Portosalvo is an Italian company who have owned one or two UT 755s for a number of years. The ships have always been managed by Gulf Offshore UK, and this continues at the time of writing (April 2010). The specifications of the vessels are included in the Gulf pages as well as here.

In a degree of confusion it appears that the company commissioned an AKER PSV 09CD at some point and one of the builders lists  shows one as an option, but if the ship was built it does not show up on the Gulf Offshore list. 21/2/12

Portosalvo do not have their own site but Gulf Uk manage their ships and these two featured here seem to be the lot.

At the 2014 review it appears that the company have gained one ship which is also managed by Gulf. It is included here as well as on the Gulf site.
