Offshore containers are bbs into 3 categories: A container for the transport of em cargo e. In addition to the pad eyes 122079-1 the lifting set, these containers may have side mounted lugs suitable for use with the lifting equipment mounted on a skip lift vehicle.

NOTE This may include, e. Primary structure is divided into two subgroups: Side and roof panels, including corrugated panels, are not considered to be part of the primary structure 3.

BS EN 12079-1:2006

NOTE Not all container walls are corrugated. It may either be fabricated especially for type testing or selected at random from a production series 3. Where design requirements are based on the gravitational forces derived from these values, those forces are indicated thus: Rg, Tg and Pg the units of which are in newtons or multiples thereof.

T design air temperature, i. NOTE Local impacts, e. For dedicated purpose containers e. Protruding parts doors handles, hatch cleats, etc.

Only the primary structure shall be considered rn the design calculations; however, on certain types of containers, e. NOTE 1 For containers with exposed aluminium, the danger of sparks caused by the impact of aluminium against corroded steel the thermite reaction should be taken into account.

NOTE 2 When preparing the specification for a service container, it is advised that the rating is chosen higher than the estimated fitted out mass, i. This will allow for changes in the amount and mass of equipment fitted in a container during its operational life, and it may bd be useful to be able to carry a certain amount of non-permanent equipment.

NOTE 3 For containers with special features, additional design requirements may apply.

See informative Annex for guidance. The 120791- load shall be taken as 2,5 R – T g evenly distributed over the container floor. For tank containers, the actual distribution of the tare mass shall be used for the calculations. Pad eyes shall be designed for a total vertical force of 3 Rg.

The force shall be considered to be evenly distributed between n – 1 pad eyes where n is the actual number of pad eyes. To determine the resulting sling force on the pad eyes, the sling angle shall be taken into account, so that the resulting sling force on each pad eye is calculated as 21079-1 For containers with only one pad eye, that pad eye shall be designed for a ns vertical force of 5 Rg. NOTE Containers without a roof may have insufficient strength and stiffness to pass the 2 point lifting test 7.

In order to avoid building prototypes that will not pass the test, the ability of an open top container to withstand the load occurring in the 2-point lifting test should be checked by a suitable calculation method.

In these calculations, the nominal yield stress of the material should not be exceeded. These calculations do not replace 120791 prototype testing.

Ideally, dynamic calculations or tests should be carried out to verify the ability of a container to withstand such loads. However, for most applications it shall be sufficient to carry out simplified static calculations as specified in 5.

When simplified calculations are used, and each beam is considered separately, any assumptions concerning support conditions shall be stated. This force may act in any horizontal direction on the corner post. On all other frame members in the sides the load may be considered as acting at right angles to the side. The calculated static equivalent stresses due to impact shall be combined with the lifting stresses resulting from static lifting forces Rg.

Equivalent stresses shall not exceed: For container posts and side rails of the bottom structure: In addition, the side rails and end rails in the base shall be able to withstand vertical point forces of 0,25 Rg at the centre span. If the deck is at an angle, the first impact will be on a corner.

Such impact forces cannot be readily simulated by static forces. As dynamic calculations would be very complex, it is usually sufficient to verify the strength by a vertical impact test as described in 7. NOTE The thicknesses may have to be increased beyond these values to take account of special considerations such as rating, design, corrosion allowances, the need for impact tests of the material, etc.

For other primary structure, the use of fillet welds shall be justified by design appraisal including calculations and consideration of failure modes. Locking devices shall be secure against opening of the doors during transport and lifting.

Double doors shall have at least one such locking device on each door, locking directly to the top and bottom frame. Locking arrangements shall be protected to prevent dislodgement by impact. Hinges shall be protected against damage from impact loads.

Doors shall be capable of being secured in the open position. If weathertightness is required, the doors shall be equipped with seals. When intermediate cargo decks are designed to support other than half the total payload, the design requirement shall be calculated accordingly. Each shall be designed to withstand a force of at least 10 kN. NOTE 1 A minimum of 12 is recommended. NOTE 2 Hinge type lashing points are preferred.

NOTE 1 Special requirements apply for fork pockets on tank containers for dangerous cargoes, see 5. NOTE 2 The bottom face of the pocket may be fully closed but it is recommended that openings be provided to facilitate maintenance and to minimize the risk of loose items being retained in the pockets which could subsequently fall out during lifting operations.

These openings should be dimensioned and positioned so as to 13 EN The minimum internal dimensions of the forklift pockets shall be mm x 90 mm.

Forklift pockets shall be located such that the container is stable during handling and driving with forklift truck.
