Modular system and method for controlling subsea operations
The invention concerns a modular system for controlling subsea operations. The modular system comprises a control room structure at a top side location, the control room structure is provided with a fixed modular connection assembly. The interior of the control room structure is prepared for accommodation f a set of replaceable control modules comprising at least one dedicated control module provided for controlling a corresponding operational well tool. The said set of replaceable control module(s) is selected in accordance with a chosen subsea operation for accommodation in the control room structure. The said set of replaceable control module(s) accommodated in the control room structure is connected to the fixed modular connection assembly for establishing communication between the at least one dedicated control module and its corresponding operational well tool. The invention also concerns a method for controlling subsea operations.
1. A modular system for controlling subsea operations, comprising:
a control room structure which is positioned at a top side location, the control room structure housing a fixed modular connection assembly;
wherein an interior of the control room structure is configured to accommodate a set of replaceable control modules comprising at least one dedicated control module for controlling a corresponding operational well tool, the operational well tool being configured to perform an operation on a subsea well and the said set of replaceable control modules being selected in accordance with a chosen subsea operation;
wherein the fixed modular connection assembly includes a plurality of connector members which are positioned on an exterior side of the control room structure; and
wherein the said set of replaceable control modules is connected to the fixed modular connection assembly and the corresponding operational well tool is connected to a corresponding connector member to thereby establish communication between the at least one dedicated control module and the operational well tool.
2. The modular system for controlling subsea operations in accordance with claim 1 , wherein the control room structure comprises a compartment unit having storage space for the set of replaceable control modules.
3. The modular system for controlling subsea operations in accordance with claim 2 , wherein the compartment unit is movably arranged in the interior of the control room structure.
4. The modular system for controlling subsea operations in accordance with claim 3 , wherein the compartment unit is movable between a storage position in which the compartment unit is positioned inside the control room structure and an access position in which at least a portion of the compartment unit is positioned outside the control room structure.
5. The modular system for controlling subsea operations in accordance with claim 2 , wherein at least one of the replaceable control modules is movable between a storage position in which at least one of the replaceable control modules is positioned inside the storage space of the compartment unit and an access position in which at least a portion of the at least one replaceable control modules is positioned outside the storage space of the compartment unit.
6. The modular system for controlling subsea operations in accordance with claim 1 , wherein the fixed modular connection assembly comprises at least one connection member having a standardized interface for receiving a connector of at least one line which communicates with at least one of the operational well tools.
7. The modular system for controlling subsea operations in accordance with claim 1 , wherein the fixed modular connection assembly comprises a hydraulic module and is configured for receiving signals from the replaceable control modules and transferring the signals as pressure signals to the operational well tools.
8. A method for controlling subsea operations comprising:
providing a control room structure at a top side location;
providing the control room structure with a fixed modular connection assembly and an accommodating unit for receiving and storing a set of replaceable control modules, the fixed modular connection assembly being housed in the control room structure and comprising a plurality of connector members which are positioned on an exterior side of the control room structure;
selecting the set of replaceable control modules in accordance with a chosen subsea operation, wherein at least one of the replaceable control modules is a dedicated control module provided for controlling a corresponding operational well tool which is configured to perform an operation on a subsea well;
arranging the set of replaceable control modules in the accommodating unit; and
providing a connection between the set of replaceable control modules and the fixed modular connection assembly and between the operational well tool and a corresponding connector member to thereby establish communication between the at least one dedicated control module and the operational well tool.
