Seatools

Seatools debuted its patented seabed pre-cutting and clearance technology, Iron Bull, a tool designed to miti- gate risks posed by adverse soil conditions and subsurface obstacles, offering Offshore Wind Farm (OWF) develop- ers and contractors signi? cant reductions in both risks and costs during offshore cable installation operations. The technology removes all subsurface objects, such as boulders and obsolete cables, that could obstruct cable laying and burial operations. Additionally, it loosens the soil through pre-cutting with unique drum cutting technology. By fully clearing and loosening the cable trajectory over a 4-meter
