Control System Retrofit Key To Extending Tug Operational Life

The project was commissioned by Baltic tug operator Alfons Håkans for a newly acquired tug, Dunker. The project, which was undertaken by Steerprop’s Lifecycle Extension Services, is also expected to ensure the reliability of the vessel’s control system.

When Alfons Håkans identified a need to modernise the electrical controls of a newly acquired tug, it commissioned Steerprop to undertake the work. While the tug’s hull and old propulsion units were in good condition mechanically, the tug’s propulsion control system, from control levers to the propulsion internal control system, required modernisation work.

Alfons Håkans, which operates a fleet of tugs, barges and work boats in Finland and the Baltic states, had previously commissioned a similar modernisation project from Steerprop.

“We have worked with Steerprop previously on a similar project, Artemis, and we were very happy with the success of that project. It was natural to approach them regarding modernizing the Dunker as well,” says Tuomas Raumanen, Technical Manager at Alfons Håkans. “Additionally, Steerprop was able to offer several custom-made engineering solutions to fulfill our quite specific operational needs,” Raumanen adds.

To resolve Alfons Hakans’ challenges with out-of-date propulsion control system technology on the Dunker, Steerprop held thorough discussions with the captains and technical personnel of the vessel, gathering direct feedback and requests for various technical features to the updated solution. Close cooperation with the customer enabled Steerprop to engineer a retrofit installation based on a customized scope of Lifecycle Extension Services, which will considerably ease the vessel’s operations in the future.

The delivery will include a state-of-the-art control system for the existing propulsion units, the main propulsion bridge equipment, and a renewed service relationship. The retrofit project is scheduled to take place in autumn 2023. 

Steerprop’s high-quality control system offers a first-class maneuvering experience and high operational reliability, as well as control levers that are equipped with full redundancy, enabling complete follow-up backup control. The system also allows for remote service support via the Steerprop remote service module.

“We are extremely pleased that Alfons Håkans has chosen to strengthen our already excellent cooperation and decided to develop their fleet with us. Nurturing close customer relationships and resolving challenges for, and together with, our customers has always been at the core of our business,” says Esa Peltomaa, Technical Sales Manager at Steerprop.
