The Langevin is a French research ship owned by the Compagnie Maritime Nantaise in Nantes .

history

The ship was built under the hull number 830 at the Halter Marine shipyard in New Orleans as an offshore supply for Acadian Marine Service and delivered in July 1980. The ship, which came under way as the Acadian Navigator , was the first of four identical offshore suppliers for the shipping company. Together with two other offshore suppliers with slightly different data, the ships formed the Mariner class named after the type ship Acadian Mariner .

In 1986 the ship was renamed the Nicor ​​Navigator . NICOR took over Acadian Marine Service in the early 1980s.

In 1987 the ship was involved in the search for the wreck of the Central America , which sank off the US state of Georgia in September 1857 en route to New York .

The ship was sold to the Compagnie Maritime Nantaise in 1990 and converted into a research ship. It is available to the French Navy as an auxiliary ship and the Naval Group , which emerged from the Direction des Constructions Navales in 2017, for defense research and development.

Technical specifications

The ship is powered by diesel-electric technology . The ships of the class were the first offshore suppliers with diesel-electric propulsion. The two propellers are of two electric motors, each with 1325  kW power driven. For electricity generation are three two-stroke - sixteen-cylinder diesel engines from General Motors (type: 16V149TI) are available, the three generators, each with 1,125  kVA apparent power drive. Furthermore, a harbor and emergency generator with 60 kW output (75 kVA apparent output) is available.

The deck superstructures with the bridge are in the front area of ​​the ship. Behind it was an open working deck extending over about two-thirds of the length of the ship. During the conversion to a research ship, a large part of the working deck was built over to create space for the necessary rooms such as laboratories, lounges and additional cabins.

The hull of the ship is reinforced with ice . The bollard pull of the ship is 87 t
