"We have to bring in another striker and we’re working on it now to buy one, or loan one, or both," the Hammers chief told the Sports Bar.
"You can never have enough strikers and really with Andy gone we haven’t got enough."
Last season Carroll did not make his first appearance for Hammers until January and Sullivan confessed the club had erred in investing everything in the striker.
"It was desperate last year... We probably made a mistake by putting all our eggs in one basket," the co-owner added.
"Had we known what we know now we wouldn't have signed the player. But it's easy to be wise after the event. We were assured by our physio - who has since left the club - that the player would be available for the start of the season.
"He wasn't available until January or February. A mistake was made and we were given the wrong information. We based our decision and our purchase of the player on what the medical department told us.
"We've changed everything in that department as a result of that. At the same time on his day he is a devastating and fantastic player, we've just got to get him back to his best.
"But at the same time we can't start the season with the strikeforce we've got. I don't think it's good enough, there's not enough height in it and if we get another injury, in terms of quantity, it's insufficient, so we have to sign at least one more player."
