Onshore Power Supply System (OPS) – Port of Aarhus

PoA is planning the construction of shore power facilities on the grounds of the container terminal in Aarhus.  The scope of services includes the planning, procurement, construction and trial operation of a new shore power system to be built for the simultaneous supply of several container ships with electrical energy during port berthing times. The certification of the individual components, as well as the overall systems, each with the ship in accordance with the standard, is also part of the service.    The project is divided into two lots:   • Lot 1: OPS   • Lot 2: CMS     The subject of this call for tenders is only Lot 1: OPS.    In accordance with the IEC 80005-1 standard, a certified shore power system must be installed. A containerized solution for the system is favored. The complete technology required for a functional system, including a flood-proof foundation, must be installed. Furthermore, the cable feed to the transfer boxes (including connection to the transfer system from lot 2) is part of the contract. PoA will provide cable pulling systems for this purpose, which are to be used during execution.    The plant is to be expanded at a later date. Only the first phase of the plant is currently being put out to tender.     A system with a total capacity of 3 x 3.75 MVA in accordance with IEC 80005-1 is planned to supply the following scenarios:   (a) Supply of 1 mail liner and 1 feeder  (b) Supply of 2 feeders  In the current project it is planned to install 2 CMS systems for the supply of container vessels. As such, the max capacity is 7.5 MVA per vessel (main liner) at each location.   The required voltage and frequency are as follows: 50 Hz & 60 Hz as well as 6.6 kV in all possible combinations.  All necessary central components (transformers, frequency converters, output switchgear, control and monitoring system) must be installed in the new OPS station. The cables are to be supplied and the cable routing between the shore connection system and the quay system (junction boxes, transfer equipment), as well as to the connection point of the input switchgear, is to be implemented. The commissioning of the entire system, including junction boxes and transfer technology, must be planned and implemented. The preparation of the design planning on the basis of this invitation to tender is part of the contractor's service. The contractor is also responsible for preparing the implementation planning.    The existing 10 kV MV switchgear - outgoing feeder panel is defined as the interface to the power supply. The overall interfaces to the ships are the plugs of the transfer equipment (CMS). Part of this tender is the cable pull onto the connection to the CMS. The connection between the cables and the CMS will be located at the quay/service road. The OPS Lot must provide and install suitable cable length for cable pull (between OPS and the CMS interface). The connection torewards the CMS will be done by the CMS lot.   The supplier of Lot 1 has overall responsibility for system integration, which is part of overall commissioning and overall certification.  Interfaces to PoA/operator are the LV supplies, possible connection to a terminal fire alarm system or direct interface to public fire brigade; connections to the IT/communication infrastructure and to the billing/energy management system for electrical energy for the ships.    Technology and cables are to be planned and installed in the existing system or in coordination with the PoA. Any necessary civil engineering work is to be carried out by the PoA. Existing roads can be used for parts of the route.     Construction will take place within the ISPS area of the terminal during ongoing port operations. Port operations have priority. Accordingly, on site work must be coordinated and kept to a minimum. In particular, work in the quay area may be restricted by port operations.     The planning is to be prepared on the basis of a functional service description and is to be provided in the following three stages:  1. design planning  2. implementation planning  3. work and assembly planning.
