Testimonials

As the technical supervisor of the shipyard, we value the technical adaptability of accessories the most. The domestic shafting solution provided by Haipeng not only perfectly matches the design requirements, but also reduces the ship's sailing resistance by 12% through fluid dynamics optimization. More importantly, their team of engineers is on-site for debugging throughout the process, and this professionalism makes us completely relieved.

Technology Trust Type
Last year, a sudden order was placed during the typhoon season, and Haipeng completed the emergency delivery within 72 hours, helping us avoid terminal demurrage. From the intelligent quotation system to the special car delivery, the whole process is transparent and efficient. This That is the real 'customer first'!

Efficiency Sensitive Type
After comparing with many suppliers, Haipeng's domestic alternative solution has reduced our unit purchase cost by 25%. What's more surprising is that their full-cycle energy consumption optimization service has reduced the annual maintenance cost by another 18%. This wave of cooperation has made a profit!

Cost-Oriented
We have cooperated with Haipeng for 5 years. They are like our 'technical brain'. Every time a new ship model is developed, they will actively provide shaft adaptation suggestions, and the global service network also makes after-sales worry-free. This kind of partnership cooperation is what the industry should look like!
