Following the delivery of the 60-meter NNS Lana hydrographic survey vessel from Ocea earlier this year, the Nigerian Navy has placed an order for a 35-meter hydrographic survey vessel from the French shipyard.

On October 12, Ocea announced a deal for an OSV 115 SC-WB vessel from the company’s auxiliary vessel fleet. “It would help the Nigerian Navy to complete its understanding of its maritime territory in support of the OSV 190 NNS Lana,” Ocea stated.

The OSV 115 SC-WB is intended for a variety of duties such as oceanographic/hydrographic operations/survey, oil spill operations, general patrol, search and rescue, and diving assistance.

A multibeam echosounder, a single beam echosounder, water collection, storage, and analysis equipment, and a wet laboratory will be carried on board. A 5.6-metre hydrographic boat outfitted for surveys in tiny and very shallow seas will also be carried.

The vessel can carry 12 crew and guests and has a top speed of 12 knots and a range of 3 000 nautical miles at 10 knots.

In recent years, the Nigerian Navy has received a substantial number of warships from Ocea, including the NNS Lana, two 35-meter FPB 110 Mk II patrol boats, and two 17-meter C-Falcon interceptors.

The NNS Lana arrived in Nigeria on May 17th, replacing the former NNS Lana, which had been decommissioned a decade before. The vessel (A499) is specifically designed and manufactured to allow the Nigerian Navy to conduct hydrographic and oceanographic surveys. It can also conduct geophysical investigations, search and rescue missions, and patrol responsibilities. The ship is outfitted with survey equipment and a 7.6-metre boat for shallow water surveys. The ship is equipped with an Automatic Weather Station (AWS), wet and dry labs, scientific and technical workshops, and survey data operations and processing rooms.

Two MTU engines, three CAT main generators/one emergency generator, an electric propulsion system, and other auxiliaries are among the machinery. The electric propulsion, which operates at survey speed, is specifically installed to reduce data distortion caused by industrial noise. The ship has a top speed of 14 knots and a crew capacity of 50 people.

The two new hydrographic survey vessels will aid the Nigerian Navy’s Hydrographic Department in conducting hydrographic surveys and charting of the country’s seas. They will also provide Nigeria with the option to participate in the General Bathymetric Charts of the Oceans (GEBCO) Seabed 2030 project and the Global Multi-Resolution Topography (GMRT) synthesis project, which will ultimately help Nigeria meet its SOLAS obligations (International Convention for the Safety of Life at Sea).

Over the last eight years, Ocea has supplied Nigeria with one FPB 98 Mk I patrol vessel, eight FPB 72 Mk II patrol vessels, two FPB 110 and two FPB 110 Mk II patrol vessels, and four C-Falcon interceptors.
