Wasn't OEI, chip indication without secondary so just a roll back to idle. Can be rolled back up if required. Everything offshore these days is satellite tracked, with 30 sec frequency if you flip the "concerned" switch. Good call by the crew of the other aircraft, if they had loitered around in the dark trying to stay visual with the slower aircraft to only provide a location that is already well known, then they'd be in my office the next day.
Different strokes... this is a profession, not a support group.
