Pipelines

Fitness-for-Service (FFS) is an assessment that is carried out using standardized methods and criteria, that evaluates the structural integrity of an asset/component to determine whether the asset/component is suitable for its intended use.

The Fitness-for-Service (FFS) assessment provides a quantitative measure of structural integrity and is part of asset integrity management. The assessments are used to highlight the need for replacement or repair of assets/components.

Two of the most commonly used are the recommended practice for assessing fitness-for-service published by the American Petroleum Institute (API) in API 579 and the guidance for the assessment of defects metallic structures published by British Standards in BS 7910.

2019

This British Standard gives guidance and recommendations for assessing the acceptability of flaws in all types of structures and components. Although emphasis is placed on welded fabrications in ferritic and austenitic steels and aluminium alloys, the procedures can be used for analyzing flaws in structures made from other metallic materials and in non-welded components or structures. The methods described are applicable at the design, fabrication and operational phases of the life of a structure.

Finite Element Analysis of the In-service-Welding of T Joint Pipe Connection

2010

In this paper the effects of two major parameters (a) main pipe thickness; and (b) the amount of heat input (electrode diameter) have been investigated on the burn-through risks during the in-service welding of an AISI-316 pipe branch connection on a steam pipeline at full line pressure to perform hot tapping.

A 3D Finite Element (FE) based thermo-mechanical analysis has been carried out to model the in-service welding. To assess the burn-through risks, current recommendations only rely on the observation of the main pipe inner wall surface temperature. However, this criterion does not take into account the effect of mechanical stresses due to the inline pressure.

In this study, the thermomechanical stresses and temperature distribution along the main-pipe wall-thickness have been obtained and values of the effective stress have been compared against the temperature dependent yield stress of the material.

Penspen - Can the Pre-Service Hydrotest be Eliminated

2000

This paper approaches the hydrotest from the structural point of view and asks some fundamental questions:

·  Why was the hydrotest developed?

·  What are the advantages and disadvantages?

·  What are the benefits, perceived or quantifiable?

·  Have hydrotest failures occurred with regularity?

·  Have manufacturing, transportation, and construction methods changed to negate the need for a hydrotest?

·  Are there alternative approaches that can be used to replace the hydrotest without any loss in benefit?

The paper concludes that, technically, the pre-service hydrotest can be replaced but activities need to be put in place to compensate for all benefits accrued as a result of conducting the test.
