Each switchboard could be further separated into 3 subsections interconnected by two section breakers which are normally closed.
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. Around sales and service locations worldwide ensure customer proximity. Over 60 common marine equipment manufacturer protocols are immediately available in the standard system, with more added through continuous development.
Special operation modes have been developed to fit the specific requirements of HLJVs. The DP System uses feed-forward data to counteract environmental forces before they move the vessel off station.

X-Band Scanner 12,5 kw, 5 ft. Special bus couplers separate the bus system between the switchboards to allow an operation also a switchboard section is out of operation. This consortium acting towards the shipyard and owner side as single source vendor providing the equipment from bridge to propeller incl.
For the Crew welfare an advanced IP-TV entertainment system for terrestrial and satellite television distribution including set top boxes in all cabins and some public areas is installed. A Cisco based data distribution network Ethernet including active and passive components is installed on board. To enhance the security of people, vessel and environment, routine sea state measurements is required. These transformers are designed in IP44 and are air natural cooled. General overview based on single line n diagram see below n Detailed view on propulsion, generators, control, alarms, status position of breakers, measuring values, etc.
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 offered by Platinum software to match different operation modes specifically developed to fit the outstanding requirements of an heavy 29552 jacking vessel.
Jack-up operations are critically dependent on the prevailing sea state. Based on intensive studies including capability 29522, 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. For economic sailing the Trackpilot function enables debg ship to sail along a track defined by way points.
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. 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.
The transformers are of dry type i. 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. Furthermore seven Uninterruptible Power Supplies UPSone per thruster drive, are provided to supply the associated V-switchboard sections and drive control system.
Each azimuth thruster is provided with a thrust bearing, shaft line bearings and brake.

Founded inthe company has been developing and manufacturing debsg 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 drbeg 60 years. 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 debef, exhaust gas temperatures and much, much more.
A star point earthing cabinet SPEC per kVA alternator is provided to detect and debeh limit an earth fault in the high voltage propulsion system. The overall design guarantees that a single failure in the system e. To limit the total harmonic distortion factor THD all propulsion transformers are designed for a pulse characteristic to the mains. For subsystems like speed and azimuth lever control VDC are locally converted into 24 VDC to minimize the voltage drop at long cable distances.
Automation The total system is built up in a vebeg architecture with supervisory computers and autonomous Field Processing Devices connected to a redundant Ethernet data bus network structure. Furthermore, the data of position receivers, navigation echosounders, gyro compass sebeg magnetic compass as well as wind and weather measurement station is incorporated.
Integration of 3rd party products is easily achieved via standard interfaces. Additionally actual data e. In the end the database contained more than 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.

Debwg 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 correct phase angle. Voyage Data Recorder 2 pcs. The touch operator panel PC provides the following functions: For smooth and automated operations several tie breakers and heavy consumers are controlled additionally, ensuring a safe operation even under jacking and DP conditions.
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.
In order to limit the inrush current, a pre-magnetizing circuit is installed for each propulsion transformer.
