Not at all, someone pointed out that putting the helideck on the front of the vessel was a bad idea, I countered that with the fact that the vast majority, if not all vessels working in the offshore industry have helidecks in front, the photo was an example of what most of them look like.
More like this, there are three of these vessels under construction at the moment, it's called Project 21900M, I know it fairly well, I sold shipyard the lights that will be used onboard. Either way the flight deck is forward of the bridge and it's very common.
The Russians carry helicopters on many of their icebreakers and as far as I know none of them have hangars. You also see tuna boats with embarked helicopters but no hangar.
We wont operate out helicopters like that, because they have to last us 20 - 30 years. You can't store a seasprite in the rain and salt spray. Unlike civilian helicopters the seasprite is extremely maintenance intensive, requiring daily, 7 day, 14 day, 28 day and 56 day servicing, that need a hangar.
Not to mention the SHOLs on a design like that would be so restrictive we'd never actually be able to fly.
