Uncertainty Over Pod-Plagued Research Ship
19 Nov 2007
It is uncertain just when Germany’s most modern research ship Maria S. Merian will go back into service now that a series of propulsor problems has left it laid-up and without power in Kiel.
The €56.4 million polar rim specialist, which went into service in April 2006, had to break off research in August and return to Kiel after suffering problems with its Schottel Electric SEP 2 Propulsors. The 2,050 kW units have since been dismounted and returned for repair.
The 94m LOA, 5,300 gt vessel was towed to Kiel’s commercial Ostuferhafen in October. It had earlier spent weeks at Kiel’s Lindenau Schiffswerft before being transferred to the Ostuferhafen when it became clear that repair would take longer than initially thought. The latest word is that it could be next year before the ship returns to service.
Lürssen and Kroeger refused to say anything about the ship’s problems. Manager Briese Schiffahrt and owners BAW also had nothing to say. However Schottel marketing head Kurt Scholz told MJ the difficulties had been caused by propulsor sealing and slip ring transmitter problems.
He reported two instances of sealing damage. The first in April was not caused by any external influences, he said. The second leak, in July, 'Was at the very least made worse, if not actually caused, by operational damage to the propeller by the user', Scholz said. Since then, Schottel and the makers had developed improved sealing and this was now being incorporated as part of the repair, he reported.
Scholz added that the slip ring transmitter problem had 'existed from the very beginning' and that all efforts at repair had failed. The old design was now being replaced by a new design from another maker which would be available at the end of January 2008, he told MJ.
