Pipelines, Flowlines & Risers
Pipelines, flow lines and risers contain the hot, pressurised oil and gas piped up from seabed installations to shore and for processing. GL Noble Denton’s pipeline engineers provide knowledge and experience of design codes and ensure that this valuable cargo arrives safely.
Offshore and Subsea Pipelines
Subsea pipelines present very different engineering challenges as faced by onshore lines. They must deal with higher external pressures and colder temperatures, and unless buried or trenched in the seabed, subsea pipelines are subject to currents and tidal movements.
In addition to providing pipeline services through all project stages – from conception to operation to decommissioning – we add value to our clients’ projects and assets by ensuring that client and regulatory requirements are met.
Our expertise helps covers upstream, in-field gathering and export systems for high-pressure transmission trunk lines through to low-pressure downstream distribution systems. This knowledge extends to issues including choice of a pipeline route, materials (we understand the problems caused by fluids carried within pipelines) to laying technique. Whether installed above or below ground, GL Noble Denton experts ensure client and regulatory requirements are met.
GL Noble Denton offers design appraisal, certification and classification of structures of all types (steel, concrete, fixed, floating) and a full range of subsea pipeline, flow line and riser design consultancy services including:
To ensure projects remain on track and budget during the manufacturing / fabrication phase, GL Noble Denton provides comprehensive project support services including:
GL Noble Denton’s engineering expertise and our practical marine operations experience allows us to lead the way in pipeline, flow line, and riser installation in both shallow and deep water.
Reliability of subsea pipelines and risers is key to the success of any field, making integrity management extremely important. While attention is paid to extending operating life, preserving adequate safeguards for human life and the environment is of overriding importance.
Pipeline Integrity Management
Pipeline integrity management services help preserve and improve their performance in the most economical manner, whilst complying with safety and environmental regulations.
Pipeline Inspection and Testing Services
Oil and gas pipelines are capable of carrying high-temperature, high-pressure crude oil to freezing, liquefied natural gas. Pipes are vulnerable to attack by internal and external corrosion, cracking, third-party damage and manufacturing flaws. Our resources include:
Spadeadam Test Site, UK
The Spadeadam Test Site is a world-class test facility where full-scale destructive and non-destructive experiments can be fulfilled, discreetly and with complete confidentiality.
Pipeline Software Tools
GL Noble Denton offers Pipeline Software Tools like SynerGEE® Gas for Network Modelling and Analysis, Pipeline Simulator (SPS) for flow simulation, GALIOM the Asset Integrity Management (AIM) software tool and UPTIME combining decision support tools with a data management system.
