Gasunie experiences minimal lost time accidents and serious incidents. The consequence, however, is that these very limited events generate limited data for use in in-depth analyses for preventive measures. Gasunie registers all accidents, incidents, and dangerous situation, and the record shows whether the event is a potentially serious event (PSE). To learn from unwanted or dangerous situations it is useful to analyze PSE. These are events that could have led to (more) serious consequences in just slightly different circumstances in another credible scenario. A discussion covers useful results that can be obtained from quantitative and qualitative information from this type of PSE and whether this information be used for preventive action and for generating performance indicators.

In the Netherlands a 485 km (300 mi.), 48 inch diameter, high pressure (8 Mpa, 1200 PSI), natural gas pipeline is being constructed. A large part (> 15%) of the pipeline is constructed trenchless in which horizontal directional drillings (HDD) up till 1400 m (4600 feet) length are used. This way of constructing is not only demanding from a construction point of view but also set high demands on the quality and strength of the coating of the steel pipes that is used. For this task, dedicated mill and field joint coating systems were selected. Partly the selected coating systems are new in the industry. In the paper an overview is given of: • the different constructions used and the demands they deliver for the coating • the coating systems chosen, both mill and field coating • the quality checks involved • tests and results • experiences, conclusions and outlook for the future. ©2012 by NACE International.

Managing fugitive emissions has taken an important and effective role in Gasunie's footprint reduction program. A discussion covers Gasunie's experiences with the fugitive natural gas emissions; reduction of fugitive natural gas emissions; and the results achieved by the Leak Detection And Repair program and setting up the fugitive emission management. This is an abstract of a paper presented at the 25th World Gas Conference (Kuala Lumpur, Malaysia 6/4-8/2012). Source

Liberalization in the European gas market requires transmission system operators (TSO) to be fully independent from the commercial interests of their parent companies, leading to complete unbundling of previously integrated companies into two separate entities. One of these, the trading arm, represents the company exposed to commodity risks that are high and consequently result in high margins on natural gas trading. On the other hand, regulated gas transmission is assumed to be a less risky business, and is therefore allowed lower margins by regulators. Moreover, transmission companies are put under high pressure by the regulators to lower their costs, resulting in further lower regulated tariffs. The question is whether this short-term reduction of transmission costs is the best solution in the long run, given the objective of keeping gas prices as low as possible for consumers and industries. A discussion covers the lessons learned from the transition of an integrated company into a separate transmission company within a time frame of several years - Gas Transport Services, the transmission arm of Gasunie in the Netherlands - and how unbundling has led to considerable changes in the responsibilities and the method of working for TSO.
