Dredger Purchase Inspection

When considering the purchase of a used cutter suction dredger, you want certainty about the technical condition of the dredger. You can get this certainty by having us perform a purchase inspection. Our purchase inspections map out the entire technical condition of the cutter suction dredger. We approve the dredger on about 300 points. We have listed the main points that we go through during an inspection here.

- Internal combustion engines

- Cooling water and lubricating oil system

- Oil hydraulic system

- Spuds

- Gauge indicators

- Dredge pump

- Ladder constrution

- Cutterhead

- General layout pontoons

- Winches and Anchors

- Cabine and instruments

Immediately after the inspection, the findings will be discussed with you as the client and any other interested parties. A clear expertise report is then drawn up. This report contains the detailed list of points, a list of material defects (clarified with photos) and a list of advice. The expertise report is drawn up in English by default. Unless otherwise agreed, we will send you the expertise report digitally the day after the inspection. A few days later the paper signed version will arrive at your office.

Practice has proven that in many cases a purchase inspection pays for itself. In 9 out of 10 cases, we find substantial defects. In a possible purchase contract, you can make agreements with the selling party in advance about how the findings from the inspection will be handled. Normally the essential defects are resolved by the selling party (or the expected repair costs are deducted from the agreed purchase price).
