Healthier Ocean, Healthier Lives: Mercy Ships Seafarers Promote Sustainability While Serving Humanity

FREETOWN, Sierra Leone, September 25, 2025 – Mercy Ships is celebrating this year’s World Maritime Day by placing the spotlight on its crew of volunteer seafarers who not only dedicate their skills to serving vulnerable communities but also embody the theme Healthier Ocean, Healthier Lives through sustainable maritime practices.

With the world’s oceans providing livelihoods, transport, and food security for billions, the responsibility to safeguard marine ecosystems has never been greater.

For Mercy Ships, whose floating hospitals depend entirely on safe seas, the principle of Healthier Ocean, Healthier Lives is more than a slogan—it is a lived commitment.

Emmanuel’s Journey: From Oil Tankers to Humanitarian Service

Few stories capture this spirit better than Emmanuel, a 34-year-old Nigerian maritime officer currently serving on the Global Mercy™.

Having spent years navigating oil tankers in the commercial sector, Emmanuel mastered navigation, seamanship, and cargo operations.

Yet he felt a deeper calling: to use his maritime expertise in humanitarian service.

In 2024, he joined Mercy Ships on board the Africa Mercy®, where he witnessed firsthand the life-changing impact of surgical care.

“It was mind-blowing to see that in just one field service, the ship carries out over a thousand surgeries,” he recalled. “I’m happy this is happening in Africa, and I get to be a part of it.”

His journey reflects how seafarers can connect their professional expertise to a greater purpose, embodying the essence of Healthier Ocean, Healthier Lives—where maritime service not only enables trade but also sustains lives through medical access.

Sustainable Practices Onboard Mercy Ships

Mercy Ships recognizes that its mission would be impossible without healthy oceans. As such, sustainability is woven into daily operations:

Eco-friendly systems: Bio-reactor sewage plants and green cleaning products ensure only clean water leaves the ships.

Biodiversity protection: Ballast water treatment systems prevent the spread of invasive marine species across ecosystems.

Energy efficiency: The Global Mercy was designed to use 15% less energy through advanced air-conditioning systems.

Water conservation: Recycling processes reclaim up to 50% of water, while a “two-minute shower” policy encourages mindful usage.

Waste management: Medical waste is safely incinerated onboard, plastics are minimized through reusable bottles, and electronic waste is responsibly recycled in Europe.


Through these measures, Mercy Ships demonstrates how practical steps can turn the maritime industry into a force for both social good and environmental protection—key to realizing Healthier Ocean, Healthier Lives.

World Maritime Day: A Shared Responsibility

This year’s World Maritime Day theme—“Our Ocean, Our Obligation, Our Opportunity”—aligns seamlessly with Mercy Ships’ values.

With 40% of the world’s population living along coastlines and 95% of trade dependent on shipping, the health of oceans is directly tied to human well-being.

“Our ships sail because the ocean allows them to,” Emmanuel said. “It is our responsibility to respect the waters we navigate, because they are alive, and they connect us all.”

His words capture the deep link between service, sustainability, and humanity’s shared future.

By upholding Healthier Ocean, Healthier Lives as both a guiding principle and daily practice, Mercy Ships offers a model of how maritime organizations can balance operational goals with stewardship of the seas.

Inspiring Future Generations of Seafarers

Mercy Ships is also inspiring the next generation of seafarers to see beyond commerce and embrace service. Emmanuel encourages others to volunteer:

“I definitely recommend serving on Mercy Ships, even if it’s just once. It changes your outlook on how the maritime industry should operate.”

Through training, professional development, and lived experiences of sustainability, Mercy Ships equips maritime professionals with tools not just for navigating waters, but also for safeguarding them.

This human capital investment amplifies the long-term vision of Healthier Ocean, Healthier Lives.
