PT SPIL - Reduces cylinder oil feed rate using Shell lubemonitor
Reduced oil feed rate saves the company about US$17,300 a year per vessel1
Company: PT Salam Pacific Indonesia Line
Application: Main engines
Vessel: Container ship
Key Edge: Shell Lube Monitor, Shell Alexia 50
Based in Surabaya, Indonesia, interisland freight forwarding company, PT Salam Pacific Indonesia Line (PT SPIL), has a strong fleet of 73 vessels and 28 offices located across the Indonesian archipelago. PT SPIL is renowned for being the shipping pioneer of East Indonesia. In 1996, the growing need for broader coverage and the demand for more-reliable interisland shipments led PT SPIL to improve its service through handling more break-bulk cargo and using more-efficient means of transport utilising unitised containers. Supported by a Shell team, the company continues to improve its network to provide highquality services for its customers. As part of this process, PT SPIL wanted to reduce and optimise its vessels’ lubricant consumption and to cut its lubrication costs without compromising on engine protection.
With support from Shell Marine, PT Cakrawala Maju Mapan (PT CMM), the Shell Marine distributor, suggested a trial using one of Shell Marine’s technical services programmes, Shell LubeMonitor, in the main engines of the containership MV SPIL HANA to see if there were any opportunities to optimise the cylinder oil feed rate. As the vessel is using Shell Alexia 50 cylinder oil, PT CMM believed that such a programme could result in a reduction in feed rate that would help to reduce and optimise cylinder oil consumption.
To run the trial, PT CMM needed to educate and train the vessel’s crew on sampling procedures, piston underside inspection and collecting the necessary data. They also had to persuade them that all the data and the piston underside inspections could be used to help reduce the feed rate safely and, thus, optimise lubricant consumption. PT CMM proposed using the Shell Lube Monitor service to monitor engine wear through measuring the iron in the cylinder oil in the MV SPIL HANA using a Shell Onboard Test Solutions device.
The feed rate was initially reduced from 180 to 160 l/d: a reduction of 20 l/d or 3,600 l/y. After a period of satisfactory results at 160 l/d, the feed rate was reduced further to 120 l/d: a total reduction of 60 l/d or 10,800 l/y.
With the feed rate reduction programme, PT SPIL has reduced its lubricant consumption and increased its efficiency for a more-effective fleet. It reports savings on lubrication costs of about US $17,300 a year for one vessel.1 Further savings may be possible, as the programme is ongoing and still striving to achieve the optimal feed rate.
Challenge
Interisland freight forwarder PT SPIL wanted to reduce and optimise its vessels’ lubricant consumption and cut its lubrication costs without compromising on engine protection.
Solution
With support from Shell Marine, PT CMM, the Shell Marine distributor, suggested a trial using Shell LubeMonitor in a reduced feed rate programme on the MV SPIL HANA.
Outcome
The trial showed that the feed rate could be successfully reduced from 180 to 120 l/d: a reduction of 60 l/d or 10,800 l/y.
Value
With the feed rate reduction programme, PT SPIL has successfully reduced its lubricant consumption. It reports savings on lubrication costs of about US $17,300 a year for one vessel.1

Shell’s net carbon intensity and net-zero emissions target
In this content we may refer to Shell’s “net carbon intensity” (NCI), which includes Shell’s carbon emissions from the production of our energy products, our suppliers’ carbon emissions in supplying energy for that production and our customers’ carbon emissions associated with their use of the energy products we sell. Shell’s NCI also includes the emissions associated with the production and use of energy products produced by others which Shell purchases for resale. Shell only controls its own emissions. The use of the terms Shell’s “net carbon intensity” or NCI is for convenience only and not intended to suggest these emissions are those of Shell plc or its subsidiaries.
Shell’s operating plan and outlook are forecasted for a three-year period and ten-year period, respectively, and are updated every year. They reflect the current economic environment and what we can reasonably expect to see over the next three and ten years. Accordingly, the outlook reflects our combined Scope 1 and 2 target, NCI target and our oil products ambition over the next ten years. However, Shell’s operating plan and outlook cannot reflect our 2050 net-zero emissions target, as this target is outside our planning period. Such future operating plans and outlooks could include changes to our portfolio, efficiency improvements and the use of carbon capture and storage and carbon credits. In the future, as society moves towards net-zero emissions, we expect Shell’s operating plans and outlooks to reflect this movement. However, if society is not net zero in 2050, as of today, there would be significant risk that Shell may not meet this target.
The information provided above regarding Shell’s NCI and net zero emissions target are not intended, nor should they be construed as introducing, suggesting or making any claim, target or representation thereof other than what is included in the content.
Forward-Looking non-GAAP measures
This content may contain certain forward-looking non-GAAP measures such as free cash flow and underlying operating expenses. We are unable to provide a reconciliation of these forward-looking non-GAAP measures to the most comparable GAAP financial measures because certain information needed to reconcile those non-GAAP measures to the most comparable GAAP financial measures is dependent on future events some of which are outside the control of Shell, such as oil and gas prices, interest rates and exchange rates. Moreover, estimating such GAAP measures with the required precision necessary to provide a meaningful reconciliation is extremely difficult and could not be accomplished without unreasonable effort. Non-GAAP measures in respect of future periods which cannot be reconciled to the most comparable GAAP financial measure are calculated in a manner which is consistent with the accounting policies applied in Shell plc’s consolidated financial statements. These forward-looking non-GAAP measures are provided to assist readers in understanding management’s use and expectations of such measures and may not be appropriate for other purposes.
