Maritime transport remains essential to global trade, yet seafaring is still among the most hazardous occupations. Adverse weather imposes severe operational and cognitive challenges, especially during deck work requiring coordination and situational awareness. This study employs the Success Likelihood Index Method (SLIM) to quantify the human error probability in deck operations conducted under heavy weather. Expert judgments from five maritime professionals were used to rate and weight performance shaping factors: leadership and supervision, procedural arrangements, risk acceptance, experience, and time pressure. Findings indicate that experience and leadership and supervision most strongly influence task success, while bridge–deck communication showed the lowest success likelihood index. These results highlight that communication-intensive tasks are highly vulnerable to wind, motion, and noise disruptions during heavy weather. From a practical perspective, the study shows that strengthening communication protocols, incorporating scenario-based BRM and ISM training for heavy-weather operations, and retaining experienced personnel can significantly enhance operational reliability. The results also provide ship operators with a task-level risk profile that can support more targeted safety interventions on board.
