W
allenius operates some 180 ro-ro vessels together with its subsidiaries and partners,
including the world’s largest car carriers, which carry up to 8,000 vehicles. Lögdström says the company’s aim is that the fleet should be a world leader with regards to quality, safety and environmental standards. Even though shipping is the most energy efficient way of transporting goods, he says, the industry faces a huge challenge to decrease its environmental impact. “In Wal- lenius we are doing our best to reduce our environmental footprint.” For the Swedish firm this means more than merely complying with laws and regulations. “We want to be ahead and push legislation forward.” One way of doing this is to work with “upstream solutions” - trying to control the sources of waste in the first place, rather than treating them afterwards. Wallenius has already been working according to this philosophy since the 1990s, he stresses.
Ahead of the legislators In practice, this means Wallenius wants its vessels to use fuel that is as clean as possible. Only environmentally-friendly oils and lubricants are used. The company reduces nitrogen emissions by lowering combustion chamber temperatures, uses tin-free bottom paint and it always looks to optimise ship operations. Wallenius uses the world’s first IMO-approved chemical free system for ballast-water cleaning, PureBallast, which it developed together with Alfa Laval. From 2008, all new vessels are being delivered with Pure- Ballast systems. In addition, the company has started retrofitting its existing fleet and this process will be completed by 2015. “This will ensure that we are well ahead of the legislation,” comments Lögdström. Wallenius makes sure that the “green mes- sage” gets through in a number of ways. The company’s environmental commitment has lead to a relatively-large Environment and R&D group that currently consists of six people who work with colleagues at sea and ashore.
Since 1998, the group has had an Environ- ment Management System approved and cer- tified according to ISO 14001. All co-workers
also go through an environmental education in order to get a deeper understanding of the environmental aspects. Lögdström says that because Wallenius is known as a com- pany that takes environmental work serious- ly, it has noticed that it attracts people that are also engaged and have knowledge of this field. “That strengthens our position as a forerunner even more.”
Ambitious environmental targets Environmental engagement is a central element in the way the company does busi- ness. “We think this strategy has served us well so far and we believe it will strengthen our position even more in the future with the many environmental challenges that lie before us. Our strategy is to be leading the world through highly skilled co-workers with continuous competence development. We strive for a systematic, focused and cost efficient upgrading of the current fleet. Last but absolutely not least, when we develop new tonnage, we do it with ambitious targets on efficiency, quality, safety and low environ- mental impact.”
Together with its operating company Walle- nius Wilhelmsen Logistics (WWL), the com- pany’s goal is to reduce CO2
emissions by
30% on average across the entire fleet over five years (2008-2012). Of the 30%, 10% will come from technical measures, 10% from operations, such as “eco driving”, route planning, cargo handling etc, and the remainder from speed reduction, contracts and by making cargo deliveries in due time.
To obtain savings by technical measures Wallenius is taking a number of measures: - Optimised hull and propulsion (trying to design newbuildings for service instead of contract condition, improve aero-dynamic design – reduce height of bridge/applica- tion of bow wind screen, application of hull appendages/duck tail, low resistance rudders)
- Optimised machinery system efficiency (waste heat recovery, reduce losses from accommodation and ventilation, minimising SFOC by choice of main engine)
- Improved guidance for vessel operation (vessel characteristics guideline package

SPA-JIP: Reducing fuel costs and emissions on Wallenius Undine
Jesper Lögdström is playing an active role in the Service Performance Analysis Joint Industry Project (SPA-JIP) by providing the m/v UNDINE as a demonstration vessel. The SPA-JIP aims to reduce fuel consumption and emissions by analysing performance on board. Crews can use the results of the analysis to improve performance by chang- ing the trim condition or speed settings. The service performance analysis method developed in the SPA-JIP, corrects deviations in environmental and loading conditions to ensure that the performance comparison is carried out under equal circumstances.
The m/v UNDINE is being used to collect data to test the analysis method and to demonstrate the on board analysis tool to the participants. On board, the analysis tool is coupled to the NAPA database. Data analy- sis has already produced some interesting results regarding trim opti misation and the effect of drift on the vessel’s performance.
m/v UNDINE is also being used in many other energy-saving and emission-reducing projects at Wallenius. Lögdström comments: “Wallenius and other fore runners show what is possible and hopefully others follow.”
