Environmentally friendly equipment

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. We act ahead of changes in the law and create the conditions for rapid implementation by investing in an extensive R&D program.

Taskforce Energy Management

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 the Offshore Energy and Dredging divisions. 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. In 2014, the Task Force met once and various initiatives were taken again. An overview can be found below of the measures on our fleet that were discussed in the meetings of the Task Force in 2014 and in recent years. Some of them emerged from the Meet the Buyer sessions (see Our suppliers).

Measures on our fleet

Our new equipment complies with the strictest requirements for energy consumption. For reasons including operational economy, we are also making our existing equipment more sustainable where possible. Both individually and in conjunction with suppliers, sector organizations, research institutes and NGOs, we are continuing to invest in:

The application of cleaner and more economical propulsion units and cleaner fuel

Examples include:

  • The trial with biodiesel in Boskalis Nederland trucks was completed successfully in 2014. We have purchased 250,000 liters of this innovative fuel, widening the market for the supplier, SkyNRG. Using 250,000 liters of this cleaner fuel resulted in a saving of 148MT CO2, a cut of 10% in NOx emissions, and a reduction of 30% in SOx and particulate emissions.
  • Partnership with SeaNRG, a SkyNRG sister institute, which we launched in early 2015. SeaNRG is working on the development of a ‘drop-in’ biofuel for shipping that is expected to comply with stringent sustainability requirements. We have the intention to conduct a pilot project together.
  • The test with GTL on one of our tug boats in the port of Rotterdam was a success. Using this cleaner fuel has reduced NOx emissions by an average of 9.5% and it could therefore make a substantial contribution to the achievement of the NOx reduction targets for the port of Rotterdam.

The application of energy-saving measures

Examples include:

  • Performance tests began for the larger dredging vessels in 2014. We are looking at how well a trailing section hopper dredger is performing by comparison with the standard and investigating the causes of shortfalls in performance. On the basis of this analysis, we will be initiating improvements that will also enhance environmental performance at the same time. We want to introduce these performance tests for all vessels in our fleet.
  • A plan has been presented for the years to come for improving the energy efficiency of the vessels. The aim is to maximize the efficiency of installations (cooling ventilation and air conditioning) and lighting on board. We can claw back the associated investments through energy savings in a few years. Using sustainable LED lighting also leads to a reduction in material consumption, lower maintenance costs and less transportation of replacement materials.

A sustainable dismantling policy

In 2013, the Shipbreaking Platform recognized us as an industry leader for our sustainable ship dismantling program. In 2014, we worked further on our partnership with a yard in Mexico, Ensenada, contributing knowledge through intensive collaboration so that the yard can comply with our requirements (see the theme text in this report).

Cradle-to-cradle recycling and waste

We have established a procedure with Beelen Groep for recycling worn floating dredging lines. We have also established cradle-to­cradle chains with the foundries Van Voorden, Allard and Magotteaux for worn impellers, dredging pumps and with Vosta for pickpoints (see the theme text in this report). Since this initiative began, more than 2.7 million kilos of material have been delivered and re-used. We comply with the IMO MARPOL regulations, which prohibit waste being discharged overboard, barring specific exceptions. Our vessels larger than 400gt have a waste management plan in which all actions involving the disposal or incineration of waste are recorded in a ‘Garbage Record Book’. The ports we visit are required to accept this waste.

Proper use of water

We have a responsible approach to ballast water. Two pilot projects with innovative treatment systems were launched in 2014. We will be reporting on those projects in a subsequent CSR report.

Encouraging environmental awareness among our colleagues

In 2014, there was, in collaboration with the Pro Sea NGO, a Marine Environmental Awareness course again for our fleet colleagues. The course looked at marine ecology, sound waste management, ballast-water treatment, and emissions. The program has been tailored to the Dredging situation.

Result Co2 performance ladder 2014

As in the past five years, Boskalis Nederland obtained certification on the CO2 Performance Ladder in 2014; for the third time in succession, certification was at the highest level of the ladder (level 5). The certificate covers all parts of the business working for the Dutch market. The CO2 Performance Ladder is an instrument that is used in the Netherlands by government agencies and business to encourage companies to participate in often complex tender procedures to adopt CO2-aware procedures in their own operations, during projects and in the chain. The basic principle underlying the Ladder is that efforts made by companies to further energy savings, the efficient use of materials and sustainable energy will be recognized. The level achieved by companies on the CO2 Performance Ladder gives them an advantage in tender procedures: the higher the level on the Ladder, the greater the advantage for the company during the tender procedure.

