Most twin engine Airliners are now approved for these flights, as long as the Operator is also approved, sometimes operating up to 3 hours away from a suitable Airport.
When I did the B767 course at Boeing back in 1980 prior to the introduction of the B767 to Australia, when this ETOPS was very new, our instructor told us the "official" Boeing line, that the odds of one of these engines failing was very high, and in the event of an engine failure, the odds of the engine on the other side failing were massively higher, like millions to one.

However he then told us his personal theory on the odds...... 8O
He said if you are over the middle of the Pacific and one engine fails, remember that the only other engine you have, was made by exactly the same manufacturer, possibly even consecutive serial numbers, probably assembled by exactly the same people as the other engine using the same parts and components.

He said he thought the odds of the other engine failing soon were not good at all. 8O
