The package includes a SISHIP eSiPOD pro- pulsion system as well as a power and distribution vibration operation of the propeller motors make plant. This new cruise ship to be delivered in the them particularly suited for the high demands of summer of 2019 will be 236 meters long and 31.2 the customers in the yacht, passenger and cruise meters wide with a gross tonnage (GT) of 56,850 ship segment. The reliable power supply of the ship and will offer capacity of 999 passengers. The is guaranteed by the integrated power plant system
Siship Power MV. This comprises four generators contract includes an option to equip one additional with a total electrical output of 21 megawatts. The cruise liner potentially due for delivery in 2021.
According to Siemens, the major bene? t of the NxAIR medium-voltage switchgear takes care of ef? cient and safe power distribution. The power
SISHIP eSiPOD is its high overall ef? ciency re- and propulsion plant is internally controlled and sulting from the combination of a compact, hy- drodynamically optimized design and an ef? cient monitored by the Siemens integrated protection systems such as the Power Plant Protection (PPP), permanent-excited synchronous motor. The pro-
Generator Power Adaption System (GPA) and pulsion motor is integrated into a pod shaped hous- ing located outside the ship’s hull and enables full Propulsion Control System (PCS). www.siemens.com 360 degree steering angle. With the combination
ZF Extends Transmission Range
ZF Marine unveiled the new ZF 83700 transmission equipped with COMOS condition monitor- ing at the SMM 2016. The new transmission supplants the ZF 63000 as the largest, most power- ful transmission in the family, and is designed for high speed vessel applications. The ZF 83700 is a non-reversing twin shaft con? guration offering both live and clutchable PTO’s as well as a clutchable PTI for ? exibility in drivetrain applications. Ratios from 2.412 to 5.591 mean this new transmission family can meet the performance envelope to match most applications. The
ZF 83700 comes standard with technology that provides immediate, smooth clutch engagement.
Designed by ZF for large stationary wind turbine gearboxes, the COMOS condition monitoring is an example of technology sharing within the organization, as COMOS has been adapted by ZF
Marine’s engineering team to meet the needs and requirements of the commercial marine duty cycle. Standard monitoring of transmission systems include normal functions such as oil level and pressure, but also include: input shaft speed, clutch monitoring, in/out cooler temp and thrust bear- ing temp. Additional advanced monitoring includes: dynamic load monitoring, vibration monitor- ing for gears and bearings and oil condition monitoring of particulate matter and water content. www.zf.com/marine (Image: ZF) www.marinelink.com 67
