The US Navy's Ohio-class ballistic missile submarine USS Maryland (SSBN 738) has completed the engineered refuelling overhaul (ERO) at the Norfolk Naval Shipyard.

The ERO, which commenced in December 2012, is a major shipyard availability at the submarine's mid-life point to facilitate its operability for its entire design service life.

The ERO involved refurbishing and upgrading the vessel's systems, including the replacement of distilling plants with a reverse osmosis unit, installation of an upgraded 500kW motor generator, electric power plant work and upgrading the local area network (LAN).

"The Maryland project team held itself to high standards and had strong leadership with a focus on planning, communication and coordination." 

During the availability programme, the project team achieved a number of milestones, including setting a new best for the shipyard in safety performance on a SSBN availability; achieving record performance in the period from completion of hot operations to the start of its power range test programme; and a record performance on propulsion plant testing.

Shipyard commander captain Scott Brown said: "The Maryland project team held itself to high standards and had strong leadership with a focus on planning, communication and coordination.

"Every SSBN refit and maintenance period directly supports the next strategic deployment, which is the most pressing priority for the Department of Defence."

Constructed by General Dynamics, the USS Maryland is the 13th of the 18 Ohio-class submarines deployed into the US Navy.

The 109.73m-long vessel has a displacement capacity of 18,750t, is powered by a nuclear reactor, and can achieve speeds in excess of 20k.

USS Maryland is currently deployed into the Atlantic Fleet and homeported in Kings Bay, Georgia.
