. Product Overview
KONGSBERG RCU602 is a high‑performance Remote Controller Unit developed by KONGSBERG for marine and offshore engineering applications. It serves as the core real‑time process control computer for the K‑Chief 700 vessel automation system, K‑Safe safety control system and cJoy manoeuvring control system. Adopting an embedded Power‑PC‑architecture processor, it delivers high‑speed computation, real‑time response and high‑reliability processing capability, acting as the central computing and control hub for complete vessel engine‑room automation, dynamic positioning, condition monitoring, logic control and equipment interlock systems.
The RCU602 supports multi‑redundant topologies including standalone, dual‑unit and triple‑unit configurations, flexibly catering to low‑, medium‑ and high‑level marine safety‑control scenarios and eliminating single‑point‑failure risks in marine industrial‑control systems. Equipped with dual‑Ethernet process networks, dual redundant control networks and dual field‑bus interfaces, it features independent data computation, logical judgement, equipment regulation, fault diagnosis and data‑exchange functions. It centrally acquires operating data from engine‑room power equipment, navigation apparatus, propulsion systems and environmental‑monitoring devices, and executes automation‑control logic, interlock protection, parameter adjustment and system interlocking commands. Designed in compliance with classification‑society marine certification standards, it offers outstanding resistance to vibration, humidity‑heat, salt‑spray and electromagnetic interference. Suitable for harsh offshore conditions such as ocean‑going vessels, offshore platforms and near‑shore engineering units, it is widely deployed for automation outfit on new‑build vessels, K‑Chief system upgrades for existing ships, faulty‑controller replacement and control‑system retrofits for offshore installations. It ranks among the most versatile and reliable core control modules within marine automation.
2. Functional Features
2.1 High‑performance Real‑time Computation for Precise Vessel‑automation Control
Featuring an industrial‑grade embedded dedicated Power‑PC processor with high‑speed floating‑point arithmetic and real‑time task scheduling optimized for marine dynamic‑process control, the RCU602 responds to equipment‑control commands within millisecond intervals. It accurately implements logic computation, parameter tuning, closed‑loop control and interlock protection for engine‑room power systems, propulsion systems and auxiliary systems. It processes massive vessel‑condition data in real‑time to avoid control lag, logic disorder and data stalling, ensuring precise automatic operation of critical assets including main engines, auxiliary engines, pump sets, valves, thrusters and positioning equipment, and providing core computing support for navigation safety and stable equipment performance.
2.2 Multi‑mode Redundant Architecture for Zero‑downtime System Operation
The module natively supports three topological configurations: standalone operation, dual‑unit hot‑standby redundancy and triple‑unit fault‑tolerant redundancy. Redundancy schemes can be selected according to vessel DP (Dynamic Positioning) class and safety‑system requirements. Under dual‑/triple‑unit redundant modes, multiple RCU602 units run in parallel with real‑time data synchronisation and load balancing. If one controller suffers failure, power loss or communication breakdown, the redundant unit takes over all control tasks seamlessly without delay. Control continuity, operational‑data integrity and equipment runtime are fully preserved, satisfying stringent 7×24‑hour non‑stop‑operation requirements for high‑safety‑class ocean‑going vessels and offshore platforms, and eliminating single‑point‑failure vulnerabilities of conventional single‑controller architectures.
2.3 Dual‑redundant Multi‑bus Interfaces for Stable and Reliable Data Transmission
Incorporating multiple sets of industrial‑grade dual‑redundant communication interfaces: dual‑redundant Ethernet LAN process networks, dual dedicated RCU redundant control networks and dual redundant field‑bus interfaces. It simultaneously connects to engine‑room I/O modules, human‑machine operating terminals, supervisory host systems, navigation devices and power‑control units. Parallel multi‑link transmission with mutual backup prevents data disconnection, command loss and system offline status caused by single‑link breakage or interference. It seamlessly interoperates with the full K‑Chief automation portfolio, cJoy manoeuvring‑control systems and vessel DP dynamic‑positioning systems to realise ship‑wide data exchange, equipment interlocking and centralised supervision, delivering excellent networking compatibility and anti‑interference performance.
2.4 Full‑scope Fault Self‑diagnosis and Interlock Protection
Comprehensive hardware‑, software‑ and link‑oriented self‑diagnosis continuously monitors processor status, power‑supply conditions, bus communication, I/O links, program execution and system clock. It accurately identifies module faults, circuit anomalies, communication outages and program exceptions. Upon fault detection, it triggers alarms, latches fault status and uploads fault codes, while executing pre‑configured safety‑interlock logic to mitigate risks of equipment mal‑operation, runaway and over‑range operation. Fault data is stored for traceability to facilitate rapid troubleshooting by on‑board technicians, reducing unplanned downtime and navigation‑safety hazards.
2.5 Light‑weight Modular Design for Convenient Installation and Replacement
Built as a standard marine‑grade modular unit for DIN‑rail mounting inside KONGSBERG‑standard cabinets, it features compact dimensions, tidy wiring and simple assembly‑disassembly. Hot‑swap whole‑unit replacement is supported without rewiring or logic modification, shortening vessel‑repair and lay‑up duration during retrofits and faulty‑unit exchange. On‑board visual LED indicators display operational status, communication health, fault conditions and redundancy‑synchronisation status for quick on‑site assessment and simplified routine inspection and troubleshooting. Secure remote firmware upgrade is available, enabling functional optimisation without module disassembly.
2.6 Marine‑grade Reinforced Protection for Harsh Off‑shore Conditions
Designed to top‑tier offshore‑engineering protection standards and validated by rigorous marine tests covering vibration‑shock, salt‑spray corrosion, damp‑heat ageing, EMC and thermal cycling. It delivers excellent anti‑vibration, anti‑shock, salt‑spray‑resistance, moisture‑corrosion‑resistance and EMI‑immunity. It withstands harsh ocean‑going conditions including high humidity, heavy salt‑spray, persistent hull vibration, wide temperature fluctuation and intense on‑board electromagnetic interference. With low hardware failure rates, it enables long‑term maintenance‑free stable performance and meets year‑round non‑stop operational demands of vessels and offshore platforms.
