Recent pipeline repair tooling developments

Abstract

Recent events in Australia have focussed attention on the area of pipeline repair. This is historically a largely overlooked discipline, however, the results of failing to make adequate preparation may be significant. A number of tooling systems have been developed that provide intervention capability for the event of pipeline damage. In particular, several pipeline clamp designs have been developed for both high and low pressure applications, in addition to other intervention equipment. This has been supplemented by in-field experience of several of these systems. Additionally, a unique mechanical pipeline connection system for clad and lined pipes is now undergoing development.

There are a number of issues concerning pipeline repair that are particular to Australian waters including: remoteness from the main marine centres, vessel and equipment mobilisation, metocean conditions and the nature of the local pipeline infrastructure.

This presentation reviews the above concerns in light of pipeline repair philosophies and discusses the innovative technology that is being developed to assist in meeting the local challenges.
