“After getting certified, BSP’s plate mill has despatched around 1,938 tonnes of IRS grade-B plates out of the ordered quantity of 1,995 Tonnes by HSL between April and December 2019,” a SAIL
spokesperson said. The IRS grade plates rolled out in the plant’s plate mill would be used for manufacturing of Diving Support Vessels used for search, rescue and repair of undersea submarines, and other structures.
The spokesperson said the requirement of plates was substantial considering the orders placed by Indian Navy on HSL. The company would be getting more orders for the special grade, he added.
BSP had been exporting ship-building grade plates and producing warship grade plates DMR 249 A for Indian Navy, which had certification from Lloyds Register Asia (LRA), American Bureau of Shipping (ABS) and DetNorskeVeritas (DNV). The DMR 249 A grade plates that BSP continues to produce have been used to manufacture hull of Indian Navy’s aircraft carrier INS Vikrant and several other warships.
