Vessel’s missions

It is 60m in length. The “LANA” will allow the Nigeria to have a better knowledge of its maritime territory and its Exclusive Economic Zone. The vessel will ensure the following missions:

  • Coastal and deep-sea scientific research and studies (hydrography, oceanography)
  • Fishing control
  • Surveillance of the Exclusive Economic Zone
  • Assistance and supplies to other boats
  • Helicopter winching operation
  • Towing of ships.


To carry out her missions, the ship is equipped with high-performance technical and scientific systems and equipment, in particular:

  • A deep water multibeam echosounder
  • A single beam depth-water sounder
  • A side scan sonar
  • A current meter
  • Means of sampling, storage and analysis of water, fish and sediment
  • Laboratory hardware and software
  • A 7,60 m Surface Vehicle equipped for data surveys along the coasts in small and very shallow waters.


Thus, OCEA OSV 190 SC-WB NNS LANA is equipped with the most up-to-date, accurate and high-performance sensors, to meet all mission requirements in coastal, deep sea and offshore waters.


Proven qualities

The NNS LANA benefitted from OCEA’s French Technology developed, through continuous innovation, over more than 30 years. The qualities, which were proven during the trials were confirmed by today’s results:

  • the excellent and optimized sea keeping of the OSV platform,
  • reduced impact on the environment: noise, radiation
  • high quality of the data collected even at high speed and in rough seas


Within the frame of a technical agreement between SHOM and OCEA, OCEA OSV 190 SC-WBs vessels already demonstrated their efficiency and capabilities as described in the article of “Hydro International” (May/June 2016).

The Nigerian Navy also ordered OCEA to provide logistic support services including crew, scientific and maintenance training to maintain the operational readiness of the “NNS LANA”, on-site technical assistance, spare-parts and tools, documentation.
