Esquimalt Graving Dock has several jetty structures which provide safe pre-docking moorage for ships, some of these jetties are deteriorating and wharf replacement is required. The Phase 2 Environmental Remediation project includes demolition of the two timber jetty structures and all associated utilities at the South Jetty. As part of this project, the electrical utilities require modification, and in some cases decommissioning and removal.
The client requirement was for the modification of the electrical and communication services which are carried under the jetty on a timber catwalk, to ensure the systems remaining were functional and the demolition could take place safely.
This design work was followed by regular site inspections and contractor support during service relocation and decommissioning.
The electrical work includes site investigations, existing drawing review and creating multiple demolition drawings to instruct the contractor on scope. A cable schedule was created indicating the modifications required to the systems. Modifications to the impressed current cathodic protection system were also included in this design.
This multi discipline project involves structural, electrical and mechanical service scopes to document the demolition requirements.
- Electrical power distribution modifications
- Electrical cable termination details
