Greek owners control the world’s largest merchant fleet: nearly 5,800 ships of 458 million deadweight tonnes, 19.1% of global capacity and 61% of the EU-controlled fleet [1]. More than 98% of that capacity carries cargo between third countries; in 2025 Greek ships made over 175,000 port calls in 171 countries, and they rank first worldwide in tankers and LNG carriers and second in dry bulk [2]. At home, shipping accounts directly and indirectly for 7–8% of GDP and about 200,000 jobs [1].
Operations and management. Ship operation is the daily coordination that gets each voyage done safely and on time: routes and weather, port calls and agents, cargo, fuel and charterers, all within international rules on navigation, security, pollution and working conditions. Ship management is the wider system around it – technical teams for maintenance, surveys and dry-docking, safety and crewing departments, and specialists in chartering, insurance, law, finance, IT and environmental compliance. A decision taken in an office in Piraeus can change what happens on a ship thousands of kilometres away – and the risks are real: in 2025 attacks on merchant ships and seafarers in the Red Sea, the Black Sea and the Strait of Hormuz exposed shipping to what the shipowners describe as unprecedented risk [1].
The green transition. The IMO’s 2023 strategy targets net-zero greenhouse-gas emissions from international shipping by or around 2050, with cuts of at least 20% (striving for 30%) by 2030 and 70% (striving for 80%) by 2040 against 2008, and 5–10% zero or near-zero fuels by 2030 [3]. Its Net-Zero Framework, combining a global fuel standard with carbon pricing, was approved in 2025, but adoption was postponed in October 2025; a new decision is scheduled for December 2026 [4]. Greek owners are already renewing their fleets: in 2025 some 725 ships worth about $60 billion were on order [11]. In Europe, companies already surrender emission allowances under the EU ETS – for 100% of intra-EU voyage emissions from 2026 – and FuelEU Maritime requires the greenhouse-gas intensity of ships’ energy to fall by 2% from 2025 and by 80% by 2050 [5].
Digital ships, human skills. Maritime single windows for ship–port data have been mandatory since 2024, and in March 2026 the IMO’s Facilitation Committee approved a Strategy on Maritime Digitalization, due for adoption in 2027, together with mandatory cyber-security measures for those systems [6]. Technology will not replace people: a DNV study for the Maritime Just Transition Task Force estimated that up to 800,000 of the world’s nearly two million seafarers may need extra training by the mid-2030s to handle new fuels safely [7].
From school to the sea. Greece trains its officers at 12 public Merchant Marine Academies, including one in Chania: tuition is free, and six semesters of study plus at least 12 months at sea lead to a degree and a third-class master’s or engineer’s certificate [8]. For 2026–27 the academies offered 1,810 places, yet in 2025–26 only about 84% of places were filled [8, 9]; the shipowners’ SYN-ENOSIS programme also offers 365 scholarships for 2026–27 [12]. For BLUE OCEAN, which links schools with blue careers [10], shipping offers an authentic bridge between classroom and work: students can plan a voyage and compare fuel and route choices, calculate the emissions a company must report, or rehearse an emergency drill – and discover careers on the bridge, in the engine room, at ports, in technical offices and in digital and environmental services.
Leadership brings responsibility: safe operations, decent work for seafarers, protection of the marine environment and credible progress on emissions belong to the same professional culture. Presented honestly, Greek shipping is not only a national success story but a demanding, changing field in which young people’s skills are genuinely needed.
