KC CCS

Leap toward Global Market

  • New membrane cargo containment system adopting membrane technology of onshore LNG storage tank developed from 2004 through 2015
  • Class approved AIP(Principle), DA(Design) by ABS, KR, BV, LR and DNV
  • Total 40 patents are registered in South Korea, EU, China, Japan, USA, Australia and etc
  • CCS Design/Testing Technology acquisition in 2015
KC CCS

Main Concept of KC CCS

  • Membrane type CCS using adjacent double metal barriers
  • Enhanced gas tightness at primary and secondary barrier
  • Prevent thermal shock caused by cryogenic temperature and minimize pressure rise caused by vaporization in case of LNG leakage on the 1st barrier
  • Easier to manufacture and install by simplifying one layered insulation
KC-1 layer structure

Membrane Panel

Consisting of 1st and 2nd membrane made of SUS 304L with non-continuous corrugation

Membrane Anchor

Used to fix parts of membrane to the insulation panels

Insulation Panel

A bonded sandwich structure with an only one layer including back plywood, polyurethane foam and top plywood

Inter Barrier Spacer(IBS)

Maintaining regular distance between primary and secondary membrane , which doesn’t have an influence on secondary membrane in case of the damage on primary membrane

Corner Fixture

Consisting of wing plate and base plate to make corner panel fixed to hull

Thick Plate

Fixed to corner fixture and functioning as a structure

KC-2, Enhanced Version of KC-1

KC-1 KC-2
Primary Barrier Stainless 1.5mm
(non-continuous corrugation)		 Stainless 1.2mm
(non-continuous corrugation)
Secondary Barrier Stainless 1.5mm
(non-continuous corrugation)		 Stainless 1.2mm
(non-continuous corrugation)
Insulation Panel PUF R-PUF
174K LNGC BOR (Thickness) 0.12 %/day (256.5mm) 0.07 %/day (450mm)

Improved Features of KC-2

  • Easy to manufacture by simplifying the structure of Membrane Anchor
  • Enhancing solidity with a change to R-PUF
  • Improving BOR by increased thickness in R-PUF
  • Improving BOR and making it easier to manufacture by eliminating heavy structure in Corner Panel
  • Blocking thermal flow by improving the structure of Insulation Panel
