Meeting industry’s demand for ever growing LCO2 carriers and highest cargo volumes, voestalpine Grobblech presents the most efficient answer based on carbon steel.
As steel grades like yield type 355 considerably limit the efficiency of the tank design for low pressure application, voestalpine Grobblech established the new concept of F460 TMCP toughcore.
By utilizing the outstanding combination of strength and fracture mechanic properties at a design temperature of -60°C even in the heat affected zone, the cargo volume to tank weight ratio can now be maximized without significant changes in hull structure of the ship.
The increased ultimate tensile strength of minimum 580 MPa allows for an increased tank capacity of up to 40% with equal material thickness. Just in line with “economy of scale”, larger vessels come with lower operation costs related to the energy consumption per transported volume unit.
This has been evaluated on two different vessel design scenarios by our partner HB Hunte Engineering GmbH.
Significant advantages, which allow for an enhanced economic and ecologic life cycle approach.
Together with the recent development of F550 TMCP toughcore for medium pressure design, voestalpine Grobblech offers a comprehensive portfolio for the aspiring CCUS value chain.
With this further step, we are leading the way to remarkable reduced total cost of ownership and enhanced sustainability.
Whatever one pays for a ship with yield type 355 tanks, it is 20 to 40% too much compared to a ship with high-strength tanks when calculated over the ship’s lifetime.
