**3.6 The proposed system: Complementary solution**

For completeness of the system-level analysis, we suggest having a complete system composed of four subsystems as shown in **Figure 8**:

	- a. The detection algorithms proposed in Section 3.2 are applied. If the probability of detection exceeds the threshold set by the persons in charge, then there is a need to prepare to start the contingency plan.
	- b. The estimation algorithms proposed in Section 3.3 are applied. Thickness values greater than 1 mm indicate the need for quick intervention because the oil slick will persist for a long period of time.
	- c. The classification algorithm in Section 3.4 is applied to have an indication about the oil type.
