Towage operator Svitzer has begun sea trials of a remotely operated line catching technology prototype. The system reduces risks for crews during the process of connecting with other vessels, one of the most critical elements of towage operations.
Connecting heaving lines at sea presents significant risk to crews, particularly from a centre lead forward position where the tugs must operate very close to the connecting vessel. This is further influenced by other factors including wind, sea state, and the increasing size of vessels, where the distance from the tug is significantly greater and requires more accurate throwing.
Svitzer’s new prototype line catcher mitigates these risks as it is remotely and safely operated from the wheelhouse and catches and secures the connecting vessel’s heaving line. With a wingspan of between six and seven metres when activated, the crew on the connecting vessel has a larger target area to hit with the heaving line weight, and no member of the tug’s crew is exposed during the process. The automated catching arm prototype is also designed to increase the success rate of connecting the vessel to the tug, leading to safer and more efficient operations.
Line Handler Technology
The line handler consists of a hydraulically controlled set of catching arms, fitted on the foredeck of the tug. It includes an automated tying mechanism that connects the heaving line with the tug’s rope line in a safe and efficient manner.
The catching arms and the tying mechanism are remotely operated from the bridge. It has a wingspan of six to seven metres in the air above the foredeck of the tug when activated. An automated tying mechanism connects the heaving line with the tug’s rope line in a safe and efficient manner. The line catcher allows crews to use adequately weighted lines without risk to tug boat personnel.
Live Testing
Svitzer’s technical team in Copenhagen has been developing the remote line handling technology for the past year. It will now be installed and tested over the coming months on the Svitzer Trym in the company’s Scandinavian fleet to prove the concept. This will include documenting and analysing performance in a live operational environment and recording how the technology is impacted by weather and other factors so that potential improvements can be made to further enhance safety and efficiency.
The testing process will also define clear requirements and standards that will need to be implemented for the training of crews in effectively and safely operating the remote line catcher.
The installation is being conducted in consultation with and with final approval from Lloyd’s Register.
