Also most ocean world's have no significant land mass at all on the surface, maybe a few tiny archipegelos if lucky but that would be about it. With the almost infinite numbers of resources that the imperium has, forge worlds could probably be able to produce sea-base dships from the manufactorums.

Also to add one more thing the Adeptus Munitorum would probably not have a problem sending in a few ship to fight on a Planet that is covered entirely in water, insted of sending a fleet of vast starship's, regiment's and rear echelon force's to support them.
