Russian to English Tech/Engineering Engineering: Industrial

This acronym appears in a document about a shipyard - this is the part where the shipyard's business activities are listed. I've got a hunch that it's to do with spare parts, but I just cannot seem to find the full extrapolated version of the acronym anywhere!

Here's the context:

производство, ремонт, модернизация, переоборудование, гарантийное обслуживание и гарантийный надзор надводных военных кораблей и военновспомогательных судов, производство ЗИМА к ним,

I'd be very grateful for a wee bit of help on this. Thanks in advance!
