New container ship design to save $3m in fuel

Ten ultra large container ships under construction at Hyundai Heavy Industries for APL are to feature a new design that aims to make them 20 per cent more fuel efficient per TEU compared with existing models.

The new design is the result of a collaboration project involving APL, Hyundai Heavy Industries (HHI) and DNV, to create ships optimised for an operating profile along the Far East to Europe trade route involving nine speed and draught combinations.

The companies say that the installed propulsive power could be reduced by about 16 per cent compared to the initial hullform optimised for one draft and speed condition, and could result in fuel savings worth about US$3 million per ship, per year.

The first of the new 13,800 TEU vessels is already under construction at HHI and will be delivered next year.

“In the current challenging market environment it is extremely important for APL to introduce efficient and flexible container ships, which help us to reduce slot costs,” said Cedric Foo, group deputy president and CFO of APL’s mother company, Singapore-based Neptune Orient Lines (NOL).

“These ships will be the most fuel-efficient ships ever built to the Asia-Europe container trade.”

“APL has decided to advance the delivery of the newbuildings, which have been ordered in 2011, using their superior fuel efficiency to make a contribution to cutting emissions as soon as possible.”

Container ships often operate in ‘off-design’ conditions which increase hull resistance and reduce propeller and engine efficiency. In the case of these new vessels, the ships will operate at speeds typically ranging from 15 to 19.5 knots but with a maximum speed of about 23 knots.

Using a sophisticated software system and virtual sea trials, the three partners say that they were able to analyse the proposed trading pattern of the ships and optimise accordingly.

“This is a new way of cooperation between the partners in a newbuilding project,” explains Ha Gyung Jin, executive vice president of the Basic Design Office in the Shipbuilding Division of HHI.

“Due to a concentrated and professional effort from all three parties within their respective roles we managed not only to keep the tight design schedule, but also to unlock an amazing potential for fuel savings.”

  • 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.
