The Rotterdam based shipping company Rotortug and ASD Ship Design from Alblasserdam have invented a revolutionary tugboat technology (‘tugnology’) to prevent towline failures from chafing against a tugboats fixed towing point. Conventional towing point designs are usually fixed bitts fitted with polished and stainless steel cladding in line contact areas guiding a towline to a towing winch. Using state of the art towing winches, towlines are winched in and out automatically by using a pre‐set line force to prevent both dynamic overloads and slack wires.
