DP FPSO – Well Proven Technology
(SWOPS Single Well Oil Production System)
1989 BP take delivery of DP FPSO Seillean and operated on Cyrus field. The
vessel served on the Cyrus Oilfield in the UK and then the Donan oilfield.
1993 BP streamlined business and sold Seillean to Reading and Bates who
continued to operate the vessel for BP.
1998 Petrobras approached Reading and Bates – while they were negotiating
with Premier for development of Chestnut field – with a requirement for an
early production vessel. This led to a six-year contract between Petrobras
and Reading and Bates.
1999 Operated on the Roncador, Jubarte and Golfinho fields.
2010 Seillean contracted as oil collection and processing facility on the
Macondo oil spill.
In 2008 Petrobras commenced a build of their own version of the Seillean DP
FPSO (the Dynamic Producer), which has since been utilised for extended
well testing in the Espirito Santo and Campos and Santo basins, in Brazil
2004 Munin operated on DP for Conoco Phillips on Xijiang field
2010 Munin operated on DP for 18 months on Huizhou Field for CACT
2005 Hurricane Rita destroys Typhoon field tension leg platform
2008 Helix convert ice class train ferry to dynamically positioned

General Safety West of Shetland (WoS) Operations
Both Amplus’s MD and Technical Director have extensive
experience of operations West of Shetland, which
resulted from the award by BP to Sub Sea Offshore
to manage the construction activities related to the
installation of the Schiehallion Field, WOS.
This included manifold installation and remote tie ins,
flowline installation, FPSO mooring installation and tow
out of the FPSO and riser installation.
All construction activities were undertaken from DP
vessels and as a result of the experience gained, Sub
Sea Offshore specified a new DP construction vessel,
the Subsea Viking, which has been actively employed
on construction and maintenance by BP for many years,
WOS.
Safety was a priority for BP in the challenging environment
and subsequently Sub Sea recommended Managing
Director safety forums to share safety learnings. The
forums were successful and continued for several years.
The effort was recognised by BP, which is reflected in
the commendation letter attached.

VPU Operability
The Amplus VPU is designed to operate “Head to Weather”
at all times. The VPU is so powerful, with an excess of 24
Megawatts of installed power, we can never envisage a
situation of having to dis-connect for anything other than a
planned event.
The Modelling we have done shows that the VPU can
remain on station in Hurricane Force Sea conditions and still
only use around 35% of her installed power.
A recently completed study for a major oil company proved
that the Amplus VPU 200 could remain connected 365 days
per year in the West of Shetland area of the UKCS.

DP FPSO Classification
To assure core marine safety and integrity the vessels hull,
machinery and equipment will be constructed under survey
of Llyods Register Classification to obtain the notation:
+OI 100 A1 Floating Production and Oil Storage Vessel +LMC,
GF, UMS, IGS, LI, DP(AAA), SDA, FDA, Heli Deck
Maintenance
The vessel is designed and outfitted for a five year dry dock
period and in water intermediate inspection. Maintenance
has been considered in the design phase and storage tanks
equipped with deep well pumps to simplify maintenance.
During the design phase Houlder Offshore Ltd undertook a
study to determine the strategy to minimise interfaces and
thereby maintenance issues for the major vessel machinery.
The disconnectable turret enables simple disconnection from
the sub sea infrastructure and permits the vessel to move
to harbour where full facilities in controlled conditions are
available for any major maintenance or modifications required.
This can be undertaken if required during routine export
pipeline shut down periods for example.
It is intended to have the planned maintenance system
developed during the build programme and the system will
be managed in operation by the chief engineer.
It is intended to employ the OIM/Master, Chief Engineer
and Electronics technician on commencement of the build
programme.
Accommodation
Notwithstanding the fact that the vessel can be easily moved
inshore for major unplanned maintenance and modification
the vessel is designed with 100% redundancy over regular
crew accommodation requirements.
Crew welfare was identified as a key parameter by the
Health and Safety Executive in delivering a safe and efficient
operation and has been considered in the design of the
accommodation and associated facilities.
Accomodation is for 70, comprising 20 crew mainly in single
cabins and 50 service personnel in single and double cabins.
The following fully furnished offices are provided: Engine
Room Office, Catering Office, Reception Office, General
Office, OIM office and Conference Room for 14 persons.
Public rooms include Coffee shop/duty mess, Mess Room
to seat at least half compliment, Two dayrooms/recreation

