Total Lubmarine obtains two no objection letters from MAN

Lubricant supplier Total Lubmarine announced on Thursday that it has received two no objection letters (NOL) from equipment manufacturer MAN Diesel and Turbo in recognition of the effectiveness of two of its products.

The first NOL is said to recognise "the excellent performance" of its Talusia HR 140 cylinder oils, approving it for use in MAN engines.

Talusia HR 140 is claimed to have a higher base number (BN) than most of its market counterparts, whilst also offering "the best solution" for preventing corrosion.

Designed for slow speed engines running on high-sulphur fuel oil (HSFO), Lubmarine says Talusia HR 140 has high acid neutralisation capacity, ensuring "excellent cylinder protection".

Its high BN has been created in order to maintain cylinder protection over long periods of high-sulphur residual fuel usage, stopping corrosion resulting from sulphuric acid formation. This, Lubmarine says, prevents cylinder wear and scuffing, and can extend the length of time between engine overhauls.

The second NOL allows for the combined use of Lubmarine's Talusia HR 140 and Talusia LS 25 lubricants in MAN's Automated Cylinder Oil Mixing (ACOM) system.

The MAN ACOM system is an onboard cylinder oil-blending unit designed to simplify the lubrication aspect of fuel switching - allowing vessels to use scrubbers or MAN GI- or LGI-type engines using LNG or fuel mixtures.

Talusia LS 25 has been specially formulated for reliable operations with Emission Control Area (ECA)-compliant, ultra-low-sulphur fuels. According to Lubmarine, it provides "excellent cleanliness and outstanding deposit control for slow speed engines", and thanks to its low-ash content, engines using Talusia LS 25 are said to be protected against deposit formation, which can lead to scuffing issues. It has already been approved by MAN for standalone use.

Commenting on the announcement, Jean-Philippe Roman, Technical Director, said: "For Total Lubmarine and its customers, these approvals are a great recognition of the quality of our products, and show the support of a renowned engine manufacturer. The two products represent a holistic solution to engine lubrication in a multi-fuel era - and reflect our dedication to design the next generation of lubricants to support our customers' compliance strategy."
