Jackson Marine was owned by the Halliburton Corporation. They owned a total of ninety boats mostly offshore tugs, a few supply boats and some chemical transport and some well stimulation boats. Jackson Marine would later merge with Zapata Marine, and Gulf Fleet. When the three merged the company became the largest shipping company in the world with a total of four hundred fifteen boats. Tidewater at that time had about two hundred seventy five boats.
In the fall of 1986, Seahorse was merged into Zapata Gulf Marine adding an additional ninety vessels to the fleet. Seahorse was founded by the Arthur Levey family as Arthur Levey Boat Company after WWII. Later it was purchased by Petrolane Natural Gas and renamed Seahorse Marine. In 1985, Petrolane was bought out by Texas Eastern a larger natural gas company. Then in the fall of 1986, Texas Eastern traded the company to Zapata for an exchange of stock.
