Control System Design
 RFA AOR Class Retrofit
In co-operation with our partner Lyngso Marine, Bond Instrumentation can offer a range of control and monitoring equipment for marine applications. Using the standard Lyngso building block basis a control system can be designed to meet customer specifications for new buildings, conversions and retrofits. Where equipment is required to replace obsolete relay based logic systems Bond can offer alternative approved P.L.C. equipment to provide the same functions with reduced space requirement, lower power drain and increased reliability.
The remote electronic control for a B & W KLM80 main engine was found to be obsolete and beyond economical repair. A replacement P.L.C. based system was designed by Bond Instrumentation and approved/tested by the Classification Society in under four weeks. The system was installed on the vessel during alongside cargo discharging and extensive sea trials confirmed all control functions were as per specification.
An existing electromechanical relay system for remotely controlling eight diesel generator sets was obsolete and unreliable. Using an approved P.L.C., Bond Instrumentation designed, built, installed and commissioned a replacement equipment which required around 50% less space and used 20% less electrical power. Each machine has its own dedicated P.L.C. which provides control and safety functions, a common P.L.C. monitors the overall system and ensures the power demand is met when required.
The main propulsion C.P. propeller control system was found to be obsolete and beyond economical repair, Bond Instrumentation designed, built, installed and commissioned a replacement P.L.C. Based system.
A fire caused extensive damage to the control equipment and cabling in the engine room of an offshore supply vessel. Bond Instrumentation designed, built, installed and commissioned a replacement control and monitoring system during the eight weeks the vessel was alongside for repairs. In the same period the pneumatic controls for the four propulsion engines were overhauled and checked with all systems thoroughly tested during extensive sea trials.
A replacement eight hundred point control and monitoring system was designed, built, installed and commissioned by Bond Instrumentation for RFA Argus for the UK Ministry of Defence.
The cargo pneumatic pumping controls on a 30,000 dwt oil products carrier had become inoperable due to salt atmosphere corrosion and unsupportable equipment. Bond Instrumentation supplied, installed and commissioned a new console with updated control equipment and increased protection against the salt atmosphere corrosion.

A BOND Retrofit makes it plain sailing for RFA AOR Class Vessels

MACHINERY CONTROL AND SURVEILLANCE SYSTEM
Using the latest industry standard PLC from the Allen Bradley ControlLogix range a replacement 5000 I/O distributed system has been designed and built by the Bond Instrumentation team for the AOR class of vessels.

Constructed and installed to Lloyds standards the system has undergone extensive environmental testing.

20 Outstations are located around the vessel, fitted with heavy duty shock mounts.



Communication between outstations and workstations is via dual redundant fibre optic Ethernet and Controlnet. 9 Workstations using TFT technology are located in the 4 control rooms including the bridge.
