R/V Atlantis arrives in home port for the first time in April 1997
A giant crane lifts Knorr in 1989 as the ship?s refit begins at McDermott Shipyard in Amelia, Louisiana.
Knorr and Melville have ranged the world ocean since their refits.
Midlife refit upgrades to Oceanus completed in 1994 included a one-third increase in laboratory space, from 1,054 to 1,390 square feet. Science berthing increased from 12 to 15, and an additional 4 berths are also available in a portable van. The heating-ventilation-air conditioning system was fully replaced, and new refrigerators and a freezer were installed along with new main and auxiliary exhaust systems. The ship was equipped with a rebuilt reduction gear, a new crane, a bigger A-frame, a new capstan, a new anchor windlass, and a new emergency generator. The main engine was overhauled and upgraded, and a new structure (forward shaded area) was built to house the pilot house, chart room, and communications room.
AGOR-24 was delivered to Scripps Institution of Oceanography in 1996 for operation as Roger Revelle.
