Storm Drain Gate Automation Project – BPCL

In the year 2011: STORM DRAIN GATE OPERATION FOR M/S, BPCL

Problem: The Gates are situated in one of the leading Petrochemical Industries, M/s. BPCL (Bharat Petroleum Corporation Ltd.). The Conventional system used only Chain-Pulley Block for the operation of the Storm gates also known as Nallah Gates. As the plant is situated near the sea shore, it acts as a baffle during High tide, At the same time these gates baffles the oil spillage and crude waste going to the sea and to protect the interest of the people residing around the BPCL Premises.

There are 4 gates having individual Chain-Pulley system. The gates are of Mild Steel of 2.3 mtrs (W) x 2 mtrs(H) x 10mm(T) and weigh 900 kgs approx. guided by Channels duly fitted on the wall from both sides. Ideally it was convenient to operate the gate through conventional system. But following were the problems faced by the User

• The movement of gate was very slow.
• During heavy rainfall or flood, it was difficult to operate the gates even through conventional system due to heavy water pressure.
• As a result, the accumulation of drain water inside the plant can cause a havoc.
• More man power were required.
• No standby system was available except Chain-Pulley system.
• Implementation of the new advanced system without disturbing the existing structure and its process was a big concern.
• As per safety regimen of BPCL, no site welding, cutting etc work was permitted in hazardous area.

Solution: ARHAM had sort out all the above shortfall by introducing full proof Automization system for Lifting the Gates and designed the complete system as per their site conditions as follows:

• New Steel Structure was designed, fabricated and installed without disturbing the old structure.
• Provision of Winch-gear system for individual gates coupled with Electrical Flameproof system (viz: Motor, Panel etc.) resulting in rapid movement of gates.
• Single common Flameproof Panel for all gates with Push Button operations resulting in single man power. Even during flood or heavy rain, the operations of gates are without any hassle. Thus increasing the efficiency of the plant.
• Chain-Pulley system as a stand-by arrangement.
• Provision of Cage Ladder and Platform for ease in accessibility to the system.

ARHAM is very much thankful to M/s. BPCL for having faith and giving the opportunity for complete Designing, Installation & Commissioning of a new era of project for the first of its kind implemented in their premises.
