CABLE BURYING - DITCHING MACHINE
DESCRIPTION
This machine is used to lay pipes under sea. Vessel puts cable burying-ditching machine into the sea and controls it to work. The biggest advantage of this machine is can finish burying and ditching progress at the same time, which save lots of time and cost.
STRUCTURE
The burying and ditching machine is made up by 6 parts: 2 skids, middle supporter, 2 high pressure pumps, plow body, umbilical winch, hydraulic/electric control system and testing system.
Skids on both sides contact with seabed, float bowls can be installed on it to reduce pressure between the skids and seabed. Angle between skids and seabed is controlled by hydraulic cylinder, and locked by lock cylinder after the skids in demanded place. There are two doors under plow body to load and unload cable quickly. All the burying and ditching progress is controlled automatically. Umbilical winch provide electric power and control cable to the burying-ditching machine.
TECHNICAL PARAMATER

CONTROL SYSTEM
Burying-Ditching machine and umbilical winch both use one hydraulic system. Umbilical winch is driven by hydraulic motor and synchronous move with burying-ditching machine. Tension control-protect device con protect the umbilical cable out of stress. Burying-Ditching machine is also equipped a host winch to connect the pipeline between hydraulic unit to host machine.
