“Windship Technology Ltd, a sail power concept that is being developed by a consortium of five key players in the global shipping industry, could revolutionise the way tomorrow’s vessels carry goods across the world’s oceans.”

The Problem

70-80% of freight charges are being consumed by fuel costs leaving little for the ship owner or profit.

The Facts

  • Bulk carrier fleet is young – 40% delivered in last 5 years
  • Bulk commodity markets are slow because of the economic downturn
  • Ship yard capacity is huge – will prevent any upturn in the market
  • Present freights do not cover daily running costs and give no contribution to capital costs
  • Values of bulk carriers have dropped by 80% since 2008
  • The shipping markets and ship values will remain sluggish for many years
  • A new generation of ships are built with 15% lower bunker consumption
  • That will leave the 5 – 10 year old ships moribund as charterers will prefer the bunker saving ships

Windship Technology

Windship Technology Ltd, a sail power concept that is being developed by a consortium of five key players in the global shipping industry, could revolutionise the way tomorrow’s vessels carry goods across the world’s oceans.

The new concept, known as the Auxiliary Sail Propulsion System (ASPS), uses fixed wing sail technology, whereby two 35-metre high masts installed on the deck of a vessel will each have three aerodynamic wings fitted. The masts or rigs rotate automatically to exploit the power of the prevailing wind and, as the speeds and angles of the wind change, the system develops more power, allowing reductions in engine power to be made in order to achieve the same speed and so maximise on fuel saving.

The consortium approached Lloyd’s Register to give an independent assessment of the ASPS. LR’s Technical Investigation Department (TID) carried out CFD work on a Supramax bulk carrier in varying wind directions and speeds. These showed that ASPS has the potential to provide more than 50% of the required propulsive thrust a vessel needs depending on conditions. In the right conditions this could save a typical bulk carrier 30% of its fuel costs on a voyage.

The Ships

At the beginning of 2010 the worldwide fleet of seagoing cargo vessels of all types was over 102,000 vessels. Of that general dry cargo non containerised bulk carriers numbed some 36,585 ships with 456 million tons deadweight capacity. (Source: Review of Marine Transport 2010 – United Nations Conference on Trade and Development).

There were new ships delivered in 2011 and 2012 numbering some 1295 being 18.1 million tons, and an order book into 2014+ of another 188 million tonnes deadweight capacity. Most of the Owners of these ships suffer from the problems already outlined in the earlier sections.

“We are taking the very latest principles of sailing and applying them to modern ship design.”

Simon Rogers, Technical Director

The Solution

  • Windship Technology equipped ships, out of the redundant fleet, will reduce their annual fuel consumption by at least 30%
  • For Handy + Panamax that will be a saving of around MUSD 2.0 – 3.0 per year which brings vessels to profitability.
  • Such Windship fuel efficient ships will move to the top of the charterers priority lists.
  • Such ships will be the first to secure charters and avoid waiting time
  • Priority in ports will be secured saving weeks of waiting for berth.
  • Carbon emission trading will yield profits.
  • The value of such ships may increase reducing mortgage exposure.
  • Risky financial restructuring may be avoided by adopting the fuel saving Windship system.

The 30% saving on an average fuel consumption for a Handy/Panamax type will be at least US$2.5 to US$3 million per annum which will allow the ships to recent back to their estimated per-built/pre-purchased profitability, and repay investment, loans and mortgages. (This does not include increased benefits from Ballast Legs)

“Could this enable a step change in efficiency? Quite possibly?”

The Verification

Verification of this project has been conducted by Lloyds Register, Wolfson Unit, Southampton University Professor Wilson, Head of Ships Sciences.

Tankers, container ships and other freighters, most of which burn a coarse petroleum sludge called bunker fuel, now contribute about 3.3 percent of global carbon dioxide emissions, though some analysts argue the figure may be considerably higher. Without new restrictions, emissions from increased shipping could nearly triple by 2050.

(New York Times, July 22, 2011).

Environmental Considerations

  • EU and IMO are targeting a 50% reduction in shipping emissions before 2050
  • New legislation and carbon trading schemes will encourage reductions and punish the big emitters
  • Shipping compares with the 6th highest greenhouse gas emitting country in the world
  • Important charterers like Cargill and Unipec (China´s largest oil trader) will only charter the more fuel efficient ships listed in “Rightship” and ”Shippingefficiency.org” Others will follow their example.
