Bollinger Shipyards will refit the National Oceanic and Atmospheric Administration (NOAA) oceanographic research vessel Ronald H. Brown, the largest vessel in NOAA’s fleet at 274'. The work will be done at Bollinger Mississippi Repair, Pascagoula, Miss. The overhaul is expected to extend the life of the vessel, first launched in 1996, by an additional 15 years. The vessel refit is scheduled to be completed and redelivered to NOAA in August 2024. During the refit, the propulsion system will largely be replaced with new, more environmentally friendly diesel generators, renewal of the bowthruster and propulsion motors, new switchboards, control systems, and alarms. Additional ship systems that are scheduled to be upgraded include the potable water plants, sewage plant, uncontaminated seawater sampling system, HVAC systems, tank level indicators, navigational components, radar, overhead lighting, and ballast and exterior fuel tank vents. Bollinger will replace much of the ship’s piping, along with steel as identified by the American Bureau of Shipping (ABS).
