The RACK has been designed by SEA srl technical department to perform Post trenching works on pipelines in shallow water areas where naval means cannot, avoiding mooring issues.
The RACK is a tubular frame that can carry the load of a regular PTM and lead it during the trenching operation. The RACK can operate on sand rocky or coral seabeds, moving from the beach area up to a water depth of -4 meters (in good marine conditions).
