Overview
A major operator was seeking to develop marginal fi elds which required innovative, low-cost methods to enable cost effective development.
Scope of Work
The client approached Jee to undertake a study with the objective of identifing CAPEX reduction in pipeline construction methods, installation techniques and labour resources.
The benefits
The development included several monopod structures, pipelines and two manifolds. Our experienced team utilised their experience and Jee’s cost database to identify the potential
savings, which included the following aspects:
- Reduction in pipeline diameter resulting in a materials cost saving
- Revising the pipeline configuration by replacing manifolds with risers and subsea tees, and re-routing a pipeline via an existing export line to avoid a landfall
- Construction methods: using a local barge to lay the pipeline using mechanical connectors, thereby reducing vessel time and costs
- Piggyback line: using topside corrosion inhibitor tanks to replace piggyback line
Results
After reviewing and recommending changes to the concept design, Jee performed a cost analysis of the procurement, construction and installation of the system. The analysis showed that by implementing our changes to the proposed system design, a total cost reduction of 41% could be made. This included savings of approximately $5.6 million due to the lower material requirements for the smaller pipe and $19 million by re-routing the pipeline to avoid a landfall. Resulting in a total cost saving of approximately $24.6million.
As an independent company we are able to align ourselves completely with the business objectives of our client, providing impartial advice and the best possible solutions.
