This involves a number of the manufacturer’s engines when operating on a wide variety of fuels from 1.5% to 3.5% sulfur, including fuels compliant with emissions control area (ECA) regulations with a maximum content of 0.1% sulphur, therefore removing the need to change cylinder lubricants when operating in and out of ECAs.
This follows 6,000 hours of validation testing on board a Panamax containership fitted with a Wärtsilä 8RT-flex82T engine. Taro Special HT 100 was specifically formulated for high performance and demonstrated enhanced performance in distillate fuel applications under laboratory engine conditions.
The NOL applies to the use of the lubricant in WinGD X, WinGD X-DF, WinGD RT-flex, WinGD RT-flex-DF, Wärtsilä RTA, Wärtsilä RT-flex and Wärtsilä X engines, as well as in Sulzer 2-stroke engines, that are operating on bunker fuels with a sulfur content ranging from 1.5% to 3.5% and intermittent use with fuels compliant with ECA regulations with a maximum sulfur content of plus or minus 0.1%.
Chia Yoo Soon, Chevron Marine Lubricants general manager, said: "We are delighted with the results of the testing and to receive this No Objection Letter from Winterthur Gas & Diesel. It is further evidence of how Chevron Marine Lubricants is helping shipowners and operators reliably navigate the ECA requirements of today and is ready to meet the challenges of tomorrow as shipping moves into a lower sulphur, lower emissions future."
Konrad Räss, WinGD’s general manager combustions systems, commented: “As a leading developer of marine low-speed gas and diesel engines our target is to set the highest possible industry standards, a philosophy that is echoed throughout our rigorous testing regimes. After 6,000 hours of sea-trials, Taro Special HT 100 has shown that it meets the exacting standards demanded by WinGD and we have no hesitation in providing this No Objection Letter as a result.”
