The Carrera 4 is a multi-purpose excavation tool, ideally suited for accurate trenching, (de)burial, stabilisation and/or excavation of seabed materials. It can perform in a range of soils including clays and sands, whilst the width of the tool is adjustable so that the trench width can be varied during operation. Variable output modes with full positional control provide flexibility and high precision, making the Carrera 4 an ideal tool for trenching or excavationworks at cable-end locations which are in close proximity to offshore turbine/platform structures.
