General

This standard provides specific guidance and recommendations for Engineered onshore, inshore and offshore lifting operations, conducted both in air and sub-sea.

Guidance note:

‘Engineered' refers to lifts that are planned, designed and performed according to requirements in DNV-OS-H101, i.e. specially prepared and documented.

Weight limitations (upper or lower bound) are not specified herein, however, requirements in other standards and local/international regulations may be relevant and governing, for objects with lower weights (typically less than 50 tonnes) and for operations involving routine lifts.

Guidance note:

‘Routine' lifts are considered ‘everyday' lifts, without specific supporting documentation; e.g. lifts associated with general cargo carrying or portable units from/to supply vessels, minor erection lifts on construction yards, etc. For such lifts higher safety factors may be applicable to compensate the lack of detailed engineering. However, routine lifts are not covered in this standard.
