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 by scrubbers to be permitted to enter ports and seas.
- Upgrading with alternative propulsions or energy carriers (e.g. LNG) is cost intensive.
- Sulfur and soot particle filters that drive costs
- Slow-streaming to avoid higher consumption values results in lesser circulation.
- Avoidance to purchase emission certificates.
- Continuous strict environmental regulations concerning pollutant emission.
The patented Lindinger hull saves up to 10% of fuel costs and yields additional synergy effects as to the engine maintenance, emission protection and vibration.
The consequence is saving 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 3.1 (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 250 days per year. The stock exchange price per ton of heavy fuel (IFO380, low sulfur, in Mar 15, 2021 , at Rotterdam), sums up to 421 US$, at a minimum order of 1,000 t.
A ship has a life span of approximately 20 years. This results in energy costs at 421 US$ per ton to about 84 million US$, for a 40t consumption on 5,000 days, in these 20 years.
Taking into account the patented Lindinger hull, the ship owner saves already for a planned new ship costs of:
ca. 8,420,000 US$
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 (16m / 18 Kn) | 300t per day | |
| Average use | 250 days per year | |
| Costs of the heavy fuel IFO 380 per ton at Rotterdam Mar 15, 2021 |
421 US$ | |
| Annual consumption (To)) | 75,000t | |
| Energy costs (without emissions) | US$ 31,575,000 | |
| Savings potential at a daily consumption of 300 t for 250 days /year, is 421 US$ per ton: | ||
