Status, benefits and challenges of Electrification by Power from Shore

Trygve Iversen, ABB AS – OGP, 2010-03-16, Bellona Seminar


Electrification

Advocate and develop economical and HSE sensitive solutions for offshore installations

How

Studies /feasibility

Electrification (power from shore)

Automation

Remote Diagnostics/Condition based maintenance

Maximize technology utilization to minimize OPEX by moving the personnel on-shore

Concept Super Grid


Supergrid concept (Vision) Main concept, combine:

Integration of renewable energy

Interconnections for trading

Security of supply

Benefits

Reduced investment

Increased trading capacity

Back-up power, e.g. hydro power can support wind power

Large geographic area gives more stable production


WG Offshore grid

Vision 2020 – an offshore grid enabling

Offshore wind parks

Power supply to oil fields

Energy exchange between markets

Ancillary services (freq control ++)

Task

Describe technology status

Describe ambitions towards an off shore grid

Describe R&D challenges


Opportunities and ChallengesOpportunities:

Technology is available, no significant technology gaps

More compact HVDC solutions possible (reduced installed costs, 2 years to develop)

Challenges:

Time (not long until 2020)

Projects take time, typically 5-8 years from concept to operation

Get started!!!

Production limits

Cables

Build additional production lines (3-5 years)

Engineering resources

Limited supply of qualified engineers

Shift resources from other areas (2-4 years)
