I had the same reservations the first trip I made with an Intercon system. I feel comfortable enough to sail anywhere in the world with the system now. There have been several failures early on mainly due to lubrication. The lube systems have greatly improved with better lubricants and the grease cycles are controlable from the pilot house. The new Orkot bushings are supposed to be the cat's ass. I never have worked with them. Pre-voyage manually lubing and cycling the pins are paramount. Don't spare the grease, especially on newbuilds. Flushing the load cells and cycling the pressure switches should be done every trip. Also inspect grease and lock hoses when flexing the pins. I think it's Crowley's policy to change out the hoses during annual thrust bearing inspections. During the notch-ups, keep an eye on the oil levels in the intensifyers for the locks.
As in all new-builds, a regiment of re-tightening every electrical connection is part of the daily routine.