Amplus VPU Inherent Integrity
VPU Power and Station Keeping Integrity
For installations on the UK Continental Shelf (UKCS), the Health
and Safety Executive (HSE) Offshore Safety Division requires
operators to use suitable and sufficient risk assessment to
demonstrate that risks have been made as low as reasonably
practicable. For DP systems, this is normally satisfied by an
FMEA and trials.
Amplus have specified in the VPU design requirements that
the FMEA will be a holistic study to include the process
system and riser turret.
Vessel Management System
Amplus are aware that incidents have occurred on offshore
vessels as a result of failures in the design process for PLC
controlled systems.
The Vessel Management System will provide operational
personnel with the real time information and control interfaces
necessary to safely and efficiently manage vessel operations
as well as assure safety of personnel, process and machinery.
To achieve this safety objective, it is essential that the vessel
owners and operators, equipment vendors and automation
system integrators follow a clearly defined process to assure
the functional safety of the automated VMS during the
complete life cycle, from concept to commissioning.
Amplus Energy have specified the process defined in the
IEC61508 and IEC61511 standards (IEC=International Electro-
technical Commission) to provide assurance of the integrity
of control systems.)
Helideck
Amplus Energy commissioned a design review by Houlder
Offshore Ltd to optimise the position of the vessels helideck
to minimise helideck movements while meeting other
helideck design regulations.
Green Water
Lessons have been learnt from Green Water incidents
and Houlder Offshore have reviewed and reported on
measures taken in the vessel design to obviate the risks.
Final confirmation of the success of these measures will be
confirmed during the planned model testing.
Cranes
FPSO’s have conventionally been equipped with fixed boom
cranes but to improve operability Amplus has specified a
knuckle boom crane for supply boat operations.
14. 12 BP | AMPLUS VPU
Environmental Discharges
Produced Water
The National Oilwell Varco process system will be
equipped with a Compact Flotation Unit (CFU)
The inlet to the CFU is produced water from the
Deoiling Hydrocyclone and produced water from the
Electrostatic Coalescer.
It is the final polishing step in the produced water
cleaning process and the outlet specification of
the CFU is less than or equal to 20 ppm at which
concentration water can be discharged overboard.
The produced water treatment of the Lancaster Field
Product is not onerous for the NOV process system but
In the unlikely event of out of specification produced
water, a return line to the slops tank is included with
constant monitoring available.
Flaring
Amplus has specified that the VPU will be provided
with Wartsila dual fuel engines to provide maximum
operational flexibility and reduce OPEX costs.
To assure the VPU can operate on a range of associated
gas with either large amounts of heavier hydrocarbons
or variable low methane compositions: the VPU will
be equipped with Wartsila GasReformers.
The traditional way of getting rid of associated gas is
either flaring, or burning in boilers, or gas turbines with
high operational costs and low efficiency.
The Wartsila Gas Reformer has the following
benefits:
Reduction in CO2 emissions
Minimise/cut flaring
Low NOx from dual fuel engines
Dual - fuel engines can operate on full load
and efficiency
The Wartsila GasReformer has been approved
by DNV and is field proven
Wartsila state an 8MW gas reformer reduces
flaring by 1.5 million standard cubic feet per
day and the VPU will have 3 x 8MW reformers
installed.
This combined with the associated gas
required for thermal oil heating boilers – for
VPU storage tank heating – should consume
the majority of associated gas from the
Lancaster field – Circa 6MMSCF / per day

