Identification of explosive remnants of war along the English coast

A new high-voltage cable was laid across the North Sea; it should be installed in 2019. Martens en Van Oord contributed to this project by identifying 300 targets of potentially Explosive Remnants of War (ERW) in Ramsgate (UK). Eight objects, identified as Unexploded Ordnance (UXO), were removed and the route was cleared and completed on time. The follow-up work could then take place safely.

The new cable is part of the NEMO link project and should take care of power distribution on both sides of the North Sea. On the continental European side, in Zeebrugge, MvO carried out a similar assignment (see Zeebrugge project).

Project characteristics

  • Use of Scheldeoord: a stable dredging pontoon that is suitable for offshore operations and is equipped with a diving system and a diving ring, which allows divers to work safely in the strong coastal current.  
  • Our knowledge and equipment were used to identify explosive remnants of war.  
  • A groundbreaking assignment in the United Kingdom.  

Pontoon Scheldeoord
In mid-May 2017, the Scheldeoord departed from Moerdijk and set sail for the United Kingdom. During the UXO Survey of the seabed near Ramsgate, about 300 suspicious objects had been discovered at an earlier stage. In order to approach and identify these objects, the client Bluestream Offshore hired the Martens en Van Oord pontoon ‘Scheldeoord’, including a unique specialist diving ring, crew and tug. We used it to carry out our part of the operation: the identification of the suspicious objects. 

Professional team
The project near Ramsgate was carried out by three companies. In addition to the contribution of Martens and Van Oord, main contractor Bluestream provided project management, ROV operation and diving work and a third party provided additional UXO expertise at the time. In addition to the part played by Martens en Van Oord, the main contractor, Bluestream, took care of the project management, the ROV operation and the diving work. This was a dynamic team that had all the qualities and facilities in house to bring this project to a successful conclusion.

Fully certified 
Since 2022, Martens en Van Oord have been fully certified in accordance with the Certification Scheme for the Detection of Explosive Remnants of War (CS-OOO). That means we are authorised to mitigate the risk posed by explosive remnants of war for our clients. We do this by guiding our clients through the detection process independently, safely and in accordance with the laws and regulations. We also offer them civil engineering support (sub-area A and B).
