... and industrialization of FOWT technologies to reduce cost and improve 814 efficiency. Generally there are three types of ports based on their functions (CSLC, 2023): Manufacturing and Fabrication (M&F Port) Staging and Integration (S&I Port, Marshalling Port, Staging Port) Operations and Maintenance (O&M Port) M...

... and product compositions, the well jumpers, infield flowlines, and production flowline consist of flexible, carbon steel, and internal CRA lined flowline sections. This paper presents the flowline design, fabrication, and installation challenges encountered during the project execution, discusses the steps...

... that requires less steel to construct. Due to its small base dimension, regular section geometry much more even distributed weight on skid beam, fabrication of CPT is relative easier. Unlike conventional platforms that are designed to resist forces, the compliant tower is designed to flex with the forces...

... ABSTRACT Cylindrical leg is an essential structure of jack-up rig, and its fabrication accuracy will influence the operation cost and service lift of offshore structure. Concentrating on the dimensional deformation caused by rack and cylinder welding, the experiment to fabricate the leg...

...) was found to be a cost effective and robust alternative. A HSF is a mudmat with four corner piles that provide additional bearing capacity in an effective and cost competitive way. This paper presents the design process, fabrication, and installation of a HSF for two flowline end terminations (FLETs...

.... the maximum sub-component dimensions) will be presented to define the boundary conditions for the design process. One focus is on the serial fabrication procedure which will be presented as well. The paper will also compare the updated concrete design with prior steel designs to highlight the improvements...

..., as shown in Fig. 1, both rigid jumpers have been used extensively over the last decade for both first- and second- end pipeline connections. The rigid jumper or spool piece is a measured and fabricated steel piping component that connects subsea structures with diverless connectors on each end. Rigid...

... Abstract HZ25-8 DPP is the second heaviest topside and the first topside installed by DP floatover in China. The topside need to be fabricated separately from DSF because of the DSU that located between the topside and DSF and also need to be arranged longitudinally along the skidway due...

... of the relevant techniques and experiences are summarized and discussed in this paper. constraint wave period 5 subsea production equipment jumper constructability jif jumper upstream oil & gas jumper installation subsea system jumper design installation py34-1 cep fabrication operation...

... Abstract LW3-1 CEP Topside plus Deck Support Frame (DSF) total weight reaches 32000 tons, is one of the Largest topsides in the world. The CEP Topside and DSF is fabricated separately due to existence of Deck Separate Unit (DSU). They are combined after fabrication by load transference method...

... Abstract In offshore platforms, the need of multi-mode fiber and single-mode fiber exist at the same time for condition monitoring. In order to use those fibers simultaneously, photonic lantern is designed. However, complicated fabrication process and lack of study about response of parameters...

... of welded pipe test specimens. It is imperative that the specimens be fabricated with materials of known properties and that all possible measures be taken to limit variations from the intended specimen design. It has been observed that unexpected results are often due to irregularities in pipe material...

... is connected with two production wells, and considering the commercial benefit of client, one spare hub and four spare valves are provided in the manifold system for the future wells. During the design fabrication and testing, there are lots of challenges. In the paper the design fabrication and testing...

... ABSTRACT Decisions made during planning, design, fabrication, construction and installation of a pipeline project will influence how good the integrity management will be. The operator can use different integrity management systems, but he cannot change what is built and installed, at least...

... ABSTRACT In fabrication process of offshore structures, it is needed to lift the crawler crane down to the dock to perform erection work in some cases. In conventional way, the crawler crane shall be taken apart prior to lifting down to the dock, and then assembled together, which...

... ABSTRACT LW3-1 CEP jacket ranks fifth heaviest jacket in the world and the heaviest in the Asia. Many changes were encountered by fabricator due to its heavy weight and relative short length of the jacket. This paper is to summarize new fabrication methods and techniques developed...

... are measured in microstructures typically present in the intercritically reheated coarse grained HAZ (ICCGHAZ) of a 490 MPa forging. Focused ion beam (FIB) is used to fabricate pillars from weld thermally simulated ICCGHAZ with cooling rate corresponding to a cooling time between 800 and 500°C (Δt8/5) of 5...

... and tested. The results indicate that a liner could be fabricated with superior mechanical properties to enable long lengths of pipeline to be remediated. INTRODUCTION The breadth of the oil and gas industry has necessitated major investments in pipelines for the transportation of its fluid products...

... to be monitored during the fabrication of the product. Given that quality cannot be ‘designed in’ to the finished product in the absence of destructive and non-destructive tests, such tests are required to be carried out on both the finished product and on qualifying test pieces produced before and during...

... beam (FIB) as a machining process to prepare micron-sized specimens. After fabrication the specimens are tested with a nanoindentation device. Experimental results show that quantitative data can be obtained at the micron and submicron length scale, but further development are needed at this early...
