[LOADCAL] Ship's Loading Computer & Stability Computer

LOADCAL always satisfies the latest IMO and Class rule and supports safety of a ship promptly and easily

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.

Feature of System

Operability and Expansibility

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.

Satisfy the latest demands of the flag state and the shipping classification society

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.

Business support

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.

Data management

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.

Abundant options

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

Protection of ship's lines information

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