We would like to make a cleaning unit to be used under water. It is to be partly in PVC and partly in steel - stainless steel
parts. Project is in initial phase. Design is rather simple - the PVC box - 1 x 1.2-5 meter - and then some circles in the bottom - if you turn unit around. To be used to clean underwater part of shiphulls. We suggest compensation to be - 1 part for the initial design 1 part when we make the prototype 1 part as an amount for each unit made. Market is not very big - may be 20-30 units - or a bit more. Project fee mentioned - Small project - is the first basis amount - then the additional amounts if prototype and if manage to get it into production.
