PD 8010-2:2015+A1:2016 - Page 5

Pipeline systems. Subsea pipelines. Code of practice | Status: Confirmed, Current

1 Scope This part of PD 8010 gives recommendations for and guidance on the design, selection, specification and use of materials, construction, installation, testing, commissioning, operation, maintenance and abandonment of steel subsea pipelines in offshore, nearshore and landfall environments. Guidance on the use of flexible composite pipelines is also given. It is not intended to replace or duplicate hydraulic, mechanical or structural design manuals. This part of PD 8010 is applicable to subsea pipelines intended for the conveyance of hydrocarbon liquids, hydrocarbon gases, carbon dioxide and other gases, liquids and gases in two-phase flow, fluid-based slurries and water.

NOTE 1 Although primarily concerned with subsea pipelines associated with the oil and gas industry, PD 8010‑2 is likely to have application to a wider range of offshore activities.

The extent of pipeline systems covered by this part of PD 8010 is shown in Figure 1. This part of PD 8010 is applicable to pipelines in water depths up to 500 m.

NOTE 2 In deeper water, other international codes such as DNV-OS-F101 are applicable.

It does not cover sea outfalls (see BS EN 752) or fluid umbilicals (see BS EN ISO 13628‑5).
