NOTE Local impacfs, e' 9. from hitting other deck cargo or rigid parts of the ship structure, may cause extreme l oads i n such condi ti ons. 5.1.2 To preventthe contai ners from overturni ng (ti ppi ng) on a movi ng deck, they shal l be desi gned to wi thstand ti l ti ng at 30 " i n any di recti on, wi thout overturni ng when l oaded at i ts maxi mum gl ross I EN 12079-1:2006 (E) mass, with the centre of gravity considered to be at the half height of the container. For dedicated purpose containers (e.9. bottle racks and tank containers) the actual centre of gravity shall be used. 5.1.3 Protrudi ng parts on the outsi de of the offshore contai ner that may catch other contai ners or structures shal l be avoi ded. Protrudi ng parts (doors handl es, hatch cl eats, etc.) shal l be so pl aced or so protected that they do not catch the lifting set. 5.1.4 Where contai ners are desi gned for stacki ng, and the l i fti ng set hangs over the si de of the top frame they shall be fitted with a method of protection for those exposed parts, e.g. corners raised to suffi ci ent hei ght above the frame and roof to prevent uni ntenti onal contact, wi th and damage to, the l i fti ng set. 5.1.5 Contai ners shal l be desi gned as structural frames (pri mary structure), wi th non-l oad beari ng cl addi ng where necessary (secondary structure). Onl y the pri mary structure shal l be consi dered i n the desi gn cal cul ati ons; however, on certai n types of contai ners, e.g. waste ski ps wi th trapezi um 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 contai ner as a monocoque constructi on. 5.1.6 Ip shal l not be hi gher than the (stati sti cal l y) l owest dai l y mean temperature for the area where the offshore contai ner i s to operate and i n no case shal l be hi gher than -20 "C. NOTE 1 For contai ners wi th exposed al umi ni um, the danger of sparks caused by the i mpact of al umi ni um 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, additionaldesign requirements may apply. See informative Annex for gui dance. 5.2 Structural strength 5. 2. 1 Gener al The requi red strength of a contai ner shal l be determi ned by cal cul ati on and veri fi ed by type tests, as descri bed i n Cl ause 7. 5.2.2 Li fti ng l oads 5.2.2.1 For desi gn l oads defi ned i n 5.2.2.2 and 5.2.2.3, no equi val ent stress l evel , d, , shal l exceed the fi gure cal cul ated as o" = 0,85 C, where: for steel: C: Re for al umi ni um: Basd materi al C = Ro.z where: wflffi,rFliffiffi TFP:?inr:_r=r: _ r "' i?i_t'B.ffi Heat affected zone C --0,7 f R* EN 12079-1:2006 (E) R*i s the tensi l e strength of al umi ni um B i s 0,8 for ISO Al Mg4,5Mn-HAR/M5083-H32 B i s 0,7 for al l other al umi ni um al l oys and tempers (see Table 4) 5.2.2.2 Lifting with lifting set The design force on the primary structure shall be calculated as2,5 Rg. g is the acceleration due to gravity (in m/s2 i.e. 9,80665). The internal load shall be taken as Q,5 R - T)S evenly distributed over the container floor. For tank contai ners, the actual di stri buti on of the tare mass shal l be used for the cal cul ati ons. Pad eyes shall be designed for a total vertical force of 3 Rg. The torce shallbe considered to be evenly distributed between (n - l) pad eyes where n is the actual number of pad eyes. To determi ne the resul ti ng sl i ng force on the pad eyes, the sl i ng angl e shal l be taken i nto account, so that the resulting sling force on each pad eye is calculated as follows: 3R. E - 6 ^ - , ' (n -l )cos v where: ,F is the resulting sling force, in newtons; r i s the actual number of pad eyes (for cal cul ati on purposes n shal l not exceed 4 and shal l be not l ess than 2); v i s the angl e between a sl i ng l eg and the verti cal , i n degrees and shal l be assumed to be 45' unless otherwise specifled. 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 lifiing test should be checked by a suitable calculation method. ln 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 Li fti ng wi th forkl i ft truck The wei ght of the l i fti ng set shal l be taken i nto account when cal cul ati ng the strength of the fork pockets.

However, for most applications it shal l be suffi ci entto carry out si mpl i fi ed stati c cal cul ati ons as speci fi ed i n 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.

For hori zontal i mpact on tank contai ners for dangerous cargoes see 5.5.4. 11 EN 12079-1:2006 (E) 5.2.3.3 Verti cal i mpact A vertical impact test shall be carried out in accordance with 7.4. ln 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: oe=C ( see 5. 2. 2. 1) Calculated deflections shall not exceed: l n 2s0 where: 1, i s the total l ength of the rai l . NOTE Maximum vertical impact forces are likely to occur when a container is lowered onto the deck of a heaving supply vessel. lf the deck is at an angle, the first impact will be on a corner.

Several of these certification schemes are or may be applicable for offshore contai ners as defi ned i n thi s standard. General certi fi cati on requi rements for offshore contai ners The International Maritime Organization. lMO, has issued guidelines for certification of offshore contai ners, i n ci rcul ar MSC/Ci rc.860. Thi s ci rcul ar i s i ntended to gui de nati onal authori ti es i n devel opi ng approval and certi fi cati on requirements for offshore containers. lt recommends that new offshore containers be approved, prototype tested and certified by duly authorized bodies. l nternati onal Requi rements for Frei ght Contai ners Frei ght contai ners, as defi ned i n the l nternati onal Conventi on for Safe Contai ners (CSC), are requi red to be certified to that convention. Offshore containers are usually not covered by the CSC. However, offshore contai ners that fal l wi thi n the defi ni ti on of a contai ner i n the CSC, and whi ch are used internationally for transport of cargo, must also be certified to that convention. Tank Contai ners for Dangerous Goods Al l tank contai ners i ntended for mari ne transport of dangerous goods need to be certi fi ed to the Internati onal Mari ti me Dangerous Goods Code (the IMDG Code). Tank contai ners bui l t after January 1' t 2003 must be bui l t and certi fi ed accordi ng to the requi rements for UN type tanks (Ch.6.7 i n the IMDG code). Tank contai ners bui l t before that date may be i n accordance wi th Chapter 13 of the ol der IMDG code (i .e up to amendment 29 of that code.) Tank contai ners that are certi fi ed accordi ng to these requi rements are al so al l owed for road and rai l transport, Addi ti onal requi rements for offshore servi ce contai ners ln addition to the transport related requirements covered by EN 12079 and the regulations described above, offshore contai ners may be desi gned or equi pped for speci al servi ce tasks, (e.9. l aboratori es, control stations, workshop, accommodation, stores, power plants, process units). Such servi ce contai ners, as defi ned i n paragraph 3.1.2, may be subj ect to safety regul ati ons appl i cabl e on the offshore i nstal l ati ons where they are used. The safety regul ati ons may appl y for vari ous types of i nstal l ati ons, systems and equi pment i n the contai ner.
