Hi,
My company is in discussion with a supplier for compressed air cylinders of approx. 150-250 litres volume, 170 bar operating pressure. They will be going onboard a ship for a non-propulsion non-critical subsystem.
Contractually, the cylinders need to be built to or exceed Lloyds Register Rules for Ships standards (specifically, Part 5, Chap 11), but do not need to be certified at that.
The supplier is suggesting that building to Lloyds would be much more expensive, and is suggesting building and certifying to ASME, only because ASME pressure vessel codes are so much better known. We are comfortable with ASME, but we don't know the differences between ASME and Lloyds.
Is there any body familiar enough with both of these codes who could tell me if they are similar enough that an air cylinder designed and built to ASME would also, from a design point-of-view, meet Lloyds Rules requirements?
Thanks.
