Royal Boskalis Westminster and biofuels supplier GoodFuels are set to take the next key step in the Boskalis on Bio programme for the testing of sustainable biofuel oil. Following earlier successful tests with drop-in blends of light biofuel and marine gasoil, Boskalis’s Willem van Oranje will be the first dredging vessel in the world to operate on 100% biofuel oil.
The sulphur-free sustainable residual fuel consists wholly of used cooking oil and contains no fossil fuels. This enables a substantial carbon reduction of 90%, thereby contributing to a reduction of Boskalis’ carbon footprint.
This world-first for Boskalis is the result of the pilot programme launched in 2015 in co-operation with GoodFuels and engine manufacturer Wärtsilä. With this programme, Boskalis aims to realise a substantial reduction in carbon emissions from its vessels and its dry earthmoving equipment and trucks.
Since the launch of the programme, Boskalis has successfully used various biofuel blends on dredging and offshore installation vessels as well as on dry earthmoving equipment as an alternative to fossil fuels. For example, they were used on the projects to create the Marker Wadden nature area and to install the export cable to the Borssele offshore wind farm, both in the Netherlands. The 143 m-long trailing suction hopper dredger Willem van Oranje, which was taken into service in 2010, has a hopper capacity of 12,000 m3 and total installed power of 13,870 kW. The versatile dredging vessel can dredge to a depth of up to 62 m and is deployed on the most diverse maritime infrastructure projects around the world.
