Nigeria’s ₦70 Trillion Blue Economy Opportunity: Why the Sea Could Be the Next Big Business Frontier

When Nigerians talk about where the country’s money comes from, the usual answers are predictable: oil, taxes, borrowing and government revenue. There is, however, another enormous economic space that receives far less attention than it deserves: the sea.

Nigeria has an extensive coastline, navigable rivers, ports and an enormous maritime ecosystem connecting the country to international trade. Every day, ships bring goods into Nigeria and transport Nigerian commodities to markets around the world.

Cars, rice, machinery, fuel, electronics and industrial equipment arrive through our ports. Crude oil and other commodities leave through the same maritime network.

And every vessel involved in this movement generates economic activity.

There are shipowners, seafarers, freight forwarders, insurers, banks, logistics companies, port operators, ship repair businesses, marine engineers, technology providers, security companies, lawyers, consultants and countless other businesses involved in the maritime value chain.

The critical question for Nigeria is therefore not simply how much passes through our waters?

It is:

How much of the value created by our maritime economy stays in Nigeria?

That question has become increasingly important as Nigeria looks beyond oil and seeks new sources of economic growth.

The Business Behind Nigeria’s Waters

The idea of the Blue Economy goes far beyond fishing.

It encompasses economic activities connected to oceans, seas, rivers and waterways, including shipping, ports, logistics, fisheries, offshore energy, shipbuilding and repair, marine tourism, marine technology and other related industries.

For entrepreneurs, this represents a massive ecosystem of potential businesses.

Yet Nigeria’s maritime economy has historically faced challenges including infrastructure gaps, financing constraints, regulatory complexity and limited participation by indigenous businesses.

One person who has spent decades focusing on the legal and economic dimensions of this sector is Dr. Olisa Agbakoba, SAN, former President of the Nigerian Bar Association and a prominent maritime lawyer.

His involvement in maritime-sector reform stretches back decades and includes work around Nigeria’s Coastal and Inland Shipping (Cabotage) Act 2003.

The Cabotage Question: Who Owns the Business?

The Cabotage Act was designed, among other things, to promote Nigerian participation in domestic maritime trade.

The principle is straightforward: activities involving the transportation of goods and people within Nigerian waters should create opportunities for Nigerian-owned vessels, businesses and professionals.

The objective is similar to what happens in other strategic industries around the world: protect and develop domestic capacity so that local businesses can capture more value from economic activity taking place within their own territory.

But legislation alone does not automatically create businesses.

For entrepreneurs to take advantage of cabotage opportunities, they need access to capital, vessels, skilled workers, technology, insurance, infrastructure and a regulatory environment that allows businesses to operate competitively.

That is where the conversation becomes much bigger than maritime law.

It becomes a conversation about entrepreneurship and economic development.

The Oil Rig Question

One of the more fascinating legal questions in Nigeria’s maritime history concerns oil rigs.

In 2019, the Federal High Court in Lagos held in the Seadrill Mobile Units Nigeria Limited v. Minister for Transportation & Others case that drilling operations fell within the definition of coastal trade under the Cabotage Act and that drilling rigs fell within the Act’s definition of vessels.

However, the legal position became more complicated when the Court of Appeal subsequently overturned the Federal High Court’s position in a related case involving drilling rigs.

The issue illustrates an important point for businesses operating in regulated sectors:

The law matters.

A single interpretation of a regulation can affect registration requirements, fees, taxation, operating costs, investment decisions and the competitiveness of an entire industry.

For entrepreneurs entering the maritime and offshore sectors, understanding the regulatory environment is therefore just as important as having capital and technical expertise.

The ₦70 Trillion Question

In November 2025, Dr. Olisa Agbakoba wrote to the Minister of Marine and Blue Economy, Adegboyega Oyetola, outlining what he described as a pathway for unlocking up to ₦70 trillion in annual economic potential from Nigeria’s maritime and blue economy.

The figure is a projection of potential—not money currently being generated by the sector.

That distinction is important.

