General surface support buoys are entensively used in single point mooring (SPMsystem. The three main type are as below:
- Cylindrical Buoys.
- Chain thought Buoys.
- Pick-up Buoys.
                Gusets, flanges carbon steel to BS EN10025 Fe 430 A or B
                Central tube to BS 6323 Pt 3 HFS 5
Finish: Swivel assembly hot dip galvanized to BS 729 Zn2/Zn4 at 610 g/m2
Steelwok to be coal tar epoxy painted
Skin Colour: Orange, Yellow and others

Subsea Buoyancy
Evergreen can make buoyancy material used for subsea up to 7000m. Product of different opplications buoyancys are manufactured upon our advance subsea buoyancy material. We can make subsurface mooring buoys , cable float, pipeline buoys, ROV buoyancy module , special buoys, and other synmatic foam products.
Our high-performance subsea buoyancy material and synmatic foam have the following performance.
Â
| Item | Unit | Value | |||
| 500m | 1000m | 1500m | 4500m | ||
| Density | g/cm³ | ≤0.4 | ≤0.45 | ≤0.5 | ≤0.6 |
| Compressive Strength | MPa | ≥5 | ≥10 | ≥15 | ≥40 |

Photovoltaic Piling Rig also named Solar piling drill rigs is widely used in photovoltaic, foundation drilling, it is most advanced hydraulic drilling rig for solar drilling application. The rig can be operated in very flexible way.
The feed can be turned left and right in different angle to fit the variable application. The full coverage area for drilling is seriously considered to achieve extremely drilling position. For solar power station, Photovoltaic drilling, pile drilling and highway guardrail drilling as well as construction drilling is most suitable.
Besides piling drilling, it can do blasting hole drilling for mining.
It is fully hydraulic control solar piling machine, it can has highest drilling efficiency for operator, especially for time limited project. And the key components are from top end brand, such as Deutz AG diesel engine,Cummins engine, Yuchai diesel engine,Permco pump,Eton motor, Parker hoses and Rexroth pump. All these key components can make sure solar pile driving Machin has longest lifetime and least break down.
The Photovoltaic rig`s drilling model can be selected from impact hammer to rotary head for different geological structure.
Photovoltaic pile driver is not only for photovoltaic or soloar piling drilling, it also can work for water drilling and foundation drilling etc. multi-functional drilling work.
Solar pile driver has some unique design to has it to operate in every sharp slope area and in order to make operator a very vertical borehole in any position.
Yikyui PV pile driver has rotary boom with rotary platform. With this function, operator can drill in very accurate position with less moving of Pile drilling machine, which can save time and higher quality borehole.
