For 60 years, machines and tools clanged though the cavernous Goltens Marine machine shop in Red Hook, Brooklyn. Mechanics rebuilt giant engines and drive systems of ships and tankers stranded throughout the world. On July 3, 2014, Goltens closed. The building was sold to a New York City real estate developer—a casualty of the neighborhood’s changing demographics and corporate consolidation. These photos capture Goltens’ final days, and the employees who built their careers (for some, as many as 40 years) in its greasy workshops and (now missing) towering machines.
