New module from Royston identifies optimum vessel speed

Diesel power specialist Royston has enhanced its Eco Speed analysis capability as part of its enginei electronic fuel management system (EFMS) to enable ship operators to identify and maintain optimum vessel speeds for efficient fuel usage across different operational modes.

{mprestriction ids="1,2"}Devised with marine engineering specialists from Newcastle University, the Eco Speed feature enables shipping operators to manage vessel and fleet performance in the most efficient way possible without impacting on day to activities.

The new module uses real data from the vessel, rather than sea trial or test bed data, to build an accurate profile of fuel consumption during different operational modes.

Eco Speed can be set up remotely by Royston technicians to establish the operational profiles for different vessel modes. A simple step by step initialisation process then enables ship staff to build up a true picture of actual vessel operation in the selected modes.

This information is conveyed prominently to the standard main enginei onboard display to provide a real time guide for the crew on how the optimum speed can be maintained for maximum fuel efficiency.

The Eco Speed initialisation process can be re-run at any time to ensure that the vessel profile is adjusted to reflect any change in conditions or status that might affect performance.

For instance, engine overhauls or hull cleaning can have a significant effect on the economical speed of a vessel and re-setting the Eco Speed feature after such works will provide an immediate update of optimum speed characteristics.

In addition, changes in external operational factors such as adverse weather, sea conditions or tidal changes can also have an impact on best operational speeds and can also be taken into account by re-running the initialisation process.

Eco Speed calculates the unique optimum performance profile for individual vessels and provides clear guidance on the required speed changes that need to be made during a voyage to maintain operation within the most fuel-efficient range.

Royston’s enginei EFMS system uses Coriolis flowmeters and sensors to accurately monitor the fuel being consumed by each of a vessel’s engines, which is tracked against GPS data, voyage details and operational mode. The data is collected, processed and relayed to bridge and engine room-mounted touchscreen monitors to enable the ship’s master to adjust vessel speed and take whatever other actions are needed to maximise efficiency.

  • 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.
