 D & R Cutting – Tilbury Docks 

 

CASE STUDY: Dismantling a Quayside Container Crane

IDI Services Supports D & R Cutting with Crane Demolition at Tilbury Docks

Client Profile

D & R Cutting is a specialist cutting and dismantling contractor. At the Port of Tilbury on the Thames, D & R Cutting was engaged to dismantle a redundant quayside portainer container crane, a major structure standing on an operational dockside. IDI Services travelled well beyond our Aberdeen base to support the project.

The Challenge

Taking down a large quayside crane is a complex engineering operation with many risks to control:

  • The crane structure was large, tall and heavy, with sections that had to be cut and lowered in sequence
  • Heavy machinery houses, beams and legs needed controlled tandem lifting
  • The work took place on an active port with container operations continuing alongside
  • Each section had to remain stable as it was cut free from the main structure
  • Weather and wind on the open quayside had to be monitored constantly

The Solution

IDI Services designed a comprehensive approach using our specialist equipment and expertise:

Phase 1: Engineering and Sequence Planning

  • Worked with D & R Cutting on a step-by-step dismantling sequence
  • Assessed section weights, centres of gravity and rigging points
  • Coordinated lift plans with the large mobile and crawler cranes on site

Phase 2: Lifting the Upper Structure

  • Rigged and lifted the machinery house and upper sections clear of the structure
  • Lowered loads under full control onto the quayside for processing

Phase 3: Main Beams and Legs

  • Main beams were supported by cranes in tandem while cutting crews released them
  • Sections were lowered to the ground and the legs taken down in turn
  • Access platforms gave safe working positions at height

Phase 4: Clearing the Quayside

  • Dismantled sections were laid down for further cutting and removal
  • The work area was handed back to the port

The Results

The project was completed with excellent outcomes:

  • Redundant container crane safely dismantled in planned sequence
  • Large sections lifted and lowered without incident
  • Port operations able to continue around the works
  • Close cooperation between all contractors throughout

The IDI Advantage

This project shows that IDI Services' lift planning and rigging expertise travels well beyond the north east of Scotland. Working as part of a multi-contractor team on a major port demolition, we helped deliver a complex job safely.
