Blue Subsea Cable

Archaeological permitting was supported by a geophysical report and underwater archaeological surveys conducted for a major subsea telecommunications deployment project within Cyprus’ Territorial Waters and Exclusive Economic Zone (EEZ).

main objective

AI MSS was entrusted to secure archaeological/heritage permitting and project consensus from the relevant national custodian heritage agency, namely the Department of Antiquities of Cyprus (DoA), through ensuring that the proposed cable rote of the Blue Subsea Cable (BSC), will not affect any “known and unknown archaeological sites” in the area.

 

To fulfill this mandate, AI MSS undertook a comprehensive Geophysical Archaeological Impact Assessment (GAIA), covering the entire proposed route, from the designated proposed landing point in Cyprus to the outer boundaries of the country’s Exclusive Economic Zone (EEZ), through implementing a dual-method approach:

  • Archaeological dive surveys were conducted in the shallow nearshore waters, and
  • Geophysical data analysis of the deeper offshore sections of the route.

 

The assessment was consolidated into an overarching report, composed of five specialised sub-reports, each of which received archaeological permitting without further comments from the DoA, demonstrating the quality and thoroughness of our methodology.

scope of work

  • Archaeological permitting
  • Full route cable analysis
  • Geophysical data analysis
  • Dual-method investigation:
    • Nearshore archaeological dive surveys
    • Offshore geophysical data analysis

methodology

  • Assessment Methods
    • Dive Surveys: Shallow water investigations (Yeroskipou to ~46m depth)
    • Geophysical Analysis: SSS, MBES, MAG, SBP datasets across deep-water route to 2710m and onward to the EEZ
  • Reporting Structure
    AI MSS produced five specialised reports:
    • A24 Nearshore Report – Dive surveys from Yeroskipou to ~46m
    • A24 Deep-Water Report – From ~46m to ~2710m (Branching Unit)
    • A23 Deep-Water Report – Parallel deep-water assessment
    • A25 Deep-Water Report – From Branching Unit to Cyprus EEZ boundary (toward Israel EEZ)
    • A24 Dive Survey Report – Supplementary nearshore analysis with photographic and mapped insights

outcome & highlights

  • All reports approved without comment by the DoA
  • Demonstrated regulatory precision, data integrity, and archaeological diligence
  • Provided Meta with permitting assurance for cross-border cable deployment
  • Successfully managed multi-phase reporting and cross-zone compliance in a single permitting cycle
