NO.	Required Data	Data Provided by EXA	Details of the Procedures
①	○	-	Please provide the table for Partly Filled Untrimmed Grain in CSV format. And if the existing Trimmed Grain Table including the Trimmed Full and Untrimmed Full are also changed, provide its new table in CSV.
②	○	-	Please provide the original Grain Loading Booklet. If you need not ③ and ④ service, please provide the new Grain Loading Booklet including Conditions of new Grain Code.
③	＊	-	Please give us instructions to create conditions using Partly Filled Untrimmed Grain Loading. ※If more than 40 condition cases are required, the additional cost may be required.
④	-	○	We will create grain loading conditions instructed and give them to you as pdf files. (Only the Trim calculation results and Stability calculation results are used.)
⑤	＊	-	You submit the new grain loading booklet or addendum including the above new cases for the class approval. (Only the Trim calculation results and Stability calculation results are used.)
⑥	＊	-	After you have the new grain loading booklet approved, we can start to update the grain loading functions of your loading computer.

1700 results have already been achieved after "LOADCAL series" of our company is put on the market, and we get the favorable comment from a lot of users.

You can use it at once without special operation guidance after introducing the system because the calculation procedure is displayed in the display by the menu form and it becomes an interactive mode to be able to check the relation of I/O at any time. Moreover, consideration to the false operation is also thorough.
In addition, the extendibility with other special and general-purpose software is considered enough.

The input of each data and the calculation results can be displayed by the multiwindow form, and because whenever the input or change of weight for each division is done, draft, trim, stability and longitudinal strength is calculated, and the result is displayed, the best loading plan can be got promptly.

Because latest various standards and rules of the flag state and the shipping classification society are included, a decision to pass or fail for considering loading condition can be gained promptly. This system is compliant with IACS URL5 (Unified Requirement for "Onboard Computers for Stability Calculations") and 2008 IS Code.

Because the calculation results are printed in the report form, it is possible to use it as it is as a submitting document. Moreover, it is also possible to send it to the office on land at the same time by the communication function between the ship and land.

Because the data management of the save and correction etc. is easy, user can manage the whole possessed ships in the office on land simultaneously by the communication function between the ship and land.

LOADCAL has abundant options so it can satisfy various demands of the user.

The protection function is installed so that ship's lines information never leak outside.
