A mobile oil platform has a vessel for holding oil, a subsea hose connected to a subsea well, a pump mounted on the vessel for detachably connecting to the subsea hose and one or more floats connected to the subsea hose by cables, wherein the hose is connected to the vessel, and when detached the floats hold the hose in the water. A method of hose management is described, having the steps of retrieving one or more floats connected to a hose by cables, pulling the cables from the sea to retrieve the hose, and connecting the hose to a platform. The hose may be disconnected and dropped in the water wherein a float marks a hose position. Further, probes may be deployed to suck the oil/water mixture into a separator.
Une plateforme pétrolière mobile est dotée dun récipient pour contenir du pétrole, dun tuyau souple sous-marin relié à un puits sous-marin, dune pompe fixée au récipient reliée de manière amovible au tuyau souple et dun ou de plusieurs flotteurs reliés au tuyau souple par des câbles. Le tuyau souple est raccordé au récipient et lorsquil est débranché, les flotteurs le maintiennent dans leau. Un procédé de gestion de tuyau souple est décrit comportant les étapes de récupération dun ou de plusieurs flotteurs raccordés au tuyau par des câbles, de retrait des câbles de la mer pour récupérer le tuyau et de raccordement du tuyau à la plateforme. On peut débrancher le tuyau et le laisser tomber dans leau, un flotteur marquant sa position. De plus, il est possible de déployer des sondes pour aspirer le mélange deau et de pétrole dans un séparateur.
1 . A mobile oil platform, comprising:
a. a vessel for holding oil;
b a subsea hose having an open end configured to engage with the
platform, and an opposite end connected to a subsea well;
c. a pump mounted on the vessel configured to detachably connect to the
subsea hose to pump oil into the vessel;
d. one or more floats connected to the subsea hose by a cable configured
to hold the end of the subsea hose,
wherein the subsea hose is detachably connected to the vessel and when full,
vessel detaches the subsea hose such that the floats hold the subsea hose in
and the full vessel is replaced by an empty vessel.
2. The mobile oil platform of Claim 1, further comprising.
a two relief vessels; and
b. oil transfer hoses connecting the platform to each of the
wherein the relief vessels are configured to receive oil from the platform
the oil transfer hoses.
3. The mobile oil platform of Claim 1, further comprising surveillance
mounted on the floats to ensure the security of the subsea well and to monitor
4. The mobile oil platform of Claim 1, wherein the open end of the subsea
when detached from the platform to prevent the spilling of oil.
5. The mobile oil platform of Claim 1, wherein the floats are gas bags.
6 The mobile oil platform of Claim 1, wherein the floats are constructed of
7. The mobile oil platforrn of Claim 1, further comprising-
a. a probe; and
b. a hose connecting the probe to the pump,
wherein the probe is contigured to vacuum an oil/water mixture into the
using the pump.
8 The mobile oil platform of Claim 7, further comprising:
a. a separator; and
b a water evacuation valve,
wherein the separator is configured to separate the oil/water mixture, and
the water through the water evacuation valve.
9. The mobile oil platform of Claim 7, further comprising a camera attached
probe, wherein the camera is configured to allow the probe to be remotely
10. The mobile oil platform of claim 1 further comprising.
a. a submersible; and
b. a hose connecting the submersible to the purnp,
wherein the submersible is configured to vacuum oil/water mixture into the
platform using the pump.
11 The mobile oil platform of claim 10, further comprising a camera
attached to the
submersible, wherein the camera is configured to allow the submersible to be
12. The mobile oil platform of Claim 1, further comprising a winch
retrieve the subsea well hose for attachment to the platform and lower the
detachment from the platform.
13. A method of retrieving and attaching the subsea hose to the mobile
claim 12 comprising:
a. retrieving one or more floats connected to the subsea hose by a cable,
b. detaching the cable from the floats,
c. connecting the winch to the cable;
d pulling the cable from the sea to retrieve the subsea hose using the
e. connecting the open end of the subsea hose to the platform.
14. A method of detaching the subsea hose from the mobile platform of claim
a. detaching the subsea hose from the platform;
b. attaching the cable to the subsea hose;
c lowering the subsea hose into the water with the winch; and
d. reattaching the cable to the floats,
wherein the floats mark the position of the subsea hose in the water
