UK Gas Supply/Demand Outlook

  • UK : supply gap opened in 2005 as production declines

– Demand growth expected to slow to 2-3%/year to 2010, then levels off – First Qatar LNG imports available starting in Winter 2007/08 UK/Ireland Gas Supply/ Demand

Project Scope

Gas to Pipeline Gas LNG LNG Gas Production Gas Treating & Liquefaction LNG Shipping LNG Regasification $ 13 billion dollar mega-project employing full value chain integration, step-out technologies, and economies of scale to offset distance to market.

  • Gas from world’s largest gas field; 2.8 billion cubic feet per day
  • Two 7.8 million MTA trains will be the largest ever constructed; 60% larger than any to

date

  • A fleet of 14 large LNG ships; at 210 – 265 km3, 70% larger than any ever built
  • Receiving terminal in the U.K. to re-gasify and deliver 2.1 billion cubic feet per day
  • 15- 20% of UK demand

South Hook Terminal Development Plan

Description

  • Upgrade and refurbishment of existing jetty
  • Five 155 km3 full containment LNG storage tanks
  • Two berths
  • Submerged Combustion Vaporizers (SCVs)
  • 2.1 BDFD export
  • Pipeline extension (∼128 km) to national gas grid

to be built and operated by others (NGG)

  • PL grid reinforcement by NGG
  • EPC by Chicago Bridge & Iron
  • Total capex of $1.4 B spent over 2003 – 2009
  • Status
  • Phase 1 currently 65% complete; Phase II 40% complete
  • First gas early 2008

The Environment & South Hook LNG: Jetty

Pipeline Gas

  • Maximise use of existing structure to minimise impact on marine environment
  • Close consultation with DEFRA, EA, CCW, MHPA on management of redundant

structures

  • Careful management of jack-up rig/anchor positioning to minimise impact on eel grass,

red maerl

  • Highly efficient new-build ships to be deployed
  • Efforts to minimise impact on public use of coastal path, small boat passage

The Environment & South Hook LNG – Tanks

Gas

  • Full containment (tank within a tank) structure for maximum integrity
  • Gas kept liquid through effective insulation; no refrigeration requirement
  • 2 million tonnes spoil moved; screening bunds created
  • minimise visual intrusiveness of facility
  • Tanks, though large, were specifically designed to be wider and squatter than normal to

minimise visual impact

SLIDE 11

Gas

  • Two competing technologies: open rack, submerged combustion
  • Open rack
  • Use large quantities of sea-water; impact on marine organisms
  • Pumps/lines require anti-foulants
  • Return water significantly colder
  • Submerged combustion
  • Small quantities of LNG boiled off
  • Used to heat water bath; some CO2 emissions; very high efficiency (98%)
  • Technology choice made in conjunction with key stakeholders
  • Designed to minimise impact of emissions from vapourisers

Pipeline

  • Topography of site presents water drainage challenges
  • Exacerbated by soil disturbance during construction
  • Complex system of hold up ponds developed
  • Existing settlement pond by-passed
  • ‘Silt Buster’ installed
  • Regular monitoring of effluent quality; daily sampling, multiple visual inspections
  • Achieving 30 mg/litre sediment levels (c.f. permitted level of 75 mg/litre)
  • System proved robust even during recent heavy rains

Gas to Pipeline

  • Unique eco-system
  • Legally binding Section 106 Agreement with PCC/PCNPA
  • 110 acres of site made over for nature conservation
  • Management plan under development
  • Steered by site manager + representatives from interest groups
  • Access to area will be controlled
  • Artificial badger sett created
  • Kestrel nesting boxes to be installed shortly

Gas to Pipeline Gas

  • Public consultation a key element of advocacy strategy
  • Visitor Centre
  • Website
  • Leaflets
  • Public/stakeholder meetings
  • Significant engagement with the Media
  • Rolled out Community Funding Initiative in 2006
  • ‘shallow and wide’ strategy
  • Focus on education, health, environment
  • Not a substitute for public funding
  • Focus for 2007 is to develop more self-sustaining initiatives
