The sulphur-free sustainable residual fuel consists of used cooking oil and contains no fossil fuels. This leads to a significant carbon reduction of 90%, thus contributing to a reduction of Boskalis’ carbon footprint.


This world first for Boskalis is the result of the ‘Boskalis on Bio’ pilot program launched in 2015 in collaboration with engine manufacturer Wärtsilä and GoodFuels. With this program Boskalis aspires to achieve an important reduction in carbon emissions from both its vessels and its dry earthmoving equipment and trucks.

Since Boskalis launched the program, it managed to successfully use several biofuel blends on both dredging and offshore installation ships and on dry earthmoving equipment as an alternative to fossil fuels.

The 143-meter long trailing suction hopper dredger Willem van Oranje, was taken into service in 2010, and has a hopper capacity of 12,000 cubic meters, with a total installed power of 13,870 kW. The dredging vessel can also dredge to a depth of up to 62 meters.
