Abstract: A rail system (40, 40?) of a ship (30) for positioning and arresting a hose (28) for supplying fluid material to an oil rig (10) from the ship (30) or supplying fluid material to the ship (30) from the oil rig (10). The rail system (40, 40?) comprises a rail (44, 44?, 46, 46?, 47) extending lengthwise at the upper edge of the bulwark of the ship (30). A vertical notch (48, 50) is provided in the rail having a bottom width corresponding to the diameter of the hose (28), and a locking element (52, 52?) of an elongated configuration being pivotally journaled adjacent to the vertical notch and being shiftable between a vertical position in which the hose (28) may be freely introduced into and positioned in the vertical notch (48, 50) and a horizontal position in which the locking element is blocking the entry into the notch and rests on the hose (28) for arresting the hose in the notch.
