3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 offshore container portable unit for repeated use in the transport of goods or equipment handled in open seas to, from and between fixed and/or floating installations and ships. NOTE The unit incorporates permanently installed equipment for lifting and handling and may include equipment for filling, emptying, cooling, heating, etc. Offshore containers are subdivided into 3 categories: 3.1.1 offshore freight container offshore container built for the transport of goods NOTE Examples of offshore freight containers are:  general cargo container: A closed container with doors;  cargo basket: An open top container for general or special cargo;  tank container: A container for the transport of dangerous or non-dangerous fluids;  bulk container: A container for the transport of solids in bulk;  special container: A container for the transport of special cargo e.g. garbage containers, equipment;  boxes, gas cylinder racks. 3.1.2 offshore service container offshore container built and equipped for a special service task, usually as a temporary installation e.g. laboratories, workshops, stores, power plants, control stations 3.1.3 offshore waste skip open or closed offshore container used for the storage and removal of waste NOTE Normally constructed from flat steel plate forming the load bearing sections of the container, with bracing in the form of steel profiles e.g. channel or hollow section, being fitted horizontally and/or vertically around sides and ends. In addition to the pad eyes for the lifting set, these containers may have side mounted lugs suitable for use with the lifting equipment mounted on a skip lift vehicle.



EN 12079-1:2006 (E) 7 3.2 permanent equipment equipment that is attached to the container and which is not cargo. NOTE This may include, e.g. lifting sets, refrigeration units, shelves, securing points, garbage compactors. 3.3 primary structure load carrying and supporting frames and load carrying panels. Primary structure is divided into two subgroups: 3.3.1 essential /non-redundant primary structure main structural elements which transfer the cargo load to the crane hook (i.e. forming the “load path” from the payload to the lifting sling) and will include, at least:  top and bottom side rails;  top and bottom end rails;  corner posts;  pad eyes;  although other primary structure may also be considered as essential /non-redundant. 3.3.2 non-essential primary structure other structural elements for which the main function is other than that described in 3.3.1 e.g. floor plates and protective frame members. Side and roof panels, including corrugated panels, are not considered to be part of the primary structure 3.4 secondary structure parts which are not considered as load carrying for the purposes of the design calculations, including the following components:  doors, wall and roof panels;  panel stiffeners and corrugations;  structural components used for tank protection only;  internal securing points. NOTE Not all container walls are corrugated. 3.5 prototype equipment item, used for type testing, considered to be representative of the product for which conformity is being claimed. It may either be fabricated especially for type testing or selected at random from a production series 3.6 owner legal owner of the offshore container or the delegated nominee of that body.



EN 12079-1:2006 (E) 8 3.7 lifting set items of integrated lifting equipment used to connect the offshore container to the lifting appliance 3.8 Visual inspection inspection of the characteristics of a product and determination of its conformity with specified requirements where applicable and based on professional judgement where general requirements apply 3.9 Visual examination

rating i.e. the maximum gross mass of the container including permanent equipment and
its cargo, in kg; but excluding the lifting set; T tare mass i.e. the mass of an empty container including any permanent equipment but excluding cargo and lifting set, in kg; P payload i.e. the maximum permissible mass of cargo which may be safely transported by the container, in kg; S mass of the lifting set in kg NOTE 1 P = R - T NOTE 2 R, T and P are, by definition in units of mass, kilograms (kg). 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. TD design air temperature, i.e. a minimum reference temperature used for the selection of steel grades used in offshore containers and equipment expressed in degrees centigrade; eσ von Mises equivalent stress, expressed in MPa or N/mm2; Re
specified minimum yield stress, expressed in MPa or N/mm2. 5 Design 5.1 General 5.1.1 An offshore container shall have sufficient strength to allow loading and unloading from supply vessels offshore operating in a sea state with significant wave heights of 6 m and to withstand impact from heavy seas. NOTE Local impacts, e.g. from hitting other deck cargo or rigid parts of the ship structure, may cause extreme loads in such conditions. 5.1.2 To prevent the containers from overturning (tipping) on a moving deck, they shall be designed to withstand tilting at 30 ° in any direction, without overturning when loaded at its maximum gross



