Recently, China Classification Society (CCS) Guangzhou Branch
has successfully completed the supplier certification for Zhong Xing Sea-land Engineering
Co., Ltd. for conducting primary and secondary barriers tightness testing of
membrane enclosure system for gas tankers in operation. On April 10, 2024, Han
Xuechao, Deputy General Manager of Guangzhou Branch, issued CCS’s first global certificate
of approval to Zhong Xing Sea-land Engineering Co., Ltd.
The tightness testing
technology is widely applied in the liquid cargo tanks of membrane LNG
(liquefied natural gas) tankers, membrane liquid cargo tanks of LNG fuel
refueling ships, membrane LNG land storage tanks, membrane LNG fuel tanks of
large green energy ships (such as large container ships, oil tankers, etc.),
etc. The entire testing process is monitored and analyzed in a real-time manner
through intelligent digitization, which makes on-site testing more efficient
and safe, providing safety and quality assurance for the production and
transportation of green energy such as LNG.
In recent years, CCS has been concerned about new quality testing
technologies represented by green and intelligence, actively cooperated with
relevant domestic departments and enterprises, and continuously launched
application guidelines for new technology maintenance and testing services. In
October 2023, CCS issued relevant certification requirements to the shipping
industry for “suppliers of primary and secondary barriers tightness testing for
membrane enclosure system of gas tankers in operation”.
