Non Destructive Testing

Leask Marine are qualified to perform Non Destructive Testing (NDT) of structures or plant.

The Leask Marine team undertake Magnetic Penetration Inspection (MPI) of welds. These inspections can be accomplished either in water, subsea or on dry land.

We are regularly inspecting clients:

  • Pad eyes and lift points on structures
  • Sea fastenings
  • Hull repairs
  • General welding works

Subsea Flaw detection using Ultrasonic testing

Leask Marine perform UT by using a lightweight, portable hand held device which records thicknesses. Data is downloaded to a computer once on shore.

We are regularly inspecting clients:

  • Hull thickness
  • Sheet pile condition
  • Welds

Visual inspection

Our experienced team can also carry out a range of visual inspections prior to any of the above works that can quickly pinpoint problem areas which will then be further investigated, including:

  • Sheet pile condition
  • Concrete pier condition
  • Weld condition and integrity

Case Studies

  • Open-Hydro

    Leask Marine has been contracted annually to check the welding on the supporting piles of the Open Hydro tidal test platform in the Falls of Warness, Orkney.

    These welds are examined and tested from the seabed to the surface by Leask Marine qualified personnel. The welds are all cleaned by the Leask Marine commercial diving team during the slack water period between tides. The welds are tested for any flaws using an underwater Ultrasonic testing kit connected to the surface where a UT engineer reads the results and reports on the weld condition.

    Leask Marine regularly performs Magnetic Penetration Inspection of welds, both on repairs and for vessels seafastening.

    Examples shown are for storm damaged, temporary repairs to ensure a vessel was seaworthy for normal operations. The welded repairs were MPI’d by Leask Marine engineers and signed off.

    The gusset plate in the example is for seafastenings being tested by Leask Marine engineers using MPI. This was for a temporary winch that was required onboard a Subsea 7 vessel for operation.
