"Numerous development has been already made in many areas of marine engineering in the past few years. A greater emphasis is now being placed on the cost-effective operation of ships. The marine engineer is required to understand the working principles, construction and operation of all the machinery items in a ship. The need for correct and safe operating procedures is as great as ever. There is considerably more legislation which must be understood and complied with, for example in relation to the discharging of oil, sewage and even black smoke from the funnel. Engineers must now be more environmentally aware of the results of their activities and new material is included in this revised edition dealing with exhaust emissions, environmentally friendly refrigerants and fire extinguishers. The aim of this video is to simply explain the operation of all the ship's machinery to anyone with an interest in ships' machinery or a professional involvement in the shipping business should find this book informative and useful." -From a Brilliant Marine Engineer
