Description

Using high quality and durable components, CMR satisfies all marine and offshore requirements for harsh and demanding environments, minimizing maintenance costs down time.

Certified by Siemens:
As an authorized system integrator for the use of Siemens S7 series PLC’s, we have developed a range of world-class systems using this technology including:
• power management
• generator control
• vessel monitoring
• jacking monitoring
• skid control
• CMR supplies these switch gear and power management systems to international vessel owners rig owners abd FPSO operators.

Frame & enclosure:
• All-around perforation rows with a 25mn hole grid for individual installation
• Flexible door system for all requirements
• Door opening angle up to 180 degree
• Spring-loaded locks reliably prevent doors from opening unintentionally

Surface treatment:
• Optionally power-coated, wet painted or sendzimir galvanized

Material:
• Frame and enclosure are manufactured from sheet steel in the following thicknesses
• Frame: 2,5 mm
• Enclosure: 2,0 mm
• Degrees of Protection to IEC 60529
• IP30, IP40, naturally ventilated, IP54 unventilated

Variable busbar system:
• Differing requirements for the busbar system call for individual options, SIVACON offer modules for economical setup and high level safety
• Busbar position at top
• Busbar system for rated currents up to 7400 A
• User-oriented graduation or rated currents
• Rated peak withstand current lpk up to 375A
• Separation of busbar compartment from the device compartment
• Transport unit joints easily accessible from above

Withdrawal Unit Design:
• Cubicles for motor and cable feeders in withdrawable-unit design offer highest operating comfort, optimum safety and availability. By virtue of the guiding with drawable principle easy and rapid changes or adaptations are possible. Thus, individual modules can be supplemented or exchanged. Even compartments may be converted during operation. The with drawable-unit design of SIVACON offers the highest possibility availability.
• High degree of safety by virtue of type-tested standard modules
• Outgoing feeders up to 250 kW
• Non-fused and fused protection
• Test and disconnected position degree IP 30
• Standard operator interface for all with drawable units
• Isolating gaps on the supply and feeder sides
• Space-saving sizes of with drawable-units from 100 mm minimum module height
• Cable connection compartment at front or rear
• Easy adaptation to changing operating conditions without shutdown of switchboard


Sivacon withdrawable-units:
• Standardized design in eight module heights (100, 150, 200, 300, 400, 500, 700 mm)
• Clearly visible withdrawable-unit positions (connected, test, and disconnected position)
• Integrated maloperation protection in all withdrawable-units
• Control plugs up to 40-pole an additional bus contacts (optional)
• Hinged front panel of withdrawable-units for adjustments (more or equal module of 200 mm)
• Insertion support for easy moving of the withdrawable-units (>250 A)
• Plenty of space for auxiliary equipment by possibility of fitting components at the rear
• Lockable disconnected position for safe working at the consumer
