This is an exciting and challenging time for the oil and gas market. Stable oil prices and technical advancements are enabling energy companies to invest in a diverse range of energy fields from shale and oil sands to offshore fields in water depths exceeding 1500 meters. Developing these fields involves a wide range of technical challenges for the industry.The EWI Strategic Technology Committee for Oil & Gas is an industry-based group that works to identify gaps between current technologies and industry requirements. The committee was founded to advance the state of materials joining and allied technologies within the industry, and to assist in modernizing industry standards.
This program will conclude in the fall 2014 and is focused on identifying the optimum welding parameters for submerged arc weld (SAW) and flux-cored arc weld (FCAW) consumables having strength levels of 70 and 80 ksi. Higher strength plate steels are of increasing interest for use in offshore fabrication but most fabricators have limited experience with these higher strength grades. This project will characterize the effect of welding heat input on weld mechanical properties to assess best practice for use in offshore fabrication yards to ensure adequate strength and toughness can be achieved.
This program will enhance the safety and structural integrity of offshore welded structures for arctic service by fully characterizing the fracture toughness and tensile strength properties of submerged arc weld (SAW) and flux-cored arc weld (FCAW) consumables at temperatures down to -60oC as a function of welding parameters such as welding heat input and interpass temperatures. In addition, alternative welding techniques that may enhance weld fracture toughness will be evaluated. This program will kick-off in summer.
EWI launched the Strategic Technology Committee for Oil & Gas in the spring of 2013 with six members. Over the last year the membership base has continued to grow. Current STC members include:
EWI STC members are invited to participate in spring and fall member meetings in which STC project results are shared and reviewed. New projects are identified and selected at member meetings as well. Members are also encouraged to participate in project work groups which give guidance and direction during the execution of projects.
In addition to participation, STC members have exclusive access to written results of current and previous STC projects through the member’s only webpage.
