The TOPS Concept

• The average water depth in the world is 3795m and this is a solution for the future

• all offshore oil and gas will based on having a continuous process including exploration, production, and refining and for certain fields, transport ship (TOPS)

• most of the patents have lapsed


TOPS Eliminates

• delay in appraisal and development

• conventional rigs and platforms

• refineries

• over balanced drilling as per the BP GOM blow-out

• significantly lowers blow out and pollution risk in arctic areas and in deep water


Schedule• Site survey and studies -

15 months

• Construct Mooring tower - six months

• Install riser tower - 1 day weather window

• Pre-Install production template - 60 days

• Drill - 15 plus days

• Start Production5


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 and heavy oil splitting services together with subsea processing (FMC/others ?)

• Aframax sized TOPS with dp 2 providing direct well access for drilling and intervening throughout the field life


Exploration Phase• Design site specific TOPS mooring tower in

steel/Ti with 2000 ton barytes ballasted base and hydrogen generators to suit location (Mercon with SBM as subcontractor)

• Install ocean energy generators, template and flowlines (Technip/others?)

• Mobilise the TOPS ship and drill first well

• In event of dry well redeploy equipment


Financing

• in 1980 TOPS was based on paying the shipowner 20% rate of return on the equity in the original acquisition cost of the reuseable components of the project

• The oilco requires to pay for the lower buoy, the installation work and 90 days of operations

• The leasing partners in TOPS are sought


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)

• Ocean power to generate H2 (Magnomatics/ITM Power)


TOPS Template (FMC)• 4 by 8 on 8’6” centres well slots

• each Christmas tree to incorporate shear and blind rams and 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 to FMC• Advance Energy Systems to crack heavy oil

to C13 and gases as appropriate

• 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 pump technology


TOPS• station keeping by Dp2 with constant

tension mooring winch working at between 70 and 90 tons (Huismann/AXTech)

• Converted Aframax or OBO which can have LNG tanks put in the holds for later life operations (previous model in Eboroil jv m.v.Arctic which was 25,000 dwt)

• Receive oil, gas, water and distribute oil, gas, drill cuttings removal and pigging services


Drilling

• 30” conductors installed on all wells in the construction phase (Technip)

• use 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


Drilling Operations

• Mount Helirig on the Port side of the ship to work in the lee based on heading bow quarter into the weather

• Have top drive and coil for intervention

• Recover and treat drill cuttings with biodegradable oil solvent and dump cuttings

• have slip joint design by Aker accepted by Schlumberger


Thoughts

• Stern into weather towards SALM

• Accommodation at stern

• Shottels bow and stern instead of Becker/other rudders such as Schilling from main engines

• New build

•


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


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


Ship Operations• Have Captain in charge of all operations

• Change crew every three weeks and recharge activated charcoal using the dry evacuation system (GEC)

• 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


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


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 services

• in the arctic amphibious life-boats and infra red satellite based radar to navigate in minimum ice


The First Project

• The Irish Authorities have been approached to develop Barryroe in conjunction with the current Option holders

• All contracts will be at cost plus 20% and there will be no bidding with technical excellence deciding the contract award

• Intend to work with Lloyds Registry and have IOM flag
