KC-1 AT THE FOREFRONT OFWORLDWIDE SHIPPING TECHNOLOGY

We KC LNG Tech were founded in February 2016 by Korea Gas Corporation(KOGAS) and three domestic shipbuilders (HHI, SHI and DSME) to commer-cialize KC-1 which is the cargo containment system(CCS) for LNG carriersthat was developed in Korea.We at KC LNG Tech are providing the LNG CCS & CHS design service, con-sultancy and engineering.50 patents related to the KC-1 LNG CCS have been registered in Korea, EU,USA, China, Japan and Australia and the uniqueness and originality of its tech-nology was verified through the leading Classification Societies.As the first step to enter global LNG market, it has been applied to two shipsoperated by SK Shipping scheduled to deliver end of 2017.KC LNG Tech plans to continue R&D to increase operational efficiency, safetyand competitiveness.We expect your continued interest in KC LNG Tech and look forward to a re-warding business relations with you.Thank you

GLOBAL LEADING COMPANYTO OPEN BRIGHTER FUTURE

KC LNG Tech intends to become the best engineering company in cargo containmentsystems for LNG carriers and will lead the way to a brighter future through passion andknow-how to realize the value of creating a deep impression on customers.

• The insulation system minimizes the effectof ship deformation since it is not in contactwith the ship

• The productivity is increased by straight linewelding of membrane

• The large membrane panel installation ismore efficient using the MSS (Moving Scaffolding System)

• Single-layered insulation panel with excellentthermal isolation

• The secondary barrier provides complete sealing

Result of KC-1 SystemFE Analysis

In 2004, a project was launched in order to develop a unique membrane type CCS forLNG carrier by employing KOGAS(Korea Gas Corporation)’s membrane technology ap-plied to ground LNG storage tanks. After 10 years of research and development, KOGASand the three major shipbuilding companies in Korea successfully completed KC-1 sys-tem in 2014. The commercialization of KC-1 will be an oustanding model to offer uniquecompetitiveness and stability.

• Insulation Panel(IP) is a bonded sandwich structure with onlyone layer including back plywood, rigid closed cell foam paneland top plywood

• Uses PUF insulation instead of R-PUF• Excellent thermal isolation (thermal conductivity approx. 10%

System & FacilitieS

MOST ADVANCED SYSTEM IN TERMS OF WORKABILITY, PRODUCTIVITY AND ECONOMICS

Moving Scaffolding System(MSS)

Longitudinal rail• Rail for movement along longitudinal direction• Rail guide fastened to the thick plate with bolts• The guide fixture is welded to the thick plate at the shop

Moving rail• It moves along the tank length through the longitudinal rail, and the membrane

carrier moves in the circumferential direction along the rail inside the truss• It consists of low chamfer rail, vertical rail, upper chamfer rail, and ceiling rail• They are separately fabricated in 2~3 stages to make installation easier and

assembled on site• Each moving rail can move individually

The technique for automatic systems has been constantly researched for improve-ments. By applying Moving Scaffolding System and automatic welding system, pro-ductivity could be increased and construction period could be reduced.

• Duration reduction : Transfer and install the membrane panel efficiently• Work flow : supply membrane→membrane installation→ return carrier• Available in overhead, vertical and horizontal installation

Longitudinal railMembrane carrier

Membrane carrier• Move the membrane panel to installation location• Truss structure with rectangular pipe• Moving along the moving rail using the roller in each of 4 corners• Fixing system for the membrane panel• Jack and fine adjusting clamp for installation
