Can You Get a Quote for a Replacement Floating Oil Hose Without the Original Drawing?

Yes. You can ask DeepSee for a replacement floating oil hose quote even if the original drawing is missing. Start with a legible photo of the hose markings and a note about where the section sits in the string. That is enough to open the inquiry. A firm quote needs a specification that both your terminal and the supplier can check.

I have the serial number and a photo. What else helps?

If your maintenance list says “16-inch floating hose,” tell us what each end connects to. One sentence such as “the first section between the buoy and the mainline” is more useful than a folder of unlabelled photos. If you know which section it is but not its English name, mark it on a sketch. Our floating hose range shows the names used for the different positions.

Send what you already have: the manufacturer’s name and serial number as marked, photos labelled End A and End B, or the hose line item from an old purchase order. These are clues to the original specification. If a marking is unreadable, say so. A serial number from another manufacturer does not, by itself, tell us how that hose was built.

Why does it matter which flange is at the buoy end?

In a public single point mooring (SPM) tender, Ceylon Petroleum Storage Terminals Limited specified a 16-inch first-off-buoy hose. The reinforced end at the buoy required a Class 300 flange; the opposite end required Class 150. The specification listed the hose’s rated working pressure separately. A request for a “16-inch hose with Class 150 flanges” would have identified only one connection correctly.

Those ratings belong to that particular tender. For your replacement, label the two connections and record the flange standard, class and facing for each end wherever they are known. Keep the hose working pressure in a separate field. If the photos do not settle a detail, flag it for confirmation rather than guessing.

What needs to be confirmed before I compare prices?

Ask each supplier to price the same section against the same document revision. If the original drawing cannot be recovered, use the terminal’s approved hose schedule or replacement specification as the starting point. Keep any differences visible in the quotation.

  •  The section: its position, bore, face-to-face length, service fluid, rated working pressure and carcass construction.
  •  The interfaces and operating requirements: each end connection and any specified bend radius, buoyancy or electrical continuity requirements.
  •  The scope and timing: quantity, accessories, required tests or witness points, destination and required arrival date. A factory dispatch date is different from the date your maintenance team needs the hose on site.

If you need a budget estimate while records are being retrieved, say so in your request. Ask which assumptions the estimate uses and which items could change the price or lead time. That gives procurement a figure to discuss without treating it as approval to install a substitute.

What can I send DeepSee today?

You can use the short request below. Leave unknown fields blank and include any records already available.
