This is a case of opposite incentives. If the manufacturer loses the follow-on revenue stream, he or she may not recover the engineering investment for a low-quantity production run (typical of an ROV manufacturer) and thus may go out of business (it happens all too often). If the service com- pany has no other choice for sourcing replacement parts, due to a single-source provider, the ser- vice company has the difficult choice once replacement parts are needed of either accepting whatever terms are provided from the manufacturer or to reverse engineer and manufacture the part (putting the service company into a position where it must then be a manufacturer in addition to its service offerings).
