We work in close collaboration with our clients. This not only ensures safe operations, but furthermore, a cost effective realisation of their maritime projects with regards to UXO risk mitigation. We really care about our clients project goals and we alleviate our clients accountability by taking full responsibility for the entire management of the UXO scope of work, providing an all-inclusive package.

UXO risk mitigation projects can be particularly difficult to manage. To manage complex projects of this nature a phased approach is essentially required. NjordIC applies a phased approach to UXO Risk mitigation. The level and extent of activities in each phase will highly depend upon the findings of the preceding phase. This phased approach is aimed at decreasing the amount of project management risks in the subsequent phases of the UXO risk mitigation process.

Step 1

Historical Research

Profound and detailed historical research is indispensable as the foundation of each successful UXO risk mitigation project. The available historical information is gathered from e.g. archives, literature and open sources. Based upon the consultation and evaluation of the historical information, the war-related events and/or dumping events relevant to the area are identified and analysed. Subsequently the likelihood of presence for the main categories of UXO is determined. Finally the types/calibres of the UXO likely to be present are detailed.

NjordIC has access to all relevant archives and databases. We have excellent contacts with relevant experts specialised in war-related history

Step 2

UXO Risk Assessment

In assessing the overall UXO risks for a project, a Semi Quantitative Risk Assessment (SQRA) process is applied. SQRA is considered by NjordIC to be the best practice in the offshore industry. The assessment is based on the conclusions of STEP 1, the planned working methods & equipment, the likelihood of a detonation occurring and the effects of a detonation. If the SQRA identifies that a risk reduction is required to ensure safe working conditions, the mitigation measures generally consist of:

  • UXO survey
  • Avoidance of significant objects,
  • Identification of potential UXO objects which cannot be avoided
  • Disposal of actual UXO where avoidance is unachievable or practical.

NjordIC will continuously strive to implement and manage the most pragmatic solution. The scope of work for the UXO risk mitigation measures is determined by assessing the appropriate threshold levels for modelling of anomalies detected by a UXO survey, the maximum burial depth of UXO below the seabed, UXO migration and other parameters relevant to the area.

Step 3

Project Management Plan

It is essential to ensure the UXO risk mitigation strategy outlined in the UXO Risk Assessment is embedded into the project documentation. NjordIC provides the project management documentation for the project including, but not limited to Project Execution Plan, Hazard Identification and Risk Assessment Plan, Quality Assurance / Quality Control Plan. Also Stakeholder Management is utilized at this stage, involving local stakeholders and EOD authorities, to clear the path for smooth operations.

NjordIC is also able to organize and present the project kick-off to ensure a well-prepared team to start operations

step 4

UXO Clearance Operations

The UXO clearance operations are performed by the selected contractor and consist of 4 sequential steps:

  1. Survey and detection, involving a variety of different survey techniques and platforms.
  2. Classification & identification, involving ROV, WROV and EOD divers,.
  3. UXO removal.
  4. UXO disposal by the local EOD authorities or contractor (depending on the location legislation).
NjordIC can assist in the EOD-management, the QA/QC procedures and the ALARP sign-off on behalf of a Contractor but also in Client Representative roles representing the Employer. Due to our indenpendent position we can act on both sides.

NjordIC is also active in validating survey techniques and actively looking for new techniques or combination of techniques with the sole purpose of making UXO clearance as efficient as possible.
