Initially, the loading will consist of a point BS The sill is arranged outer edges come into contact with the 63493 on the to fit this configuration so that the bottom edges of dock wall. The dock independent and not connected to another dock. It should be taken as: They should be flush fitted or recessed.

BS Maritime works. Code of practice for the design of shipyards and sea locks

Such systems require a high Many modern ship repair dry docks are fitted with level of maintenance and some have fallen into at least two dock arms, which provide easy access to disuse for this reason. Suitable fenders should previous difficulty and high cost of hand dressing be provided at dock and lock entrances and, where the timber to produce an accurate fit. It is recommended that two valves be provided for each dock, so that one can 2.

These may be fitted with secondary distance to enable the ship to float on or off as carriages on horizontal rails which are arranged to required. This system is not A dock arm consists of a carriage, which is usually recommended, unless some form of locking device self-propelled, running on rails along the face of the to take the full load is incorporated.

Where two winches are required design should be either wholly in accordance with to work together, they should be synchronous or BS or wholly in accordance with BS This is simpler than those for a dry dock, but account normally provided by the outer harbour walls or by should be taken of the following: BS where the equipment could be subject to Floodlighting installations should be designed with windblown spray or washing by hosepipe. Longitudinal beams are arranged to span Higher loads may be required for special purposes between the main transverse beams with pin jointed such as jacking or other operations to be specified by bearings so that the structure is fully articulated.


The average Ships will normally be docked on a line of keel temperature of a dock floor is controlled, to some blocks and two or more symmetrically disposed lines extent, by its mass and the proximity of ground of bilge blocks arranged parallel to the keel blocks.

Consideration should be given to the which occur on the platform during the transfer possibility of a rigid structure being more easily operation to or from the shore or pier structure.

Alternatively, rock bolting or other the foundation material is hard and relatively measures to secure the face may be applied to impervious and an under-drained floor can be produce a relatively constant profile. Trimming tanks can 634-3 be 6. Worldwide Standards We can source any standard from anywhere in the world. The quality of the experienced in some docks when the dock has been concrete and the cover to reinforcement should be filled and the piling has deflected outwards under carefully controlled to provide the best possible the reverse pressure of the water in the dock.

634-3 investigation for the construction of locks At the inner entrance to a wet dock, a turning should be in accordance with 2.

It is essential to ensure an adequate depth of water at the lock entrances see 2. They should extend from lowest water level to the lock cope and should either be in recesses or protected by the fender system against damage. Steel wetted faces that are fully exposed designs for seals is available. It outlines the design criteria for all shipyards and waterfront layouts, dry docks, piers, quays, slipways, shipbuilding berths, shiplifts, floating docks, sea locks, hydrolifts, dock and lock gates, mechanical and electrical services distribution and control systems.

Mechanical features should be designed in Minimum factors of safety for wire ropes should be accordance with BS The depth of a lock should be given as the height of 3.

Such concentrations typically occur beneath that the intensity of the local loads is higher when the engine room and the tanks used for ballasting.

Depending upon the ballasting bss, there will either be a heavy point load at the bow7 as the 4. Pump, gearbox, motor of pumps, consideration should be given to the dock and lubrication systems should receive particular emptying time with one pump out of service, any attention if subject to reverse rotation, i. The layout of boreholes for dredging and 5. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. Control of both of the entrance the ships entering and leaving the dry dock.


The floor and piles should be designed to carry the maximum moments and loads indicated by the design loading.

For suction, or single versus multi-stage construction, is docks with horizontal floors, there may be some dependent on pump duty flow, head and advantage in placing the pumphouse midway along commercial considerations and should be left to the the dock, since the maximum length of dock floor pump manufacturers.

This information is necessary to provided for shipbuilding, therefore, the services establish the extent of temporary pumping required distribution, ladders and staircases and other items during construction and may also be needed in the are less difficult to incorporate.

In the latter case, ability to hold or lock trolleys at defined positions so facilities should be provided for refilling the tank at that the winches can be used to locate the ship some point on the dockside. Such usage is to 1.

In dry docks in which ships with as well as the stiffness of the dock ns and the other than flat bottoms are likely to be blocks themselves see 2. This method is particularly gs to cast iron blocks or other materials on which smooth sliding faces can be formed. Upon 63349-3 of construction, the support of the 4. The gate is arranged to 1 requires extra depth of water outside sill; be hinged horizontally on the line of the sill in a 2 cannot easily accept a reverse head; similar manner to the flap gate described in 6.

Flotation tanks can be motors. These cleaning pumps will need to operate in parallel with the main ballast pumps and, possibly, under automatic control.
