Low Carbon Emission Solution for Pipeline Purging

December 2017, Vol. 244, No. 12

DNV GL won first place in a competition organized by GRTgaz, the French natural gas transmission system operator, which runs a series of challenges during the year to identify innovative concepts to optimize its operations. The winning solution is aimed at reducing the carbon emissions associated with pipeline maintenance activities. The specific objective of this challenge, which is part of GRTgaz’s Open Innovation program, was to provide a solution to reduce the environmental footprint of network maintenance activities for GRTgaz, requiring the evacuation of pipes while avoiding or minimizing burning or venting of trapped gas....

Inline Isolation Provides Decommissioning Benefits

November 2017, Vol. 244, No. 11

When a multinational energy services company planned to decommission an onshore gas terminal in northwest England, it needed a fast, total solution that would avoid depressurizing and blowing down a 25-mile (40-km), 36-inch pipeline. The pipeline runs from an offshore field through north and south sub-terminals prior to feeding into the United Kingdom’s gas transmission network. A key concern was to complete the line decommissioning safely and quickly to minimize potential disruptions to the supply schedule. The solution was the proprietary SmartPlug® inline isolation tool from T.D. Williamson (TDW). The tool is a remotely controlled,...

Pipeline Monitoring Systems to See Good Times Ahead

November 2017, Vol. 244, No. 11

A growing number of oil and gas leaks in production, pipelines and storage tanks due to natural disasters, and stringent government regulations for pipeline safety and security will drive expansion and upgrades of pipeline monitoring systems in the future. In the coming years, the market is expected to witness the highest growth rate in the Asia-Pacific region. This can be attributed to the large population in these countries, along with new pipeline construction, which will increase the demand for pipeline-monitoring systems. Pipeline monitoring system segments: Technology: This area is broken down into ultrasonic, pigging, smart...

Ditch Witch, Utilicor Technologies Partner Up

October 2017, Vol. 244, No. 10

Public works managers across the nation have welcomed the use of keyhole coring: a less-costly, safer and less-disruptive approach to underground roadway and sidewalk utility repairs than traditional, large excavation techniques. Last month Ditch Witch®, a Charles Machine Works Company, announced its partnership with Utilicor Technologies, Inc. to bring the benefits of advanced keyhole technology and reinstatement to contractors, municipalities and utilities globally. Utility contractors need not bring heavy and physically demanding equipment such as jackhammers and backhoes for every utility maintenance project that requires asphalt or concrete repairs. Instead, they can operate a nimble, […]

Midstream Company Solves Flow Measurement Issues

October 2017, Vol. 244, No. 10

When Mike Heckl was a director of operations for Crestwood Midstream, the company established itself in the West Virginia Appalachian Basin by purchasing an area of development from a major upstream firm with a large acreage in the Ohio and West Virginia Marcellus/Utica Shale fields. They had already installed about 45 miles of pipe at this location with several dozen well pads flowing natural gas. They were not a midstream company, so Crestwood purchased the right to transport the gas for that particular area. Limited Measurement Available The upstream company had built this pipeline knowing...

Verifying Worker Training Onsite to Boost Safety

October 2017, Vol. 244, No. 10

Pipeline and energy companies are safety-conscious for good reason. Fewer accidents mean fewer delays, higher worker morale, lower insurance costs and avoidance of OSHA fines. Ensuring that workers do only jobs they’re trained for is one of the most critical steps in a safety program. An untrained worker who botches a job may injure himself and others, damage expensive equipment, cause fires and release hazardous materials. But in the rush to get things done, proper vetting can get overlooked. How can supervisors in the field know for sure about whether a particular worker is qualified […]

Excavators Look to Doosan for Challenging TAP Project

September 2017, Vol. 244, No. 9

A year into the project, 52 new Doosan excavators are working on a section of the Trans Adriatic Pipeline (TAP), involving the construction of about 225 miles (360 km) of pipeline in Greece. In March 2016, a new company formed by Bonatti S.p.A. and J&P-Avax Group was awarded the engineering, procurement and construction (EP&C) contract for this section of the TAP Project. Following a competitive analysis of eight leading excavator manufacturers, Bonatti-J&P Avax chose Doosan equipment to handle the 48-inch pipes. The construction work required in the TAP project presented many challenges, leading up to the...

DNV GL Updates RP for Free-Spanning Pipelines

August 2017, Vol. 244, No. 8

Offshore pipeline spans, due to uneven seabed or seabed erosion processes, can require huge and costly seabed interventions. The DNV GL recommended practice (RP) on free-spanning pipelines has been widely applied in industry to solve the problems related to free spans in pipeline design and operation. The RP has now been updated with project and research experience from the last decade on free-span dynamic response, particularly on structural modeling. DNVGL-RP-F105 enables significant costs savings, both in the newbuilding and operational phase. The scope of the RP is to provide rational design criteria and guidance for...
