Increasing security of electricity supplies for both the UK and France.

Onshore cables

  1. The HVAC and HVDC cables related to the converter station will make landfall at Monk’s Hill beach.
  2. We will lay HVDC and HVAC cables to and from the converter station along one of the runways at Solent Airport. We’ll start this work in October 2018 and finish in October 2019.
  3. The HVAC cables will run along the bottom of the Solent to Chilling. We’ll lay these in 2019.
  4. The HVAC cables will make landfall at Chilling.
  5. We will lay HVAC cables between the landfall and connection point at Chilling. We’re carrying out construction work here until September 2018, and then installing the cables in 2019.
  6. The HVAC cables will connect to the national electricity transmission system at a substation in Chilling.

Airfield

Our HVAC and HVDC cables will connect to the Converter Station, the route from Monks Hill Beach to the Converter Station involves the installation of the cables onto Solent Airport.

Work on the airfield during 2018 and early 2019 involved excavation of trenches and joint bays, installation of ducts for the cables in the trenches, backfilling and reinstatement. Installation of the cables and jointing works will follow on from this work during spring and summer of 2019.

In October 2017, National Grid IFA2 undertook EMF trials on Solent airport. Using AC and DC cable systems installed and energised in the configuration and current rating reflecting the actual conditions in service. This was to verify compliance with the planning conditions and that there was no interference with aircraft avionics.

All participants, including airfield users confirmed that:

  • During the trials all aircraft systems functioned as normal
  • There were no anomalies observed on any of the aircraft avionics
  • Magnetic compass deviation was temporary and minor
  • For more information on Solent Airport please visit www.solentairport.co.uk

What are we doing in the next three months?

  • We have finished laying the offshore HVAC cables and are now burying them. 
  • The HVDC cable has been positioned in the pre-prepared trench off Monks Hill Beach and we are now burying the cable and reinstating the sea bed.

Monks Hill Beach

This is where both the HVAC and HVDC cables will come onshore. All work will take place within a compound in the eastern part of the car park. We’ll access this using a purpose-built haul road through a field to the north of the car park. This will mean full public access to the western part of the car park; the beach and the beach huts are preserved throughout the construction period.

Our work will consist of the excavation of trenches to install the cable ducts, backfilling and reinstatement and the construction of 3 transition joint bays in the car park which will be backfilled and reinstated after completion of the jointing works.

When carrying out this work we will:

  • Ensure the working areas are safely segregated from the public
  • Complete the beach works and work within the eastern car park area within one season (2019)
  • Maintain access to the western section of the car park ensuring that access to all beach huts is maintained.

 

What are we doing in the next three months?

  • Our excavation and trenching work on Monks Hill Beach is complete and we have reinstated the beach.
  • We are burying the six HVAC cables between Monk’s Hill Beach and Chilling and our vessel, the CAPALL MARA, is active in the area. We expect to complete this work in November.
  • We have site hoardings around the area to the south of Crofton Avenue which is the main access for our construction traffic down to Monks Hill Car Park.
  • We are working on cable jointing and burial at Monks Hill Car Park behind the site hoardings. We will maintain the footpath access from east to west while this work is ongoing.
  • The current position of our vessels can be tracked on the MarineTraffic.com tool on the Offshore Cable section of this site.

Chilling

Chilling is the point that IFA2 will connect to the electricity transmission network. We are laying cables from the shore area to an existing National Grid facility on Chilling Lane.

We have used a technique known as Horizontal Direct Drilling (HDD) to install cables in the shore area. This involves drilling underground and installing a series of ducts, which we then pull the cables through.

Elsewhere, we will dig trenches, bury the ducts, reinstate the ground, and pull the cables through. In all cases, the cables will not be visible when we have finished. For further information on NGET and the work at Chilling please visit: https://www.nationalgridet.com/infrastructure-projects/ifa-2-connection 

To reduce the impact of our project traffic in the area we will do the following:

  • Impose a 10mph speed limit for construction vehicles through Hook Village
  • Escort any HGVs moving through Hook Village
  • Brief drivers about Chilling Lane’s use as a footpath and cycleway

What are we doing in the next three months?

  • We have now completed work and reinstatement for this year in the Chilling area.
  • Due to bad weather and poor ground conditions we will need to return in Spring 2020 to complete a small amount of reinstatement.
  • We will not be mobilising a full site and will keep equipment to a minimum to complete this final work.

    IFA2 looks to the skies to enhance safety

    IFA2 has worked with Daedalus-based company Flylogix on the development of an innovative solution for the coordination of offshore safety.

    IFA2 has worked with Daedalus-based company Flylogix on the development of an innovative solution for the coordination of offshore safety. The local technology and aviation business carried out Unmanned Aerial Vehicle (UAV) operations over the congested waters of the Solent and the Channel. Its mission was to provide live video of cable installation to help coordinate safety operations on the water.

    The UAV in the air

    Jake Stevens, IFA2 project manager, said: “We are laying interconnector cables in one of the most congested marine and aviation areas in the UK. In order for the works to be performed safely and minimise disruption we have looked at developing an innovative solution to help manage offshore operations.

    “To further support our safety vessels for this operation we have also worked with Flylogix, here on Solent Airfield, to include aviation and add a further dimension to our safety solution. Our aim was to develop a UAV real time image system to increase the monitoring of vessel traffic in area and to help ensure that the project can be completed without incident to the public or commercial water users.

    “We know that working with local businesses, such as Flylogix, can bring benefits to the project and also to the community. We were very pleased to be able to source the specialist expertise we needed right here in Lee-on-the-Solent.”

    Chris Tavner, Flylogix and Adrian Morris, IFA2

    Ed Clay, Flylogix's Operations Director, said: “The Solent is one of the busiest stretches of water around the UK with the convergence of heavy commercial, freight, leisure and fishing vessels coupled with challenging navigational features. The addition of our UAV surveillance capability further bolstered an already comprehensive maritime management operation for the IFA2 interconnector project.”
