This page broadly describes our planned approach for the project to bring the City of Adelaide clipper ship back to South Australia. It is anticipated that these details will be further refined during detailed design and planning. They are dependent on a detailed site survey as well as the equipment and methods ultimately used.
The plans are presented using a Work Breakdown Structure, which is a fundamental project management technique for defining and organising the total scope of a project, using a hierarchical tree structure.
The project is broken down into a series of Phases. Each phase is then broken down into a series of Stages.
The high level phases are:
- Phase 1: Remove the clipper from the slipway.
- Phase 2: Transport the clipper to South Australia.
- Phase 3: Preparations to receive the clipper in South Australia.
Phase 1 - Remove the Clipper from the Slipway
The objective of this phase is to remove the clipper from the slipway and move her onto a barge. The stages within this Phase are:
1.1 Technical Preparations - development of detailed plans and drawings for subsequent stages of project.
1.2 Cradle - construct the transportation cradle for subsequent lifting and transporting of clipper.
1.3 Clipper - prepare the clipper for moving.
-
- Install transportation cradle.
- Prepare clipper for moving – Shore and brace parts of ship in accordance with Naval Architects report.
- Raise and level the ‘City of Adelaide’ using hydraulic jacks.
- Support the transport cradle on temporary concrete blocks.
- Remove the existing cradle.
1.4 Slipway - remove bund and dredge in way of slipway.
-
- Fill and compact the slipway with gravel/crushed rock/dirt to Engineer’s specification.
- Level the bund at the end of the slipway and compact.
1.5 Barge - land on sill and ballast down barge.
-
- Bring in flat-deck barge, ballast down and secure.
- Fill and compact the gap between the barge and existing bund at end of slipway.
- Hoist clipper with multi-wheel transporters.
1.6 Transfer - push transporters and clipper with prime movers on to barge.
1.7 Towage - deballast barge and tow barge and clipper to an Irvine wharf, pontoon or other interim location while awaiting dockship/heavy-lift ship.
