Wharf Capabilities Project
Wharf Capabilities Project
CHEVRON REFINERY
Project Value: $1.1 Million
Background
In order to improve product transportation efficiency to the wharf from various locations. Chevron contracted Goebel Construction to modify its piping to improve efficiency.
Scope
- Pipe Prefabrication
- Pipe Support
- Line Resize
- Addition of Thermal Reliefs
- Pipe Demo
- Pressure Release Device (PRD)
- Supports
- QA/QC Tracking
- Tie-ins to existing lines
- Valve Changes at pump station
Project Highlights
- 156 Welds
- 600 ft of pipe demolished
- Utilization of pipe tugging method was safely implemented which resulted in cost savings for the client.
- Foreman forecasted manpower needs to control costs
Challenges
- Piping Demo Scope of work included working on a hillside with limited accessibility.
- Multiple work-site areas with overhead powerlines
- Scheduled outages left minimal room for error to complete the project on time.
Solutions
We collaborated with operations to map out a new pipeline combined with existing underutilized routes. The field data gathered and the proposed plan was used by engineering for the final work construction package. To save costs, we prefabricated the welds to lower the number of field welds.
Project Success
The project was completed without any reported injuries or environmental incidents for a total of 5,250 man-worked hours. Completed the project by end of the year in order to use allotted funding.
Crafts Supported
- Pipefitters

CVX/EBMUD RO Plant
CVX/EBMUD RO Plant
CHEVRON REFINERY
Project Value: $4 Million
Scope
Expand plant to receive and process EBMUD reverse osmosis water.
Challenge
We needed to install 3,500LF of 316 stainless steel pipe from EBMUD to Chevron’s treatment facility. This work included site excavation and grading, concrete foundations, installation of pumps and filter, pipe racks and critical tie-ins during the plant shutdown.
Solution
