Tallvine Partners has acquired Donjon Marine Co.
Independent investment advisor Tallvine Partners has acquired Donjon Marine Co., a critical US marine infrastructure platform, marking the creation of Tallvine’s third platform and the establishment of its North American marine infrastructure strategy.
Donjon Marine was founded in 1964 by J. Arnold Witte and specialises in marine infrastructure with a comprehensive suite of essential solutions for the operation and maintenance of North America’s waterways, coastal regions, and harbour infrastructure. With its HQ in Hillside, New Jersey, and with operations across the U.S., it offers dredging, heavy lift, towing, marine demolition, diving, and other critical marine infrastructure solutions, with salvage operations spanning the globe.
With a fleet of more than 70 specialised vessels, over 1,000 linear feet of berth space, and an estimated daily spoils processing capacity of 4,500 cubic yards in the New York and New Jersey harbours, Donjon Marine and its team of over 270 employees specialise in maintaining navigable waterways and accessible harbour infrastructure, responding to maritime emergencies, and delivering complex infrastructure projects across the U.S. and abroad.
Donjon Marine also operates a shipyard in the Great Lakes, equipped with a 1,250 feet by 120 feet by 22 feet (depth over sill) dry dock and has more than 200,000 square feet of production area on 44 acres of land.
The company will continue to operate under the Donjon Marine brand and John A. Witte, Jr. will continue to lead the business as its CEO, alongside Thomas and Paul Witte, as part of the platform’s executive team. In addition, Thoroughbred LLC., led by Co-Founders and Managing Partners Charles Wesley and Aaron Bowlds, will serve as industrial partner in the platform.
