Dockyard Water Control Barriers Refurbishment

Client: Babcock Marine

Location: Devonport Dockyard, Plymouth

Project: Refurbishment of dockyard caissons, flap gates and dock gates

Standards: BS EN ISO 12944-2:1998

Services: Access, containment, metal surface preparation, painting



Working as principal contractor to Babcock Marine, Denholm Industrial Services (DIS) undertook a multiple asset project to refurbish a number of dry dock related water control barriers.

Services delivered:
  • Scaffold access
  • Containment
  • Steel surface preparation
  • Painting
  • Mechanical and electrical works utilising Relay

The works involved preparation of substrates that were heavily contaminated with sea salts and the application of protective coatings both above and within splash zone areas.


The Challenge 

The operational requirements of a busy Ministry of Defence dockyard and the need to work within the tidal patterns provided frequently varying challenges. 


The Solution

Working patterns and resource management were continually adjusted to meet the evolving circumstances and to avoid programme delays.  Additionally, 'lessons learned' were applied as the project developed, making the work increasingly more cost effective.

The project involved working over water and working at height - diligent and safe working practices were maintained throughout.
