With oil at USD 50/bbl, only the biggest deepwater discoveries can justify the cost of a new production platform, and even those projects demand an intense focus on shaving every possible cost to allow profitable development.

The few projects going forward now are generally sending the oil and gas to a platform built for an older field.

The need to tie back production to aging facilities puts a premium on extending the life of critical components offshore, including the chains and lines that anchor floating structures and the risers providing a conduit for the pipes and lines running to subsea systems and export pipelines.
