Abstract: The traditional semi-submersible column configuration remains unchanged, while the present method focuses on configuring the pontoons of a semi-submersible hull structure. This approach highlights simple geometry, low platform draft, minimal vertical motion, and optimal hull steel weight for simple regular SCR applications. It aims to deliver a streamlined design, expedite construction, facilitate rapid assembly, and ensure hull compatibility with SCRs, ultimately enhancing efficiency and improving the economic feasibility of deep and ultra-deep water development projects.

Abstract: The present disclosure provides a system and methods for providing responses to user provided questions that are grounded in the user's browsing history and enables searching of the history for resources previously viewed based on the content of the resources. In one example embodiment, a portion of a query is received. A query suggestion relevant to the portion of the query is obtained. A resource from a history repository relevant to the portion of the query is identified by obtaining a semantic representation of the portion of the query, and identifying a semantic representation of content associated with the resource from the history repository. The semantic representation of the content includes a similarity score with the semantic representation of the query that satisfies a threshold. A resource suggestion is generated for the resource. The query suggestion and the resource suggestion is provided as selectable query completions.

Abstract: The method for counterbalancing the mean inclination of a Floating Offshore Wind Turbine (FOWT) platform is designed to be simple, efficient, and highly responsive. It employs short-distance piping to enable swift and effective pump-in and pump-out operations within the same column, allowing for precise and independent control of ballast operation. This strategy is not only cost-efficient but also supports remote operation, facilitating rapid adjustments for both normal and abnormal conditions. Furthermore, the method incorporates redundancy in the counterbalancing systems, significantly boosting the overall reliability and ensuring consistent and effective ballast management for the platform.

Abstract: A floating structure foundation for a wind turbine features several improvements, including a transition assembly that supports the wind turbine generator (WTG) and tower centrally, transferring loads to primary structural components to maximize efficiency. Its highly modular design allows for flexible construction and scalability, with each component built independently for easier adaptation to different project requirements and site conditions. This modularity supports efficient dry transport, enabling multiple modules to be shipped simultaneously on various vessels. The foundation offers a simplified design with accelerated construction, rapid assembly, and installation.

Abstract: The present invention provides a method and a system for processing session data in an interactive process, a server group, and a computer readable storage medium. A memory module and a protocol configuration module are configured in a gateway server, keywords can be directly extracted by the protocol configuration module from a session of a client and a feedback session of an interactive logic server, and then the keywords can be directly forwarded, so that the throughput of session data processing is improved. The corresponding data is stored, extracted and forwarded by using the memory module, so that the delay of data transmission is reduced. Because the memory module is arranged in the gateway server, the occurrence rate of interface instability can be reduced.

Abstract: Highly uniform Fabry-Pérot-based optical ultrasound transducer arrays can be formed on a substrate by surface-micro-machining, using a sacrificial material layer to define the length of a Fabry-Pérot cavity formed between two partially optically reflective layers, and thereby set the optical resonance wavelength of the cavity. The transducer elements of the array can be interrogated in parallel with a laser operating near that resonance wavelength. Various techniques are available to tune the optical and acoustic properties of the transducer elements.

The method also includes, in response to validation of the network message, converting, by the event gateway, the network message to an event and publishing, by the event gateway, the event to the message bus, thereby providing the event associated with the network message to a service to which the network request is directed.

Abstract: Embodiments of this application provide a trip prompting method and apparatus, applied to a first terminal. The first terminal may obtain trip information. The first terminal may acquire a first duration associated with a trip start position. The trip information includes a trip start time and a trip start position. The first terminal may acquire a second duration required to arrive at the trip start position from a position of the first terminal at a first time. The first terminal calculates a first difference between the trip start time and a second time. The second time is a time after the first time passes the second duration. Therefore, when the first difference is less than or equal to the first duration, the first terminal may display, through a first interface, information for prompting departure. The first difference is less than or equal to the first duration, and the first duration is learned in advance.
