Sep 20, 2021 · Vessel not resting on concrete saddles. There is a horizontal flare KO vessel (dia 4 mtrs) which was designed in a unique way and installed wrongly. The vessel was designed to be resting on 180-deg concrete saddles and had lugs designed to be bolted on top of those saddles. During construction (approx 12 yrs ago), the foundation sides were Learn More
The heat production cost of boiler wood pellets, wood chips and straw are lower than 35 EU/MWh. The heat production cost of electrical heat pump is around 37 EU/MWh. The heat price of the boiler straw is the lowest one, below 25 EU/MWh. The heat price of natural gas boilers in Denmark can be the highest one, higher than 60 EU/MWh.Learn More