Boskalis Nederland is implementing a fuel-consumption reduction policy for the company and on the projects. This has resulted in a range of actions in 2014: for example, a study was conducted of the fuel-efficiency of the equipment by analyzing fuel consumption in relation to productivity. There was also a campaign in which behavior change was central and in which drivers and super­intendents on projects were approached personally. These actions are followed up in 2015.

In addition, Boskalis Nederland was one of the parties behind the initiative for an innovative development project as part of the Ecoshape program ‘ecosystem-based CO2 footprinting’. That project involves us working together with a range of partners on the ambition of ensuring that, by 2020, hydraulic engineering projects can have a CO2 balance that, during the entire life cycle, is 20% better than the conventional approach. This will be achieved by taking the carbon emissions of the equipment, the relevant features of the borrow area and the ecosystem in question into account as early as the design phase.

More information about the activities of Boskalis Nederland in the field of sustainability and on the CO2 Performance Ladder can be found on (only in Dutch).

CO2 emmissions in 2014

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. 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.

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 the Netherlands, through the Association of Hydraulic Engineers (the Dutch trade organization), Boskalis is talking to Rijkswaterstaat (the Dutch Directorate General for Public Works and Water Management) about the application of a dedicated computer model for coastal replenishment projects. We have proposed adopting the fuel consumption of the very largest vessels (hoppers, cutters and backhoes) as the guiding principle and comparing those fuel consumption figures in tenders. The supplier who proves that their fuel consumption is lowest will be given the highest fictive discount. Rijkswaterstaat is considering this proposal.

Total group emissions

The total group emissions in 2014 amounted to 1.59 million tons CO2 (2013: 1.35 million tons CO2). This increase is attributable to the high utilization of the cutter suction dredgers at Dredging, and a sharp increase at Offshore Energy as a result of the acquisition in March 2014 of Fairmount activities and a busy year at Dockwise.

Dredging & Inland Infra

Total emissions at Dredging & Inland Infra amounted to 562 thousand tons (2013: 521 thousand tons) and approximately 94% of those emissions can be attributed to the traditional trailing suction hopper dredgers and cutter suction dredgers. This increase of 8% can be attributed on balance to the following elements:

  • Even though the utilization of the hopper fleet as a whole fell to 40 weeks (2013: 44 weeks), the size of the fleet increased in 2014. The trailing suction hopper dredger Fairway (35,500 m3) went back into service at the start of the second quarter and, in mid-June, a new trailing suction hopper dredger, the Strandway (4,500 m3), also went into service.
  • Due to a number of major cutter projects, the utilization of the cutter fleet increased sharply in 2014 to 36 weeks (2013: 16 weeks). As a result, total emissions from the cutter suction dredgers increased by almost 140% in 2014.

Offshore Energy

The CO2 emissions from the Offshore Energy fleet amounted to 936 thousand tons in 2014 (2013: 727 thousand tons). This increase is fully attributable to the following elements:

  • The Fairmount vessels acquired in March 2014 have been included for the first time in reporting since that date;
  • Utilization of the Dockwise fleet was very high in 2014 and the flagship, the Dockwise Vanguard, was at work throughout 2014 (2013: three quarters);
  • In 2014, a number of new vessels were commissioned, including the Ndeavor, Smit Sentosa and Smit Seraya.

Towage & Salvage

The CO2 emissions from Towage & Salvage amounted to 87 thousand tons (2013: 95 thousand tons). The fall of 9% is attributable to the ongoing roll-out of the Towage strategy, in which activities are housed with joint ventures as much as possible. In mid-2014, Boskalis established two joint ventures with SAAM S.A. from Chile under the shared name SAAM SMIT Towage for the joint continuation of the harbour towage activities in Brazil, Mexico, Panama and Canada. With effect from the third quarter, these activities were deconsolidated in accordance with IFRS 11 and they are no longer included in reporting.
