The Stennis Air Craft carrier put to sea over two decades ago at a cost of over four billion dollars. The vessel is designed to carry and support ninety fixed wing fighter planes and helicopters. She is an important part of the US nuclear fleet that had come due for critical maintenance to her power plant system components.

Hennigan is well known as a provider of best in class cleaning and maintenance services supporting heat transfer system efficiency improvement for Power Generation, Manufacturing, Marine/DOD and Municipal clients. In the case of the Stennis; the evolution included cleaning and maintenance of various components aboard the vessel. Hennigan used a variety of specialized cleaning systems to address a range conditions in order to ensure the success of the project. Hennigan worked closely with the G.C. Curtiss-Wright, the Navy and the Shipyard to produce an effective and safe work plan under difficult conditions, including Covid-19 protocols. All work was completed to the highest safety standard and incident free.
