6. Some of the Key Refit Activities across various Disciplines / Class of Ships & Submarine undertaken by YMSPL are shown in Pictures Below.

We make marine systems like Pontoons, Caisson gate, Barges etc and work on oil & gas rigs/ platforms of ONGC/ SCI etc.

Presently we are making 3 - 280 Tons berting Pontoons & 1 - 1350 Tons Caisson Gate for DGNP/ ENC.

1. We have Collaborated with some of the best companies in the world to get customized & cost effective solutions locally. Major emphasis is on Reliability/ Maintainability/ Life Cycle cost of the equipment. We provide 360 Degree services in respect of these equipment starting from Supply/ Installation/ STW/ T&T/ Trials/ After Sales Support and Services through Rate Contract/ AMC/ Major Overhauls.

2. Following major equipment orders are in various stages of supply:

• Supply of RAS/ FAS Equipment for SVL(GRSE), DSV(HSL), ASW Shallow Water Craft (GRSE, CSL), 1135.6 Fregat (GSL), Deepak (L&T)
• Shakti : Spares for RO Plant.
• FAPMO Spares

3. Details of OEM's with their products are depicted in "Products Category in Detail"

1.We have developed/ are developing user specific products for defence forces. One of the major product designed and under production/ supply is RESS system which is expected to prove as major force multiplier for our ships/ submarines at sea. The system involves design of high latency data network and is based on Patented Technology.

2.The RESS System aims to provide maintenance support for Embedded Systems in all modern systems of ships and submarine at sea without the need for them to return to harbour or yard for defecation. This is done using the existing satellite communication network of the Indian Navy through which specialised setup on the ships or submarines is able to communicate with complementary setup at SEGs or any other centre in yard for trials/ tuning/ defectation for direct and instant online help.

3. We are currently manufacturing 10 RESS Systems, which are planned to be delivered from Nov 22 to Jan 23.
