3. The TOPS Concept
• The average water depth in the world is
3795m and this is a solution for the future
for both shallow and deep water
• all offshore oil and gas will based on having
a continuous process including appraisal,
production, and refining and for certain
fields, transport ship (TOPS)
• most of the patents have lapsed but
patentable positions remain

4. The First Project
• The Irish Authorities have been approached
to develop Barryroe in conjunction with
the current Licence holders
• Intend to work with Lloyds Registry and
have IOM flag
Monday, 25 June 12

5. TOPS Eliminates
• delay in appraisal and development
• conventional rigs and platforms
• Note: Eboroil has a frame agreement with
Shell to sell the product from Barryroe and
others

6. Schedule
• Site survey and studies -
15 months
• Construct Mooring
tower - six months
• Install riser tower - one
day weather window
• Pre-Install production
template - 60 days
• Drill - 15 plus days
• Start Production

7. Preliminaries
• establish bottom conditions, sea water
properties as well as wave and current
profile at the site (GEMS)
• establish if affecting marine mammals,
seabed corals and migratory bird paths
(NPL)
• shoot 3D seismic of the area
• establish that when the reservoir is de-
pressurised that there is no earthquake risk
(Geomec)

8. Components
• Mooring tower in steel in shallower waters
and Titanium in deep water (Mercon)
• Well template with co-mingled production,
water and gas injection services together
with subsea processing
• A Suezmax tanker with dp2 or dp3
depending on legislation providing direct
well access for drilling and intervening
throughout the field life
Monday, 25 June 12

9. Appraisal Phase
• Design site specific TOPS mooring tower in
steel/Ti with 2000 ton barytes ballasted
base (Mercon with SBM as subcontractor)
• Install template and flowlines (Technip/
others?)
• Mobilise the TOPS ship and drill first well
• In event of dry well redeploy equipment
Monday, 25 June 12

10. TOPS Mooring Tower
• 2000 tons of barytes ballast in the base
• Upper buoy contains ballast tanks to allow
for installation and removal - reuseable
• Lower buoy at minus 160 ft have hose take
offs to the TOPS ship - site specific
( Contitech/Aker ?)
• later in the concept there can be ocean
energy off wave energy and unidirectional
currents to generate H2 for the dp system
(Magnomatics/ITM Power)

11. TOPS Template
• 4 by 8 on 8’6” centres well slots
• each Christmas tree to be connected to a
co-mingling distribution manifold on the
central two rows for production at the
flowing wellhead pressure of the best well
and subsea separation.
• use duplex acoustic controls with hydraulic
accumulators on the template
Monday, 25 June 12

12. Subcontractors
• Nemo Engineering - pipeline sledges
• Acoustic controls - used Cameron
successfully before and Kongsberg
• Water injection pumps, artificial lift, gas
injection and compression - Clavis are
developing a unique pulse based pump
technology
Monday, 25 June 12

13. TOPS
• station keeping by Dp2 with constant
tension mooring winch working at between
70 and 90 tons (Huismann/AXTech)
• parcel size for 600k bbls of production with
constant draft while drilling
• Receive oil, gas, water and distribute oil,
gas, drill cuttings removal and pigging
services
Monday, 25 June 12

14. Drilling
• 30” conductors installed on all wells in the
construction phase (Technip)
• use rotary drilling for Barryroe
• later Casing Drilling technology to drill
underbalanced in a closed loop to contain
kicks (Schlumberger)
• use composite cable based push/pull
wireline (supplier yet to be chosen) to
retrieve bits etc
Monday, 25 June 12

15. Drilling Operations
• Mount rig over moonpool
• Have top drive for rotary and coil for
intervention
• Recover and treat drill cuttings with
biodegradable oil solvent and dump cuttings
• have slip joint design by Aker after their
experience on well intervention vessels
Monday, 25 June 12

16. Process plant
• Have main processing subsea for separation
of oil, gas and water
• Mount equipment 3 m above cargo holds
• Have surface oil treatment as heating to 80
deg C to remove metals with activated
charcoal and then crack at 400 deg C to
diesel product specifications with a catalyst
• Have chemical injection and pigging services
Monday, 25 June 12

17. Maximise Oil Recovery
• Continuous monitoring of reservoir behaviour and
optimisation of offtake using multiple realisation of
static and dynamic reservoir models.
• Continuously drill and intervene guided by 4D
seismic
• To inject gas super critically until reservoir until
dry
• Inject cation rich sea water to recover oil prior to
low surface tension water to break up macro oil in
water emulsions
Monday, 25 June 12

18. Ocean Energy
• Install wave energy
generators to
provide power in
storms
• Install
unidirectional
current generators
for mid-water
installations for
constant power
load
• install in 90deg arc
Monday, 25 June 12

19. Ship Operations
• Have Captain in charge of all operations
• Change crew every three weeks and
recharge activated charcoal using the dry
evacuation system (GEC)
• Later in concept - Have unidirectional
currents and wave energy generate
hydrogen for dp system (Magnomatics/
Pulse Tidal/Green Fuel/ITM Power)
• Be a zero emission ship
• Have shuttle tankers use a Remora unit
Monday, 25 June 12

20. Contingencies
• Have two dp UT 705 offshore platform support
vessels with active stability tanks and acoustic
responders to shut down the template in case
of problems
• Have oil skimming with a biodegradable oil
dispersant, bulk barytes, cement, fi-fi services,
anti collision radar, dry evacuation transfer
service as a stand-by service
