Power Management System PMS Platinum is an intelligent power management system based on the Geapas which is a stand-alone automatic power supply system including complete generator protection and management functions plus the advanced control functions eebeg by Platinum software to match different operation modes specifically developed to fit the outstanding requirements of an heavy lift jacking vessel.
All alarms and control functions commonplace in marine applications are supported by highly standardized proven and tested modules, including power management, anti-heeling, valve control, pump control, advanced monitoring with deviation alarms, exhaust gas temperatures and much, much more. All azimuth drives have independent command structures with separate speed and steering function combined in one lever. The V network is redundantly supplied from the V switchboards via two kVA distribution transformers.
For data communication to superior monitoring and control systems a RS interface Modbus is provided. For example, if high wind forces are sensed, the DP System will adjust the propulsor commands 22952 instead of waiting for the vessel to show a position movement due to the gust.
The transformers for propulsion and distribution are totally enclosed with side mounted double tube freshwater coolers AFWF and two 22952 fans for providing the necessary air flow. Over 60 common marine equipment manufacturer protocols are immediately available in the standard system, with more added through continuous development. Based on intensive studies including capability plots, advanced station-keeping simulations, power consumption plots under consideration of diverse environmental and operational conditions, an optimum propulsion configuration was developed with all involved parties.
The touch operator panel PC provides the following functions: A third secondary winding system is provided for an independent supply of debe auxiliary motor control center see page 5. Automation The total system is built up in a decentralized architecture with supervisory computers and autonomous Field Processing Devices connected to a redundant Ethernet dsbeg bus network structure.
These transformers are designed in IP44 and are air natural cooled. Prior switching on the main breaker the auxiliary star coil of the transformer is energized via the V auxiliary MCC to induce at the primary side a voltage with a deeg phase angle. By synchronising the different levers via an electric shaft system a common febeg to the port or starboard azimuth drives is possible.
The section breakers will be opened only in case of a bus bar failure e. Deeg consortium acting towards the shipyard and owner side as single source vendor providing the equipment from bridge to propeller incl. Jack-up operations are critically dependent on the prevailing sea state.

For operation, setting of parameters and control of the GPM a separate panel with touch screen display BAT is installed in the front door of the LV-compartment. S-Band Scanner 30 kW, 14 ft.
For subsystems like speed and azimuth lever control VDC are locally converted into 24 VDC to minimize the voltage drop at long cable distances. Special bus couplers separate the bus system between the switchboards to allow an operation also a switchboard section is out of operation. The MCS Platinum has been designed for totally hardwired channels and over software channels data from serial interfaces of third-party systems for supervision purposes distributed to 10 Field Processing Devices FPD decentralized in different locations on the vessel process area.
For smooth and automated operations several tie breakers and heavy consumers are controlled additionally, ensuring a safe operation even under jacking and DP conditions.
In the end the database contained more than Integration of 3rd party products is easily achieved via standard interfaces. MCS Platinum is offering as integrated standard functions: A Cisco based data distribution network Ethernet including active and passive components is installed on board. A common navigation and automation platform software allows the installation of any application to any Platinum series workstation i.

Each azimuth thruster is provided with a thrust bearing, shaft line bearings and brake. X-Band Scanner 12,5 kw, 5 ft. The propulsion drive system is laid out according to the latest DP2 requirements of the classification society Germanischer Lloyd GL. The overall design guarantees that a single failure in the system e. Additionally resistors are provided to reduce the inrush current from approximately 10 times of the nominal current to values in the range of nominal current.
This required analyzing the vessel with different physical configurations and loads as well as different power plant configurations. Each Z-drive is speed controlled rpm by an asynchronous motor. If the actual measurements are different than the operator commanded inputs, then the vessel control computing algorithm will adjust the output of the propulsion commands. To enhance the security of people, vessel and environment, routine sea state measurements is required. A star point earthing cabinet SPEC per kVA alternator is provided to detect and to limit an earth fault in the high voltage propulsion system.
Mimic diagram of power plant PMS Platinum The system is designed to handle six MV main diesel generators, one V harbour generator and one emergency generator. The transformers are of dry type i. In order to limit the inrush current, a pre-magnetizing circuit is installed for each propulsion transformer.
A redundant panel network is ensuring the alarm distribution to dedicated responsible persons.

The DP System uses feed-forward data to counteract environmental forces before they move the vessel off station.
Furthermore, the data of position receivers, navigation echosounders, gyro compass and magnetic compass as well as wind and weather measurement station is incorporated. SAM Electr onics – RAD wave field parameters such as significant wave height, peak wave period and peak wave direction, as well as surface current speed and current direction offering the continuous availability of wave data in rough seas, under harsh weather conditions with limited visibility and at night.
All drives are designed with fixed pitch propellers and are speed controlled by low voltage PWM-Converter drives – supplied via associated propulsion transformer from the V bus bar. Around sales and service locations worldwide ensure customer proximity.
Voyage Data Recorder 2 pcs. The MCC supplies all auxiliary equipments of the related drive e. Founded inthe company has been developing and manufacturing azimuth propulsion and manoeuvring systems, complete propulsion systems with power ratings of up to 30 MW, and steering systems for vessels of all sizes and types, for about 60 years. Additionally actual data e. To limit the total harmonic distortion factor THD all propulsion transformers are designed for a pulse characteristic to the mains.
