Virtual Arrival
Virtual Arrival
An OCIMF /INTERTANKO project reducing emission
Virtual 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 and
reducing 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 Arrival
What is needed to do to make Virtual Arrival work?
1. A known delay at the discharge port
2. A mutual agreement between two (or more) parties to adapt the
ship’s arrival time to take advantage of the delay
3. An agreed Charter Party clause that establishes the terms for
reducing the speed to adapt to the new arrival time
4. An agreement on how to calculate and report the Virtual Arrival and
the performance of the vessel
5. 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
•

• 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 Summary
Maritime 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.
