PetroChina RHY3532 Marine Cylinder Oil Additive Package Passes MAN Certification

On January 6, 2010, the RHY3532 cylinder oil additive package developed by PetroChina's Dalian Lubricant R&D Center obtained technical certification from MAN B&W, a world-renowned marine engine OEM. This marks that PetroChina Lubricant Company has become the first company in China and the second in the world (after Mobil) able to supply a package for the BOB system used specifically on ocean-going vessels. The successful development and technical certification of the RHY3532 dedicated package not only filled the gap in this technology for domestic oil companies but also demonstrated the technological strength of China's Kunlun brand to the world. The BOB system (Blender-on-Board system) is the world's newest marine technology, designed and developed by Maersk Fluid Technology company (MFT), and is mainly installed on ocean-going vessels. The system can blend marine system oil with a BOB dedicated additive package through automatic control equipment into cylinder oil with any target base number, offering clear advantages in energy saving and environmental protection. The Dalian Lubricant R&D Center closely followed the development trends of world marine technology and targeted the needs of the international shipping market, starting R&D work on a dedicated cylinder oil additive package for the BOB system as early as the beginning of 2008. Over two full years, it overcame a series of difficulties including the high cost of foreign ultra-high-base-number detergents, foreign technology blockades and the unstable performance of domestic ultra-high-base-number detergents. Through technical cooperation with domestic additive plants and the redesign and optimization of the cylinder oil formulation, it finally arrived at a formulation with a treat rate far lower than that of the original cylinder oil package, greatly reducing product cost. On May 4, 2009, the RHY3532 package began use tests on a MAN B&W 12K90MC marine engine of Maersk. After nearly 4,000 hours of voyage testing, a final cylinder inspection was carried out on November 23, 2009, with all engine data normal, proving that the package performs well and smoothly obtaining MAN B&W certification. In today's increasingly internationalized marine lubricant technology environment, Kunlun Lubricant closely follows the development of marine engine OEMs and shipping companies and has gained their technical approval, which will certainly have a positive and far-reaching impact on seizing the international marine oil market.
