not sure if this is the same company but i worked with a engineer about 2 years ago that sailed on the seismic vessel named black seal ?
also my father sailed on a ship called the Arctic seal (sealfleat) i believe.
I was responsible for positioning of exploration units for Shell Expro in the 80s and we used the Artcic, Baffin and Bering Seals. 3D seismic was coming in and I spent several trips on them all developing the technology.
I worked as a mate on each. The Bengal Seal was a rig supply, the Coral Seal was chartered to Teledyne Exploration, and the Atlantic Seal was chartered to Digicon Geophysical. I will post some pics as soon as I get this site all figured out.
