Ship propellers at full speed

Mecklenburger Metallguss MMG, Waren an der Müritz, is benefiting from stricter environmental legislation in the production of its efficient ship propellers.

"We will scratch the 100 million euro turnover mark this year," said MMG managing director Lars Greitsch at the beginning of August during a visit by Mecklenburg-Western Pomerania's state chancellery head Patrick Dahlemann (SPD). This would be the second-best result since 2015 for the company, which manufactures propellers weighing up to 110 tonnes and with a diameter of more than ten metres. In 2022, turnover was 69 million euros.

"The business situation is so good because shipping companies worldwide are under pressure to reduce energy costs and CO2 emissions," Greitsch adds. Because of the consumption, ships today run slower than in the past. The MMG engineers therefore adapted the new propellers and drive parts exactly to the motorisation of the ships. MMG has 200 employees, produces between 70 and 90 propellers per year with a high copper content and has also entered the aluminium casting business. 95 per cent of the propellers are exported, mainly to Asia.
