Marine operations

Cupro-Nickels. At the present time, most marine operators agree that the cupro-nickels are the most useful material of construction for sea-water plants. Since World War II, the 90 Cu-10 Ni alloy modified with about 1.5% of iron has become well established. The lower nickel content results in a cost advantage over the 70 Cu-30 Ni alloy. Alloys containing 70 Cu-30 Ni or 80 Cu-20 Ni, each with added iron, are preferred by some designers to withstand more severe conditions. 

Elements that affect the integration of LNG with the prevailing energy and transport systems have been considered. For instance the ability of LNG to be used as fuel for prime movers in marine operations - as in Norway, and as vehicle fuel especially to fleets of busses and trucks operating within a region. 

In developing strategies to address the CW or BW threat, it is important to understand that the threat will present itself differently to different parts of the naval force. Ships operating in deep water face one set of risks. Ships operating close to shore face another. Ports, shore installations, and bases have their own vulnerabilities, both outside and within the continental United States. The logistics infrastructure presents its own problems in the face of CW or BW threats. And Marine operations have their own special vulnerabilities, as do activities associated with special operations forces. 

EC is effective in water treatment for drinking water supply, membrane pre-treatment, marine operation, and boiler water supply for small systems. It is very effective in treating colloids found in natural water by reducing turbidity and colour as well as removing suspended solids, oil and grease, iron, silicates, humus and microorganisms. A comprehensive summary of pollutants removed by EC is given in [24].

For marine operations, the wind strength is described in terms of the Beaufort Scale (see Box 4.2). 

Swell waves are waves generated at some distance from the site. They have longer periods than wind-generated sea waves and tend to cause more problems for marine operations. Swell does not exist on totally enclosed waters, however these waves can penetrate into enclosed waters even through small harbom entrances.

The use of nuclear reactors to drive ships has been promoted particularly among nautical nations. Commercial marine reactors include the Savannah in the USA, the Otto Hahn in Germany, and the Mutsu in Japan. They experienced marine operation but unfortunately the development had been cancelled after several years. Nuclear-powered ships require fi ee access to ports in the world, but unfortunately there were no sufficient number of ports to make the marine reactor s operation feasible. Some countries had accepted to prepare the ports, but doing this would still take time.
