Tank truck to marine vessel - Oil transfer
8. Transfer Hoses

Table of Content

There are many characteristics of transfer hoses that need to be considered.

Hoses must be properly:

Hoses should be a single length from tank truck to vessel. If more than one length of hose is required then special precautions are necessary to minimize risks.

8.1 Material

Cargo hoses must be constructed of material suitable for the product being carried. When used in a marine environment, hoses must have a bursting pressure of at least 4 times their maximum working pressure.

8.2 Inspection

Hoses must be visually inspected before each use, checking for signs of wear and fatigue. Do not use hoses that appear to be in poor condition.

8.3 Testing

All pressure hoses must be hydrostatically pressure-tested at least once per year, to at least 1½ times their maximum working pressure; the hose must bear a test tag showing the date, test pressure and name of the person or company carrying out the test. More frequent pressure-testing is encouraged.

Hoses should also be tested for electrical continuity when they are pressure-tested.

8.4 Protection

When in use, hoses must be protected from damage: do not allow hoses to be driven over, dragged over sharp objects, or damaged in any other way.

Hoses must not lay in the water where they can be damaged by marine traffic, floating logs, or pinched between the vessel and the dock.

8.5 Tidal Action

Hoses must be of suitable length to allow for tidal variations without being stressed. The time required for oil transfer, and the estimated tidal action must be accounted for.
