With our latest Project, CAPPADOCIA SEAWAYS we are proud to complete our 25th scrubber installation. We are thankful to our valuable customers which have thrusted on us and gave us the chance of adding value to their good vessels.

 

 

System Information:

The scrubber system is designed to operate in three different modes, dry mode on compliant fuel, open loop mode and close loop mode. Each of these exhaust gas cleaning modes has its own unique way of operation for removing SOX from the exhaust gas. The scrubber system is called as hybrid design that is capable of operating in both open loop and closed loop modes. The wash water system design includes four water pump, two sea water pump, two circulating pump, two coolers, new sea chest in pump room, NaOH and Sludge tanks, process, 2 scrubber towers (8400 kWx2) tank and separator unit.

 

During the operation in open loop mode, the scrubber uses the natural alkalinity of seawater to absorb and bind the SOX from the exhaust gas. The alkalinity of seawater varies depending on geographic location, however at the most locations it is appropriate to use a value of approximately 2.5 mmol/L in Mediterranean and 1.2 mmol/L in Baltic sea.

 

During the operating in close loop mode, the scrubber recycles water in sodium hydroxide which is continuously added to balance pH at slightly alkaline value. When operating is closed loop mode, the scrubber system periodically discharges a quantity of wash water to reduce the build-up of sodium sulphates. The system is topped up with freshwater or seawater. For scrubbing, the gaseous SO2 can be removed with efficiencies close to 100%. The SO2 is converted to sodium sulphates and discharged to sea, which already contains much larger amounts of sodium sulphates.

 

By removing the SO2, formation of secondary aerosols and acid rain are avoided.

Preventive Actions Against Covid-19

Gemak is lengthening ro ro ships for U.N. Ro-Ro

Gemak is lengthening ro ro ships for U.N. Ro-Ro

It has been several years that U.N. RO-RO İŞLETMELERİ A.Ş. operating one of the most modern and effici
ent fleets of RoRo vessels started contemplating about increasing capacity and efficiency as well as decreasing environmental footprint of their fleet by lengthening their vessels. Decision has been made and Gemak Group has been chosen as business partner for this demanding project at the tender that was attended by major European shipyards.

Ships from the same series will be lengthened by 30 m. building of new midbody block having 1.130 tons has already been started. For block building, Gemak will use several of its facilities to ensure fast and high quality fabrication. Finally, it will be assembled in Gemak TGE Shipyard and launched from the slipway already outfitted to minimise down time of vessels during cutting and lengthening operations. The first ship is expected in Gemak TGE Shipyard at the end of the year. Besides lengthening, Gemak will reinforce existing hulls of the vessels due to increased longitudinal and slamming forces. Also modification of HFO tanks related to MARPOL requirements will be performed in the fore part of the vessels.

 

Besides proximity to U.N. Ro-Ro terminal that ships to be converted call regularly, most important reasons to make decision in favour of Gemak were its technical capabilities and   graving dock capacity in Gemak TGE Shipyard  that will be used to perform cutting and lengthening operations. Once the ship is dry docked all movements will be performed in dry condition.

 

“We will use our own SPMT’s to move lengthening section in the dry dock.” says Birol Uner, Gemak’s CEO. “More challenging task is moving of the forward part of the vessel after cutting, weight of which will exceed 4.000 tons. Nowadays, our R&D team is developing skidding system that will be used to move forward part of the ships for about 30 m. We will also use special positioners that were developed in-house for 3rd Bosporus Bridge project that we have completed recently. This piece of hydraulic PLC controlled equipment enables us to position heavy weights, such as lengthening section of for U.N. Ro-Ro vessels with precision of less than 1 mm. This will make our job much faster, easier and will also ensure good alignment and high quality performance. Projects like these make us develop our technical capabilities and increase our competitiveness. It complies with our commitment to permanently develop our facilities.  With these two projects we hope for more similar work from other ship owners. We will be able to offer very competitive price and short shipyard stay. “

 

Recently, starting from end of 2013, Gemak has embarked on capacity expansion programme focused mainly on heavy steel structures fabrication, handling of heavy loads and efficient and environment friendly blasting and painting of newly fabricated steel structures in closed and controlled environment. Most of the investment was put in place in Gemak’s new shipyard in Altinova (Yalova) region related to the project of steel decks’ fabrication for 3rd Bosphorus Bridge which are abt. 48000 tons in total. These improvements have continued and Gemak is nowadays investing in improving its piping and steel fabrication facilities aiming both shipbuilding and industrial projects.

 

Apart from being leader in ship repair activities in Mediterranean for many years, new capacities give Gemak Group opportunity to be very competitive in major conversions and steel fabrication projects.
