Case Study: National Grid Asset Inspection

High resolution photography offers unparalleled detail.

The Port of London Authority was commissioned by the National Grid Grain LNG as the principle contractor for the 2018 inspection and condition survey. the charted engineering company Marmus were subcontracted by the PLA to specify and direct inspection works.

Our high resolution photography allowed engineers unparalleled detail in reviewing hard-to-access structures. All photography is geo-tagged and mapped to fully secure google earth/GIS format -- giving engineers full high-res access for remote assessment.

High resolution paroramic photographic assets of key sections were also supplied -- enabling quick previews of potentially troublesome areas. In addition, we provided the client with 4K video to show each jetty in context.

Diving works were undertaken by SeaLift and Marine plant provision, with support for all afloat operations by Whitstable Matine, both of which are experienced National Grid contractors.

A full ultrasonic thickness survey of 25% of piles both above and below the water level was undertaken and logged. The data and high resolution imagery was analysed against design and previous inspection data by Marmus to inform final asset condition reporting.

The combined data collection offers unprecedented ease of assessment for all stakeholders, from surveyor to engineer.
