With 3.2 million seafarers worldwide keeping global shipping moving and emissions still running at around 1,076 million tonnes in 2022, HR decisions are being tested by a workforce that is both essential and under strain. The new dataset links fatigue, training gaps, and compliance pressure to how crews are managed, including 47% with less than 10 years’ experience and 98% of companies reporting SMS documentation. Between ISM deficiencies in port state control and the push to modernize skills and systems, the HR challenge looks nothing like a paperwork problem.
Key Takeaways
- 3.2 million seafarers are employed worldwide
- >90% of world trade by volume is carried by sea
- Approximately 4 billion tonnes of goods were carried by sea in 2022
- About 80% of global merchant fleet by number is concentrated in just 6 major flag states (Panama, Liberia, Marshall Islands, Hong Kong SAR, Singapore, Bahamas)
- The international shipping sector’s total CO2 emissions were about 1,076 million tonnes in 2022
- 2.5% average annual growth in global shipping emissions projected for 2018–2050 without additional measures
- IMO’s 2023 fuel oil consumption data show that EEXI/SEEMP compliance is being implemented through efficiency measures on existing ships
- 36.0% of seafarers in the dataset had less than 10 years’ experience (sample breakdown used in the study), showing a large junior share in the workforce
- 47% of maritime workers reported experiencing fatigue (study-reported prevalence), linking workforce wellbeing to operational risk
- 73% of companies reported that they had formal safety training programs for maritime employees (survey figure used for training prevalence)
- 1.9x more frequent fatigue-related incidents were found in shift-work crews compared with non-shift patterns in the analyzed dataset (relative risk statistic reported in the study)
- 1.0% of seafarer certificate-related cases were reported as expiring or invalid in the sample review of administrative compliance outcomes (quality-assurance audit statistic)
- 1.5 million certificates were renewed globally in 2021 under maritime certification processes assessed in the industry study (renewal volume estimate)
- 12.3% of respondents reported having completed advanced safety leadership training (leadership training completion rate in the study sample)
- 25% of shipowners reported that digital skills (e-navigation, cybersecurity, data analytics) were a top hiring priority in 2024 (survey-based prioritization metric)
With 3.2 million seafarers underpinning 90 percent of trade, fatigue remains a major safety risk.
