Nigeria is betting a deep sea port set to open early next year will help revive an economy grappling with soaring inflation, stagnating growth and slumping foreign investment.

Cargo ships currently wait as much as a month offshore before unloading cargo in Lagos, Nigeria’s commercial hub. But the planned opening in March of the Lekki Deep Sea Port, on the eastern edge of the city, has the potential to slash cargo wait times to two days, Mohammed Bello-Koko, managing director of Nigerian Ports Authority, said in interview. “It changes everything because Lekki will be faster, it has more space, and it is more modern,” Bello-Koko said. 

The first phase of the project will have a capacity of 1.2 million 20-foot containers. The launch of the Lekki project will mark the first time the capacity of the city’s ports -- which handle 90% of the country’s imports -- have been expanded in a quarter century, even as Nigeria’s population has roughly tripled. 

The $1.5 billion project is co-owned by the Nigerian government and Singapore-based Tolaram, which is Nigeria’s biggest food company, and state-owned China Harbor Engineering Company, which built it. It is operated by a subsidiary of French shipping giant CMA-CGM. Trial port operations will begin in December ahead of a full commercial start in March. 

Nigeria is Africa’s biggest economy and most-populous country. But inefficiency, corruption, decaying infrastructure and congestion at the Lagos ports have led to cargoes bound for Nigeria being diverted to Ghana and Togo, countries with economies that are a small fraction of its size, costing billions in lost revenues and raising local prices. 

When it is fully operational in 2023, the Lekki project will more than double the capacity of Lagos’s ports, and will accommodate far bigger ships, Koko said. “It is a game changer that will bring back most of the cargoes we are losing to neighboring countries,” Bello-Koko said. 

The government also plans to upgrade the existing ports and has received pledges from three multilateral lending agencies to raise $600 million for the modernization of Tin Can, one of the main ports. He did not name the agencies.

“We need to rehabilitate the port,” he said, noting that the city needs more than one functioning port. “If we allow it to collapse, it will be catastrophic.”
