25 000 DWT Stainless Steel Chemical Tanker
This FKAB design is 28,000 m3 with 25,000 DWT, and is a TIER III tanker for chemicals (IMO II and
III). The hull form is optimized for low fuel consumption and designed for excellent performance
in harsh weather conditions and can operate in Sulphur Emission Control Areas (SECA). A
shaft generator is installed with a frequency converter to save fuel costs in normal sea going
conditions. There is a pipe trunk above the main deck were all cables and pipes located inside to
ensure low maintenance cost.
The vessel is divided into 14 cargo tanks, 2 cargo tanks dedicated as slop tanks , consisting of
14 cargo segregations. Cargo capacity with a density of 1,54 ton/m3 and 1,85 ton/m3 when partly
filled. Two cargo tanks are dedicated for slop tanks in accordance with the rules.
The tanks are stainless steel in ferritic-austenitic steel, type 2205 with a molybdenum content of
min 2.70%. The vessels primary fuel is LNG (MDO if required) and compliant with IMO SOx Tier III
NOx emission limits. Manning is based on a crew number of 18 people in single cabins.
The propulsion system consists of one 4 stroke medium speed diesel engine directly coupled to
the controllable pitch propeller. Main engine and Auxiliary engines will use box cooling systems.
“Take me home” is handled via a hydraulic motor coupled via shaft generator in PTI mode. The
shaft generator is connected via a frequency converter allowing optimum propeller rpm at
