EST-Floattech receives DNV-GL Type Approval for Energy Storage Systems

Press Release

EST-Floattech announced today that it has received the DNV-GL type approval certificate for its Green Orca® High Energy batteries. This system is unique in that it is intrinsically safe, with a fully passive protection system based on EST-Floattech’s ‘Safe by Design’ philosophy.

The importance of the DNV-GL Type Approval
DNV-GL is one of the most important classification societies when it comes to inspecting maritime battery systems. With the certification, insurers know that ships built with the Green Orca® High Energy batteries meet the strict requirements stipulated by DNV-GL. As its name suggests, Type Approval certification is a procedure for approving certain types of products that can be installed aboard vessels.

Type tests conducted
In order to identify the risk potential in the system, tests are conducted in accordance with e.g. IEC62619 and regulations by DNV-GL. These tests involve the cell, battery and battery system levels, and include a thermal test, external short circuit test and forced discharge test, but also environmental tests, such as vibration, dry & damp heat, and EMC.

The “Safe by Design” Philosophy and Propagation Protection
One of the most important tests is the internal thermal event test, also known as the ‘propagation test’. EST-Floattech is unique in its passive safety system, which guarantees safety on board.
