10000 VSchleifring (IC 81W)Motors for ships, offshore platforms and other marine applications

Maßgeschneiderter 10.000V Elektromotor mit RINA-Zertifizierung

Individuelle Motorenlösung mit RINA-Zertifikat: Maßgeschneiderte Technik für enge Einbauverhältnisse

Unser Kunde stand vor der Aufgabe, einen 10.000 V Ballastpumpen-Motor zu ersetzen, der in einem stark begrenzten Einbauraum auf einem der größten Kranschiffe der Welt eingesetzt werden musste. Die Anforderungen an das Projekt waren:

  • Austauschbarkeit des Motors: Der neue Pumpenmotor musste exakt in die bestehende Anlage passen.
  • RINA-Zertifizierung: Die Einhaltung der strengen Schiffszulassungsrichtlinien war zwingend erforderlich.
  • Kompakte Bauweise: Aufgrund der beengten Platzverhältnisse war eine exakte Nachbildung der bisherigen Motorabmessungen notwendig.
  • Doppelter Hauptklemmenkasten: Die Flexibilität der Anschlüsse musste gewährleistet sein, um den Motor sowohl mit links- als auch mit rechtsseitiger MTB-Position nutzen zu können.
  • Spezielle Isolatoren: Die Platzierung und Ausführung der Isolatoren im Hauptklemmenkasten mussten identisch zum alten Modell sein.
  • Kabeleinführung: Die Einführung der Kabel musste exakt auf die vorgegebene Position abgestimmt werden.

MENZEL: Manufacturer of customized Marine and Ship Motors

MENZEL is a global manufacturer of large electric motors. We offer customized motor solutions that are precisely tailored to the respective application. Our highly skilled team can professionally adapt the size, power, and cooling of the motors. We have been doing this for almost 100 years. 

In the marine industry and on ships, MENZEL electric motors are used for a wide variety of applications: as main and auxiliary drives (propulsion motors), to drive bow thrusters or side thrusters, for generators, crane systems, compressors, or pumps. 

Use and requirements for the electric drive of a ballast pump on a crane ship

A ballast pump on a crane ship is used to regulate the ballast water system. The ballast water is used to control the stability and trim of the ship - especially during heavy lifting operations with the crane. By selectively filling or emptying the ballast tanks with the help of the pumps, the ship can be balanced and kept stable to enable safe working conditions.

What criteria must the electric drive of a ballast pump on a crane ship meet? 

It must:

  • be designed for continuous operation (24/7)
  • have a sufficiently high rated power to operate the pump reliably even under high loads
  • meet the requirements of RINA, DNV, or other classification societies
  • have protection classes such as IP55 or higher to be protected against water and moisture
  • withstand extreme temperatures, vibrations, and corrosion

About the third most powerful floating crane and one of the largest working vessels in the world

The crane vessel supplied by MENZEL is designed for laying pipelines in deep water and for heavy lifting work in offshore construction and energy projects. It is self-propelled and has a semi-submersible body. 

The vessel has an advanced ballast system with four 6,000 m³/h ballast pumps, 40 ballast tanks, and 14 fast ballast tanks, which ensure efficient stability adjustment during operation.

Marine certification and RINA approval: safety and quality for marine motors

Marine certification such as RINA plays a key role in ensuring the safety and efficiency of marine motors in international maritime transport. It ensures that electric motors meet the technical and safety requirements of a recognized classification society. 

RINA approval refers to the certification and classification of ships and their components by the Registro Italiano Navale (RINA). RINA is an internationally recognized classification society based in Genoa, Italy. RINA approval certifies that our motors comply with international standards, are safely designed, and can be operated without risk. 

Advantages of RINA-certified marine motors

  • Safety: Prevents accidents through tested design and operational safety.
  • Environmental protection: Minimizes emissions and ecological risks.
  • Operational efficiency and reliability: Optimizes motor performance and service life.
  • By adhering to strict RINA testing criteria, our buyers and operators of large ships benefit from the highest level of safety, reliability, and efficiency of our electric engines.

MENZEL Motors testing service in our in-house load test facility

MENZEL Elektromotoren operates its own load testing facility at its Hennigsdorf site near Berlin, Germany. In our in-house test field, we offer comprehensive testing services for routine, type, and system tests - also for external clients and brands. 

The most important internationally recognized classification societies for marine inspections that can be carried out at our test facility include:

  • DIN EN 60034
  • Measurements according to energy efficiency classifications IE3, IE4, and IE5
  • Bureau Veritas - BV
  • Lloyd's Register - LR
  • American Bureau of Shipping - ABS
  • Det Norske Veritas - DNV
  • Registro Italiano Navale - RINA

 

Each classification society has its own areas of focus and strengths. The choice often depends on the ship's flag, its area of operation, and specific technical requirements.
