Icon Research released a brand new version 6 software in 2014.

Since its first release in 1994, the Doctor Analysis Software’s comprehensive analysis features combined with ease-of-use has made it first choice for thousands of diesel engine operators. A programme of ongoing development has ensured that the software continues to lead the field.

The software can be downloaded or provided on a USB key along with a “Step-by-Step” guide to enable the operator to familiarise himself with the application as quickly as possible. The intuitive nature of the application makes the learning process even easier. The software is supplied with a suite of sample engine measurements to experiment with. There is no restriction on the number of computers that the software can be used on, so engine measurements can be freely passed between operators, analysts and managers.


Indicator Chart in detail

First of all, a library is created for the vessel or power plant. Settings such as engine geometry and firing order are entered here. An unlimited number of configurations can be stored for later use. The configuration storage is flexible and allows multiple ships or plants each to have multiple engines in the same library, or alternatively any number of separate libraries can be used. A setup service is available with all new systems from Icon, giving users a flying start and including a check on initial results.

Measurements are downloaded via the computer’s USB interface port and stored in the Doctor library. Sections of the library known as logbooks can be imported or exported easily to colleagues anywhere in the world for further analysis or comparative work. These logbooks are easily combined with a master library in the head office, using click and drag operations.

The basic traces that can be observed are Pressure-Angle, Pressure-Volume and Derivative (Rate of Pressure Rise). From these traces, various parameters are derived such as power, MIP, rate of pressure rise, and many others. In addition, user-defined variables can be entered, such as exhaust gas temperature. These values can be shown in tabular form for easy comparison. Variations are automatically calculated, such as variation in power between cylinders.

Cursor readouts are available on single or multiple traces. When more than one trace is displayed, the cursor will show the data on all curves at that position together with the maximum deviation from lowest to highest.

Multiple engine selections can be made, and you can look at similar engines from different vessels all at the same time. This is an invaluable tool for the management of fleets of vessels. 

Now propeller curve analysis and shop and sea trial comparisons are included in the software.

Hardcopy printouts are available at the touch of a button.  You can download the Doctor Analysis Software by registering here. A demo version is available for evaluation. A license can be purchased to allow activation of the software.

Version 6 software is available in three variants:

  • Standard 6
  • Diagnostic 6
  • Shop/Sea Trial 6

The table below details the features available in each of the three variants.

Data Archiving and Recall

Data can be archived for historical purposes or for transferring engine measurements between interested parties. Measurements selected by engine and by date can be compressed into a single file for onward transmission (via email, for example) and subsequent restoring. Each archive is a database in its own right and can be opened straight from an Email message by double clicking (provided you have Doctor software of course).
