BELBINS THEORY In this report I aim to explain belbins theory and then apply this theory to two emergency drills that I took part in whilst on-board the container vessel m/v Acapulco on the western coast of Mexico. The first drill that we carried out was a fire in the engine room drill followed by an oil spill drill. belbins theory is all about how teams are structured so that they perform at their best‚ with the belbins theory each team member has clear responsibilities and can see that every

CHAPTER 1 INTRODUCTION Students Industrial work experience scheme (SIWES) was established by ITF (Industrial Training Fund) in 1973 to solve the problem of lack of adequate practical skills required for employment in industries by Nigerian graduates of tertiary institutions. SIWES is an exercise created for students of higher education to enable them practice those things they have learnt theoretically in class. It also helps to expose students to the use of certain industrial equipment
