The port of Eemshaven is situated in the north of the Netherlands at the river Ems close to Germany, bordering the Wadden Sea. Most of the port area is reclaimed land outside the primary dikes. The area has been raised with 4 to 5 m sand, therefore providing stable soil conditions for on-shore developments.



soil-conditions-eemshaven-2016Based on cone penetration tests a W-E profile has been constructed directly North of the western part of the Juliana harbour basin. The depth of the soil profile is 50 m starting at approximately NAP+4,5 m. The profile shows a sandy top layer to approximately NAP -15 m, followed by a layer of clayey silt, silty clay to NAP-19 m/ NAP-23 m. Underneath follows generally a well compacted sand layer.

Soil profile W-E North side western part of the Julianahaven basin (length profile appr. 600 m.). The soil profile shown in gure 1 gives an impression of the soil conditions of this part of the Eemshaven. Variations can occur depending on the exact area of interest.


Jack-up vessels frequently visited Eemshaven during the last years. Due to the recent offshore wind farm projects these vessels frequently visit Eemshaven to load heavy equipment required for the construction of these wind farms.

The depth of the Juliana harbour basin varies between NAP-14 m and NAP-17 m. For jack-up vessels visiting the Juliana harbour leg penetration analysis have been carried out based on cone penetration tests. These results indicate that for loads between 150 Mega Newton and 250 Mega Newton penetrations between 4 m to 7 m below the seabed are to be expected. The legs penetrate the silty clay layer but penetration in the underlying sands is limited.

The maximum safe proximity of the legs of a jack-up vessel to the quay depend on the penetration depth of the legs. In order not to endanger the stability of the quay walls, leg penetration is not allowed in the passive zone of the quay walls.

Depending on the exact loads, quay and soil conditions distances from 15 m are to be expected. Please note that calculations of leg penetration and safe distance of legs to the quay wall are mandatory before acquiring permission from the harbour board.


Jack-up vessels can moor in the Beatrixhaven just in front of the quay, which enables them to use their own cranes for loading activities.
