Stena extends energy saving programme with NAPA

NAPA has announced that it will install its vessel efficiency software on a further four Stena Line vessels as part of the shipping company’s Energy Saving Programme (ESP).

The software monitors fuel consumption, speed, departure status and loading data, and can transmit back to shore in real time for analysis. It will be installed on the ferries Stena Britannica and Stena Hollandica, and on the freight vessels Stena Transit and Stena Transporter.

Stena’s ESP has been running since 2005, with the first NAPA implementation taking place in 2007. The new vessels will bring the total number of ships with the software to 26.

Stena conducts eco-efficiency monitoring and analysis from the shore, and the company say the programme has resulted in verified fuel savings of $9 million.

“At NAPA we understand that ship operators are under increasing public, regulatory and financial pressure to control their fuel costs and boost environmental credentials,” said NAPA’s Johan Nyström, VP sales, EMEA & Americas.

“We also know that the first step to really effective fuel saving programmes is a clear baseline against which to measure any future savings achieved by efficiency initiatives.”

“Determining a testing process to verify results on a small scale before rolling the programme out has enabled Stena Line to invest only in proven solutions that work on its specific vessels and routes.”

Those routes include passenger ferries operating around Scandinavia, the United Kingdom and the Baltics, providing connections between 10 countries. Getting accurate data on fuel efficiency is key to reducing consumption, according to Lars-Erik Hellring, ESP project manager, Stena Line Scandinavia.

“Stena Line's Energy Saving Programme has enacted more than 200 energy reduction initiatives since 2005,” he said.

“As time goes on and we aim to extend existing gains even further, the initiatives designed to reduce fuel volume become increasingly challenging to measure accurately. Without clear and accurate evidence of success, which is what NAPA’s software delivers, it would be difficult to design an effective fuel consumption reduction programme, especially in an industry when savings as small at 0.5 per cent can mean a significant cost saving.”

“NAPA’s real time monitoring and reporting system enables crews onboard and shore-based personnel to work more closely together to achieve efficiency. Each team is equipped with tablets to allow officers to follow fuel consumption figures in real time, displaying the current fuel consumption per nautical mile – something really easy to understand and therefore easy to act upon.”

  • Fuel choice the essential decision in shipping's decarbonisation, finds DNV GL

    DNV GL – Maritime has released the fourth edition of its Maritime Forecast to 2050. The purpose of Maritime Forecast to 2050 is to enhance the ability of shipping stakeholders, especially shipowners, to navigate the technological, regulatory and market uncertainties in the industry, and set shipping on a pathway to decarbonisation. It is based on a library of 30 scenarios which project future fleet composition, energy use, fuel mix, and CO2 emissions to 2050. Sixteen different fuel types and 10 fuel technology systems are modelled in the report.

    “The grand challenge of our time is finding a pathway towards decarbonisation,” said Knut Ørbeck-Nilssen, CEO of DNV GL – Maritime. “Reducing GHG emissions is rapidly becoming the defining decision-making factor for the future of the shipping industry. The pressure to act decisively is mounting. Perfect is the enemy of good, and so we mustn’t wait for an ideal solution to arrive and risk making no progress at all. Using a wide range of scenarios involving different fuel types and technologies, and varying degrees of regulatory pressure, our new report helps to map a way forward, offering shipowners clear insights on how to meet the challenges and opportunities ahead.”

    The Maritime Forecast identifies the choice of fuel as the essential factor in decarbonising shipping. The industry is at the beginning of a transition phase, with many potential options emerging alongside conventional fuels. This increasingly diverse fuel environment means that engine and fuel choice now represent potential risks that could lead to a stranded asset. Factoring in the impacts of availability, prices and policy, on different fuels, makes the choice even more complex.

    To capture this complexity and help make this picture clearer the Maritime Forecast offers a wide range of scenarios, outlining the potential risks of a particular fuel choice. To make the ramifications concrete, alongside the pathways, the Maritime Forecast includes detailed analysis of a Panamax bulk carrier newbuilding. By stress testing technology decisions under the various pathways and scenarios, the Forecast presents potential performance and the carbon robustness of the various design choices.

    The 30 scenarios result in widely different outcomes for the fuel mix in the fleet. In the scenarios with no decarbonization ambitions, very low sulphur fuel oil, marine gas oil and LNG dominate. While under the decarbonization pathways, in 2050 a variety of carbon-neutral fuels holds between 60 per cent and 100 per cent market share.

    Under the decarbonisation scenarios it is hard to identify clear winners among the many different fuel options. Fossil LNG gains a significant share until regulations tighten in 2030 or 2040. Bio-MGO, e-MGO, bio-LNG and e-LNG emerge as drop-in fuels for existing ships. By 2050, E-ammonia, blue ammonia and bio-methanol frequently end up with a strong share of the market and are the most promising carbon-neutral fuels in the long run.

    A surprising result from the model is the relative limited uptake of hydrogen as a ship fuel, as a result of both the estimated price of the fuel and the investment costs for the engine and fuel systems. Hydrogen, however, plays an integral role as a building block in the production of several carbon-neutral fuels such as e-ammonia, blue ammonia and e-methanol, all of which gain significant uptake under the decarbonization pathways. It may also find niche applications in some vessel types, such as ferries and cruise vessels, as well as in specific regions where investments have been made into local production and distribution.

    The Maritime Forecast to 2050 is part of a suite of Energy Transition Outlook (ETO) reports produced by DNV GL. The ETO has designed, expanded and refined a model of the world’s energy system encompassing demand and supply of energy globally, and the use and exchange of energy between and within ten world regions.
