Supply of spare parts, components, maintenance & repair services of Traction and SIBAS systems to DSB’s S-train

Description

DSB needs to extend the lifetime of DSB's S-train until 2040, when the new S-train fleet is expected to be fully operational. DSB is seeking a supplier to keep the current Traction & SIBAS systems on the S-trains fully functional for the operational lifetime extension of the fleet. DSB expects several critical components and spare parts to be obsolete within a timeframe of 18 months (calculated from June 2023), hence the Supplier must warrant availability of needed components and spare parts from January 2025. DSB expects contract to be signed leaving time for a mobilization phase of around 10 months. Siemens is the original equipment manufacturer (OEM) supplier of the Traction & SIBAS systems to the S-trains. DSB has limited or no documentation of the Traction & SIBAS systems and limited access and no rights to protocols and software in relation to the Traction & SIBAS systems. However, DSB will provide available access for inspection of both systems after prequalification Lot 1: To keep the Traction and the SIBAS systems fully functional for the operational lifetime extension of the S-train fleet, the Supplier shall deliver spare parts, components and upgrades of the Traction and the SIBAS systems and maintenance & repair services of components and of the two systems. As obsolescence of several critical components is expected to lead to supply shortage within a time frame of 18 months, the Supplier must expect reengineering and/or replacement supply of components within a very short time limit. In case of reengineering and/or replacement of components and/or spare parts, DSB requires, that the replaced components and/or spare parts can pass necessary homologation and/or safety approvals prior to installation. The Supplier will be obliged to deliver all information, documentation, technical supports, tests, certificates etc. necessary for the approvals etc. To avoid time consuming and expensive safety processes the spare parts and components must be OEM or equivalent. DSB also requires: 1) The Supplier present preventive maintenance actions for optimal failure rates and maintenance cost for spare parts and components in the systems. 2) The Supplier shall perform maintenance service on spare parts and repairable components in due time for DSB not to run low in stock on these. 3) The Supplier shall maintain and repair components to an extent where the need for reengineering actions are kept at a minimum. 4) The Supplier shall make it possible for DSB to carry out required maintenance and/or upgrade work onboard the trainsets within the DSB planned maintenance operations and workshop times. The S-train fleet was delivered from 1995 to 2006 and consists of SA,104 8-car trains and SE, 31 4-car trains. The oldest 8 8-car trains are slightly different to the rest. About the SIBAS system: The SIBAS system (SIemens BahnAutomatisierungSystem) is employed for modulating and logic control functions in rolling stock. The CCU (Central Control Unit) is the main controller in the SIBAS system. Each train is equipped with two redundant CCU’s acting in a master/slave principle. The SIBAS system interfaces to other onboard systems and components onboard the train set partly via an RS485 bus system, locally positioned input/outputs (handled by redundant so called KLIP stations) mounted throughout the train set cars, an RS232 interface to the GSM-R radio and two RS232 interfaces to the ToDat system (=Train Data sent to the landside). One of the RS232 connections is also used as service interface. In addition, the CCU has a redundant RS485 interface used when coupling to other trains. The VDU (Visual Display Unit) integrates with the SIBAS system and the CCU via the RS485 bus system. The VDU is the main driver interface displaying data sent from the CCU and sending user input data to the CCU. Each train is equipped with two VDU’s. About the Traction system: Each litra SA train is equipped with two traction converters and each litra SE train is equipped with one traction converter. The TCU (Traction Control Unit) is the main controller in the traction converter. The TCU interfaces to the SIBAS CCU and to the brake control system. The power input to the traction system is the catenary line voltage of 1650 VDC nominal an operating range within 1000-1900 VDC and an overvoltage limit of 2340 V. The maximum input current is 830 A. The traction converter has a three-phase output in the range 0-1300 VAC and 0-530 A. Traction converter features include jerk control, slip/slide control, electrical braking power returned to the catenary line and in case this cannot absorb the power then sending it to the brake resistor, and brake blending with the frictional brake system. The tender comprises the SIBAS and the Traction system. The SIBAS system includes the CCU’s, the KLIP stations and the VDU’s. Further specifications and information will follow and be issued only to those who have expressed an interest Interested suppliers must express their interest before the time limit in IV.2.2 by informing DSB in writing, cf. 1.3). The contract will be awarded without publication of a further call for competition. No ESPD is to be fulfilled at this stage nor tender documents will be issued at this stage; these documents will follow and be issued only to those who have expressed an interest.
