3. ET - ENVIRONMENTAL TECHNOLOGIES OPK - Oil Spill Protection Kit  Spills can happen in the open sea, close to shores, or in lakes, streams and rivers.  How the spill is cleaned up depends on where it happened.  One cc. of petrochemicals can contaminate 106 cc of water, so oil spills require an immediate response.  When oil enters the ocean it quickly begins to change and disperse.  It is a global environmental problem, specially to countries with coastline like Portugal.

4. ET - ENVIRONMENTAL TECHNOLOGIES The OPK, consists in four flutuable boxes with chemical agent and a sensor based monitoring system.  Activation System Unit - Main Control Box, 2 inclinometer sensors, 6 impact sensors  Floating Device - Four flutuable containers with chemical agent (FOA)  FOA - floating oil agglomerating agent The four containers will be applied around the main vessel as seen in diagram 1. PRODUCT PRESENTATION

5. ET - ENVIRONMENTAL TECHNOLOGIES other technologies In situ Burning collect and burning the oil. Mechanical containment or recovery. booms, barriers, and skimmers, as well as natural and synthetic sorbent materials. booms and fences are often of little use in the open seas. They cannot contain a spill when there are big waves or strong currents. Chemical and biological methods Dispersants and gelling agents are most useful in helping to keep oil from reaching shorelines and other sensitive habitats. These methods have side effects for the environment and are usually toxic.

6. The Activation System Unit has two operation modes : ET - ENVIRONMENTAL TECHNOLOGIES Operation Procedure ( see diagram 1) manually- in case of automated operation failure or if some spill ocurrs during charges and discharges operation. automatically - by a inclinometer based sensor or impact sensor, with time delay mechanism for optional aborting procedure
