8 000 m3 Chemical and Oil Product Tanker
The FKAB I14 design is a bitumen, chemical and product oil tanker with independent cargo tanks for bitumen and asphalt with a temperature of up to 250°C. The vessel is designed with single bottom and double sides for ballast water.
The high temperature variations requires special design considerations; mainly because of thermal expansion of tanks and pipes. The cargo tanks consist of two blocks, forward and aft of the pump-room, with five and four tanks respectively in each block. Each tank block is only fixed in the middle and therefore able to move longitudinally, depending on the temperature. There is no structure inside the cargo tanks.
Propulsion is provided by a medium speed diesel engine with a gear and shaft generator coupled to a CP-propeller. Take me home device through PTI from the auxiliaries.
In order to save fuel the shaft generator id connected via a frequency converter allowing optimum propeller rpm at various speed.
