Boil-off rate (BOR) – The amount of liquid that is evaporating from a cargo due to heat leakage and expressed in % of total liquid volume per unit time. Typical BOR. Boil-Off Rate. OECD. Organisation for Economic Co-Operation and Development. IEA. International Energy Agency. SCT. Single Containment Tank. DCT. During transportation, the leakage of boil-off gas (BOG) along wit. carrier has a nominal LNG boil-off gas rate (BOR) of 0.15% of cargo capacity per day [2]. May 17, 2017 of boil off gas (BoG) and recording of data for the purpose of monitoring of fuel The natural Boil-off rate (BoR) is the amount of liquid that is A great tool for calculating boil off rates! Now you will end your boils with the perfect volume every time. Every brewers system is a little different and dialing in your total heat transfer rate and Boil-off Rate (BOR). The result shows that the calculation model and simulation are feasible with typical LNG fleet specification and In the case of ships using liquefied natural gas fuel, either partially or completely, the amount of Boil-off Gas.

The evaporating gas (boil-off gas, BOG) is the main products in relation to the electricity generation, and the evaporating rate (boil-off rate, BOR) determines the efficiency of regasification and electricity generation. Therefore, estimating the BOR accurately can facilitate the utilization of BOG and improve the economic benefits of FSRU. Wilhelmsen Technical Solutions passed a milestone by successfully completing the gas trial for the first LNG carrier built to a Boil Off Rate (BOR) of 0.08% per day. WTS subsidiary company Ti Group completed the test on the LNG carrier Seishu Maru , currently under construction at Mitsubishi Heavy Industries in Japan for NYK Line. And an addition, I have read some article that said According to International Maritime Organization (IMO) requirement, BOR (Boil-Off Rate) for 125000 m3 membrane LNG carrier is 0.12% kg/kg per day. With typical value of 0.1% to 0.15% kg/kg per day depending on the insulation properties and sea conditions. For Approach 4, the BOR and overall heat transfer coefficient are 0.0919% and 0.0674°W/m2°C. When the thickness of the insulation barrier is increased to 400°mm, these initial values are reduced to 0.0631% and 0.0453°W/m2°C. An algorithm for optimal operation of BOG (boil off gas) compressors in a LNG gasification plant is proposed in this paper, which uses an empirical BOR (boil off rate) model, a MILP (mixed integer linear programming) formulation, and a simplified dynamic tank model. The BOG is the quantity of liquid that changes to the gas phase, and the boil-off rate (BOR) is dependent on the tank surface area, its heat conductivity, fuel thermodynamic state, and the temperature outside of the tank .
What is Boil-Off Rate (BOR) guaranteed by GTT? The design BOR corresponds to the amount of heat transferred to the tank under IGC code design temperature conditions (ambient air temperature = +45°C, sea water temperature = +32°C) with its insulation under a thermal steady state.
The design boil-off rate (BOR) used in the design is 0.05% in volume per day. The inner tank has a diameter of 84m and the thickness of shell insulation is
The "Boil off rate" usually refers to the amount of liquid vaporized by heat leaking into the tank per unit time. So in your case o.25% of the liquid will be boiled off per unit time. Usually the time is per day, but your percentage is much lower than those shown by Air Liquide for their tanks so I think your unit of time might be hour.
