Patented Ship Hull

The Ecology of the Patent

In future, the reduction of energy and emissions (NOx / CO2) is more and more vital to ensure the economic operation of a vessel.

  • Ship owners are forced to retrofit their fleets as to be permitted to enter ports and seas.
  • The upgrading of alternative propulsions or energy carriers is cost intensive.
  • Cost pushing sulfur- and soot particle filter.
  • Quality controls for the heavy oil procurement (e.g. less residues).
  • Slow-streaming to avoid higher consumption values results in lower circulation.
  • Avoidance to purchase emission certificates.

The patented Lindinger hull saves up to 10 % of fuel costs and yields additional synergy effects.

The consequence is the saving of emissions (NOx, CO2).

Ecology is the impulsion of economy!

The economy of the Patent

Savings per vessel: The calculation of operating costs changes significantly, as the direct operating costs – here heavy fuel oil – account for up to 70 % of operating costs.

Model Calculation I

An original vessel, as the calculated model ship V 31.1 (Feeder ship of 200m) has an average consumption of about 40t heavy fuel per day at a CWL of 10m and 18 knots.

The usual calculation reads that a vessel is used 300 days per year. The stock exchange price per ton of heavy fuel (MGO, low sulfur, in Mar 11, 2019 , at Rotterdam), sums up to 582.50 US$, at a minimum order of 1,000 t.

A ship has a life span of approximately 25 years. This results in energy costs at 582.50 US$ per ton to about 175 million US$, for a 40t consumption on 7,500 days, in these 25 years.

Taking into account the patented Lindinger hull, the ship owner saves already for a planned new ship costs of:

ca. 17,460,000 US$

Model Calculation II

Example: Container Ship of 400m

Possible annual savings by the patented Lindinger hull (annual consumption)

Average consumption of the ship type 400m 300t per day
Average use 300 days per year
Costs of the heavy fuel IFO 380 per ton at Rotterdam
Mar 11, 2019
408,00 US$
Annual consumption 90,000t
Energy costs (without emissions) US$ 36,720,000
Savings potential at a daily consumption of 300 t for 300 days /year, is 408,00 US$ per ton:
These values are subject to the heavy price fluctuations at the crude oil stock exchange.
