## 3 Simulator Exercise Assessment (SEA) Application  
Kongsberg Maritime has developed an application that, after entering the appropriate criteria, performs a detailed, automatic assessment of the trainee activities. This program is the Simulator Exercise Assessment (SEA). The SEA system is an add-on, stand-alone application provided by KM with the entire K-Sim Polaris 7.5 package and is designed to support the assessment process. However, the instructor still plays the main role. It is up to him to prepare the actual exercise scenario and to introduce the evaluation criteria for this simulation. For him, the application is a structured, objective system for tracking multiple parameters and measuring and comparing results. A simplified diagram of SEA work rules is shown in Figure 4.  
The SEA system provides the possibility of assessment at two levels: basic and higher. In both cases, the trainer can choose which values will be monitored during the exercise and then enter the relevant criteria, weighted averages, etc., which will serve as a model of a correctly performed activity. The program automatically compares the data collected during the simulation, considers the factors and criteria, and makes an evaluation. A higher level allows the use of an additional variable, the so-called Environment Links. The classification principle is the same as for the basic assessment. However, it allows a different treatment for the parameter, which was linked, for example, to visibility, approaching a fixed point, etc. In this case, the limits of exercise correctness are dynamically changed. The instructor, after preparing the exercise scenario and analyzing the correctness of the simulation, enters specific criteria and assessment conditions. They can enter up to 50 conditions (limited number of rows). There are 57 different criterion types to choose from [21]. To present the 57 criteria in a more structured way, they have been grouped as follows (data from SEA):  
* Anticollision criteria (_Minimum distance from all ships; distance from ship; distance from CPA; minimum distance to banks; minimum TCPA; relative CPA; relative bearing; and true bearing_);
* Criteria related to the parameters of maintaining the established route or zone (_inside all track sectors; inside all track sector-port side; inside all track sector-stbd side; speed in

* Criteria related to the radar/ARPA use (_radar visible range; radar tracking specific ship; radar tuning; and radar parallel index lines used_);
* Criteria related to the ship's movement and equipment settings (_heading; course over ground; course through water; speed rate; speed over ground; speed through water; rate of turn; pitch; roll; propeller revolution; RPM order (propeller 1); RPM order (propeller 2); thruster order; rudder order; rudder angle; and anchor chain length_);
* Criteria related to the main engine and power supply (_engine power_; start air pressure; and shaft power_);
* Criteria used in the simulation of antipiracy or SAR operations (_radio hail ship; dispatch helo; dispatch rhip; helo source; rhib source; main source; illuminate with main search light; illuminate with helo search light; illuminate with high search light; illuminate with para flare; illuminate with flare gun; warning shots 76 MM gun; warning shots 50 caliber gun;eEngage with 76 MM Gun; and engage with 50 caliber gun_). For all criteria selected for evaluation, specific ranges for their activation should be selected. They can also be linked to each other. In this case, a given criterion will be considered only if one or more of the conditions selected for other criteria are met. This approach allows for a more flexible evaluation of the course of the exercise, which is better adapted to real conditions.
