Weird skeleton statue at The Hague

So, I found this pretty interesting statue, to be honest I don't really know what its purpose is. For me, it reminded me of pirates or something like that, but then again these skeletons are in quite a compromising position...up to you to decide.
What do you think it is? Or maybe you know, I didn't really looked it up, just thought was strange and kinda funny.

If you want to check it out for real, you can find it in The Hague, or as the Dutch call it, Den Haag, according to my phone and google maps here: https://www.google.com/maps/place/52%C2%B004'42.2%22N+4%C2%B018'49.8%22E/@52.0783994,4.3116465,17z/data=!3m1!4b1!4m5!3m4!1s0x0:0x0!8m2!3d52.0783994!4d4.3138352
