French shipyard DCNS has conducted the factory acceptance test (FAT) of eight converters designed by ECA Group, to be installed on-board Indian Scorpene-class fifth and sixth submarines.

During FAT, the ECA team is said to have assisted DCNS in controlling and validating the functionality of the equipment.

The test has resulted in the acceptance of the whole equipment, which is slated to be incorporated first into the fifth submarine.

“The static converter 60kVA is designed to operate in the demanding environment of a submarine.”

The ECA-built convertors were delivered last month to DCNS, while the convertors for the sixth submarine will be used to support training within the of on-board crew framework.

The static converter 60kVA is designed to operate in the demanding environment of a submarine. It offers a constant 115V/60Hz network out of the submarine battery pack.

The convertor features a front panel, which enables easy access to various parameters, and the whole unit is electrically and thermally protected for both user and equipment safety.

ECA’s compact static converter 5KVA 400HZ produces a steady 115V/400Hz network out of the submarine battery pack.

Its front panel features a touch screen with easy access to various parameters. A series of electrical and thermal protections have been included in the converter to protect both users and the equipment.

With a displacement of 1,550t, the Indian Navy’s 67m-long Scorpene submarines will be equipped with anti-ship missiles and long-range guided torpedoes, along with a modern sensor suite.

The submarines can engage in multiple missions, including anti-surface warfare, anti-submarine warfare, intelligence gathering, operations by Special Forces, and mine laying.

India’s Mazagon Dock is currently building six Scorpene-class submarines, with DCNS being their technology partner.
