The Input of Human errors as constituents to Marine Accidents in the Niger Delta, Nigeria. A Quantitative Approach

Abstract

The number of causalities, injuries, loss of life and properties accompanied with marine pollutions per year recorded from marine accident is quite alarming in Niger Delta. A very large proportion of these accidents have been attributed to human errors. This study elucidates the main human factors or errors that have contributed to the incidence of marine accident in the Niger Delta navigational waters. A descriptive and quantitative survey was carried out and data collected using well-structured questionnaires distributed to 400 respondents, out of which 287(71.8%) was retrieved. An appropriate statistical tool (SPSS Softwares-2010 Chicago version) such as multiple logistic regressions using The Adjusted Odd Ratio (AOR) was employed for predictors/independent variables at 95% confidence interval. The socio- demographic results showed that majority (78.4%) of the respondents are of sound mind with over 10 years of working experience. The P-value is 0.02 for the multiple logistic regressions; there exist a statistically significant relationship within the predictors (independent variables) and incidence of marine accident in the Niger Delta. The constituents of Human errors do not contribute equally towards marine accident incidence. Six(6) out of the ten(10) identified human related factors/error namely crew fatigue, unruly behaviour, unsafe vessel speed, commercial pressure from management, lack of maintenance culture, organisational structure/inadequate safety culture were frequent human causes of marine accident and are significantly related to safety performance. The highest ranking human error/factor is unsafe vessel speed of about 3.01 times higher odds of occurrence of marine accident while the least human factor is the influence of drugs and alcoholism with just 1.01 times higher odds. It is advisable for mariners to have positive and robust safety culture in place. Employers should recognise, encourage and reward Staff with impressive s
