On Hire and Off Hire Condition Surveys in UAE Explained
A charter is a handover of a very expensive asset between two parties who will not see each other again until something goes wrong. An on hire condition survey and its matching off hire survey exist to record exactly what changed while the charterer had the vessel, and both draw…

Marine Warranty Survey in UAE: What Underwriters Require
A Global Map Survey's marine division is not a quality inspection. It is a condition of insurance. An independent surveyor appointed on behalf of underwriters reviews a marine operation before it happens, and issues a certificate of approval without which cover for that operation does not attach. This article explains…

Offshore Site Investigation in Abu Dhabi: Survey Scope
An offshore site investigation in Abu Dhabi usually goes wrong in the same way. The geotechnical programme is mobilised before the geophysics, boreholes land in the wrong place, and the campaign returns to sea at full day rate to fill the gaps. Ground investigation sequencing is the whole discipline. This…

Magnetometer Surveys in UAE: Finding Buried Ferrous Targets
Sonar sees what sits on the seabed. It cannot see a pipeline buried under two metres of sand or a shell that settled into the mud decades ago. A Global Map Survey's magnetron meter survey page finds those targets by measuring distortions in the earth magnetic field caused by ferrous…

Side Scan Sonar Survey in UAE: Imaging the Seabed Surface
A Global Map Survey's side scan SONAR surveys and mosaicing page produces something closer to an aerial photograph of the seabed than to a depth chart. It shows texture, debris, scour, exposed pipelines and anything else sitting proud of the bed, across a wide swath either side of the tow…

Sub Bottom Profiling Survey in UAE: Seeing Beneath the Seabed
Bathymetry tells you where the seabed is. It says nothing about what lies underneath it. A Global Map Survey's sub-bottom profiling and magnetometer surveys page fills that gap, imaging the sediment layers below the bed so that dredging, piling and cable burial can be planned against real ground rather than…

Bathymetric Survey in UAE: Singlebeam or Multibeam
Most tenders for a Global Map Survey's multibeam and singlebeam bathymetric surveys page name a sensor before they name a requirement. That is the wrong way round. Singlebeam and multibeam answer different questions at different prices, and choosing between them is a decision about coverage and consequence rather than about…

Settlement Monitoring Survey in UAE: The Complete Owner Guide
Ground moves. Every structure in the Emirates settles a little as load arrives, as neighbouring excavations relieve stress, and as groundwater levels shift. A Global Map Survey's monitoring division measures that movement precisely enough to tell a harmless bedding in from the early signature of a problem. This guide explains…

Settlement Monitoring Survey Abu Dhabi: Choosing a Contractor
Monitoring quotes are unusually hard to compare. Two providers can price the same settlement monitoring survey in Abu Dhabi with a large gap between them, and the difference is rarely visible in the scope wording. It normally sits in the reference network, the accuracy actually achieved and who does the…

Structural Assessment Services in UAE: The Survey Evidence Behind the Verdict
A structural assessment reaches a conclusion about whether a structure is fit for its purpose. That conclusion is only as good as the measurements underneath it. Structural assessment services in UAE depend on survey data that establishes what the structure actually is, how it has moved and what condition it…
