The two countries agreed to the pipeline in December 2016 and launched feasibility studies ending with a plan to build the pipeline onshore and offshore, it said.

“For economic, political, legal and security reasons, the choice was made on a combined onshore and offshore route,” Morocco’s National Office of Hydrocarbons and Mines (ONHYM) and the Nigerian National Petroleum Corporation (NNPC), the two authorities supervising the project said in the joint declaration.

“The pipeline will be 5660 km (3516.96 miles) long and its CAPEX has been defined,” the declaration said, adding that construction will be in phases covering 25 years.
