In shipbuilding, there was a problem in removing foreign material adhering to the inside of the line (piping) through which fuel was supplied to the engine.
Shipbuilder L conferred with us about eliminating foreign material adhering to the inside of piping through which fuel was supplied to the engine in the production line for large vessels. They wished to prevent this serious problem in the fuel supply facilities.
Because the installation position was in an area where no flame was permitted, they made the countersuggestion of an air knocker that employs air as an activator and that has variable impact force. We proposed the pipe-fixation type because they requested that the knocker be fixed to the fuel pipe.
They are fully satisfied with the result. There is no problem, and they placed an additional order.
Because they were fully satisfied with the product, they placed a repeat order.
