Geoportal alternatives to Esri and ArcGIS, by archetype – open-source, commercial and cloud – and why the lock-in that bites is your data, not the licence.
Surveying free spans on subsea pipelines: almost any method gives the span length, but the gap beneath the pipe – the number VIV fatigue turns on – is the hard part.
Cellula and DRDC's 385-hour Envoy AUV run signals a shift. We analyse what changes in survey planning when your platform stays submerged for weeks.
The common operating picture in offshore crisis response runs on geomatics, not "a map layer" – and operators who overlook it carry a risk they cannot see.
Underwater 3D scanning is not NDT and sizes no crack. As a visualisation aid alongside NDT and UT, it adds a full-field view of a subsea weld repair – with honest limits.
TGS's Equatorial Guinea MegaSurvey hinges on reconciling decades of legacy positioning. We unpack the geodetic control behind a 'harmonised' regional dataset.
Two subsea contractors on a third party's vessel, each contracted only to the operator and to no one else aboard. The gap left by the missing contract between them – and the machinery that has to fill it before anyone gets in the water.
GNSS jamming and spoofing are now persistent in conflict zones from the Baltic to Hormuz. We analyse the failure mode and how offshore operators harden positioning.
GNSS-INS for subsea: how IMU grade, gyrocompassing and DVL/USBL aiding decide ROV and AUV positioning against IHO S-44 survey orders.
How operators qualify, contract and manage integrated subsea contractors: single-integrator vs multi-vendor, IMCA/IOGP gates and build-vs-buy for resident ROV.
