South Africa Needs More Nautical Scientists And Maritime Engineers If You Love The Sea These May Be The Careers For You

(MENAFN- The Conversation) When most people are asked to picture an engineer at work, they probably imagine a civil engineer in a hard hat at a construction site, a chemical engineer in a laboratory or an electrical engineer examining a complex circuit board. Very few, I'm willing to bet, visualise someone aboard a ship.

But, for those drawn both to engineering and a seafaring life, marine engineering and nautical science are ideal careers – especially in a country like South Africa, uniquely positioned where the Atlantic and Indian Oceans converge.

Over 90% of the world's goods are transported by sea . That means both marine engineers and nautical scientists are crucial to global trade, transportation and resource management. These professionals play a critical role in ensuring that vessels operate reliably, comply with environmental regulations and navigate safely through the world's oceans.

South Africa's Department of Higher Education does not distinguish between different types of engineering when collecting statistics about graduates. However, those of us in the marine engineering and nautical science space in academia can confirm the numbers are low. At my own institution, the Cape Peninsula University of Technology (CPUT) in Cape Town, between ten and 20 people graduate each year from these programmes. At another, Nelson Mandela University in the Eastern Cape province, around seven people graduate in these fields each year. With so few people studying these disciplines, the skills they impart are in high demand. The government's list of scarce skills for 2024 includes“marine engineering technologist”.

I'm an engineering lecturer in the Department of Maritime Studies at CPUT. There, I teach in both the Bachelor of Nautical Science and Marine Engineering programmes, lecturing on a variety of subjects, including mathematics and applied thermodynamics (the branch of physics that deals with the relationships between heat, energy and work).

Watching my students complete their degrees and start careers in marine engineering or nautical science has made it clear that this work offers a blend of adventure, technical challenge, and the opportunity to contribute to an industry that is essential to global commerce and environmental stewardship.

Whether it's designing cutting-edge marine technology or navigating the world's vast oceans, the maritime field promises a fulfilling professional journey.

Three universities – CPUT, Nelson Mandela University and the Durban University of Technology in KwaZulu-Natal – offer maritime studies courses aimed at those who intend to work at sea. A fourth, the University of KwaZulu-Natal, offers this degree with a focus on maritime law and logistics. There are also some specialised training institutions, among them the South African Maritime Safety Authority , that provide various qualifications and certifications.

You'll need to have taken mathematics, physical science and English in your school-leaving matric year, and to have passed them well. (Contact individual universities to find out their precise degree requirements.) A strong interest in and commitment to a career at sea or in the maritime industry more broadly is crucial.

Being a strong swimmer can be an advantage. But it is not necessarily a requirement. Students who do not know how to swim will typically have the opportunity to learn and develop their swimming skills as part of their training.

There are practical and theoretical components to these degrees. At our Granger Bay campus near the V&A Waterfront in Cape Town, for instance, we've set up a survival centre – a practical facility where students receive training to equip them for life at sea. It is fully equipped with three fully enclosed lifeboats, two open lifeboats, a rigid capsule, two fast rescue craft, a heated 12 x 7 metre pool, an underwater escape training dunker, various life rafts, life jackets, immersion suits, and more.

On the theoretical side, a Bachelor of Nautical Science programme focuses on the navigation and operation of ships. It encompasses navigation techniques, ship stability, cargo handling, meteorology, and maritime laws. This prepares students for careers as navigators in the merchant navy. (Not to be confused with the military navy – a merchant navy is a country's commercial shipping industry, which includes all the cargo and passenger ships that are registered under that nation and used for trade, transport and other non-military purposes.)

Some of our graduates have gone on to become ship's masters , also called captains – the highest ranking officer on any ship.

Marine engineering programmes, meanwhile, focus on the design, development, operation and maintenance of the mechanical systems and equipment used on ships and other marine vessels. This includes everything from engines and propulsion systems to refrigeration and steering mechanisms. Marine engineers ensure that these systems function efficiently and safely. They often work closely with naval architects to integrate these technologies into new ship designs or retrofit them into existing vessels.

Oceanic African countries, like South Africa, need people with these skills to harness the full potential of their maritime resources.

The development of local expertise in maritime engineering and nautical science is essential for ensuring safe and efficient maritime operations. It also helps to protect marine environments and contributes to global maritime trade. Skilled professionals in these fields help these countries take advantage of their maritime assets, promote economic growth and enhance their roles in international commerce.

As a proud lecturer, I am thrilled to see my students progress and develop both internationally and locally. Many have gone on to work in various exciting and prestigious roles around the world. Some have become ship's masters, navigating and managing large vessels on international waters, while others have taken on critical roles in maritime operations, port management and logistics in countries such as Singapore, Norway and the United Kingdom. Some have pursued careers in maritime law and policy. Their career paths reflect the diverse and global opportunities available in the maritime industry.
