The Civil Aviation Authority (CAA) said safety is its "number one priority" after a poll by the pilots' union Balpa showed more than a half had fallen asleep while in flight.
A CAA spokesman said: "We think the new European flight-time limitation regulations maintain the UK's current high safety levels, and will actually increase safety for UK passengers travelling on some other European airlines.
"The changes will give the CAA far greater access to airline data to help us oversee fatigue risk management. We will shortly begin working with UK airlines over the introduction of the new system."
The Helicopter Safety Steering Group temporarily grounded the Super Puma fleet after the incident, but lifted the ban after concluding that there was no evidence to support it.
The CAA said the review will be undertaken jointly with other safety watchdogs and advised by a panel of independent experts in order to make recommendations aimed at improving the safety of offshore flying.
