The firm says ongoing analysis of submerged trial results indicate that the tools can perform to design specifications with the machine components all functioning as designed in submerged conditions.
The company stated this in its update of the submerged SPT trials at Motukea, outside of Port Moresby.
Nautilus states that submerged trials of the collecting machine and auxiliary cutter were completed late last year and the bulk cutter trials are anticipated to be completed in February.
The cutting performance of the auxiliary cutter has been particularly positive.
