Marine Grounding System
SEK-3
Marine Grounding System
In the process of transferring petroleum products and inflammable liquids to and from oil and chemical tankers, there exists a potential risk of creating a hazardous environment. This risk arises due to the variance in potential between the tanker and the pier, often attributed to galvanic processes. Consequently, the connection points of loading hoses, loading arms, and other conductive equipment can generate sparks, which may lead to ignition within the surrounding atmosphere.
To mitigate the potential hazards associated with stored energy in inductances, it is imperative to prioritize the implementation of a robust equipotential bonding system. As an additional safety measure, the SEK-3 solution ensures secure potential equalization between the ship and the shore, conforming to globally recognized industrial standards such as ISGOTT / ISGINTT, thereby achieving the highest level of safety.
Key Features
