(Ålesund/Gamlem, 14 September 2015) Ulmatec Pyro presents the biggest change in energy efficiency since the shift from steam to diesel propulsion machinery, made possible by expanding the utilities within the Pyro™ Waste Energy Management System.
Ulmatec Pyro´s focus and promise the last five years has been to mobilize waste energy on board vessels and rigs.
“Simply put, we are helping our customers to recover otherwise wasted energy, instead of using high-grade energy in the form of oil or gas,” says Managing Director of Ulmatec Pyro, Mr Jan Petter Urke.
Previously in 2011, when Ulmatec Pyro launched the Pyro™ Waste Energy Recovery System, the company claimed that only 30 - 40% of the energy produced on board as ship normally is used efficiently, and that 60% of the waste energy easily can be utilised.
“Now, in 2015, after delivery of more than 80 waste energy recovery systems, we know that 60 – 75% of the waste energy can be utilized, and we dare to say that this is the most important energy saving invention since the marine industry moved from steam engines to diesel engines,” claims Jan Petter Urke.
• Steam engines, 1800 - 10-15% efficiency / utilisation
• Diesel engines, 1900 - 30-40% efficiency / utilisation
• Diesel engines + Waste Heat Recovery, 2011* - 40-60% efficiency / utilisation
• Diesel engines + Waste Energy Management, 2015** - 60-75% efficiency / utilisation
Mr. Urke continues; “We see a great many opportunities for huge savings by transferring energy consumption from electricity to waterborne heat.”
“The Pyro Waste Energy Management System, which utilises waste energy from engine cooling and exhaust systems, can be used for a variety of purposes to enable substantial fuel and cost savings to be made, in addition to the major environmental benefits. Among our latest developments is a system generating clean emission-free electricity from waste heat recovery, and a flexible and cost-effective cooling system,” says Jan Petter Urke.
The Pyro Waste Energy Cooling System represents an efficient way of cooling of a vessel, giving the possibility to both reduce the number of pumps on board, and reduce the total pump effect in kilowatt’s (kW). 1 kW reduced pump effect equals 2000 litres of fuel per year.
“If the vessel needs 15.000 kW of cooling effect during a year, you can save as much as 100 kW in reduced pump effect with our system, which equals around 200.000 litres of fuel a year.” This is made possible by using a fewer number of pumps, and by the control of automatic regulated valves, which pumps strictly the required volume and flow of cooling water.”
“Marine gas oil price is going up and down. Currently the cost is about US$500 per tonne, and has been up to US$ 960 per tonne, but is expected to increase dramatically the next ten- to twenty years. This has a huge impact, both on running costs, and emissions to the environment,” concludes Managing Director of Ulmatec Pyro, Mr Jan Petter Urke.
Waste Energy Recovery System (heat recovery)
The system that recovers heat or energy from power suppliers like the propulsion system, cooling water, exhaust etc., and supplies it to energy consumers like:
• Heating of accommodation
• Cooling of accommodation
• Fresh water production
• Sanitary hot water
• Tank heating
• Tank washing
• Ballast water treatment
• Pre-heating of engine at standstill
Waste Energy Cooling System (seawater/freshwater cooling system)
This system gets rid of the energy produced by the machinery, which not can be exploited in the Waste Energy Recovery System (cooling by the help of seawater).
Waste Energy Power Generation System
Clean, emission free energy by converting engine waste heat to electricity (jacket cooling and exhaust).
