I suppose it could be assumed that the shells detonate within a traget or before any significant penetration of the hull can take place.

Nope, the explosion of the round itself may be enough to puncture a ship's hull.

As said before, a Space marine's suit is voidproof, so he doesn't really care if the atmosphere suddenly goes rushing out of the ship.

To the OP, check the Gaunt's Ghosts books - I remember Abnett specifically describing the shotgun's round as being filled with metal shavings and other pieces of shrapnel, so it would shred people and not the ship's hull.

I am building up a Planetary Defence Force of Vostroyans and thought it would be cool to have a squad or two dedicated to Battle Zone Mortalis with the idea of them being stationed in a space station/dock in orbit.

Now in most of the novels it says that the Navy security dudes use a form of shotgun to stop holes being punched into equipment and life support systems etc. However it then dawned on me that Space Marines often fight on ship and don't seem to give a crap about their bolters shooting off everywhere. Do they use a different type of ammo for boarding/repelling boarders?

Or is the idea of shotguns in space old news now?

As a note PDF forces would not garrison Navy assets, due to the seperation of power the Navy would use their own forces.

Sure, but Traitor Astartes boarding parties tend to go for the "critical" parts of a ship--and they have no qualms with using heavy explosive/penetrative weapons like Meltaguns.

When the Naval Security teams have to respond to those threats--they're pretty much boned, as they'll have to use weapons heavy enough to crack open and kill the powered armour which will probably do damage to the hull.

Again, what small arms round would be powerful enough to puncture a hull designed for ship-to-ship combat?

Meltaguns.
Plasmaguns.
Meltabombs.

To kill a rampaging Astartes inside of a ship, you're going to have to bust out explosive weapons.
Breaking out explosive weapons in the middle of a space battle, when other people are shooting at you and causing structural damage and your crew are not wearing armored voidsuits you are asking for an issue.
