Uxo Management

We create the most cost-efficient practice for the industry-wide management of unexploded ordnance (UXO) detection, identification, clearance and removal.

Global developers of offshore energy infrastructure projects are often faced with the unanticipated challenge of UXO in their proposed projects - a substantial risk legacy of Wars and years of munition dumping on the seabed. 

UXO detection

Survey, Identification and Removal of UXO objects

We investigate and map potential targets with hi-res sonar, ROV or divers, and remove any confirmed UXO objects through an Explosive Ordnance Disposal (EOD) process. These operations are carried out offshore and near shore. We have the expertise and the experience to perform UXO management according to Dutch, German and English law.

UXO management is defined as three distinct activities:

  • geophysical survey to identify non-UXO and potential UXO objects
  • visual inspection to positively identify non-UXO or actual UXO objects
  • disposal as required of both non-UXO and actual UXO objects
