About the Cableship Codex

Your Guide to the Global Cable Ship Fleet

The Cableship Codex is a meticulously researched reference providing a comprehensive view of the vessels that install, maintain, repair, and support the world's submarine cable infrastructure. More than a vessel directory, it combines verified ship specifications, AIS-derived activity analysis, geospatial mapping, and operational insights to reveal how the global cable fleet is deployed. Designed for industry professionals, researchers, and maritime stakeholders, the Codex delivers a structured understanding of the ships that keep the world's subsea communications networks operational.

How the Codex is Created

Our data-driven methodology combines AIS-derived vessel tracking, geospatial analysis, vessel specification research, and industry expertise to create a structured view of the global cable ship fleet. Vessel activity is analyzed using ArcGIS Pro to identify operational patterns, regional deployment trends, and areas of concentrated activity. Through continuous data validation, normalization, and fleet monitoring, the Cableship Codex delivers accurate, consistent, and actionable intelligence on the vessels supporting the world's submarine communications infrastructure.
