Altera Render (26)

In collaboration with Subsea Cable Assets (SCA) and Enersea BV, we have the pleasure of designing and delivering a fully integrated cable lay spread for N-Sea Group’s new cable-laying vessel, Altera 🌟

Combining expertise from four partners, this project delivers a customised deck spread solution optimised for offshore cable-laying operations.

Our contribution includes:

➡️ A 3T vertical loading tower tensioner
➡️ A 15T main deck tensioner featuring breakback functionality
➡️ Quadrant handling solution
➡️ Carousel Drive system
➡️ Cable lay control system

The result is a turnkey system designed to enhance operational efficiency, ensure safety, and engineered to meet the demands of modern offshore wind cable installation and repairs.
