Aguiding tenet oftheESABALT concept isthat all
maritime users in the Baltic Sea can operate more
safely by collaboratively building and maintaining
situationalawareness.
3 INFORMATIONEXCHANGEPROCESS
Informationexchangeisakey enablerofsituational
awareness due
to the fact that no individual in a
system as complex as the maritime transportation
systemholds alloftheinformationrelevanttohisor
hersafety.Similarly,atthelevelofavessel,novessel
collectively holds all of the information relevant to
herownsafety.Therefore,inorderto
obtainasmuch
relevantinformation as possibleand maintaingood
situational awareness, a vessel and her crew must
engage in various information exchange processes.
This section outlines some of the guiding
assumptions concerning the information exchange
processes used in the maritime domain, which are
relevantfortheESABALTproject.
Assumption
1:Informationmustflowfromshore‐
to‐ship, ship‐to‐shore, and ship‐to‐ship. All three
typesofinformationflowareexpectedtobeusedby
the ESABALT system. Shore‐to‐ship and ship‐to‐
shore are extremely important because centralized
information management, for example, through a
VTSoperatorprovide
ahigherlevelofreliabilityand
qualityassuranceformaritimeinformationexchange.
However, VTS operators cannot maintain good
overall situational awareness without regular
updates from vessels, for example, updating of
routeswhenavesselchangesherplannedroutedue
to unforeseen circumstances. Lastly, ship‐to‐ship
communicationisassumedto
bebeneficialduetothe
fact that the ship‐to‐shore and shore‐to‐ship links
may not be available all of the time and in all
locations at sea. In addition, ship‐to‐ship
communication may provide the most timely and
reliable means of communication when the
information is of
critical nature and needs to be
exchanged quickly (e.g. maneuvers to avoid
collision). Another example of ship‐to‐ship
communication isdirect transmission and reception
ofpositionandheadingdatathroughavessels’AIS
transponder.
Assumption 2: Different vessels have different
communication capabilities. In particular, larger
vessels,suchascommercial
cargoorpassengerships
are assumed to have greater communication
capabilities compared to, e.g. pleasure boats. For
example, most commercial ships have VSAT
capabilities, which allow them to send and receive
dataglobally,whereasapleasureboatmayhaveonly
VHSorcellularradios/phones.VHS may be limited
to voice‐only
communication and cellular phone
coverageisgenerallyonlyavailableincoastalareas.
Asaresultofthisassumption,theESABALTsystem
mustbeinteroperablewithdifferentcommunication
systems, and it must adapt itself based on the
communicationcapabilitiesoftheuserterminal.
Assumption 3:Adequate standards for maritime
information exchange
already exist. Standardized
protocols and formats for exchange of maritime
information are important because the information
must be processes by multiple parties, and
furthermore the formats must be machine readable,
in order to facilitate automation. Examples of
relevant existing standards include NMEA 0183,
NMEA2000,S‐57,S‐100,S‐101,
andS‐102.
Assumption 4: Information exchange processes
shouldbehighlyautomated.Asaresultofasurvey
of potential users, it was apparent that information
exchange processes should be highly automated, in
order to not burden the crew with additional
workload.Inaddition,automatedsystemsgenerally
requirelesstraining,
soautomationalsoreducesthe
trainingburdencreatedbytheESABALTsystem.
Assumption 5: Most users are assumed to be
cooperativeandtrustworthy.Sinceitisplannedthat
the ESABALT system will utilize crowdsourcing to
build up situational awareness, it is important to
considerthetrustworthinessofthoseparticipatingin
the
collectionof information. If anuncooperativeor
malicious user intentionally provides falsified
information, thiscan have serious consequences for
theoverallsystem.Thesystemmusthavecapabilities

user behaves contrary to the guidelines and
principlesintheend‐userlicenseagreement,thenhe
or she will be banished from the system. Because
mostusersarelinkedto

and have a reputation to uphold, they will be
motivated to operate according to established
proceduresandguidelines.
4 ESABALTSTAKEHOLDERS
The maritime sector comprises a number of
processes; for example, transport process,
information exchange process, and disaster
management process, etc. The ESABALT system is
primarily targeted towards persons and entities
involved with the information exchange process.
