Construction of a butane gas storage with Nippon Foundation Engineering as drilling sub-contractor and a propane gas storage with New Japan Development as drilling sub-contractor. 60 meter long vertical and horizontal holes are drilled which will then be pressurized to prevent gas from escaping. Hole straightness is a key factor which is why Wassara was chosen by both companies.

Result:

An often asked question is if you can run the Wassara hammer on sea water. This project is ample proof that this is indeed possible.
