Technology Research and Development
ASAC integrates design, R&D, manufacturing and service as a professional mooring chain and accessories vendor. To satisfy the different requirements for chain products from different clients, ASAC carried out extensive research in various parameters such as fatigue, corrosion, stress corrosion, hydrogen embrittlement and abrasion.
ASAC is then able to provide precise solutions to create greater value for users through material design, structural optimization, process research and surface treatment.
ASAC proudly owns the rights to multiple intellectual properties and invention patents for its products and technologies.
Fatigue Test Cases
ASAC carried out fatigue tests on the different grades of mooring chains developed by them using both 1000-ton and 400-ton fatigue testing machines. Results shows that fatigue curves of ASAC mooring chain products were more than twice the average life span of other mooring chain products in the market.
Anti-Corrosion Test Cases
After experimenting with different anti-corrosion solutions and performance tests, ASAC decided to apply heavy-duty anti-corrosion graphene coatings on its mooring chains for corrosion protection. It was found that the anti-corrosion were effective and at the same time, ensuring challenges faced during construction and overall costs reduced for our clients.
Hydrogen Embrittlement Test
Our R&D collaboration with steel mills results in the improvement of resistance against embrittlement of high-grade mooring chains. This effectively reduce hydrogen embrittlement on the chains which benefitted our clients who use these chains regularly on rigs and harsh environments.
