Efficiency of the JLMD System in figures.
The JLMD System efficiency is regularly studied by the company's technical team in order to better forecast and optimize the fuel recovery in case of incident at sea.
With the use of HFO 6 hydrocarbon (viscosity 615cSt at 50degC), different factors will have to be considered concerning the time devoted to oil; in particular, fuel temperature, length and width of FOR (Fast Oil Recovery) piping, and rescue action swiftness.
As an example, a ship equipped with the JLMD System and DN200 pipes, requires less than 4 hours to empty 100 m3 of fuel oil cooled at 15degC and at 200 m depth.
In the same context, at a depth of 50 m, the oil recovery will take only an hour and a half, which is 2.5 times less than for a wreck at 200 m.
Fuel recovery time can be shortened even more by injecting hot water into recovery flexible hoses in order to reduce head losses and increase the flow rate in the pipe.
With this technique, at 200 m depth, 100 m3 of HFO 6 will be recovered in less than half an hour - all other factors being equal.
Time saved on the recovery process, in case of such incidents as a breach in a bunker tank, limits operating losses that can sometimes be high due to the need for the halt of the ship for a certain time.
As a consequence, continuous cooperation with salvage companies in order to optimize our processes guarantees to our clients a quick and reliable solution to this crisis.
