Sound Tanker specializes in arranging for the shipment of large -- very large -- quantities of chemicals, oils, and other liquids from port to port almost anyplace on earth. Operating out of second-floor offices overlooking the water near Calf Pasture Beach, Sound Tanker's brokers are experts on such arcane subjects as international maritime regulations, port expenses and restrictions, bills of lading, letters of intent, tank cleaning procedures, and real-time market analysis of supply and demand. The office is open in during business hours, but the brokers are available 24/7, providing access to clients in any time zone.
