reaching first production, especially in smaller or marginal fields.
Their future redeployment, however, is not a certainty. Once industry
conditions rebound sufficiently to make these vessels attractive for
reuse, however, there are potential hurdles that must be addressed.
Technical and constructability issues could be a problem for vessels
to return to the active fleet. Of the 19 available vessels noted in this
year’s annual FPSO survey and poster, more than half are fabricated
with a single hull. While this feature makes them considerably less
expensive and quicker to convert, their usefulness, once converted,
can be compromised. Since they are already in maturity from previous
service, their structure makes them more susceptible to fatigue and
a shortened useful life. That single-hull construction, in the US Gulf
of Mexico and other production regions, makes them unacceptable
to regulators and certification agencies.
Several vessels have undergone multiple redeployments and are
nearing the end of their useful life. For example, the Petrojarl 1 is
awaiting its 11th reassignment since its first service 30 years ago. Its
next assignment, offshore Brazil, is the first of its redeployments
outside of the North Sea.
This factor could be beneficial due to the less demanding environ-
ment to which it is going. However, to determine their serviceability,
available vessels undergo a thorough cost/benefit examination to
determine if they are indeed redeployable or should be permanently
decommissioned and scrapped. Depending on the selected field for
reuse, a stacked vessel needs to be thoroughly inspected and found
structurally and commercially suitable with its existing mooring,
accommodations, topsides modules, and anticipated turret loads.
Altering these components can lead to significant expenditures and
Other issues can hamper the cost of refurbishment and re-intro-duction of an out-of-service vessel. Reservoir characteristics of a new
field could impact the effectiveness of the topsides facilities. Fluid
viscosity, pressures, temperatures, and suitability of current gas
compression and dehydration can require replacement or addition
of upgraded capabilities.
Flow rates vs. storage capacity have to be analyzed. While many
conversions are from VLCCs with large storage capability, smaller
storage vessels can require de-bottlenecking and more frequent
production offtakes from the FPSO to shuttle tankers, diminishing
the commercial feasibility.
All offshore oil and gas businesses are being prompted by the
Internet of Things (Io T) to shift their operational paradigms into
the digital world. FPSO contractors and producers are no exception.
Their goal is to increase productivity and reduce costs, but there is
no “one size fits all” solution. Rather, FPSO operators are continually
adapting and fine tuning their assets in real time using trend analysis
and data analytics. These cutting-edge tools and software can be
valuable predictors of potential failure by incorporating repair his-
tory, operating conditions and fleet data. The analytic tools can also
determine probable root causes and estimate remaining useful life
of topsides components.
Many FPSO owners and operators are incorporating Io T and these
digital tools into their vessels while idle and upgrading their systems
on newbuild vessels. The end result, if data is integrated within their
organizations, could be substantially increased production efficiency
and dramatically reduced operating costs. •
