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
