Dutch dredging major 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' trailing suction hopper dredger 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 allows 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 'Boskalis on Bio' pilot programme launched in 2015 in cooperation with engine manufacturer Wartsila and GoodFuels. With this programme Boskalis aims to realise a substantial reduction in carbon emissions from both its vessels and its dry earth moving equipment and trucks. Since the launch of the programme, Boskalis has successfully used various biofuel blends on both dredging and offshore installation vessels and on dry earthmoving equipment as an alternative to fossil fuels on domestic projects such as the creation of the Marker Wadden nature area and the installation of export cable to the Borssele offshore windfarm.

The 143m LOA Willem van Oranje, which entered service in 2010, has a hopper capacity of 12,000m3 and a total installed power of 13,780kW.

Further from home, Boskalis has been awarded a contract by the Ministry of National Planning and Infrastructure, Republic of Maldives, for the development of the port of Gulhifalhu, located some 4km from the national capital, Male. The contract, valued at some €45 million, forms part of the Ministry's strategic plan to improve and develop the port infrastructure, providing a climate adaptive solution making this part of the Maldives resilient to rising sea levels. Boskalis will reclaim an area with an initial volume of six million m3 of sand using a mega-trailing suction hopper dredger. The scope of works, due to start in the fourth quarter of this year and finish in the second quarter of 2020, also includes rock revetment work for the shoreline.

Boskalis has already executed a number of climate change adaptive dredging and reclamation projects in the Maldives since the turn of the century.
