Subsea Pigging Skid
The subsea pigging skid consists of seawater filter, centrifugal pump, venturi tube, flowmeter, pressure gauge and data acquisition system. Water filling procedures include automatic filling and auxiliary filling through centrifugal pump. The air and debris in the pipeline are exhausted and removed by the pigging ball during operation. Water filling and pigging can be completed separately or together.

Subsea Cleaning Unit
The subsea cleaning unit consists of seawater filter, subsea piston pump, pressure sensor, and data acquisition system. It serves to destroy the adhesion between objects to be removed and subsea pipeline through flushing from high-pressure water jet and remove the objects through water flowability. The operation process is of high quality, high efficiency and cleaning.

Subsea Distribution Unit
The subsea distribution unit includes ship Downline subsea pressure test channel and subsea hydrostatic testing unit pressure test channel. This unit has one 2" and one 1" output channel, and the expandable channels have been reserved. Each channel is integrated with temperature sensor and pressure sensor, enabling the pressure of multiple subsea pipelines to be tested simultaneously.

Spilled-oil Recovery Unit
The spilled-oil recovery unit includes automatic subsea hole opener, power pack, and underwater heating system. By the umbilical cable to transfer subsea signals and hydraulic power, the adjustment and hole opening operation of the subsea hole opener are completed by the remote command from the water surface. The hot steam and heating coil are used to increase the fluidity of heavy oil and improve the oil pumping efficiency.

Underwater Hydraulic Shear
The hydraulic shear is a underwater rescue tool to provide shear force. Cooperating with ROV system, it's capable of cutting underwater structures of different diameters. The key components of the shear are made of high-strength materials such as alloy steel and titanium alloy to meet the anti-corrosion requirements of the marine environment, reducing its weight and improving the convenience of operations.
