IFA2 - Survey Works
Published 22:00 on 6 Aug 2020
What is IFA2?
Remember IFA2 (Interconnexion France-Angleterre 2), the project to provide an electrical connection between Normandy and Fareham. The High-voltage direct current (HVDC) cable from France comes ashore at Hill Head and connects to a converter station on Solent Airport. High-voltage alternating current (HVAC) cables run from the converter station back to the Solent and along the seabed to make a landfall at Brownwich. From there they go underground to a new substation at the National Grid site off Chilling Lane near Warsash.
You may recall that in 2018 the IFA2 Project surveyed the HVAC route then carried out "boulder" removal. Last year, 2019, the HVAC cables were laid between July and August. The less intrusive (for us) burying phase went on for another couple of months.
The IFA2 Project have just started a final as-laid survey of both DC and AC cable routes in the nearshore area. This work will take place along the cable routes shown in purple (HVAC) and blue (HVDC) in the picture above. Work started on Wednesday 5 August and should be completed by 18 August 2020.
The survey works are being carried out using TSM OUESSANT (IMO 9899387; MMSI 228387800; Call Sign FLZM) & Coastal Observer (MMSI: 232025120; Call Sign: MGIQ9). Both vessels will work independently, and each will move very slowly back and forth along sections of cable route to complete their work.
Please pass at a safe speed and distance. Vessels are advised to remain a safe distance (approximately 500m) from the areas identified. During these works the vessels will have restricted manoeuvrability as they complete the surveys. The vessels will monitor VHF Channel 16 at all times.
