Keeping pace with industry trends to drive the electrification of the shipping sector.
As China’s shipbuilding and offshore engineering equipment industry accelerates its quality improvement and upgrading, ship electrification has become the core engine driving the green shipping transition. Dalian Haien Gebhard Electrical Apparatus Co., Ltd. keeps pace with industry development trends, continuously deepening its expertise in the field of marine electrical control equipment, and providing core supporting products for the green and intelligent transformation of ships.
I. Industry Background: Ship Electrification Ushers in a Historic Opportunity
On June 11, 2026, China successfully completed its first ship‑grid interaction test, with an all‑electric tugboat smoothly feeding power back into the grid. This milestone marks a critical step in extending the energy internet from land‑based vehicle‑grid integration to marine applications, injecting strong momentum into the electrification of the shipping sector.
Meanwhile, the China Classification Society’s “Rules for the Construction of Domestic‑Voyage Sea Ships” (2026), as amended, will officially come into effect on July 1, imposing stricter requirements on shipboard electrical systems and creating structural growth opportunities for the marine electrical control equipment industry.
II. Core Products: Comprehensive Coverage of Marine Electrical Systems
Dalian Haien Gebhard Electrical Apparatus Co., Ltd. specializes in the research, development, and manufacturing of marine electrical control equipment. Its product line covers the core components of marine electrical systems, providing high-quality integrated solutions for various types of vessels:
| Product Name | Functions and Applications |
|---|---|
| Main Distribution Board | The core hub of a ship’s electrical power system, responsible for the distribution and protection of electrical power throughout the vessel, ensuring continuous, safe, and economical operation. It is suitable for various types of commercial vessels, including bulk carriers, tankers, container ships, as well as offshore support vessels. |
| Console | The interface between the control and electrical systems, featuring buttons and indicator lights on the central control console, is an integrated control system that combines power distribution, motor drive, and automated monitoring. |
| Monitoring and Alarm System | Real-time monitoring of the operational status of shipboard electrical equipment achieves a fault‑prevention accuracy of 99%, providing round‑the‑clock assurance for safe vessel operations. It complies with the classification society’s “Smart Engine Room” additional notation requirements. |
| Shore power box | A critical interface device for connecting vessels to the onshore power grid during port calls, delivering triple-zero benefits: zero emissions, zero pollution, and zero noise. It is compatible with both high‑voltage and low‑voltage shore power systems and supports adaptive dual‑frequency operation at 50 Hz and 60 Hz. |
| Electrical control cabinet | The core control unit for marine electrical systems employs programmable controllers and industrial fieldbus technology, replacing conventional relay‑based logic control to meet the power‑propulsion control requirements of new‑energy vessels. |
| Foghorn | An essential acoustic signaling device for ensuring navigational safety, it emits warning signals in adverse weather conditions to safeguard vessel operations. It complies with the relevant regulations of the International Maritime Organization (IMO). |
| Electronic inclinometer | Real-time monitoring of a vessel’s attitude angles, providing data to support stability assessments, is one of the core sensors in an intelligent ship situational awareness system. |
III. Technical Advantages: Keeping Pace with Standards and Pursuing Continuous Innovation
In the face of the technological trend toward increasingly advanced ship electrification, Dalian Haien Gebhard Electrical Apparatus Co., Ltd. has been continuously upgrading its product technologies:
- The main distribution board is equipped with an intelligent power management system (PMS) that optimizes the coordinated operation of batteries, generators, and loads in real time, increasing energy utilization by 15%–25%.
- The monitoring and alarm system features predictive maintenance capabilities, providing intelligent early warnings of equipment failures while simultaneously generating maintenance and repair decisions.
- The shore power unit supports seamless grid connection between ship and shore, enables “one‑button switching” of voltage and frequency, and ensures uninterrupted power supply throughout the entire process.
- The electrical control cabinet adopts a modular design, making it compatible with new-energy vessels such as hybrid‑powered, all‑electric, and fuel‑cell‑powered ships.
- All products comply with the certification requirements of classification societies such as CCS, ABS, LR, and DNV, and meet the latest standards stipulated in the “Rules for the Construction of Domestic‑Voyage Sea Ships” (2026).
IV. Looking Ahead: Supporting the Zero-Carbon Transition of Green Shipping
In the first quarter of 2026, China’s newly awarded offshore engineering orders increased by 36.4% year on year, firmly maintaining its position as the global market leader in this sector. High-end specialized vessels and offshore engineering equipment have become the main drivers of order growth. Dalian Haien Gebhard Electrical Apparatus Co., Ltd. will continue to deepen its expertise in the field of marine electrical control equipment, providing robust support for the green and intelligent transformation of ships through core products such as main switchboards, control consoles, monitoring and alarm systems, shore power boxes, electrical control cabinets, fog horns, and electronic inclinometers.
We firmly believe that, as the Smart Shipping 2030 Action Plan advances, more intelligent vessels will sail into smart ports. Dalian Haien Gebhard Electrical Apparatus Co., Ltd. is committed to working hand in hand with industry peers to propel marine electrification from inland‑river demonstrations into coastal widespread adoption and breakthroughs in deep‑sea operations, thereby contributing to China’s strategy of becoming a strong maritime nation.
