Floating roof tanks

JPM is designing and building floating roof tanks (with and without steel cup) for all applications and storage products. Here, the different requirements and design parameters are taken into account such as:

  • Design codes: EN, EEMUA, DIN, API, ASTM, ASME, BS, Codres, etc.
  • Applications: chemicals, petroleum
  • Material: carbon steel
  • Temperature range: from -20 °C to +100 °C according to customer requirements
  • Design pressure: atmospheric
  • Specific gravity: of less than 1000 kg/m³ to 2,000 kg/m³ and heavier
  • Sizes: up to large storage tanks with 100,000 m³ content and more
  • Tank bottom: full overlay flat bottom overlapped or butt welded, performed with and without gradient
  • Floating roof: pontoon floating roof with centre pontoon and double-deck floating roof, each equipped with the JPM floating roof seal SWING I

The necessary safety equipment for trouble-free operation of different operating applications are selected and designed by our engineers according to the relevant standards:

  • Spray system as a cooling system for protection against fires of neighbouring structures
  • Foaming system as a fire extinguishing system for fighting fires
  • Different internal and external heating systems to control the temperature of the stored products
  • Over-and under -pressure devices to provide protection against pressure damage
  • Overfill prevention (High Level, Low Level)
  • External inspection facilities e.g. stairs, ladders, platforms, etc. to ensure safe accessibility of safety- and operating-equipment as well as measurement devices.
  • Facilities for inspection of the tank interior such as manholes and cleaning openings
  • Roof and tank shell nozzles for different applications and in various designs e.g. double-walled
  • Equipment for leakage monitoring of tank bottom and tank shell.
  • Tank anchorages according to the designed pressure range and the applicable seismic loads and in accordance with the available foundations
  • Additional equipment required for the safe operation e.g. inlet pipes, dip pipes, floating suction units, skimmers, etc.
