PetroChina has achieved a significant milestone in enhancing its offshore engineering service capabilities.
On July 2nd, a new 4,000-ton power supply vessel (PSV) with electric propulsion, built for PetroChina's offshore engineering unit, was successfully launched in Dalian, boasting a designed cargo capacity double that of the largest vessel currently in service.
This vessel represents PetroChina's first offshore support ship to be equipped with a pre-installed interface for an energy storage battery system, enabling a future "oil-electric hybrid" configuration, marking a critical breakthrough in the company's efforts to build up its offshore service and support infrastructure.
The vessel achieves key technological advancements in three main areas: hybrid power, hazardous chemical supply, and noise reduction.
In terms of power, the hull is pre-fitted with an interface for a high-capacity battery.
Once upgraded, it will be capable of flexibly switching between three power modes: generator, battery, and the "oil-electric hybrid" system.
This allows for stable power supply with minimal fluctuation during precision operations like dynamic positioning, while also offering significant advantages in energy savings, emission reduction, and a greener operational profile.
For cargo, the vessel has a deadweight tonnage of 4,300 tons and a deck area of 920 square meters.
Furthermore, through optimized fire and explosion-proof design, it has gained the capability for the safe transport of low-flashpoint liquids and hazardous chemicals like methanol and ethylene glycol.
This upgrade transforms it from a standard transport ship into a versatile "offshore supply station," providing robust support for material logistics in complex offshore operational scenarios.
Regarding habitability, the vessel benefits from full-ship acoustic modeling and systematic "quiet" modifications.
Noise levels in the living quarters have been reduced by 8 to 20 decibels, and hull vibration attenuation has reached 94.9%, significantly improving comfort for crew during long-distance operations and creating a healthier, more livable environment for personnel on extended offshore assignments.
Currently, the overall construction progress of the vessel has reached 80%.
Upon entering service, it will effectively address functional gaps in the existing fleet of PetroChina's offshore engineering unit, substantially strengthening the company's self-sufficient operational support capabilities at sea.
It will provide solid equipment support for PetroChina Company Limited's deepwater and distant-sea oil and gas development projects, as well as its new energy service initiatives.
