Activities related to the fleet
Our new equipment complies with the most stringent requirements for energy consumption. Partly for commercial reasons, we make our equipment more sustainable where possible by means of:
Use of cleaner fuels, such as biofuels. We launched a two-year biofuel pilot program in 2015. See pages 58-59 of this report.
Energy-saving measures by making the installations we use on board our ships, such as cooling, ventilation, air-conditioning and lighting, as efficient as possible.
Separate collection and processing of waste. We comply with the IMO MARPOL regulations, which prohibit waste being discharged overboard, barring specific exceptions. All our vessels over 400 Gt have a waste management plan.
Recycling of worn-out floating dredging lines, impellers, dredging pumps and pick points, resulting in the recycling of 704,000 kilograms of material in 2015. More information can be found in the case studies on our corporate website.
Mitigation of turbidity by using green valves on our trailing suction hopper dredgers. Boskalis has also developed a sensitive monitoring system that enables it to analyze turbidity caused by a dredging project at any given time, adapt the performance of the work accordingly and thus limit or prevent the ecological impact.
Responsible treatment of ballast water.
Preventative measures against oil spills.
Raising environmental awareness among our crew. In 2015, we once again organized two Marine Environmental Awareness courses for our fleet personnel in collaboration with the NGO Prosea marine education Foundation. The course covers topics including marine ecology, responsible waste management, treatment of ballast water and emissions. Our aim is for all our captains and chief engineers to have taken the course by the end of 2016.
Measures to limit the noise made by our equipment both above and under water and to reduce light pollution in vulnerable nature areas. We offer noise-reduction solutions for the installation of wind turbines and turbine foundations.
The Ship Energy Efficiency Management Plan (SEEMP) on board our ships serves to promote awareness of efficient energy consumption among our crew.
Sustainable ship dismantling policy
Boskalis is committed to dismantling the ships it decommissions in a safe and sustainable manner and is ahead of existing international legislation and regulations in this area. Prerequisites include additional stricter safety requirements, a hard surface on which to dismantle the vessel and the responsible disposal of the waste. For each ship the possibilities for responsible dismantling locally are assessed and weighed against the (enviromental) costs of transporting it over a long distance, for example to Europe for dismantling at a certified shipbreaking yard there. Where relevant, agreements are made with local yards in close consultation with the NGO Shipbreaking Platform to adapt business processes in such a way that they meet Boskalis’ more stringent requirements. During the shipbreaking process knowledge is shared with the local yards to enable them to attract more demanding clients following the operation. A good example of this approach involved the dismantling of three cutter suction dredgers at a yard in Mexico, as described in the case study on our corporate website.
We have been recognized repeatedly by the NGO Shipbreaking Platform as an industry leader in this field.
