    This Standard for Certification was first published in May,
    1989 as "DNV Certification note 2.7-1 Offshore Freight Con-
    tainers". It was prepared because other regulations at the time,
    whether international codes, national requirements or rules
    published by Det Norske Veritas, did not specifically cover
    offshore containers. A revised Certification Note was issued in
    May 1995. The basic strength and design requirements from
    the original edition were retained.
    Many other standards, codes and regulations exist for contain-
    ers, container-like units and related types of equipment. Inter-
    national standards, codes and regulations considered relevant
    have been taken into account when preparing this Standard for
    Certification. The most important of these are IMO's circular
    MSC/Circ.860 and EN 12079. In 1991 the European Commit-
    tee for Standardisation, CEN, started developing a European
    Standard (EN) on offshore containers. Technical committee
    CEN TC 280 prepared EN 12079, which was issued in 1999,
    and a revised edition will be issued in 2006. The requirements
    for design, testing and production of offshore containers in EN
    12079 are directly based on DNV Standard for Certification
    2.7-1. The relationship between this Standard for Certification
    and other standards, codes and regulations is outlined in sub-
    chapter 1.2.
    The Standard for Certification is concerned with certification
    of all types of offshore containers as transport units. The three
    typical phases of transport are: shoreside (e.g. by fork lift
    truck), by supply vessel and lifting to and from offshore instal-
    lations. The Standard for Certification includes design require-
    ments related to all three phases.
    Under conditions in which offshore containers are often trans-
    ported and handled, the "normal" rate of wear and tear is high,
    and damage necessitating repair will occur. However, contain-
    ers designed and certified according to this Standard for Certi-
    fication should have sufficient strength to withstand the
    normal forces encountered in offshore operations, and not suf-
    fer complete failure even if subject to more extreme loads.
    The most important changes are:
