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

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

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

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 Production6

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)

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

Page 9: 120625 0814 Tops

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

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)

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

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

Page 13: 120625 0814 Tops

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

Page 14: 120625 0814 Tops

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

Page 15: 120625 0814 Tops

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

Page 16: 120625 0814 Tops

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

Page 17: 120625 0814 Tops

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

Page 18: 120625 0814 Tops

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

Page 19: 120625 0814 Tops

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 unitMonday, 25 June 12

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
