Frederiet Mergus & Ardea

4 700 DWT Bitumen carrier

The ratio between deadweight and certain geometrical requirements in a number of ports have been a main focus for the Frederic Mergus & Ardea design. To reach the required deadweight she has full body and a lot of emphasise has been on space effective internal design of cargo-, engine- and accommodation spaces onboard.

The Mergus & Ardea is designed to handle cargo with a temperature of up to 250°C. The high temperature variations requires special design considerations; mainly because of thermal expansion of tanks and pipes. The Mergus & Ardea has two tank blocks with four tanks in each. Each tank block is only fixed in the middle and therefore able to move longitudinal depending on temperature. Each tank block also has an integrated pump room. All cargo tanks are isolated.
