	Aloha, A marine oil transfer terminal loads Naphtha and un-loads Diesel Oil, Gasoline, Kerosene and Crude Oil. Now the current transfer is done via a number of Marine Hoses. I am tasked wit replacing the Hoses with applicable MLA(Marine Loading Arms). Should the sizing of MLA's be based on the pumping Capacity off Vessel or should it be dictated by the Oil Refinery. I have never sized MLA's so I if you have some good comments by all means please do share them. Thx dejand9

	It should be dictated by the maximum flow rate of the densest material the the line will ever carry. Get some professional help. Oil spills are costly.

	When I was working at a marine/rail terminal in the not to distant past we used to base the loading arm max capacity on the weight of the transfer hose filled with product taking into consideration the weight of the heaviest product that would be transferred and multiply that combined total weight by 4. This calculation was based on guide lines in the OPA (Oil Pollution Act) manual and the SPCC (Spill Prevention, Control, and Countermeasures) Manual. You really should contact the AHJ (Authority having jurisdiction) in your area such as the Coast Guard MSO (Marine Safety Officer) Office. You can also Google "Marine Transfer Hose Boom Hoist" or "Marine Transfer Hose Loading Arm" Contact one of the companies that best meets your needs and they can help you come up with the appropriate boom hoist for your facility/application. In any case, run it by your AHJ to be sure you are in compliance. Good Luck EDIT - Ya just like Lyn was saying. __________________ The first 5 days after a weekend are always the hardest................................
