Emergency Release Systems

ERS

Part of high technology safety devices designed and developed by FMC Technologies are Emergency Release Systems (ERS) that enable a rapid disconnection of Marine Loading or Truck and Railcar Loading Arms from the vessel in case of an emergency such as fire on board, excessive drift of a tanker or for a truck accidentally moving away from the operating area.

FMC Technologies has a large range of field proven reliable Emergency Release Systems (ERS) to meet any oil, gas, chemical, petrochemical or other fluid transfer application. The development of these systems started in 1967 when FMC patented the first Powered Emergency Release Coupler (PERC). Since then FMC has supplied a variety of systems for offloading of fluids be it at jetties of for truck and railcar installations. For exposed locations and other offshore terminals that subject tankers to larger movements, ERS systems have become a must together with multi-stage electro/hydraulic systems to enhance the safety of the installation and ensure continuation of offloading operations.

Truck and Railcar Breakaway Couplers
Features
  • The ERS system is composed of two isolating valves installed on either side of the PERC
  • There is a choice of valves to meet the product handled specific requirements of each terminal. The volume of fluid to be spilt between the two valves can also be critical in the choice of valves particularly for toxic products, LNG etc.
  • A multi-stage alarm system is linked to the logic control system to ensure that the product pumps are stopped and that the two isolating valves are shut prior to the opening of the PERC and the arm automatically manoeuvred away from the tanker manifold flange
  • The PERC is in stainless steel and is spring energized to ensure immediate disconnection
Benefits
  • Reduces the risk that the offloading equipment be damaged resulting in downtime and possible demurrage charges for the vessels
  • Reduces product spillage and enhances overall safety of the operators and of the installation
  • Field proven highly reliable reducing maintenance and downtime of the equipment
