Seaports are important for the economy of each country. Given the position in coastal areas and the great variety of substances handled there, ports can be regarded as complex systems from the environmental point of view. They tend to be associated with water and air pollution; soil contamination; dust and noise problems; the generation of waste; dredging operations; movements of ships, lorries and trains; warehouse storage of hazardous substances; etc. Navigational safety is an important factor to be considered as far as port safety is concerned. In the U.K., the guidelines on port safety were originated form 'Safety in Docks-Docks Regulations 1988 and Guidance'. Following the 'Sea Empress' disaster in 1996, a review of the Pilotage Act 1987 was published in 1998. The outcome of the review was the recommendation of a development of a 'Marine Operations Code for Ports'. Consequently, the process of enhancing management control systems for the safety of navigation in ports was initiated. In this course work, the following are required: 1. Critically anaiyse one selected serious accident due to navigational errors within port waters and justify the need for navigational safety assessment in port waters 2.

You are required to use flow diagrams, bullet points, tables and figures where necessary 5. References need to be listed and quoted appropriately. 6.
