A trio of top tanker owners teamed up in Houston, Texas, for a joint festive cocktail party, raising more than $36,000 for medical charity Mercy Ships.

Stena Bulk, AET and Teekay sponsored the event to raise awareness of Mercy Ships in the US. The charity operates the world’s largest civilian hospital vessel, the 16,572-gt Africa Mercy (built 1980).

About 300 people attended the event from charterers, agents, shipbrokers and tugboat companies.
