The IFL technology provides the offshore operator with an extremely economical alternative to subsea pipeline replacement when comparing these options in case a subsea pipeline reaches the end of its design life.
Major savings in the time required for FEED/Design/Planning/Production can be realized using IFL, as an IFL subsea pipeline rehabilitation process covers between 4-5 months, compared to 12-18 months for a new-lay carbon steel (CS) pipeline campaign.
The major capital expenditure savings however, are realized in the installation part of the project, whereby the deployment costs of a small IFL installation vessel stand in no comparison with that of a large lay barge vessel, required for offshore CS new lay.
In addition to the capital expenditure savings, there are 3 major areas of savings in life time operational expenditure as a pipeline rehabilitated with IFL eliminates the need for:
The operational expenditure savings from the above outlined components can amount up to a very significant amount over the operational life time of a pipeline.
Overall, IFL subsea pipeline rehabilitation substantially reduces the pipeline’s total life cycle costs.
