The Subsea Excavation Specialists
TwinProp Specification Sheet
The KDM Marine TwinProp subsea excavation
system is the next generation, state of the art
development of the widely proven Mass Flow
Excavation technique. Counter-rotating propellers
are used to produce two high volume columns of
water which can be adjusted to any angle to best
suit the application. The design and multiple configurations of the KDM TwinProp make it the most
versatile MFE tool in the world.
Applications
The TwinProp is deployed using a crane or A-Frame
and is powered via high pressure hoses. Clump
weights or tugger wires are used to orientate and
stabilize the tool whilst it is operational.
