Callan Marine is progressing well down in the southern tip of Texas. Callan is now more than 70% complete with dredging 7 million cubic yards to deepen 8 miles of the Brazos Island Harbor Ship Channel in Brownsville, Texas. Over the past 13 months, this project has hosted several dredges including the 18″ General Marshall, the 28″ General Bradley, and the 32″ General MacArthur. The project has been supported by a booster barge, our multi-purpose & specialized Multicat Sgt Harrell, and numerous other tugboats, supply barges, crane barges, survey boats, crew boats.
The Callan team has been collaborating well with the USACE, and striving to be problem solvers. Some project challenges have included: the material composition, which is some of the most difficult to pump; the scattering of metal debris from local shipbreaking facilities; and, the narrow design of the ship channel (approximately one quarter as wide as the Houston Ship Channel). But, with the aid of Callan’s Marine Construction Division to target and remove debris and the diverse, powerful fleet of our Dredging Division, the project continues.
While the team’s focus is strongly aimed at the goals and tasks ahead, every now and then some entertainment from neighboring SpaceX breaks the monotony of a desolate landscape with a rocket launch, or the US border security team comes racing through the dredged material placement area followed by reconnaissance blimps overhead.
