Environmentally friendly equipment

We take targeted measures to invest in equipment that will enable our operations to be as environmentally friendly as possible. An environment in which project and contract specifications include not just price but also sustainability values is precisely the kind which challenges us to keep innovating. In our Dutch market we grasp the opportunities we are offered and we have had certification since 2012 for the highest rung on the CO2 performance ladder. In other regions we comply with international legislation and regulations in addition to our own policy. We act ahead of changes in the law and create the conditions for rapid implementation by investing in an extensive R&D program.

The International Maritime Organization (IMO) draws up rules aimed at further reducing emissions from shipping, while the European Union’s Marine Strategy Framework Directive also imposes a range of measures for the reduction of maritime emissions. At the same time, several large ports around the world have introduced the Environmental Ship Index. These ports reward cleaner ships by reducing port fees. We consult with the authorities on these matters through national and international sector associations such as the European Dredging Association (EuDA) and the Dutch Association of Hydraulic Engineers, as well as by contributing our technical knowledge in order to make emissions measurable. In doing so, we seek to work towards realistic regulations for our industry that enjoy broad support.

Energy management task force

Our special Energy Management Task Force keeps a close eye on the development of national and international legislation and regulations on emissions, and instigates emission-reduction initiatives through innovations in equipment and working methods. Headed by a member of the Board of Management, the Task Force is composed of specialists and professionals from across the organization. The Task Force pools knowledge and best practices and promotes awareness within the organization. At the sector level, the Task Force is working on developing an industry standard for the dredging fleet for measuring CO2 emissions per production unit.

Co2 performance ladder result in 2013

In 2013 Boskalis once again obtained certification for level 5, the highest level attainable on the CO2 Performance Ladder. This is a tool used by government organizations and businesses in the Netherlands to encourage companies that take part in often complex tenders to exercise carbon awareness in their business operations and in the execution of projects.

Key points of focus are energy saving, efficient use of materials and the use of sustainable energy.Boskalis wants to draw more explicit attention to the sustainable impact of the works it executes in the Netherlands and has therefore decided to also start measuring and publishing the CO2 impact of a number of eco-engineering projects. That is why it has been decided to determine the carbon footprint as well for a number of eco-engineering projects in the Building with Nature program, and to focus in particular on the positive impact of CO2 capture using natural solutions. We will be doing this for projects such as the Sand Motor. On our projects we want to show more clearly that fuel-saving measures have both environmental and economic value. We want to engage in dialogue with clients about this issue. More information about Boskalis activities relating to the CO2 performance ladder can be found on www.boskalis.com/nederland (Dutch only).

Measures aboard our fleet

Both individually and in conjunction with suppliers, sector organizations, knowledge institutes and NGOs:

  • we conduct research into the use of cleaner and more efficient propulsion systems and cleaner fuel (see also the case text 'Greater sustainability in the chain');

  • we look at implementing energy-saving measures on our equipment;

  • we encourage recycling initiatives for parts such as worn-out pump casings, impellers, cutter teeth and floating dredging pipes;

  • we pursue a sustainable dismantling policy (see also the case text 'Industry leader in responsible ship dismantling');

  • where possible we take steps to ensure the separate collection and disposal of waste;

  • we use water efficiently and responsibly;

  • we encourage environmental awareness and motivation in our own employees and those employed on behalf of Boskalis.

CO2 emissions in 2013

Boskalis measures and reports on the fleet’s total CO2 emissions on the basis of fuel consumption. The absence of a clear measuring standard precludes the meaningful statement of relative emissions per production unit, making the annual consumption reports difficult to compare, even without the effects of acquisitions and divestments. A complex set of factors comes into play here. Our dredging and offshore fleet consists of different types of vessels, and the deployment of older or, conversely, more modern vessels and the capacity utilization of the fleet also have a bearing on fuel consumption in a given year. In addition the nature of the projects can also result in a distorted picture; for example, a cutter suction dredger that has spent a year on projects involving a lot of hard soil will have much higher energy consumption than in another year when it has worked in softer soil.This means that higher or lower fuel consumption in a given year is not an adequate reflection of the quality of our environmental performance. We do not therefore believe it is useful to set a quantitative target for annual fuel consumption at this time.

In order to present balanced reporting on our fuel consumption and carbon emissions, Boskalis is working with others in the dredging sector to reach agreement about an industry standard for CO2 emissions per production unit.

In 2013, this resulted in a prototype for a new calculation model that can be used as a standard. In the Netherlands, Boskalis is negotiating through the Dutch Association of Hydraulic Engineers with the Ministry of Public Works for this calculation model to be applied to a program aimed at reducing carbon emissions on coastal replenishment projects.

Reporting at Dockwise is also complex because of differences in fleet composition, age of the vessels, utilization of the vessels, distance travelled and cargo transported. All of these aspects affect fleet energy consumption. Continuous improvements have been made to report, measure and reduce fuel consumption.In terms of both fleet and office organization associate companies are consolidated pro rata to the participating interest we hold.

The total group emissions in 2013 amounted to 1.63 million tons CO2 (2012: 1.05 million tons CO2). This increase of 55% is primarily attributable to the acquisition of Dockwise and its inclusion in the report. If Dockwise had been excluded, there would have been an increase of 4% in emissions.

Boskalis

The emissions for the Boskalis fleet include, in addition to the traditional dredging vessels, the activities of SMIT. The total emissions amounted to 940,000 tons (2012: 901,000 tons). This increase of 4.3% can be attributed on balance to the following elements:

  • the higher level of utilization of the hopper fleet (44 weeks compared to 41 weeks in 2012) resulted in an increase in emissions by the hopper fleet of 7.3%;

  • as a result of the sale of the Ursa and lower utilization of the cutter fleet (16 weeks compared to 25 weeks in 2012), cutter fleet emissions fell by 45.8%;

  • as a result of the high level of activities and the resulting high level of fleet utilization, emissions from SMIT activities rose by 23.7%.

Dockwise

The CO2 emissions from the Dockwise fleet amounted to 534,000 tons in 2013. This includes emissions for the entire calendar year but not the emissions for the Dockwise Yacht Transport activities, which were sold in 2013.

Smit Lamnalco

The CO2 emissions by Smit Lamnalco amounted to 156,000 tons. The increase of 3.8% is attributable in part to the takeover of the Harbour Towage activities in Gladstone, Australia and higher fleet utilization in 2013.
