A large portion of the trade in UK takes place across the seas. As much as 90% of the goods are transported over the sea. The entire marine industry in UK comprises a million employees and contributes a whopping £46 billion to the economy of the United Kingdom. The industry boasts of exceptional quality of services as far as advanced manufacturing and design are concerned. Much of the success can be attributed to the strong academic base. The industry has also made a significant contribution towards dealing with the issue of climate change by leading the way when it comes to marine renewable technology. There are not many industries in the country that possess such a successful record of accomplishment as the Marine industry. The success has obviously not come overnight but has an excellent record of innovation, academic excellence, craftsmanship and advanced manufacturing to back its rise to success. These days knowledge based activity is extremely crucial and is equally important as manufacturing. The UK marine industry can be broadly divided into three sectors namely, the naval sector, the commercial sector and the leisure sector. The leisure sector comprises approximately 4200 businesses, a large majority of which are small and medium sized enterprises. These employ around 34,300 people and manage to earn around £3.16 billion of revenue every year. Of this about £1.25 billion is generated out of exports. The sector comprises leading manufacturers of sailing yachts and motors, equipment manufacturers, holiday companies, marinas and associated supply networks. The sector has witnessed a growth rate of 14% in the last four years. The naval sector comprises a few large companies that are strongly supported by the strategic supply chain and includes a number of small and medium sized enterprises. It employs around 24,000 people and generates revenue of £3 billion every year. The sector boasts of an impressive product line-up that includes submarines, equipments, warships and other high value systems. A large amount of the turnover is generated through equipment and systems and through the increasing number of exports. Important issues that affect the sector include a sustaining capability in the face of a waning Royal Navy fleet and new build programmes. The challenge lies in developing new international markets and ensuring increased cost efficiency over the entire life span of the products. The commercial sector, on the other hand, comprises maintenance, merchant shipbuilding, marine equipment, ship recycling, research and development, design and repair and conversion services. The commercial sector generates an annual turnover of approximately £1.6 billion and employs as many as 36000 people. The UK based companies have succeeded in increasing their market share in the Far East and believe that there are opportunities that need to be explored. The opportunities for growth in the sector exist in sectors such as conversion and ship repair. Then there is the emerging sector of marine renewable energy. This sector is engaged in the conversion of wave, wind and tidal energy into electricity. Though it is still in its initial days, the project is certainly one to look forward to in the coming years as countries attempt to utilise their offshore renewable resources to gather support for future energy requirements and handle climate change.
