Modular, precision-machined cable carousels for cable lay vessels and barges. Four electric-drive packages (2,500, 3,000, 7,000 and 9,000 MT), engineered and fabricated in Singapore.
Every build shares the same modular, precision-machined structure and synchronised variable-frequency drive. Choose by storage capacity and installation: topside on deck or barge, or underdeck in a newbuild.
Mid-capacity, vessel-of-opportunity package for any suitable MPSV / OCV.
Below-deck carousel with integrated spooling arm for top-loading.
Full spread with containerised loading tower, 2 MT LCE and cable highway.
