Zero-emission crew transfer vessel operations

ScottishPower Renewables is part of the Iberdrola Group, one of the world’s largest integrated utility companies and a world leader in wind energy. ScottishPower Renewables is at the forefront of the development of the renewables industry through pioneering ideas, forward-thinking and outstanding innovation.  Its ambitious growth plans include expansion of its existing onshore wind portfolio, investment in new large-scale hydrogen fuel technologies and innovative grid-storage systems including batteries. The company is also delivering the Iberdrola Group’s offshore windfarms in the Southern North Sea off East Anglia within others.

Challenge Background

 

Cost of zero-emissions vessels has been identified as an early barrier to their deployment in the offshore wind industry. ScottishPower Renewables is interested in measures to reduce costs and enable their usage in the sector, for example:

  • Usage of power generated directly from the offshore wind farm
  • Hydrogen produced at the offshore wind farm
  • Other alternative fuels.

In 2018 the International Maritime Organisation (IMO) released their ‘Initial IMO Strategy for Reducing GHG Emissions from Ships’. This strategy aims to halve emissions from international shipping by 2050, and reduce carbon intensity by 40% by 2030, and 70% by 2050.

The ‘Initial Strategy’ sets out short-, mid-, and long-term measures. In the list of identified candidate short-term measures, the IMO includes promoting the uptake of alternative low-carbon and zero-carbon fuels and providing shore-side electricity.

As part of the ‘Initial Strategy’ it is envisaged that market-based measures will be used to incentivise the decarbonisation of shipping. Market-based measures may be used to discourage the use of high-carbon fuels e.g. through the use of carbon taxes, and to encourage the adoption of low-carbon practices through incentive mechanisms.

As a committed company in the green energy industry, ScottishPower Renewables would like to be at the forefront of this step-change as early adopters of alternative low-carbon and zero-carbon crew transfer vessel operations.

ScottishPower Renewables is looking for any solution that has the potential to enable zero-emissions Crew Transfer Vessel (CTV) operations without impacting on our operating requirements (below). Solutions can include. Solutions could include:

  • CTV concepts that produce zero-emissions
  • Technologies to facilitate the recharging or re-fuelling of vessels either on-site at the windfarm, or at shore/port.
  • Alternative fuels able to be retrofitted/used in existing CTVs

Other technologies enabling a step-change reduction in the emissions of CTVs.

Solution Requirements

Functional requirements

Since many new vessel powertrains or CTV concepts are subject to rapidly advancing technology, proposed solutions must be designed such that they can accommodate future upgrades to reflect state of the art technology, or so that complete replacements will be possible.

Considerations must be made for:

  • Safe storage and handling of any fuels
  • Safe operation of the vessel
  • Safe operations for the vessel’s crew, including whether there are differing needs for hazard awareness or competencies
  • Safety if the vessel is involved in a major incident including (but not limited to): fire, collision, allision or grounding
  • Risk profile of operations

Additional considerations for CTV concepts:

  • Vessels must be able to achieve a minimum transit speed of 22 knots and have the endurance to remain in service for a minimum of 14 hours and safely perform transfers up to a significant wave height of 1.75m.
  • Future operations for CTVs will require greater transit distances and so higher transit speeds will be necessary. In order for CTVs to be a viable option for more distant sites the vessels should be capable of 30 knots without major increases in power consumption.

Additional considerations for alternative fuels:

  • CTVs using alternative fuels must be able to operate to a similar standard as current conventionally fuelled CTVs but have the capacity to increase their operational capability in the future as OWFs move further offshore.

Additional considerations for battery, or hybrid systems:

  • Batteries must be capable of trickle charging overnight, but also capable of charging depleted batteries to 80% capacity within 90 minutes (Bolt Charging/Rapid Charging). The vessel would also need to be capable of making use of offshore charging technologies using energy generated directly by the offshore wind farm. These charging methods are currently in development.
  • The battery hybrid system needs to be intelligent and optimised to best augment the diesel engine. Which stage of the operation is the hybrid system best utilised? E.g. transit, farm idle etc.
  • Additional considerations for hydrogen systems
    • Vessel must be capable of bunkering sufficient hydrogen to remain in service for a minimum of 14 hours and be capable of bunkering fully within 45 minutes.

Timescales

  • Launch of the Competition: 15th November 2021
  • Deadline for applications: 15th December 2021
  • Selection and notification of finalists: week commencing 10th January 2022
  • Pitch event: 8th February
  • Launch Academy begins end of February 2022

Market opportunity

According to a roadmap produced by ORE Catapult with the Workboat Association on behalf of Department for Transport, there will be a requirement for 249 O&M vessels to serve 166 windfarms in the North Sea basin by 2025. By 2030, this requirement will rise to 455 vessels as the expansion of offshore wind continues.
