摘要:
A method and a vessel for offshore oil loading, wherein the vessel comprises a number of center tanks (3) arranged in the longitudinal direction of the vessel, and a number of wing tanks (5, 6) located in pairs on either side of respective center tanks, a loading line (19) being connected to the center tanks (3) via respective valves (20), and adjacent center tanks (3) being connected to each other via bulkhead valves (18). The method comprises the steps of a) firstly effecting filling of a desired number of the center tanks (3), these being substantially narrower and having a correspondingly smaller volume than the wing tanks (5, 6), b) thereafter opening bulkhead valves (17) between a center tank (3) and an appurtenant wing tank pair (5, 6), and sluicing out oil from the center tanks (3) into the two wing tanks (5, 6) by means of the static pressure from the center tanks, the bulkhead valves (18) between the center tanks (3) being open, so that the wing tank pair (5, 6) is filled as quickly as possible by suitable operation of the bulkhead valves (18) between the center tanks (3) and of the valves (20) of the loading line (19) to the center tanks (3), c) closing the bulkhead valves (17) of the two wing tanks (5, 6) when these and the appurtenant center tank (3) are filled to a desired level, and d) repeating the filling process according to the steps b) and c) successively for additional wing tank pairs (5, 6) after that all center tanks (3) have been filled again.
摘要:
A device for installation in a floating vessel which is intended for receiving a buoy or a turret in a submerged receiving space at the bottom of the vessel. The device comprises a tubular body (5) dimensioned for installation in a shaft (2) extending vertically through the hull of the vessel and which, at its lower end, is arranged to receive a module unit (6) provided with a through opening (8) for receiving the buoy/turret. When the module unit (6) is installed in the tubular body (5), the module unit at its lower end forms a seal (37) against the tubular body (5), and at its upper end the module unit (6) is fixed in relation to the tubular body (5) by locking means (40).
摘要:
A system for transferring oil from an offshore tanker to a platform. The system comprises at least one flexible hose (4) which is adapted to direct transfer of oil from a supply means (7-10) on a deck (2) on the platform (1) to the tanker (58) in question, and a number of hose handling stations (3) which are distributed around the circumference of the platform deck (2). Each station (3) is provided with a coupling unit (15) which communicates with the supply means (7-10) and is arranged for connection or disconnection of an end (11) of the hose (4), and a handling means (18-22, 24, 25) for lowering or hoisting of the house end (11) to/from the surface (5) of the water around the platform (1).
摘要:
A crude oil transportation system uses a dynamically positionable floating crude oil storage and offloading vessel and a dynamically positionable shuttle tanker. The dynamically positionable floating crude oil storage and offloading vessel is a self-contained unit including a flexible transfer hose for connecting to the production platform and a flexible discharge hose for connection to the dynamically positionable shuttle tanker.
摘要:
A vessel for use in offshore production or transport of hydrocarbons, and/or for loading/unloading of hydrocarbons, and/or for carrying out well operations. The vessel at its forward end is equipped with a submerged receiving space for receiving a bottom-anchored underwater buoy. A service shaft extends between the receiving space and the deck of the vessel. At the stern of the vessel, a coupling head is provided along with equipment for the connection of a hose for loading and unloading of oil.
