Concept Study - Handysize Oil- Chemical Tanker

INEC made a concept study for a new handysize oil-chemical tanker design. The study is based upon the experiences from INEC's existing and successful design of a 19800 tdw oil- chemical tanker.

Motivation of the study

  • high demand for small sophisticated oil- chemical tanker in the maritime market

  • improvement of INEC's existing design of a handysize oil- chemical tanker based upon the experiences from the construction process and the feedback of the ships in service

  • new ideas and technical possibilities

  • new design tools such as 3D CAD

  • design of a modular platform with the possibility to realise individual owner demands

  • meet the today's and future class and environmental demands

Design targets of the study

Steel Structure

  • update of the steel structure according to the latest CSR revision (Common Structural Rules)

  • streamline the steel structure in the engine room to avoid edges and niches and optimise the foundation of the deck house above

  • improvement of the foundation of heavy components such as oil fired boiler, Diesel- generator sets, etc.

Engine Room Arrangement

  • reduction of the engine room volume to achieve a bigger cargo tank volume

  • reduction of noise level by separate rooms for

    • Diesel- generator sets

    • hydraulic power packs for cargo pumps

    • compressed air compressors

  • improvement of the engine room ventilation to avoid hot and cold spots

  • improved arrangement of components to achieve easy service and maintenance for an unmanned engine room

  • design of a modular engine room arrangement to meet different individual owner demands such as:

    • hydraulic or electric driven cargo pumps

    • two or four stroke main engine

    • shaft generator

    • nitrogen generator

    • etc.

Cargo Area

  • improved arrangement of cargo deck equipment such as

    • cargo pumps

    • cargo tank hatches

    • tank washing machines

    • fixed tank venting and drying ventilation

    • etc.

  • improved pipe rooting by using 3D design tools

Environmental aspects of the study

  • operation with regular or low sulphur HFO

    • two separated pairs of HFO storage, settling and service tanks

    • two cylinder oil storage tanks

  • Ballast water treatment to achieve the latest MARPOL regulations

  • high sophisticated vapour return system to avoid air pollution

Future Aspect of the study

  • totally diesel electric driven vessel with conventional shaft arrangement or POD drive

  • NOx reduction by using SCR (Selective Catalytic Reduction) or direct water injection systems

  • SOx reduction by using exhaust gas scrubber or low sulphur fuels

  • heat recovery
