Tittel

Knowledge basis for repair contingency of pipelines - ROP

Populærvitenskapelig sammendrag

Steel pipelines represent today the most important infrastructure for transport of oil and gas to

onshore facilities in Norway and Europe. Both clad and lined pipes, including pipe-in-pipe, have

already been installed (Stjerne-8.8" pipe, Tordis-9.4", Visund North-10", all clad pipes installed last

year; while Tyrihans-16/18" and Aasta Hansteen-12" are lined pipes). Today, there is no repair

contingency available for this kind of pipelines, and relevant knowledge must be built, as described

in the research tasks of the present proposal. In parallel, the TTA 4 strategy highlights the technology

gap concerning degradation ("Integrity management and risk reduction") with R&D priority

addressing the understanding and assessing of degradation mechanisms (including modelling). This

is also an important part of the present project. It is recognised that the infrastructure is aging, and

also that enhanced lifetime of existing oil and gas fields is targeted. For newly discovered fields,

transport is provided by coupling of new pipes with existing pipeline infrastructure, which means

that existing pipelines may face internal flow of constituents they were never designed for, such as

hydrogen sulfide or carbon dioxide. In order to maintain Norwegian industry's position in the

technology front in the TTA 4 area, it is essential with a continuous national emphasis on R&D. To

establish knowledge basis for weld repair of both existing and new pipelines, as well as their

degradation behaviour is deemed necessary for:

- Integrity management and risk reduction

- Enhanced lifetime of existing infrastructure

- New fields in environmentally sensitive areas

- Aging infrastructure

The project structure consists of the following 4 workpackages (WPs): (WP1) Structural integrity,

(WP2) Material and process modelling, (WP3) Technical solutions, and (WP4) Demonstrators.

The project will address education of 2 PhDs, one related to the weld repair process and one within

structural integrity.
