Ship management company reduces oil feed rate by 25% using Shell LubeMonitor service
Company: Oskar Wehr KG (GmbH & Co.)
Application: Main engines
Vessel: Bulk carriers and containerships
Key Edge: Shell LubeMonitor
Oskar Wehr KG (GmbH & Co.) of Hamburg, Germany, is part of the Wehr Group and currently provides commercial and technical management services to 25 vessels, including 12 containerships ranging in size from 1,730 to 5,100 TEU, and 13 bulk carriers ranging in size from 55.000 to 176.000 dwt.
This included using the onboard Shell Onboard Alert iron wear measurement device; monitoring the total base number (TBN) with Shell Onboard Plus kit; and using the Shell Rapid Lubricants Analysis oil and equipment condition monitoring service with the support and guidance from Shell lubrication experts. Oskar Wehr immediately equipped the whole fleet with facilities to take both the onboard measurements.
Engine monitoring started in January 2015 on the container vessel Wehr Hong Kong, which is powered by a MAN B&W 9 K90 MC-C engine, when the feed rate was adjusted to 0.8 g/kWh using Shell Alexia 50 (BN70) and Shell Alexia S4 (BN60) cylinder oil. In October 2015 after comprehensive monitoring of lubricant performance, the vessel was able to reduce the oil feed rate by 25% to 0.6 g/kWh.
In addition, some of the vessels’ engines were inspected. Their liners and pistons remained in good condition.
