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

Monday, 25 June 12

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

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

Monday, 25 June 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

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

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

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

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

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

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

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
