Commercial Diving & Marine Services were established in 1971 initially concentrating mostly on offshore salvage work. Ever since these early days, the company has expanded, to incorporate major civil engineering, contract, salvage and filming projects. With this wealth of experience, the company has firmly established itself as a leader in the diving industry throughout the UK.

The divers at CDMS are fully qualified to the health and safety diving operations at works regulations, and adhere strictly to the approved codes of practice. Furthermore each diver has an annual medical examination to confirm good health and peak physical fitness. Our diving teams are trained in casualty handling, CPR and also hold first aid qualifications.

CONCRETE DAM (BEFORE)

A reinforced concrete dam prevented access to a large marina, as a result, CDMS were requested to look into the logistics of its removal.

After careful analysis and calculation the structure which had been in place for over 40 years was successfully removed using the latest approved methods.

 

 

 

 

CONCRETE DAM (AFTER)

The final photograph shows the complete removal of the concrete dam wall.

 

In order to gain full access for marine craft, the secondary sheet steel pile wall needed to be cut off below the basin invert level. This would ensure that all vessels would have a safe passage through the channel without risk of damage.

BRIDGE MAINTENANCE

Bridge works form an important part in the CDMS work schedule, from condition surveys to clearing vegetation, placing rock armour to removal of debris all play an important role in the every day activities of the company.

The photograph opposite shows a recent project on a railway viaduct crossing a fast flowing river. The water flow and volume resulted in the formation of very deep scour cavities which severely affected the structural foundations. CDMS divers were brought in to survey the structure, report on the severity, and in liaison with a company of consulting engineers assisted in a bespoke remedial repair design which was suitable for the delicate ecology of the river and this successfully underpinned the bridge.

The resultant repair enabled the line to be reused so saving the operator thousands of pounds in lost revenue.

LOCK MAINTENANCE

Jack up barge and support craft assist a CDMS diver to position steel stank's on a large lock stoppage. The 9.8m wide lock was successfully dammed off and de-watered after placing 17 individual stank's to a depth of 7.6m before which 1.5m of silt and debris needed removing from the cill.

At the conclusion of the remedial repair works the stank's were removed as reciprocal operation.

BURNING AND CUTTTING

Permanent and temporary steel structures play an important role in marine construction projects. Steel piles, cofferdams, supports, bracing's often need to be removed to make way for new works or improvements which involve modification. Here we see one of our divers cutting through sheet steel piles to enable attachment to the crane prior to removal of a cofferdam.
