Talusia Optima lube approval
Total Lubmarine’s Talusia Optima lube has now been approved for use by the big three major 2-stroke engine manufacturers.
Talusia Optima has got the go ahead from Winterthur Gas & Diesel (WinGD), Japan Engine Corporation (JEC) and MAN Diesel & Turbo following completion of a successful 8,700-hour sea-trial.
"This was our longest ever trial of a new lube and provides both customers and OEMs with the reassurance that Talusia Optima can be safely used on-board vessels trading for lengthy periods in and out of Emission Control Areas (ECAs),” said Jean-Philippe Roman, technical director, Total Lubmarine.
The sea-trial and comprehensive validation tests were carried out using a combination of Total Lubmarine’s already approved cylinder oils, Talusia LS 25 and Talusia Universal 100.
This allowed for the inspection teams to compare and contrast the performance of the new Talusia Optima product.
The results demonstrated the cleanliness of the engine when used with low and high sulphur fuels in and outside the ECAs and the better efficiency to minimise the liner wear.
Talusia Optima has been designed specifically to facilitate fuel switching when transiting both in and out of ECAs without the need to change lubricants. The lubricant has been designed for use alongside all distillate fuels with a sulphur content of between 0 and 3.5%.
The sea-trials were completed on-board a modern 14,000 teu containership powered by the latest generation fuel-efficient 2-stroke 11S90ME-C mark 10.2 B&W engine, while sailing in and out of ECAs in Europe and Asia.
Talusia Optima is based on an innovative and new type of chemistry known as Ashfree Neutralising Molecules (ANM). The new technology provides effective acid neutralisation, cylinder cleanliness and has the potential to reduce feed rates.
