Virtual Arrival
Virtual Arrival An OCIMF /INTERTANKO project reducing
emissionVirtual Arrival is all about managing time and managing speed.
It’s not about blanket speed reduction to match current market conditions.
Virtual arrival is about identifying delays at discharging ports, then managing the vessel’s arrival time at that port through well managed passage speed, resulting in reduced emissions but not reducing capacity.
Virtual Arrival,A way to reduce emission
Background• Potential emission reduction for existing shipping said to be
up to 15% (at no cost?)• Fuel represents 60-80% of operation/running costs for owners • What drives/restricts emission reduction?• It is recognised that commercial and practical restrictions
sometimes apply• Virtual Arrival is a project that involves several stakeholders• Virtual Arrival implies co-operation and removing
commercial restrictions
Virtual Arrival:A way to reduce emission
by taking advantage of known inefficiencies in the supply chain andreducing speed when the terminal is not ready to discharge the cargo In addition to directly reduced emissions, other benefits are:• Reduced congestion and emissions in the port area • Improved safety• Reduced use of fuels• Potentially increased use of weather routing Important pre-conditions:• The safety of the vessel remains paramount• The authority of the vessel’s Master remains
unchanged• The basic terms of trade remain the same
Virtual ArrivalWhat is needed to do to make Virtual
Arrival work?
1. A known delay at the discharge port2. A mutual agreement between two (or more) parties to adapt the
ship’s arrival time to take advantage of the delay3. An agreed Charter Party clause that establishes the terms for
reducing the speed to adapt to the new arrival time4. An agreement on how to calculate and report the Virtual Arrival and
the performance of the vessel5. This may involve a Weather Analysis Provider (WAP)6. OCIMF/INTERTANKO and class are producing transparent
standards for verification of WAPs
But mainly it’s a win–win situation for all,based on trust and transparency

Virtual Arrival An actual voyage undertaken.
• The oil traders had a stem loading from Batumi in the Black Sea. – Built up with a number of barges
and rail cars • The cargo destination was identified
as the Isle of Grain and there was a known delay at this port. – Tank space only available before
the 16th
Virtual Arrival – The Reality
Virtual Arrival The daily report
• An initial report of the voyage using historic speed and consumption data.
• The vessel is given a revised Estimated Time of Arrival (ETA) reduce speed to achieve this ETA.
• Daily progress reports issued to all concerned parties.
• A final report would be produced showing the savings during the voyage.
Virtual Arrival – The Reality • We approached the market and an owner that understood
and is receptive to the virtual arrival concept. The vessel was chartered.
• Vessel sailed on 2nd September 2009 and we engaged a Weather Analysis Provider to do the virtual arrival analysis.
• Vessel arrived in Isle of Grain at 1000 hrs on the 16th September and the virtual arrival was Sep 15th 0650.
• Emissions saved • CO2 183.2 mts• Nox 4.39 mts• Sox 3.49 mts
• This represents a 27% reduction in fuel consumptions and emissions over the length of the voyage and a bunker savings 58.83 mts of HFO
Meeting the challenge SummaryMaritime transport is by definition of an international nature. To preserve and enhance environmental performance, the public image of the world’s fleet and, where applicable, to retain being the means of preferred transport, we, as an industry, will be required to act in a responsible way, and there will be opportunities for innovation to meet this challenge.
In summary:• Virtual arrival has the opportunity to remove
inefficiency within the transport chain through an agreed and managed reduction of a vessel’s passage speed.
• It has the opportunity of delivering absolute reductions in emissions from the vessels involved.
