A buffer storage tank (21) at a semi-submersible production platform having at least two underwater floaters (12, 13) is mountable between the latter and communicates with the deck structure (10) of the platform by means of a shaft (23). The shaft encloses, just above the tank a pump room (24), and above the latter a separating chamber (25) which communicates with the surrounding sea below, as well as above the operational water line (OWL). <IMAGE> |
