[LOTR] Did Sauron expect to die when invading Valinor?

Did Sauron believe the Numenorean invasion of Valinor would succeed or did he expect all the Numenoreans to get killed by people in Valinor? I can see either way being his expectation since he got his main rivals to fight each other. If he expected Numenor to lose, what was his exit strategy, especially to ensure the Ring didn't get lost? Did he figure out exactly how to use his spirit to carry the One Ring back to Mordor in preparation before the invasion? Was he expecting to lose his shape shifting ability when planning the invasion or was it unexpected? Did he feel content with trading his shape shifting for  Numenor's destruction or did he regret his decision?

Sauron himself was not part of the invasion force. He was sitting back in Numenor to watch the fireworks, fully expecting the Valar to kill the Numenorean attackers and perhaps also to inflict some sort of reprisal on Numenor itself. The direct intervention of Eru, resulting in the complete destruction of the island of Numenor as part of a process that reshaped the world itself, was beyond anything Sauron had expected or was prepared to deal with. The destruction of his physical form was therefore an unanticipated setback, but to one with Sauron's abilities not a fatal loss.
