Consultancy services have been provided to Kellogg Brown and Root (Dolphin Energy pipeline and BP Plutonio), JPKenny-Ionik Consulting (marketing and technical study reports), Aker-Kvaerner (tree valve materials), Granherne (AGIP-KCO Kashagan pipeline materials, Saipem UK (Dolphin flanges, Nexen Buzzard flexibles, Statoil SRI 13Cr spools) and InteTech for Technip (project management team for AGIP NC41 subsea development).

 Materials Selection and Corrosion Engineering

The Materials and Corrosion Consultant provides a comprehensive materials selection service for any stages of a project. Materials selection encompasses:-

·         selecting materials of construction, based upon the service requirements and cost, from the most straightforward to sophisticated alloys and high strength materials, including Aluminium and non-ferrous alloys, plastics, resin based composites, elastomers, timber, etc.

·         assessing corrosion rates and defining the requirements for inhibition, internal cathodic protection (CP) or corrosion resistant alloys

·         specifying speciality treatment and corrosion inhibition chemicals and defining the requirements for internal corrosion monitoring systems

·         reviewing the need for special materials resistant to warm or hot seawater, Hydrogen sulphide, or other fluids and corrosive agents capable of causing crevice, pitting or stress corrosion cracking

·         ensuring compatibility of materials with cathodic protection and other Hydrogen evolution processes

·         addressing low or high temperature materials requirements and relevant testing

·         selecting coatings (including erosion, insulation and fire protection) in conjunction with the CP associate as appropriate

·         advising on operational materials risks and risk management

Welding Engineering and Fabrication

The Welding and Fabrication Consultant's role includes:-

    input to the design and construction of offshore structures, pipelines and chemical plants from preliminary design through to support of the construction site team.
    advice during design on the weldability of materials, welding design, fracture toughness design criteria and the extent of post-weld heat treatment.
    development of material and fabrication specifications
    conducting technical bid assessments of manufacturers and fabricators.
    technical audits of vendors or fabricators
    review of vendors' or contractors' welding, fabrication and non-destructive testing documents
    assignment to fabrication, construction and installation sites to co-ordinate fabrication activities.
    assessment of failures and rectification and prevention strategies.

Cathodic Protection and CP Monitoring

Where required, the Consultancy will call in a Cathodic Protection associate, who designs and assesses cathodic protection systems including:-

    cathodic protection systems for subsea systems, offshore pipelines, offshore structures and onshore pipelines and tanks and terminals
    ensuring that compatible coatings are used
    specifying and checking coatings before during and after application
    selecting, specifying and checking cathodic protection monitoring systems and site surveys (CIPS, DVCG, routine testing)
    supervising and checking the installation and commissioning of such systems.
    advising on induced a.c. effects of pipelines co-located with overhead power transmission lines and creating a computer model of same for mitigation design purposes
    advising on d.c. interaction with traction systems and neighbouring CP system
