CYE Petrol is the first and only physical bunker supplier in Turkey who is using mass flow meters voluntarily during bunker supplies.

Why Emerson Coriolis Mass Flow Meters?

Coriolis meters provide continuous, online measurement of mass flow rate, volume flow rate, density, temperature, and batch totals – all from a single device. Coriolis meters have no moving parts or obstructions in contact with the fluid being measured and require no maintenance, flow conditioning or straight pipe runs. Unlike volume measurement, mass measurement is independent of operating pressure and temperature, which negates the need for error-prone density conversions.

For highly viscous fluids where entrained gas and air is unable to escape, direct mass flow measurement can perform better than competing technologies such as volumetric meters and tank gauges.

History of CYE Petrol

CYE PETROL was founded on 12 May 1988 by C.Yalçın ERAYDIN

The company's first experience in business was her being involved in the petroleum products trade of Iraq with Europe during the Iraq - Iran war, through Turkey by the so called “truck pipe line” which started in Iraq and ended at terminals like Iskenderun and Mersin in Turkey.

CYE Petrol became a “Physical Bunker Supplier” in order to deliver bunker in Istanbul ports to those vessels passing Turkish Straits. She is the first physical bunker supplier established and located in Gulf of Izmit.

The company is a Physical Bunker Supplier of MGO and IFO grades since May 1992 in Turkey.

Bunker deliveries are managed professionally by a bunker barge fleet under CYE Petrol's control.

Until 2006 the Company was outsourcing the bunker barge deliveries.

In 2006 the Company decided to reshape the bunker barge fleet's under her control. The number of outsourced bunker barges were decreased.

In 2009 well equipped bunker barges with higher technologies, better performance were introduced for bunker deliveries. The company obtained the advantage of supplying high quality product to more vessels, with larger volumes in most time efficient way.

In 2013 CYE Petrol decided to invest in double hull, environmentally friendly new generation bunker barges.

In May 2014 first of new generation bunker barges M/T BEYKOZ-E (1805 dwt) launched.

In November 2014 sister new generation bunker barge M/T KALAMIS-E (1805 dwt) launched.


In 2015 all bunker barges under CYE Petrol’s control were fitted with Emerson Coriolis Mass Flow Meters.

During 2015 CYE focused on operational infrastructure as much as training. With the elimination of incompatible staff with company’ dynamic process, CYE’s operations became more efficient.

All these infrastructure and human resource investments paid off. During 2013-2017 Istanbul bunker market increased sales volume 100%, from 1.4 million MT to 2.8 million MT. During same period, 2013-2017 CYE Petrol increased her sales volume 280%, 190 000 MT to 530 000 MT.
