THEME: ADVANCES IN PIPELINE TECHNOLOGY & DESIGN

PROGRAMME:

The evening will focus on the following topics:

1. HPHT Deepwater Pipeline Design Using 3D FEA on a Fast Track Project
by Matt Davis, SEA Global

Subsea pipeline design has traditionally used simplified, discrete finite element models to characterise the in-place mechanical response to load effects such as temperature, pressure and geohazards. This often necessitates assumptions or simplifications with respect to the actual mechanical response of a subsea pipeline system. Specifically, the use of 3D seabeds has typically been out of reach for effective use in project design.

A combination of automated engineering workflows and relational databasing have been used to overcome these traditional limitations, by enabling submarine pipeline design in FEA to be performed on 3D seabeds, at scale and on reduced timeframes. For projects with challenging seabeds, global buckling, walking and geohazards, this methodology provides a pathway for efficient engineering solutions.

The presentation will share the engineering solutions for a project that recently completed Detailed Design, demonstrating the success of this modernised approach to submarine pipeline design.

2. Qualification of Large Diameter Seamless Pipe Manufacture for Buckle Arrestors
by Stuart Folkard, Wood

Buckle arrestors used in subsea pipelines are generally fabricated from thicker walled pipe than is used for the rest of the pipeline. The heavier pipe thickness is often at or exceeds the manufacturing limit of traditional LSAW pipe making processes such as JCOE or UOE, leaving the only options as being three-roll press forming or forging. A recent project considered seamless pipe manufacture for the large diameter, heavy wall thickness buckle arrestor pipe required. The seamless manufacturing route had advantages of cost and delivery schedule over the alternative method of forging.
This presentation describes the qualification undertaken to confirm the suitability of the seamless manufacturing process for production of pipe for buckle arrestors.
