What is PURIGAS (Fuel Gas Supply System)
Catalogue Inquiries

PURIGAS™ is the package solution for Fuel Gas Supply System(FGSS).
It means PURe and Intelligent GAS storage and supply system.

Although FGSS is the most effective solution for IMO’s SOx,
NOx and GHG emissions restriction, CAPEX and installation space are heavy obstacles
to adapt FGSS solution.

To solve this obstacles, PURIGAS™ has been developed from the accumulated
technology for LNG related equipment and engineering capability of S&SYS and
Samsung Heavy Industries(SHI). As accumulated know-how, PURIGAS ™
will provide the most economical and the most reliable package system to customer.

Initial IMO strategy on Reduction of GHG emissions from ships

Level of ambition Timeline

Carbon intensity of ships to decline

  • Strengthening of EEDI requirements for new ships

Short-term measures: 2018–2023

  • EEDI improvement (Energy Efficiency Design Index)
  • SEEMP improvement (Ship Energy Efficiency Management Plan)
  • Speed regulation
  • Methane slip regulation
  • VOC regulation (Volatile Organic Compounds)

Carbon intensity of shipping to decline

  • to decrease 40% CI (carbon Intensity ) by 2030.
  • to decrease 70% CI (carbon Intensity ) by 2050 to decarbonize
    as soon as possible within this century.

GHG emission from shipping to decline

  • 50% reduction of GHG emissions by 2050 relative to 2008

Mid-term measures: 2023–2030

  • Low-carbon/zero carbon fuels introduction
  • Operational energy efficiency requirements
  • Market-based measures

Long-term measures: > 2050

  • Zero carbon/fossil-free fuels for 2050 and late
Reduction ratio of harmful gas by using FGSS

By using Natural Gas Instead of MDO, CO2 is reduced about 23% and SOx, NOx and PM are reduced more than 92%.
