Both diesel engines and heat exchanger are using diesel fuel. Main consumption 60-70% is falling on heat exchanger. Consumption level depends on the outside temperature. It is minimal during warm period of the year and increase when outside temperature is dropping. 8. Safety measures The main requirements for the safety of operations are thorough grounding. Static electricity might occur when stream of liquefying agent under pressure contacts with obstacles inside the tank. Any spark is very dangerous at this point. This is why cleaned vessel and all elements of the MegaMacs system including peripheral devices have to be thoroughly grounded. To accomplish this all process hoses are armed with metal sleeves contacted to quick release hose connectors. Therefore strength of the hose insures ground reliability. System equipped with ground control sensors which automatically shut off supply of the cleaning agent to the Robotic Cannon or washing head in case of failed grounding. History of systems operation since 1978 proofs that reliable grounding guaranties safe system operation. No accidence registered since beginning of MegaMacs operations.8.1. Oxygen and hydrocarbons gauges In addition to above, MegaMACS equipped with reliable gas analyzers ULTIMA X. This analyzers monitor and control system. They perform: · Continuous monitoring of oxygen/hydrocarbons ratio inside the tank. · Automatic shut off of main wash pump discontinue transferring of cleaning agent to auxiliary equipment when oxygen/hydrocarbons ratio is out of speck.8.2. Creation of inert atmosphere inside the tank (option) Inert atmosphere inside the tank gives additional safety guaranty. This is achieved by pumping 95% nitrogen from nitrogen generator (500 m 3/hr) to the tank. Generator is built in 20’ container.Usage of nitrogen is regulated by International See Organization (ISO) and applied for the oil see tankers. You can find these regulations in the International script for oil tankers operation (ISGOTT). KMT International, Inc. is offering nitrogen generator as an option. Decision to purchase generator have to be made by the customer based on their respective industry regulations.