21. 19 BP | AMPLUS VPU
Quick Connect Disconnect Connector (QCDC)
FES have worked very closely over the past 10 years to develop a QCDC – a key component
– with a maximum capacity which allows the system to be safely disconnected in a matter
of seconds without any spillage of oil, and to allow for a safe re-connection in a matter of
hours. The QCDC consists of a number of interlocked valves and hydro-electric umbilical
quick release stab plates. The upper half of the QCDC is connected to a turntable structure
mounted on the vessel to allow the risers / umbilicals to maintain a geostatic position whilst
allowing the vessel to weathervane 360 Degrees, thus maximising operational uptime. The
lower half of the QCDC is connected to a buoyancy unit (riser buoy) which disconnects to
go subsea.
The Current QCDC Design Limitations
The current QCDC design limitations would
be based on the following:
Total QCDC load capacity including full
pressure loads = 2000 Te
Total Structural capacity excluding pressure
loads = 1500Te (approx.)
6 –off 6inch NB 5000 PSI fluid flow lines
3 – off Hydro-electric disconnectable
stab plates
Maximum connected riser and umbilical
tension = 25 Te (each).

VPU Safety Case
Amplus have developed a generic draft safety case and
draft design notification, and these will ultimately be
finalised against a specific development.
During a paid feasibility study for Maersk Oil and Gas, a
one-day HAZID was conducted with Maersk facilitated
by ERM, with no major issues identified.
At the request of Hurricane Energy a meeting was
arranged with the Health and Safety Executive to
review the VPU concept which was also attended by
EPC Ltd (now Costain). The HSE were very supportive
of the concept and only commented on the need for a
high standard of accommodation for offshore crews.
Additionally, there was a day in the North Sea when
there was no wind that had caused an issue with cold
venting on an FPSO, which Amplus should consider.
Amplus amended the VPU design to mitigate any risk
associated with cold venting.
The HSE undertook to review the detailed vessel
specification on an informal basis and only had minor
comments on the specification.
The VPU was approved by the marine technical
authorities in both Maersk and ConocoPhillips.

Shipyard Selection
Amplus has undertaken three rounds of enquiries to shipyards for lump sum quotations for the VPU vessel build
First Round 1
Houlder developed an outline VPU specification for initial pricing to determine the vessel would be built
at a price that was acceptable for the development of marginal oilfields
Budget prices were received from Far Eastern and European shipyards which determined that the
CAPEX cost for the vessel were acceptable
Second Round
Houlder went on to develop a 100 page specification for the second round of bidding. This was for the
100,000 barrel storage capacity vessel with a rigid drill pipe riser system.
Both the Hyundai Mipo shipyard in Korea and the Wadan Shipyard in Germany provided attractive
quotations.
2
During the evolution of the VPU design it became apparent that the single riser did not offer the flexibility
required by prospective clients to provide gas lift, gas export, power for ESP’s multiple production risers.
Amplus then identified the FES disconnectable turret system which was North Sea field proven and had
been accepted by the US Coastguard for use in the Gulf of Mexico. The turret was incorporated in the
design and Houlder undertook some steelwork design work in the moonpool area to confirm the turret
could be integrated into the vessel.
Several clients requested more storage capacity and in response Houlder were commissioned to write
a more detailed specification for a 200,000 barrel unit with the FES turret system.
This 300 page specification was issued to Far Eastern and European shipyards. Consequently the most
attractive offers were received from Vard in Norway and Dame in Holland.
Shipyard slots are available at Vard and Damen in the third quarter of 2016 with a 24-26 month delivery
schedule for the VPU.

8MW Wartsila Gas Reformer
Whenthefinalflowlineandtankheatingrequirements
are established, our study conducted by Houlder
into the use of associated gas through the Wartsila
Gas Reformers concludes that we would effectively
use 6 mmscfd of associated gas per day for power
generation and heating requirements.
The associated gas separated from crude oil is often
flared because it varies in composition and contains a lot
of heavier hydrocarbons and is an unreliable fuel source.
The Wartsila GasReformer Technology is based
on steam reforming a catalytic process from the
petrochemical industry.
The methane number of any fuel gas is improved up
to 100 + or - 5 by converting the heavier hydrocarbons
to synthesis gas and finally to methane.
With the Wartsila GasReformer dual fuel engines
can be utilised with high efficiency, reliability and
flexibility.
