Embodiment Construction

[0063] The embodiments of the present invention described below are only examples. In addition, it will be understood that the embodiments described below may be combined together. For example, a part of one embodiment may be combined with a part of another embodiment. Furthermore, it will be understood that the embodiment described below is not the only embodiment of the present invention.

[0064] figure 1 A floating unit 100 suitable for the production and storage of hydrocarbons on water is shown. The floating unit 100 is intended to be used in marginal oil and gas fields where the volume of hydrocarbons produced is relatively low. Therefore, the floating unit 100 has a relatively small hydrocarbon storage capacity of 100,000-300,000 bbls.

[0065] The floating unit 100 includes a hull 110 having a bottom portion 112 submerged in the water 10 and a top portion 116 located above the water 10 when the floating unit 100 floats on the water 10. It will be understood that the si...

Abstract

A floating unit for producing and storing hydrocarbons has a compartment and an opening that allows water flow into and out of the compartment. The unit is arranged to selectively control water flow into and out of the compartment and hence control the level of water in the compartment. By allowing water flow into and out of the compartment and controlling that flow, the weight of the floating unit can be controlled and hence the draft of the floating unit (i.e. extent to which the floating unit is submerged in the water) can be controlled. That is, the depth at which the floating unit sits inthe surrounding water can be controlled via the amount of water in the compartment. Because the draft of the floating unit affects the stability (i.e. the heave, pitch and roll) of the floating unitin the water, controlling the draft of the floating unit enables the stability of the floating unit to be optimized.

Description

Technical field [0001] The invention relates to a floating unit and a method of stabilizing the unit. For example, the present invention relates to floating units for the production and storage of hydrocarbons. Background technique [0002] Marginal offshore oil and gas fields pose various challenges to operators. It may have low reserves, uncertain reserves or low production. These make the development of fixed platforms or conventional Floating Production Storage Offtake (FPSO) commercially unattractive. It may also be in deep waters or where seabed conditions make jack-up or fixed pile-supported platforms undesirable. [0003] Currently, FPSO units are used for larger and more economically attractive field development. Almost all FPSO units are based on the reconstruction or new construction of oil tankers, which are "boat-shaped" vessels designed to provide the most economical way to transport oil. However, this tanker is not designed as a fixed unit that has been parked f...
