Off to a quick start…
Having successfully completed the advanced training program, all E-Crane certified crane operators familiarized themselves within an hour with the new E-Crane’s systems. After this brief introduction operators assisted with the soft loading of dark bulk material (iron ore oxide) into a large handy class vessel (shore-to-ship operation). This first job was completed swiftly and with great comfort so it was time to move to the next and more demanding job: offloading zinc concentrate from a coaster into the existing dockside travelling hopper (ship-to-shore operation).
Efficiency and Productivity go Hand in Hand
Immediately after the offloading of zinc concentrate into the 14 meter (!) high hopper started, cycle times in a 40 to 45 seconds window were observed. Using the 7,5 m3 grab this resulted in a net payload of zinc concentrate between 14 and 16 tons (!) and peak offloading capacities in the 1150 to 1300 tons per hour range. As the operators’ skills with this new piece of equipment will certainly further improve and as dock management will gain experience and know-how with the logistics up and around the E-Crane, all involved in this new and exciting project are convinced that the E-Crane will contribute to the further successful development of Kokkola’s Deep Port activities and the long-term profitability of the port.
At E-Crane State-of-the-art technology simplifies the operation and maintenance of complex equipment
The operators also extensively tested the ‘semi-automatic offloading’ option of the crane because the ship-to-hopper operation is a perfect application for this feature. Rather quickly it showed that the use of the semi-automatic cycle option resulted in improved operator comfort combined with good cycle times. However, and this was no surprise, the experienced crane driver could still out-perform the crane’s computer systems. In order to greatly increase serviceability, POK’s E-Crane has remote connectivity (tele-servicing) capabilities and this means that E-Crane service engineers can remotely connect from around the world to trouble-shoot, resolve problems, assist with the repairs of the crane and provide the necessary support during regular service intervals without having to travel to the job-site.
E-Crane would like to use this opportunity to pay a tribute to the dedicated work by and excellent cooperation with the staff of the Port of Kokkola during many technical meetings, during the dock-side installation, during the commissioning process, the testing, tuning and start-up of the crane and finally during the commissioning phase.
For all who have spent day and night in turning this exciting project into a success, this work has also been an opportunity to get to know each other better and build close personal ties. E-Crane particularly congratulates Mr. Torbjörn Witting, Port Director, and Mr. Tapio Lampinen, Technical Manager, and their team for the support and hard work and we wish them fair winds and following seas with this new E-Crane.
