Strategic Technology Committee for Oil and Gas
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.
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.
The committee’s role is to provide funding, industry insight, and technical guidance during the execution and development of STC projects.
Committee members are typically technical leaders within their organization in the areas of materials joining and/or allied technologies. Member organizations are encouraged to have participation from multiple technical staff as appropriate (i.e., experts in NDE, welding, structural integrity, materials testing, etc.).
The EWI Oil & Gas Strategic Technology Committee consists of senior technical experts from the major oil & gas operators, fabricators, material and welding consumable suppliers and engineering companies within the industry. STC projects center around pre-competitive technologies in the areas of welding, materials joining and allied technologies such as non-destructive examination, materials testing, and structural integrity.
ASSESSMENT OF THE WELDABILITY OF HIGH STRENGTH STEEL PLATE
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.
CHARACTERIZATION OF WELDING CONSUMABLES FOR ARCTIC SERVICE
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:
- Nippon Sumitomo Special Metal
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.
