CRC-Evans has provided equipment and services for over 80,000 square kilometres of pipelines in more than 100 countries, including the most extreme conditions and difficult terrains. It is a market leader in each of its core businesses and with regional capabilities around the world, providing operators with one of the most extensive support structures in the industry. Its onshore and offshore companies are established, financially solid and known for their commitment to production success.

 

Onshore : 

Bundled Pipeline Construction Solutions

The selection of CRC-Evans, a Stanley Oil & Gas Company, comes as no surprise to people in the pipe welding business.   The use of CRC automated pipe welding systems has a long and successful history. It is not just the welding of the pipe, however, that influenced the selection of CRC-Evans methodology; it was the bundled solutions concept, which promises higher efficiencies, increased productivity, onsite technical support and higher finished weld quality, that impresses its customers.  The CRC-Evans bundled pipeline construction solution concept includes providing: 

  • The automated welding systems
  • Pipe Facing Machines (PFM) for welding joint preparation.
  • The pipe bending equipment to allow for changes in grade and terrain types: marshland, under roads, rivers, and railroad tracks.
  • The field joint coating system using CRC-Evans’ Fully Automated Spray Technology (F.A.S.T.) system and a multi-component liquid (MCL) epoxy for all field girth welds. 
  • Provide onsite technical support for all of the CRC-Evans for pipeline projects.

The acceptance criteria used to define the selection of the joining systems and other equipment loom large enough, but the most important product CRC-Evans will provide to the project is the onsite technical support. 

 

CRC-Evans Centurion Pipe Bending Machines

CRC-Evans has made a study of the needs of pipeline construction contractors and it invests heavily in the research and development of its equipment offerings.  In the case of meeting, and exceeding, pipe bending requirements it has  developed the newer Centurion Pipe Bending machinery.  The systems are available in three distinct pipe diameter ranges: 6.0 – 20.0”, 16.0 – 30.0” and 22.0 – 36.0”.  The development work completed by CRC assures that the Centurion easily handles the use of higher yield pipe.  To date the Centurion Pipe Bending systems provide an 80 per cent improvement in cylinder travel speed and 30 per cent more bending power than competitive machinery.   The benefit is faster and more robust bending operations that will reduce time and cost for meeting required completion time.

 

Automated Pipe Welding and Welding Process

CRC-Evans is world renown for its automated welding systems.  This is true for the IWM GMAW system  dual torch external GMAW system.  The internal root bead is made with GMAW-S. The external welds include a hot pass completed using GMAW-S and external fill and cap passes employ the use of GMAW-P.  The pipe is always positioned 5G and all of the mainline welding completed in the 5G vertical down welding position.

 

Quality Assurance Welding Accountability Measures

Each of the automated welding systems has digitally controlled user interface.  The interface allows the system to control for the welding procedure/travel speed and other variables.  The user interface provides control and preset limits for each welding variable and as a result assures consistent welding parameters for all of the weld joints.  Furthering the idea of finished weld consistency, The CRC systems provides welding procedure security through onboard data acquisition.  Each weld made, then, has a welding procedure software file. The data provides for a level of quality assurance associated with each weld or set of welds not often available in similar projects.  Quality assurance via data acquisition is an extremely important share of the CRC Bundled Solutions concept and it is in keeping with the expectations of its customers

 

Corrosion Resistant Field Joint Coatings: F.A.S.T. and MCL

Pipeline contractors ready the finished welds for coating by shot blasting the weld joint and adjacent areas.  The blasting provides an anchoring surface for the corrosion resistant coating.  The coating is applied then to the prepared area using the CRC developed fully automated spray system (F.A.S.T.).  The newer CRC method assures uniformity in the thickness of the multi-component liquid (MCL) – the MCL system consists of two components: the hardener and the base – and the spray width.  Moreover, the development of this newer system minimized overspray and any potential hazard to the environment and the operator.  The system is capable of coating up to fifteen joints per hour.  Repeatability in terms of coating thickness provides optimum material usage and lower overall costs.

 

Offshore:

CRC-Evans gained 100 per cent ownership of its offshore division in 2010, pairing an experienced offshore contracting team with CRC-Evans’ proven product portfolio and leadership in the pipeline industry. Today, in addition to offering the world's most advanced offshore pipeline construction technology, CRC-Evans offers the expertise of a highly experienced team of offshore and spoolbase specialists trained to directly support automatic welding, inspection and specialist field joint coating operations, as well as a full staff of offshore-qualified management to lead this dedicated team. These are people who truly understand offshore—people who listen and communicate intelligently with you about your very specific project needs. Just in the past five years, CRC-Evans Offshore has been involved in projects from Brazil to Norway to Egypt ranging from mobilizing a temporary spoolbase in Cyprus, to the welding of CRA-clad materials and application of the latest field joint coating systems developed in-house to meet the latest deep water specifications.

CRC-Evans has engineered its offshore pipeline construction technologies to address the enormous logistical and financial challenges that come with offshore operations. Among the many automatic welding innovations are tandem-wire and dual-torch technologies for faster welding, through-the-arc tracking for more accurate welds and digital-to-digital programming, onboard data collection, laser inspection and touch-screen control to reduce errors and downtime. Light, ergonomic equipment designs allow easier handling in limited spaces.

Pipeline Induction Heat Ltd., the specialist field joint coating division of CRC-Evans, has an extensive track record in the offshore and spoolbase industry throughout the world with all of the major offshore contractors. Application systems and procedures have been developed to meet the changing requirements from within the industry with the emphasis on HSE, production and cost. In addition to our patented Fused 3-layer PP and PE processes, more recent developments have included IMPP and Neptune, as well as technological advances with various fully automated processes.

CRC-Evans inspection group is known as Stanley Inspection and is a market-leading asset integrity services provider to the global energy industry.  Service offerings include Automated Ultrasonic Testing (AUT), radiography and many other inspection methods for pipelines, petrochemical plants and industrial facilities.  Now, with one company integrating your welding, inspection and coating services, we make the job easier for you.  One supplier instead of three means quality work, faster development, smoother production and better customer service.

In the past few years, CRC-Evans Offshore has also focused on strategic partnerships to be able to offer clients even more value for their investment. When CRC-Evans enters into an agreement with another company, the idea is to work together in a way that goes beyond just being partners to a contract. CRC-Evans wants to bring in its individual expertise and knowledge to fill in any gaps so both companies can help solve each other’s problems. These partnerships provide customers with a value-add that they wouldn’t be able to get from another single provider.
