2 IMPORTANCEOFMEASURINGTERMINAL
EFFICIENCY
According to Thomas and Monie (2000), ports and
terminals must measure their performance, because

3 IMPORTANCEOFCHEMICALTERMINALS
Chemical tankers, chemical ports and pipe lines are
the main components of the world chemical
transportation. Large quantities of liquid chemicals
are transported by tanker ships (Arslan, 2009) and
chemicalcargoeshavedifferentproperties,and
many
ofthemrepresentahealthandsafetyhazard,whichis
acriticalissue forthetankerindustry(Karimiet al.,
2002).Alsopipelinesplayanotherimportantrolefor
the transfer of the raw materials and products
betweenrefineriesandterminals,especiallylocatedin
the same geographical area or where maritime
transportation is not cost/effective like BakuTiflis
Ceyhan pipeline. And finally truck and railway
transportation modes are mostly used domestically
for shipping the products from the terminals to the
manufacturers.
As it is clear from the description, liquid raw
materialsandproductsaswellasliquidchemicalsare
commonly transported
by maritime transportation
mode because of its lowest cost per ton mile and
amount efficiency.All of these facilities require a
terminalwithitsberthorjettiesfortheshipsandalso
forthebarges,railwayforthetrains,locomotivesfor
the wagons, roads and stations for the trucks,
pipelines between
the terminals and/or refineries,
tank farms for the storage of the raw materials and
products, hoses or pipelines between the berth/jetty,
wagonandtruckloading/unloadingstations.
In today’s global economic conditions, there are
alsoworldwidestorageneedforchemicalmineraloil
andpetrochemicalindustryproducersandcustomers.
Chemical cargo ports
are facilities which meet that
needs. In the world, one of the most important
examplesofchemicalterminalsisPortofRotterdam.
Portof Rotterdamoffers more than 30 million cubic
meteroftank storagecapacityforalltypes ofliquid
bulk.Productshandledincludecrudeoil,mineraloil

aspetrol,diesel,keroseneandnaphtha,
all kinds of bulk chemicals and edible oils and fats.
In Port of Rotterdam region there are now five oil
refineries,whichprocesstheimportedoil,andover45
chemicalcompanieswhichhave largescalefacilities.
Thereisalso1500kmofpipelinesinterconnecting
oil
and chemical companies
(http://www.portofrotterdam.com).
This paper is investigating the determinants of
operational efficiency at chemical cargo terminals.
As it is well known that during loading and
unloadingoftheliquidchemicals,operationalsafety

Saull,185:2009); while filling, in

TheproductshandledinthejettiesofVOPAKand
OIL Tanking are mostly mineral oils and this is the
reason why these jetties are convenient for ships
between 2.000 and 200.000 dwt. VOPAK is also

of the jetties of these two terminals, handling
operations are usually realized with the barges and
only hoses are used in handling operations. The
mineral oils can behandledup to 2000 cbm/hour in

5.2 Intermodallogisticscapabilitiesofthecompanies;
TheEuropean railway network isdirectly connected
totheterminalsinHamburg and thereforeis avery
flexible instrument for transports leaving Hamburg
andarrivingattheterminalsfromthehinterland.All
three companies in
Hamburg have their own
locomotives and railway inside their terminals. The
yearly average number of wagons handled in OIL
Tanking is 20.000. Also this number in VOPAK is
daily between 100200 wagons. As a result, the
amount of handled liquid by railway is more than
seaborne transports in these two
companies 26% of
the products leave DOW / Hamburg terminal by
railway.

Allthe terminalsuse automatichandling systems in

The three Hamburg located terminals use full

Especially railway intermodal mode affects the
operational efficiency positively in terminals and
doesn’t require labor force like road mode.
InvestmentsonupperstructureinthiscasebyEastern
EuropeancountriesandTurkeyandintegrationwith
Western European countries would increase the
capacityseriously.
Determining
the specific criteria for the tanker
drivers to enable them to do loading operations in
automatic stations without terminal staff and
applying them widely would affect the operational
efficiencypositively.
Making use of simulators by training the
operational staff would give the personnel a visual
293
memory which would be helpful them during the
operationalactivities.
Allowing the customers to enter the terminals
software within the framework and to make their
own handle plan with the terminals planning
department can help the planning department in
makingoperationalplans.
