Following a detailed six-month study assessing its contract towing requirements, Trailer Bridge Inc. today said it signed separate long-term agreements that match the best marine power units in the market with the company's vessel assets.

“The Heidi class tugs have performed flawlessly for us since March,” said Ed Morley, Trailer Bridge’s vp of marine operations. “We have experienced 100% on time arrivals with the Heidi class tug and Triplestack Box Carrier (TBC) combination.”

Trailer Bridge finalized a long-term agreement with Moran Towing Corp. to exclusively use Moran's Heidi class 4,350-horsepower tugs to pull all four of the TBC's currently deployed by Trailer Bridge. The decision followed results produced through Trailer Bridge’s use of two Heidi class tugs.

The Company's TBC vessels are used for weekly services between Jacksonville, FL and San Juan, PR, and Newark, NJ and San Juan.

Trailer Bridge's TBC vessels are the first vessels built for the U.S./Puerto Rico trade in more than 15 years. The TBCs are specifically designed for efficient ocean and cargo operations and are the first vessels in the world to exclusively carry 53-foot high cube containers.

Trailer Bridge also announced that it has finalized a long-term agreement with Crowley Marine Services, who will provide two Invader class 7,200 horsepower tugs to pull Trailer Bridge's two Triple Deck Roll On/Roll Off vessels between Jacksonville and San Juan.
