APPLICATION 31 · WATER, WASTEWATER & DESALINATION

Intake and outfall structures

Condition surveys for marine-facing pipelines, structures and components exposed to seawater, flow effects and environmental deterioration. Within water production, treatment, transmission and discharge infrastructure exposed to saline and chemically aggressive service, this asset can directly influence leak prevention, corrosion management, structural condition and dependable public or industrial service. A focused integrity programme should therefore connect the design basis, materials, service history, previous findings and current operating condition, so that inspection effort is directed to credible damage locations and produces information that supports practical maintenance decisions.

Integrity Focus

Principal considerations and IAIS UAE support

Principal integrity considerations

  • Section loss, pitting and coating breakdown in exposed or water-trapping areas.
  • Fatigue or weld cracking at connections, nodes, attachments and load-transfer details.
  • Deformation, impact damage, loosened fasteners, foundation movement and local overstress.

How IAIS UAE may support

  • Review drawings, loads, modifications and previous findings to identify critical members and connections.
  • Perform close visual examination, dimensional surveys, thickness measurement, weld NDT and difficult-access inspection where justified.
  • Record severity and location systematically and provide evidence for engineering review, repair design and maintenance planning.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

Structural condition report, member and connection register, annotated photographs, dimensional/thickness data and prioritised actions.

Codes & standards

The activity may be planned and reported against the applicable provisions of AWWA, ASME B31 series, API tank standards where applicable, ISO, ASTM, EN, BS and authority/client requirements. Final references and acceptance criteria remain subject to approved project and statutory requirements.
