Here is a picture gallery of the Komatsu D155 W underwater bulldozer at work sites. Dates and locations are not divulged.
The machine dates back to the ’70s. A total of 36 machines were produced. Production was discontinued 20 years ago. Maintenance was difficult. Seat water caused significant rust and corrosion.

KONIJN OF NETHERLANDS HAD A BETTER SOLUTION THAT DID NOT GET STUCK, AS IT MOVED LIKE A TURTLE BUT IT HAD A SMALLER SHOVEL AND LOWER PRIODUCTION CAPABILITY.
