I think there's only one Twin Com on the M register, but can't be sure so there's no guarantee the aircraft in the image above is the incident aircraft, though the registration does almost fit with an earlier post.
It will be interesting to find out if the pilot had an immersion suit or raft - I would have thought an immersion suit to be less likely with a twin than a single, in which case proximity to the standby vessel would be a very significant factor.
