ABSTRACT:
The present invention relates to a subsea pipeline and method utilizing the pipeline wherein the loss of pipeline contents resulting from a break in the pipeline is reduced. The loss of pipeline contents is reduced by providing a plurality of traps in the pipeline. The traps each comprise at least two elevation changes in alternating directions. Any water entering the pipeline through a breach will only displace pipeline contents from the breach to the adjacent lower trap.
