NTT would like to extend its vessels’ oil-drain interval without compromising on product quality and services, and, importantly, to improve the efficiency of its vessels through fewer breakdowns.
The front-line technical support at Shell Marine’s distributor, PT Cahaya Samoedera Bersaudara (CSB), with support and guidance from the Shell Marine’s technical team, proposed that PT NTT ran a trial using Shell Rimula R4 X 15W-40 engine oil. Through the oil’s triple action technology and superior quality, PT CSB and Shell Marine were confident that the oil-drain interval could be extended, thus meeting PT NTT’s objectives.
Tests conducted through the used oil analysis programme and expert diagnosis by the Shell engineer and the local laboratory showed that the oil-drain interval has been extended from 700 to 1,000 hours; 42%. The vessels also operated efficiently without any issues during the trial and after the switchover to Shell Rimula R4 X 15W-40.
PT NTT has extended the oil-drain interval its vessels and is thus operating a more effective fleet and, importantly, achieving its objective of reducing lubrication costs. PT NTT has reported potential annual savings of about US$20,0001 per vessel through either an extended oil-drain interval or lower oil consumption.

These calculations may vary from site to site and from time to time, depending on, for example, the application, the operating conditions, the current products being used, the condition of the equipment and the maintenance practices.
