This standard applies for transport related requirements for offshore containers with respect to design, manufacture, testing, certification, marking and periodic inspection.

The standard covers the container structure and any permanent equipment for handling, filling, emptying, refrigerating, heating and safety purposes.

The intention is that offshore containers shall meet the following requirements:

Be safe in use with regard to:

— lives

— environment

— hazard to the vessel/installation.

Be suitable for repeated use through choice of:

— material

— protection

— ease of repair and maintenance.

The requirements in this standard are based on a number of assumptions regarding the handling and operation of offshore containers:

— They are lifted individually by crane hook attached to top link of lifting set.

— They are not lifted by spreaders or using ISO container fittings.

— They can be lifted anywhere (worldwide) by any crane with sufficient capacity and speed.

— For containers only approved for limited operation area (temperate climate) see App.J.

— They are only stacked if they are designed for this.

— They are stacked only onshore or on offshore installations. Not to be stacked during transport on ships.

— Cargo or loose installations are properly secured in the container.

— The container is designed to give adequate protection to its cargo or to installations inside.

— They are handled according to IMO’s Code of safe practice for supply vessels.

— Handling and operation is in accordance with local regulations.

DNV GL may approve alternative solutions that are found to represent an overall safety standard equivalent to the requirements in this standard. Such approval may be revoked if subsequent information indicates that the chosen alternative is not satisfactory.

When the word container is used throughout the standard, it means an offshore container.

Use of the word shall implies a mandatory requirement when seeking the approval of DNV GL. Use of the word should implies a recommended approach, where comparable solution may also be acceptable.

The terms DNV 2.7-1 or 2.7-1 are generally used as short terms for DNV Standard for certification No. 2.7-1 and DNVGL-ST-E271.

The passages throughout this standard marked Guidance Note and Note are not to be taken as requirements by DNV GL. Guidance notes are intended as practical advice or recommendations for the designer, manufacturer or operator, while notes provide information.

This standard often refers directly to various standards (EN, ISO etc.), or to other recognised standard. Recognised standard means a standard found acceptable by DNV GL.
