Description

FUNDAMENTALS [001] The present utility model belongs to the technical field of oil and gas and, more specifically, to the field of underwater operations using Remotely Operated Vehicles (ROVs). [002] This utility model relates to a skid, which is connected to an ROV for subsea operations. A skid is a structure or platform used in the oil and gas industry, as well as in other industries, to mount and transport equipment efficiently and safely. Skids are designed as modular units that can be easily transported and installed, facilitating the movement of heavy and complex equipment and may additionally include subsea floats for high depths, in order to provide thrust to counteract the weight limitation of the ROV. A skid can support various types of equipment, such as pumps, compressors, filtration systems, generators and processing units, which are assembled and tested at the factory before being shipped to the installation or use site. The robust construction of skids allows them to be moved by cranes, trucks, vessels and other means of transport without disassembling the equipment mounted on them. Furthermore, skids simplify installation and maintenance, as most of the necessary components are already integrated into the structure, reducing the time and effort required on site. [003] In oil and gas exploration, skids are frequently used to support processing units, chemical injection systems, pumping stations, and other applications that require compact and efficient assembly. The use of skids is an efficient and versatile solution for assembling, transporting, and installing equipment in various industrial environments, providing flexibility and saving time and resources. [004] Patent document US2016258653 discloses a remotely operated vehicle-mountable hot water injection skid comprising a skid structure, one or more floats, a power interface, one or more subsea power transformers, one or more electrical power interfaces, one or more data communication interfaces, one or more skid heater telemetry systems, a predetermined set of integration equipment, a water collection and heating vessel, a pumping and circulation system, and a hot seawater circulation flying cable or spray stick that enables delivery of heated fluid directly to a subsea asset using heated seawater supplied via a common hot hydraulic system or directly via a pressurized spray stick. [005] Additionally, document US2016258235 discloses a system for installing a strip around a rigid subsea structure that includes an ROV having a main body. A set of extendable jaws beyond an outer perimeter of the main body is attached to the ROV. The system also includes an operatively coupled strip distribution system and a strip installation mechanism operatively coupled to the ROV. The ROV includes at least one main body and a skid. A strip system can be positioned on the skid coupled to the ROV. FUNCTIONAL IMPROVEMENT [006] Subsea tools or devices can be transported by skid from the surface to the location where they are to be used. A device, such as a subsea inspection device, can be attached to a skid in order to be transported to, for example, a subsea pipeline to be inspected. [007] However, conventional skids do not offer adequate support to accommodate specific device geometries, and adaptations to the skids are necessary so that such devices can be placed and transported. [008] Therefore, the present object is a new arrangement of a skid comprising a cradle, through which improved functional resting of a tool or device on said cradle is achieved. [009] This functional improvement increases the efficiency in the use of devices for underwater services, as it allows for greater convenience in positioning, resting and transporting the device on the skid. [010] Thus, a skid for underwater operations is disclosed comprising structural elements and a support for coupling to an ROV, the skid further comprising a cradle, wherein the cradle comprises: at least one seat; at least one sliding rod; at least one upper rail and one lower rail; and at least one double-acting hydraulic cylinder.
