I totally agree that single pilot night offshore in a single engine helicopter is bloody dangerous.
BUT pilots who need to make a living can be forced into it by Regulatory Authorities who care more about the commercial aspects of an operation than they do about it's safety. Curious that the two countries that are the worst offenders in this way apply totally different standards to Fixed Wing and Helicopter Public Transport Operations; and this is reflected in the relative pay and conditions of the two industries there.
You can't blame the operator; it's the duty and responsibility of the Regulator to ensure a Safe and Efficient industry, not to pander to powerful commercial and political interests. IT'S ALL DOWN TO THE REGULATOR.
Governments don't normally care unless somebody embarrasses them in public with a campaign; and this is a cultural thing in the country in which you live, people may or may not approve. You'll be accused of trying to create more jobs for pilots and trying to destroy the economics of the industry. We went through all this in the North Sea a long time ago, and frequently again since; but safety is a high-profile item in Europe. Many countries where commercial interests rule don't share that view when it comes to helicopter operations and Regulation is correspondingly slack.
