Shell launches high BN cylinder lubricant
Shell Marine has developed a new lubricant to protect modern ultra-efficient diesel engines against cold corrosion while still optimising cylinder oil feed rates, across the entire range of vessel operating conditions.
The new Shell Alexia 140 has now successfully completed over six months of shipboard trials with a Shell Marine customer.
It is an ultra-high BN oil with a BN of 140 and is targeted for use on its own or as part of an onboard lubricant blending or mixing system.
Jan Toschka, general manager of Shell Marine, explained: “We are responding rapidly to the changing needs of the industry, helping our customers to cope with their full range of operating conditions.”
He said: “This latest development underpins our commitment to the industry and its future. We have our own in house testing capability and extensive field experience, coupled with the monitoring, analysis and advisory services to respond to the market with proven and comprehensive solutions.”
MAN Diesel and Turbo (MDT) told this year’s CIMAC in Helsinki that it had been trailing ACOM, the two-stroke marine engine major’s pilot scheme to establish best practice in matching lubricant BN to fuel sulphur content whilst minimising lubricant feed rates.
A Shell Marine customer was selected for the first batch of trials.
“Major OEMs now recommend cylinder drain oil analysis as a way for ship owners to optimise feed rates as it allows them to strike the right balance between corrosion protection and minimised oil consumption,” added Mr Toschka.
He concluded: “Shell Marine is focusing on solutions that are operationally straightforward. These include cylinder oil condition monitoring and drain oil analysis, the software and advisory services that help to interpret and implement OEM requirements, and assisting ship operators to develop crew skills as well as knowledge.” “In all areas, our objective is to work with the customer to deliver the most reliable solution.”