EN 12079-1:2006 (E) 9 mass, with the centre of gravity considered to be at the half height of the container. For dedicated purpose containers (e.g. bottle racks and tank containers) the actual centre of gravity shall be used. 5.1.3 Protruding parts on the outside of the offshore container that may catch other containers or structures shall be avoided. Protruding parts (doors handles, hatch cleats, etc.) shall be so placed or so protected that they do not catch the lifting set. 5.1.4 Where containers are designed for stacking, and the lifting set hangs over the side of the top frame they shall be fitted with a method of protection for those exposed parts, e.g. corners raised to sufficient height above the frame and roof to prevent unintentional contact, with and damage to, the lifting set. 5.1.5 Containers shall be designed as structural frames (primary structure), with non-load bearing cladding where necessary (secondary structure). Only the primary structure shall be considered in the design calculations; however, on certain types of containers, e.g. waste skips with trapezium shaped sides, with only a non-stressed cover above the bracing where the pad eyes are attached, the whole structure may be considered as a primary structure, and the design calculations may treat such a container as a monocoque construction. 5.1.6 TD shall not be higher than the (statistically) lowest daily mean temperature for the area where the offshore container is to operate and in no case shall be higher than -20 °C. 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.e. to specify a certain payload even if the container is not intended to carry cargo. This will allow for changes in the amount and mass of equipment fitted in a container during its operational life, and it may also 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. 5.2 Structural strength 5.2.1 General The required strength of a container shall be determined by calculation and verified by type tests, as described in Clause 7. 5.2.2 Lifting loads 5.2.2.1 For design loads defined in 5.2.2.2 and 5.2.2.3, no equivalent stress level, eσ, shall exceed the figure calculated as e0,85Cσ=,
where: for steel: eRC= for aluminium: Base material 0.2CR=
Heat affected zone 0,7mCRβ= where:



EN 12079-1:2006 (E) 10 Rm is the tensile strength of aluminium
is 0,8 for ISO AlMg4,5Mn-HAR/AA5083-H32
is 0,7 for all other aluminium alloys and tempers (see Table 4) 5.2.2.2 Lifting with lifting set The design force on the primary structure shall be calculated as 2,5 Rg. g is the acceleration due to gravity (in m/s2 i.e. 9,80665). The internal 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 follows: ()31cosgRFnv=− where: F is the resulting sling force, in newtons; n is the actual number of pad eyes (for calculation purposes n shall not exceed 4 and shall be not less than 2); v is the angle between a sling leg and the vertical, in degrees and shall be assumed to be 45 ° unless otherwise specified. For containers with only one pad eye, that pad eye shall be designed for a total vertical force of 5 Rg. NOTE Containers without a roof may have insufficient strength and stiffness to pass the 2 point lifting test (7.3.3). 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 the prototype testing. 5.2.2.3 Lifting with forklift truck The weight of the lifting set shall be taken into account when calculating the strength of the fork pockets. The design force on the primary structure shall be calculated as 1,6 (R+S)g. The internal load shall be taken as (1,6 (R+S)-T)g evenly distributed over the container floor. Where fork pockets are intended only for handling of the empty container, the design load shall be taken as 1,6 (T+S)g.



EN 12079-1:2006 (E) 11 5.2.3 Impact loads 5.2.3.1 General Impact loads are dynamic loads of very short duration. 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 5.2.3.2 and 5.2.3.3 and to perform a drop test for vertical impact on corners, in accordance with 7.4. When simplified calculations are used, and each beam is considered separately, any assumptions concerning support conditions shall be stated. 5.2.3.2 Horizontal impact The main frame structure shall be dimensioned to withstand a local horizontal impact force acting at any point. 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: σe = C (see 5.2.2.1) The following values shall be used for the static equivalents to an impact force: For container posts and side rails of the bottom structure:
- 0,25 Rg For other frame members of the side structure, including the top rails:
- 0,15 Rg Maximum calculated deflections at these loadings shall not exceed: For corner posts and bottom side rails 1250n where: 1n is the total length of the rail or post in mm. For other frame members 1250n where: 1n is the length of the shortest edge of the wall being considered. NOTE 1n is a (nominal) reference length and will often be different from the actual span of a beam. For horizontal impact on tank containers for dangerous cargoes see 5.5.4.



EN 12079-1:2006 (E) 12 5.2.3.3 Vertical impact A vertical impact test shall be carried out in accordance with 7.4. 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. Equivalent stresses shall not exceed: eCσ= (see 5.2.2.1) Calculated deflections shall not exceed: 1250n
where: 1n is the total length of the rail. NOTE Maximum vertical impact forces are likely to occur when a container is lowered onto the deck of a heaving supply vessel. 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 7.4. 5.2.4 Internal forces on container walls Each container wall, including the doors, shall be designed to withstand an internal force of 0,6 Pg evenly distributed over the whole surface, without suffering any permanent deformation. 5.2.5 Minimum material thickness
The following minimum material thickness (t) requirements shall apply. a) for external parts of corner posts and bottom rails i.e. parts forming the outside of the container: for R≥
1000 kg, t = 6 mm; for R < 1000 kg, t = 4 mm. b) for all other parts of the primary structure: t = 4 mm; c) for secondary structure made from metallic materials: t = 2 mm; d) for waste skips of monocoque design (see 5.1) within an area of up to 100 mm from the side edges : t = 6 mm; for the remaining parts of the side structure: t = 4 mm. 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. 5.3 Welding Essential and non-redundant primary structural members shall be welded with full penetration welds. For other primary structure, the use of fillet welds shall be justified by design appraisal (including calculations and consideration of failure modes).



EN 12079-1:2006 (E) 13 Intermittent fillet welding of secondary structure is acceptable, however care shall be taken to avoid corrosion. 5.4 Additional design details 5.4.1 Floor Containe
