Alan Picken,

James Fisher Marine Services

SOS recently supported James Fisher Marine Services with a seabed sampling scope in the River Dee estuary area, they provided one of their Commercial RIBs along with the skipper to transport personnel and equipment out to the location for the sampling works.  Their service was very professional and punctual and competitively priced.  We look forward to working together with CMSS on future projects.

Regarding engine installation

Thank you for the lovely neat job you made on the installation of the outboard.  I didn't have a chance to take her out yet but having had a look at the install I was really pleased.
