It is generally accepted that 10% of all aerial bombs and 30% of incendiary devices dropped during the WW2 failed to function as intended and a certain amount are possibly still buried in the local geology or present on the seabed.

There is an increasing rise in development in ports and harbours, with this a number of marine development and construction companies have been known to encounter unexploded ordnance (UXO's). Once discovered a dive team is then needed to uncover and eliminate or rule out all potential UXO's.

Because of this nearly all intrusive operations such as dredging or piling around major ports on the coast now take preventative measures in lowering the risk ALARP, they do this using side scan, 3d chip, magnetometer and sonar to identify any potential targets.

Our highly trained teams help to provide an avoidable solution to a potentially high risk unknown hazard that could be detrimental to people, equipment and structures.

MMC Diving Services were selected to provide the teams and equipment to assist Fellows UXO specialist in UXO threat assessment, risk mitigation, target identification and removal and disposal of items found within the International ferry Port in Portsmouth Harbour.

Our operating procedures are applied by the most appropriately qualified people, they ensure safe and efficient operations in any underwater environment.

To quantify and mitigate any UXO risk wherever it may be present following a survey, as UXO our approach described within CIRIA C681 follows all UK HSE guidance and is based upon the ALARP (As Low As Reasonably Practicable) approach. This approach also recommends that proactive risk mitigation measures are employed whenever possible and reactive measures are only employed as a last option.

Should you have a requirement in the future, our highly qualified and experienced, ex- Royal Navy bomb disposal operators, and Level 8B1 qualified Maritime Ordnance Explosives Superintendents are able to mobilise at short notice to address the threat posed by ordnance in the marine environment.