But the underlying question is perhaps even more important than the number:

What would Nigeria need to do to capture a much larger share of the economic value generated by its waters?

Agbakoba’s proposals include the creation of new legislative frameworks and amendments to existing maritime laws, alongside institutional reforms intended to improve the sector’s ability to attract investment and generate economic value.

One proposal receiving particular attention is the activation of the Cabotage Vessel Financing Fund, which was established to support Nigerian shipowners and help develop domestic shipping capacity.

The reasoning is straightforward.

If Nigerian law expects Nigerian businesses to participate in domestic maritime trade, those businesses must have access to the capital required to acquire and operate competitive vessels.

From Policy to Business

This year’s World Maritime Day theme provides an appropriate framework for the conversation.

The International Maritime Organization has selected “From Policy to Practice: Powering Maritime Excellence” as the theme for 2026 and 2027. The focus is on turning maritime rules and commitments into practical implementation and measurable results.

For Nigeria, that message has particular significance.

The country has no shortage of policies, committees, frameworks and development plans.

The bigger challenge is implementation.

A policy that never translates into infrastructure does not create jobs.

A law that does not translate into functioning institutions does not create competitive businesses.

And an economic opportunity that cannot be accessed by entrepreneurs does not create widespread prosperity.

Where Are the Entrepreneurs?

This is where Nigeria’s blue economy becomes particularly interesting.

The conversation should not be limited to government and large corporations.

There are opportunities for SMEs, startups, investors and professionals across the maritime value chain.

Think about:

• Marine logistics and transportation

• Ship maintenance and repair

• Marine engineering

• Freight forwarding

• Port-related technology

• Maritime security

• Insurance and financial services

• Marine software and digital platforms

• Cold-chain logistics

• Fisheries and aquaculture

• Marine environmental services

• Ship chandling and supplies

• Training and certification

• Maritime legal and consulting services

• Data and tracking technologies

• Marine tourism and hospitality

The opportunity is not necessarily in owning a massive ship.

Sometimes the opportunity is in building the technology, service or infrastructure that makes the ship’s journey possible.

That is how modern business ecosystems work.

The Bigger Economic Question

Nigeria’s maritime economy presents a broader lesson about entrepreneurship.

Countries do not necessarily become wealthy simply because they possess natural resources.

They become wealthier when businesses, institutions and individuals develop the capacity to capture value from those resources.

Nigeria exports crude oil, but the wider oil and gas value chain demonstrates how much economic activity can exist around a single commodity.

The same thinking can be applied to the sea.

A ship entering Nigeria creates opportunities far beyond the cargo it carries.

There is transportation.

There is insurance.

There is finance.

There are port services.

There is customs and trade facilitation.

There is warehousing.

There is logistics.

There is technology.

There is maintenance.

There are professional services.

There are thousands of potential business relationships.

The question is whether Nigerian businesses are positioned to capture a meaningful share of that value.

From the Sea to the Nigerian Entrepreneur

The blue economy should therefore not be viewed simply as another government programme.

It could become a significant business ecosystem.

But unlocking that opportunity will require more than announcements.

It will require investment, infrastructure, financing, regulatory clarity, technical skills, indigenous participation and consistent implementation.

And perhaps most importantly, it will require entrepreneurs to start looking at the maritime sector differently.

Nigeria’s next major business opportunities may not always be found on the streets of Lagos, Abuja or Port Harcourt.

Some may be found on the water.

The ₦70 trillion figure should therefore be treated as a proposition to examine, debate and test—not as guaranteed revenue.

The real opportunity lies in determining how much of Nigeria’s maritime economic potential can actually be converted into businesses, jobs, investment and sustainable national value.

That is the conversation Nigeria’s entrepreneurs, investors, policymakers and business leaders should be having.

RCT Network asks:

What is the biggest business opportunity you see in Nigeria’s blue economy?

What is currently preventing Nigerian entrepreneurs from participating more strongly in the maritime sector?

And if Nigeria succeeds in significantly expanding the economic value generated from its waters, which areas of the economy should benefit first?
