MARIA S. MERIAN
Research vessel prepared for supply trip to Polarstern
The 'Sonne' and the 'Maria S. Merian' are actually being fitted out at the Lloyd Yard in Bremerhaven and due to start towards the research vessel 'Polarstern' on May 18 to supply the scientists and crew in the Arctic Ocean. They will have on board equipment, food and replacement crew. Initially the 'Polarstern' was to be supplied by icebreakers and aircraft, but as many ports and airports in the region have been closed due to the corona pandmic, it became impossible to stick to this plan. The 'Polarstern' will leave its ice floe and meet the vessels at the ice barrier where the exchange takes place.
Research vessel infringed Finnish territorial waters
The "Maria S. Merian" was suspected of having infringed the Finnish territorial waters on March 10, 2017. The suspected violation occurred around midnight in the Åland sea. The case was in fact no drama, but it was quite a rare event. The Cpast Guard launched an investigation.
Never ending costly pod trouble held research ship in Bremerhaven since months
The "Maria S. Merian" is docked at MWB Shipyard in Bremerhaven since 57 days for work on her Schottel drives after Berlin revealed she had cost €500,000 in repairs and lost 588 days work since she entered service eight years ago. The ship has been bedevilled by pod defects since she was completed by Kroeger Werft on a Polish hull in 2006 at a cost of €56.4 million. Installed was a main propulsion plant consisting of two Schottel electric propulsors Type SEP 2 of 2050kW with propeller diameters of 2,500mm developing 15 knots. A Schottel Pump-Jet Type SPJ 320 of 2,200kW max was also installed as auxiliary propulsion and the ship has a Schottel SST 900 steering system. The "Maria S Merian" docked at MWB in Bremerhaven on Aug 16, 2014, for the latest repairs after developing swivel bearing and other problems in her pod drives. The work, being carried out by German Dry Docks (GDD), has already lasted some three months and there was no word on how much longer she would remain out of operation. After questions were asked in Parliament about the repair-prone ship, the Ministry of Education and Research has revealed that the "Maria S. Merian" suffered 10 serious technical break-downs in her pod propulsion system prior to the latest repairs at GDD. Deficiencies in sealing, pod drive operation and swivel-bearing problems had been among the most prominent issues. According to the Ministry, the repairs had cost a total of about €500,000 and had meant yard stays of five to 189 days. The ship had been out of commission for a total of 588 days since commissioning in 2006, it added. Asked what the Government proposed to do about the situation, the Ministry said it was waiting for completion of a report on whether modifications should be made to the ship's propulsion system or to her maintenance and overhaul schedules. Findings will also be significant for the selection of drive systems chosen for future research ships, the Ministry said.Upload News
