Asset Protection Technology

TekDuct

TekDuct is Tekmar’s engineered impact and abrasion protection solution designed to safeguard subsea power cables, umbilicals, risers and flowlines (SURF) throughout installation and operational life. Developed to perform in harsh offshore environments, TekDuct helps protect exposed subsea assets from mechanical stress, abrasion, crossing damage and dynamic seabed conditions while supporting long-term asset reliability.

Proven subsea protection technology for offshore wind, oil & gas and critical offshore infrastructure.

Designed to closely match cable and pipeline profiles, TekDuct can provide additional ballast and on-bottom stability while supporting bundled cable protection where required. Its modular, lightweight construction simplifies handling and offshore installation, helping customers improve efficiency while reducing operational complexity across offshore wind, oil and gas, interconnector and marine infrastructure projects.

Key Features

  • Engineered impact and abrasion protection for subsea power cables, umbilicals, risers and flowlines (SURF)
  • Helps protect assets from external impact, mechanical stress and harsh seabed conditions
  • Designed for cable and pipeline crossings and subsea separation requirements
  • Provides additional ballast and on-bottom stability support where required
  • Suitable for bundled cable and subsea asset protection applications
  • Modular two-piece half-shell design for simplified handling and installation
  • Designed to integrate with cable protection systems, bend restrictors and J-Tube sealing systems
  • Configured to closely match cable and pipeline diameters for reliable fit and performance

Applications

TekDuct supports a wide range of offshore infrastructure applications, including:

  • Offshore wind export and inter-array cable systems
  • Oil and gas pipelines, risers, umbilicals and SURF infrastructure
  • Cable and pipeline crossing protection
  • Interconnector and subsea power transmission projects
  • Fibre optic and communications cable infrastructure
  • Marine infrastructure and subsea stabilisation applications

Proven Track Record

TekDuct has been successfully deployed across offshore wind and oil & gas projects worldwide, supporting the long-term protection and performance of critical subsea infrastructure in challenging offshore environments.

Representative projects include:

  • Ivar Aasen
  • West Brae
  • Caithness Moray
  • Badamyar
  • Wave Hub
  • Lake Huron subsea infrastructure
