Taihan Cable Teams with Robotics Firm to Build Subsea Installation ROVs

Taihan Cable partnered with a specialized marine robotics firm to develop domestic remotely operated vehicles for underwater power network installations. The project aims to eliminate reliance on foreign equipment suppliers across offshore grid contracts.

Developing dedicated subsea machinery in-house gives the South Korean manufacturer direct control over offshore laying schedules and operating costs. Specialized subsea trenching and burial vehicles remain critical bottlenecks in regional power grid deployments, where contractor shortages routinely delay cable commissioning.

Cutting Dependence on Foreign Marine Tech

The joint engineering effort focuses on building specialized subsea remotely operated vehicles capable of handling deepwater cable laying, seabed trenching, and cable protection tasks. Most Asian grid developers currently lease or purchase heavy marine robotics from a small group of European and North American specialists.

Localizing this machinery allows the company to bid on turnkey offshore wind and interconnector jobs without exposing project timelines to overseas equipment availability. The company said the project will sharpen its construction competitiveness as it targets large-scale contracts in the global power infrastructure market.

Offshore Power Grid Expansion

Offshore wind expansion across East Asia has triggered a race among regional cable makers to secure dedicated installation vessels and underwater trenching tools. Rival Asian manufacturers have made similar investments to vertically integrate their offshore installation divisions.

Commercial rollout timelines for the newly developed subsea vehicles and their initial deployment sites will determine how quickly the group can challenge established European installation contractors in regional waters.
