When Furetank’s new ship, Fure Viten, leaves the shipyard, she is the best in class in the world when it comes to the United Nations climate targets for shipping. Thanks to gas propulsion and a unique combination of fuel saving solutions, it achieves a very low EEDI value of 4.65. This means that the new Furetank series of ships is already meeting emissions targets for 2050 today.
Today, Fure Viten leaves the Yangzhou shipyard: a 17,999 dwt tanker with a loading capacity of 20,300 cubic meters. This is an important step for the Swedish company Furetank Rederi AB, but also an international flagship in terms of environment and climate.
The United Nations International Maritime Organization (IMO) regulates emissions from new ships through the EEDI Energy Efficiency Design Index, where a lower value means fewer emissions. Today, the requirement for a ship the size of Fure Viten must reach less than 9.37 points, but Fure Viten has reached a value as low as 4.65 points: the best result in the size segment at this day.
We will be operating the ships that we are building now for the next 20 years, so we have put a lot of effort into researching what is the best possible technology that we can invest in today. Climate change is a reality and we think politicians mean what they say. So, if we are to survive as a shipping company in the future, we must do our best to reduce our impact on the climate and the environment, says Lars Höglund, CEO of Furetank.
All energy-optimized systems
The Fure Viten is the last ship in a series of eight to date, of which Furetank owns four and operates commercially. The series is designed by Furetank and FKAB Marine Design in collaboration with Wärtsilä, with the aim of minimizing fuel consumption. Throughout the design and construction process, the energy efficiency has been increased and the EEDI value has been improved.
We have been developing ships since the 80s and have used all our experience to optimize every detail. There isn’t a single system that we haven’t improved. This combination of interactive and energy-efficient technical solutions is unique, says Lars Höglund.
For example, batteries help reduce the use of auxiliary motors, a ducted propeller increases thrust and reduces power requirements, an improved hull shape minimizes drag, and the main motor and shaft generator use high frequency. variable to increase propeller efficiency and reduce fuel consumption.
Gas propulsion brings great advantages
The eight bi-fuel vessels will be operated with LBG (liquefied biogas) or LNG (liquefied natural gas). Gas propulsion offers major climatic, environmental and health advantages over oil. In combination with the technical optimizations, climate-affecting carbon dioxide emissions were reduced by 55% compared to older ships and eutrophic nitrogen oxides (NOx) by 86%. Emissions of acidifying sulfur oxide (SOx) and hazardous particles (PM) are virtually completely eliminated.
The next step will be to operate the ships completely without fossil fuels. We are in the process of securing the supply of larger quantities of biogas within about a year, thanks to an exclusive agreement with a supplier. My point is that in 2030 we will be operating these ships largely on LBG with zero fossil emissions, says Lars Höglund.
First in Europe with full shore power
The Fure Viten and predecessor sister ship Fure Vinga are the very first tankers in Europe fully equipped to operate energy-intensive cargo pumps with high voltage 6.6 kV shore power. This will further reduce emissions as soon as ports offer the opportunity.
The solution is being developed in collaboration with the ports of Gothenburg and Rotterdam, which are currently developing the full capacity electrical connection required to operate the pumps. A significant effort, because port emissions can represent up to 20% of the total emissions of an oil tanker, in an environment that is often even more sensitive to pollution and noise than at sea.
Achieved the UN target for 2050
With the delivery of the Fure Viten, the average carbon dioxide emissions of the intermediate Furetank fleet have been reduced by 50% compared to 2008. Already today, the series of vessels is fulfilling its share of the target of ‘IMO’s total emissions for the world fleet: halve emissions until the year 2050.
