Floating docks

The pump will be placed on a floating dock that is just a few feet above the river level, so that the net positive suction head (NPSH) will be adequate. The maximum height from the bottom of the barge to the pump will be 20 ft. 

Option 4 - ship cutting within a floating dock and making up of a RC imit complying with the requirements for protracted waterborne storage. 

The dock-reequipping designer (the Western Design Office) has already performed the relevant estimates for V960 design floating dock reequipping. 

Lack of a prepared floating dock to ship both NSs and made-up RC units to Primorskiy Kray for completing their dismantlement and RC making up followed by storage at a special pad of LSC and... 

Transfer of NS and RC imits using an appropriate floating dock represents a more promising option from the technical and environmental safety considerations.

Sea disposal could be carried out in the following way, similar to the approach used during the Soviet period as discussed in section 2. The reactor vessels and the primary circuits are drained for water and filled with a material like furfurol or a low melting point metallic alloy to fix the damaged fuel and the control rod and to decrease the release of activity to the environment. If need be, additional material, e.g. concrete may be added to the reactor compartment to reduce the radiation level around the submarine. At the same time the floatability of the submarine must be ensured. After these preparations the submarine is transported out to the sea to a proper place, where the submarine is disposed of by sinking. Depending on the state of the submarine, it may by towed to the disposal area or it may have to be transported in a floating dock or by some other means. 

The moisture resistance, low cost, and low-density closed-cell structure of many cellular polymers resulted in their acceptance for buoyancy in boats, floating docks, and buoys. Because each cell is a separate flotation unit, these materials cannot be destroyed by a single puncture. Foamed-in-place polyurethane between thin skins of high tensile strength is used in pleasure craft [98]. Other cellular polymers that have been used where buoyancy is needed are produced from polystyrene, polyethylene, poly(vinyl chloride), and certain types of rubber. Foams made from styrene-acrylonitrile copolymers are resistant to petroleum products [99,100]. 

In general, cathodic protection in seawater is classified into (1) inshore purposes for pipelines, tanks and stmctures, (2) stmctures and ships immersed and active in seawater, and (3) those that are inactive or stationary in seawater. A variety of static stmctures including floating docks, chains, light ships, nets and so forth in various shapes and sizes are protected by (1) anodes directly and closely mounted... 

Definition as used in this section Marine service station shall mean that portion of a I property where flammable liquids used as fuels are stored and dispensed from fixed equipment on shore, piers, wharves, or floating docks into the fuel tanks or self-propelled craft, and shall include all facilities used in connection therewith. 

The philosophy governing the FPU layout is as follows. The starboard side ( clean side ) facing the coast has been equipped with facilities for coupling to a floating dock, providing continuous plant communication and high-voltage terminals for electric power transmission to the coast. 

Specialists/contract workers cany out the repairs for this particular vessel in the floating dock. Should a failure occur during operation at sea, temporaiy repair is carried out by the crew and the equipment is kept operating in the abnormal condition. No records are kept of any temporary repairs done on board, however, a repair list is compiled by the C hief Engineer for the equipment to undergo permanent repair work at the next docking . 

It has been observed that many fishing vessels call into a floating dock once a year to carry out a complete inspection/repair/overhaul of equipment on board. These repairs and overhauls are normally carried out by yard workers or specially contracted personnel. These vessels also come in for dry-docking every 3 to 5 years (depending on the condition of the vessel) to carry out repairs on seawater valves, replacement of hull anodes, inspection of propeller, tail shaft and rudder and any other fitting which lies beneath the water line.
