I was fortunate to be hired by Shell Vietnam, the first major Western Company to return to Vietnam after the 1975 victory.
In 1989 I made two Vietnam tours as the on-board Shell Representative for the Seismic Survey Vessel RV 'Geco Kappa' surveying offshore Da Nang, our support base.
Location Vietnam - I loved the land and its people, experienced at a turning point in their history. It was also the last traditional Shell 'in-country' permanent staff foreign service set-up - end of an era for both Vietnam & Royal Dutch Shell.
I'll put everything here to do with seismic, hydrographic & oceanographic works that won't fit elsewhere.
For the uninitiated 'the shooting line' is the (preplotted) survey path for the current survey 'run' of the acquisition boat. In the old days they dropped dynamite overboard as an energy source - hence the 'shooting'. Was dangerous then - merely noisy now.
