The history of Investigator goes back to 2009 when the Australian Government allocated A$120 million for a new ocean-going research vessel to replace the 1972 built RV Southern Surveyor. She is able to accommodate up to 40 scientists, for up to 60 days at sea at a time. Special features of the ship are a "gondola", similar to a winged keel, mounted 1.2 m below the hull, and two drop keels which can be lowered to a maximum of 4m below the hull to carry scientific instruments below the layer of microbubbles created by the movement of the ship’s hull through the water. Such instrumentation includes acoustic mappers and a pelagic sediment profiler to produce maps of the sea floor. The hull and the machinery of the ship have been designed to operate as quietly as possible to enhance its scientific capabilities. The vessel is able to map the ocean floor to any depth, search for resources, better understand fisheries, collect weather data 20km into the atmosphere and much more.
The history of the vessel’s management company goes back to 1991 when Australian National Line and Associated Steamships formed a joint venture, which saw the beginnings of ASP Ship Management. Today, the company is a globally engaged Ship Manager and Maritime Service Solutions provider with offices in Europe, the Indian Sub-Continent, Asia and Australasia.
