OPV tasks range from long routines of surveillance and inspection to enforcement by interdiction, arrest and if need be, low-intensity combat, particularly where armed and lawless groups (e.g. piracy or terrorism) pose a threat to maritime security and the peaceful passage of trade. At the same time the OPV must always be capable of search and rescue and maritime disaster response. These tasks require ships that are designed for sustained blue-water operations and that are robust, reliable, simple to operate and easy to maintain. Above all the OPV must be economical to acquire and operate. thyssenkrupp Marine Systems has just such a vessel: the MEKO® OPV.
