Application

This standard DNVGL-ST-E273 covers suitable requirements to portable offshore units (POUs), see [1.4.3], with respect to design, manufacturing, testing and certification.

It is the intention that a POU that is certified by DNV GL according to this standard could be safely sea transported and lifted offshore including subsea (see [3.11]) anywhere in the world. Standardized frames/ skids used for sea transport only may also be certified as a POU, see [3.3.3].

This standard covers the POU’s main structure, supports for any permanent equipment and features important for the functionality during the transport phase.

The intention is that POUs shall meet the following requirements:

Be safe in use with regard to:

life

environment

hazard to the vessel/installation.

Be suitable for single or repeated use in applicable cases through choice of:

material

protection, and

ease of repair and maintenance.

It shall be noted that this standard covers only the POU design and it is the responsibility of the transport/ installation contractor to ensure that all handling is carried out safely with due consideration to applicable HSE requirements.
