The purpose of this document is to provide instructions on how to register your scrapedown samples in HTML Offline. Before you begin:

  • HTML Offline Logbook is vessel and asset specific
  • It is recommended that you use your scanner for the registration process
  • Ensure the Mobil Serv workform has been received and saved on desktop
  • Have your scrapedown samples in the 45ml bottle
  • The workform is reusable once received
  • Preferred browser is Chrome/Edge/Firefox



If you have already received your workform, skip to step 5


To request the workform, send email to with one of the following subjects:

  • Html Zip Request: "asset ID"
    • This will send back a zip file
    • Example - Html Zip Request: 650515571
  • Html Request:
    • This will send back a list of available assets associated with users profile

Note the following:

  • Html Zip Request is case-sensitive
  • Asset should not be surrounded by quotes
  • Asset should be a Marine – Engine (Slow Speed)
  • User requesting must be assigned to the vessel

3Within minutes you should receive an email with the workform.  

4Save the attachment (workform) to your desktop
5Click on workform to open

You will now enter general engine operation data thereafter you scan the bottle QR codes to register the fresh oil and the scrapedowns samples per cylinder.


Click on yes or no if the liner / pistons were overhauled since your last submissions.

If no, go to step 15.

(This data influences the measurement interpretation in the engineering report)

8If yes, enter the engine hours at maintenance and answer the following questions about scavenge space cleaning and piston/liner replacement for each cylinder.


The following 7 entries is general data around dates, temperatures, lubricant and fuel in use.

10Click on the Sample date field and select the correct sample date (generally today)


Click on Tested lubricantand pick the correct one from the list


Click on Fuel Typeand1038px pick the correct one from the list. Then enter the Fuel Sulphur % by using the ‘.’ (point) not the ‘,’ (comma), eg: 2.53%


Enter the Fuel Al + Si (ppm) value according to your bunker note


Enter the Outside Humidity % if available (optional field), then the Outside Temperature (Celsius).


The next 5 data points are around the engine operation.

16Enter the Engine Hours at Sampling, usually it is the current engine hours value

17Enter the Engine Power at Sampling (kW). Typically, it is the current engine power value.

18Enter the RPM at Sampling. Typically, it is the current RPM value.

19Enter the Daily Cylinder Oil Consumption (Liter/24h). Typically, it is the current RPM value.


Enter the feed rate value which depends on the type of lubricator you use (HMI, ACC etc.). Calculate the average over all cylinders if you use cylinder specific feed rates.


You have finished the data entry, now you scan your bottles.

Be sure you have the fresh cylinder oil from the day tank or fuel rail as well as the scrapedown samples available.

22aClick on the Fresh Oil Bottle ID field …


…and use your scanner to scan the bottle QR code. Alternatively, you can type in number below the QR code (eg m000052072).

(If the scan does not work properly, ensure you program the scanner to your keyboard language if it is not English - see the instruction that came with your scanner).

23Continue scanning your bottles for all scrapedown samples, ensure you match the cylinder number you marked on your bottle with the cylinder number in this workflow.


When you have finished scanning all your bottles, the envelope will turn blue.  Click on envelope, which will download two files:

  1. JSON (or .dat file)
  2. Email to submit JSON

25Attach the JSON (or .dat file) to the email and click send


  • After the offline logbook is submitted, a confirmation email is sent. The "original payload" link will contain the email and the .dat or .json attachment in it. The "original payload" is NOT the .dat or .json itself.
  • Workform does not validate unique bottle IDs before submission but does validate on being received by Utility Cloud.

  • The QR code field type currently does not support the in-browser camera but does support manual entry of bottle IDs or scanning of bottle ID QR codes with a hand scanner. All other field types validate normally.

  • The save icon validates if the user has incorrectly filled out any fields within the workform.

  • Any email address may be used to submit the workform but the user that requested the workform will be audited as the user that completed it

  • The workform is reusable once received. If a user closes the workform to reopen it, the workform will be empty for a new submission. A user is not able to close a partially completed workform and reopen to finish later.

  • iOS is currently not supported for HTML Offline
