Heavy-lift derrick barge services are a Donjon priority. The company's floating heavy-lift equipment includes the 1000-ton capacity floating boomable shearleg Chesapeake 1000 which is based in Port Newark, NJ. Donjon's certified heavy-lift derrick barge fleet is used in a number of ways from cargo lifts to providing services in support of its salvage, construction and demolition activities.

Lashing/securing of cargo onto rail cars, deck barges and transporters is also an integral part of Donjon's heavy-lift services and is offered to customers in an effort to provide a true turnkey service.
