Advantages and Features
HSEM control board system by HELI consists of 11 boards including main control, power supply, communication, and drive. ARM+FPGA architecture, dual-redundant hot backup system, full coverage of faultdiagnosis system. It supports up to 42 channel of 4-20mA current collection, 48 channels of solenoid valve drive output, and 16 channels of diaital communication. The sub-module of 20kb/s carrier communication with the surface control station has obtained the SLL3 safety level calculation report issued by DNV and completed the self-test of API-17 standard
Subsea production system (SPS) is the core equipment of deep-sea oil and gas development. As oil and gas explorationexpands to deep seas (> 1500 m) and ultra-deep seas, traditional Control methods rely on surface platforms face highcosts and delayed response. To solve the above problems. The electronic Control module SEM has emerged as theintelligent brain" of underwa-ter production systems.
Currently, there are related products in China that have passed the API certification of DNy, such as CNOOc and HarbinEngineering. However, only foreign manufacturers, such as ABB and Aker-Solution, have SEM products that meet the SLL3safety level standards.
Heli Tech Energy Co., Ltd. takes it as its responsibility to break through foreign technological-blockades and achieve the localization of key components and systems in the petroleum in-dustry. Currently, theunderwater electronic module designed and manufactured by Our com-pany has obtained the SIL3safety levelcalculation report issued by DNV (the first in China) andcompleted the self-test of API-17 standard.

FAQ
Q: What safety certification standards does the HSEM control system comply with, and are the certification documents available for verification?
A: The HSEM control system meets the SIL3 safety level standard and complies with the requirements of API-17 standard. The official SIL3 calculation report issued by DNV and the API-17 compliance test report are available for review upon request.
Q: Can the HSEM control system be integrated with existing subsea production system (SPS) equipment, and what communication protocols does it support?
A: Yes, the HSEM control system is designed for seamless integration with mainstream subsea production system equipment. It supports common industrial protocols such as EtherCAT, MODBUS, and the communication protocols specified in API standards, ensuring compatibility with on-site control platforms.
Q: Does the HSEM control system support remote monitoring and maintenance, and what technical conditions are required for this function?
A: The HSEM control system is equipped with a built-in B/S architecture remote access module, which supports real-time data monitoring, fault diagnosis, and remote parameter adjustment. To enable this function, the on-site system only needs to meet basic network connectivity requirements, and the data transmission process complies with industry security encryption standards to ensure data security.
Q: Are spare parts for the HSEM control system available locally, and how long is the lead time for urgent spare parts supply?
A: We have established a complete spare parts supply system, with common spare parts stored in local warehouses for quick access. The lead time for regular spare parts delivery is within 7 working days, while for urgent spare parts requests, we can provide emergency delivery services within 48 hours in regions covered by our service network.
