Dearsan (NTPB contractor):
Dearsan has presented some coast-guard vessels, opv and corvette designs in IDEF 19. Enlarged versions fo NTPB suits well for this, as well as 90 meters corvette offered for Turkmenistan also possess some potential. 2 of the corvettes presented below can be converted to OPV when needed. However, in my opinion when we need an OPV of +90m, Ada class (as in TCG Ufuk example) can be easily converted for such needs with light arms, Aselsan STOP-Muhafız RWS.
Modified NTPB with landing deck and 2xRWS for Coast Guard.

Final notes:
Unlike the cutting edge Fast Attack Craft requested by Navy (High speed-heavily armed-sleek) , an OPV is much easier to design and build with the current experience of multiple shipyards and design offices. We will have variety of options once Navy has published such a request. It will be a nice competition. Some of these designs have competed in tenders of foreign navies, they may possess foreign systems for convenience.
