BEAUFORT SEA

Built in 1971, by Main Iron Works of Houma, Louisiana (hull #258) as the Corsair for Interstate Oil Transportation of Philadelphia, Pennsylvania.

At the time Interstate Oil Transportation operated two fleets. Their Northeast Fleet or "Green Fleet" operated in Philadelphia, Pennsylvania. And their Southern Fleet or "White fleet" which operated out of Tampa, Florida.

However, over the years many changes came to Interstate Oil, when a company called Southern National Resources (also known as SONAT Marine) Purchased Interstate Oil Transportation and SONAT eventually sold out to Maritrans Operating Partners LLP.

In 1998, Maritrans's northeast fleet was thinned and the Corsair was acquired by K-Sea Transportation of East Brunswick, New Jersey. Where she was renamed as the Beaufort Sea.

The tug was later outfitted with a JAK coupler system. She is a twin screw tug rated at 4,300 horsepower.

In 2011, K-Sea Transportation was acquired by the Kirby Corporation of Channelview, Texas, where the tug retained her name.
