ECC Concord <strong>Oct</strong>-<strong>Dec</strong> 09 48 Instrumentation Control and Automation plays a crucial role in the safe operation of Jamnagar Refinery which is virtually unmanned. This is achieved by the massive instrumentation works that involve the latest technology available. E & I played a crucial role in executing the critical instrumentation job in the priority areas of one unit of CRUDE-311, and one unit of DHDS-01 and in the non-priority areas which later on turned into a priority area like FCCU, CRUDE-312, ALKALISATION, CFP (DHDS-02, LCO). The scope of instrumentation work involved installation of 4798 junction boxes, 260 instrument panels, 633 t structural steel inclusive Night view of the Project site at Jamnagar Achievements A centralised calibration laboratory with the latest calibration instruments of very high accuracy was set up, which was considered the Model Facility for other instrumentation contractors. In order to meet the high speed of execution the instrument tray routes were finalised based on the 3- D modelling of the units. State-of-the-art Swagelok tube benders were imported for giving flawless bends in impulse tubing works. JB frames were mounted on either dummy wooden sleepers or angle supports taking into consideration the civil elevation before paving. This was advantageous in frame erection much before paving. of fabrication, 221 km GI perforated cable tray, A latest technology called ‘Foundation Field’ (FF) 2311 km of instrument cable, 11089 instrument bus was adapted at JERP. It is an all-digital bicalibration, 10646 instrument installation, 125 directional communication between sensors and km impulse tubing, 17 km GI piping and 10398 the control valves. Special training was given to the loop checking. instrument electricians involved in FF cable laying Similar to the electrical works, the instrumentation and termination works. was also done with 24 staff members of whom 22 On the whole, the quality of work was very much were new. Intensive training was provided to the team appreciated by the spur JB vendor, even members for enabling them to understand the though it was L&T’s maiden venture with the FF systems and to maintain documents. technology. Cable ties of different sizes were used for cable dressing and copper tubing instead of GI wires to avoid damage to insulation. All impulse lines were hydro-tested and proper records were maintained to avoid leakage of hydro - carbon during commissioning. Team L&T is proud to be the driving force behind the installation of such path breaking technology which is considered as one of the technological wonders of the world.

Using RLMS, operation of the Distribution transformers and distribution of In addition to the above benefits RLMS helps the power is automated thereby the load on the significantly in: Transformer and the distribution network is reduced and maintained at optimal level. In the year 2008-09, MESCOM saved 17.92 million units of energy worth Rs. 44.81 million 1. Improved voltage stability 2. Improved power factor 3. Reduced KVA demand due to the implementation of RLMS. 4. Lower overall maintenance cost Rural Load Management System installed in different parts of Karnataka
