Project name:
Scheme Design Consultancy (SDC), Verification & Validation (V&V) for Kuching Urban Transport.
Project description:
The Kuching Urban Transportation System (KUTS) will serve as the backbone of Greater Kuching's public transportation network. Its primary mission is to combat and alleviate traffic congestion, ultimately enhancing productivity and acting as a catalyst for economic opportunities along its routes. In Phase 1 of the KUTS initiative, our focus was on the design, construction, and commissioning of two urban lines, specifically Automated Rapid Transit (ART) lines, spanning a total length of approximately 52.6km. To ensure seamless connectivity, the operation of KUTS Phase 1 will be complemented by a comprehensive feeder bus service, offering passengers vital first and last-mile transportation solutions.
Our role:
Throughout the entirety of this project, Nippon Koei Mobility provided two main services: Scheme Design Consultant and Verification and Validation.
The Verification and Validation aspect of this project involved a comprehensive review and approval process. We reviewed and offered feedback on the Verification and Validation plan for System Package 1 and System Package 2, addressing their responses and closing out review comments for approval. Our team provided clarification related to the General Specification (GS), Particular Specification (PS), and Interface Specification (IS) during the detailed design phase. We also reviewed and approved submissions to ensure that System Package 1 and System Package 2 met their Reliability, Availability, Maintainability (RAM), and Safety targets. This included reviewing and approving test and commissioning documents, witnessing and signing off on various reports, and supporting our client during the Defects Liability Period (DLP)/Maintenance Period or as needed.

This LRT network encompasses a total length of 6km, featuring six strategically located stations and a dedicated depot.
Our role:
The scope of this project was to provide a comprehensive review of the system's design to ensure its alignment with the Employer's Requirements (ER). This involved a thorough examination of design elements and their compliance. Additionally, we assessed the utilisation of relevant codes of practice and standards as stipulated by the ER to maintain design quality and safety. We also conducted an exhaustive review of all drawings and technical documents pertaining to system works, ensuring accuracy and completeness. To facilitate effective communication and collaboration, we committed to attending all technical design meetings coordinated between the system works contractor, the main contractor, and our client, promoting a well-coordinated and successful project execution.
Project name:
Supplementary design and execution of the interlocking and ETCS 2 in the railway section Kelenföld (excl.) – Százhalombatta (excl.), Hungary
Project description:
The railway section extending from Kelenföld to Százhalombatta had to undergo a significant upgrade with the implementation of the advanced European Train Control System Level 2 (ETCS L2). This cutting-edge technology promised to enhance the safety and efficiency of train operations on this double line, contributing to the modernisation and improvement of the entire rail network in the region.
Our role:
In this project, we were responsible for a wide range of critical tasks and consultations. We provided consultancy for the design of specialised interfaces tailored to Simis IS electronic interlocking components, notably Level Crossings (Simis LC), coded track circuits, and various Block systems. Additionally, we were responsible for designing specific interfaces between Simis IS interlocking and the ETCS L2 system, ensuring seamless integration between these crucial railway technologies. Our team conducted a comprehensive impact analysis of the new Simis IS system, offering insights into its broader implications.

Project name:
Independent Safety Assessment of Replacement Work of Electric Point Machine For Heavy Loads In Region Daop 1 Jakarta, Daop 3 Cirebon And Daop 5 Purwokerto In Indonesia
Project description:
The Indonesian Railways (PT KAI) acquired Siemens BSG9 point machines initially configured for single-point operation. However, a modification became necessary on-site to enable the internal point circuits to operate coupled points sequentially. It was crucial that the point control circuit within the interlocking system remained unchanged, and no alterations to the interlocking itself were permitted.
Our role:
As an Independent Safety Assessor (ISA), our team carried out a site visit to assess the old point-related interlocking circuits compared to the modified ones. Tests were performed at Kebumen station to observe interlocking behaviour during specific point failure conditions. Additionally, verification of documents for content, proper review processes, and traceability were undertaken by our team of dedicated professionals. The Technical Safety Report (TSR) was examined and assessed, with identification of possible hazardous situations and recommendations for mitigation measures. Additional tests were proposed to check for hidden, undetected short circuits that could compromise safety. We also provided assessment reports for 3 representative coupled point circuits at Kebumen, Klari, and Cikampek stations. These reports were prepared and submitted to the client, detailing specific technical specifications and detection parameters for each station:
- Kebumen:110V AC, Single phase point machine BSG Type R842, Detection 50 V DC
- Klari: 220V AC, Single phase point machine BSG Type R844, Detection 12 V DC
- Cikampek: 380V AC, Three phase point machine BSG Type R840, Detection 30 V DC
