By modernising the system, Steerprop also provided a capability for remote service diagnostics.
Future-proofing a vessel in nine days Back in 2019, the technical department at Alfons Hakans noticed a need to modernise and upgrade the propulsion control system on its Azimuth Stern Drive tug Artemis. It was no longer possible to get spare parts for its original control system; and although it was still reliable, for safety reasons the company decided to look for reasonable solutions for a full-scale upgrade.

“W

minimum. To decrease the amount of downtime, Hakans’ own workers and subcontractors started preliminary works, such as installing new cables and manufacturing foundations for electric cabinets, whilst the tug was still operating normally. Meanwhile, Steerprop was building the entire control system at their workshop. “This way the installation time onboard would be as short as possible”, Mr Raumanen says. The installation began at the end of
