A prototype for the bottom assembly of workover system is manufactured. The test to verify the function of emergency disconnection...

... analysis to reflect the deformation of the seabed, an Euler grid without material properties is set up in the space above the soil layer with a thickness of 3,000 mm, and the subsea pipelines are reserved in the seabed soil with a depth of 900 mm for subsequent assembly. The details are shown in Fig. 2...

... ABSTRACT The load-bearing behaviour of lockbolt systems is for many load cases comparable to that of bolting assemblies, resulting in adopted and modified design rules. Due to a lack of experimental data on the load-bearing behaviour under combined tension and shear loading, a conservative...

... vessel is proposed. Three parts of the deepwater medium workover system: bottom assembly, workover riser, and lifting frame are introduced in detail in this paper. A global dynamic analysis model for deepwater workover riser system is established, and the global strength response results of workover...

... ABSTRACT The current research work investigates by numerical simulations the degradation of aluminium-stainless steel bolted assemblies. Two assemblies settings were used in this study: aluminium-aluminium (Al-Al) and aluminium-stainless steel (Al-SS) lap shear joints with stainless steel...

... ABSTRACT Due to their corrosion resistance, bolting assemblies manufactured from stainless steel are becoming more and more important in various applications, such as in offshore structures and machinery. An enhanced level of knowledge based on publications of the last few years offers...

Efforts made in improving the design and testing of the suction plug-port assembly, and overcoming the challenges during subsea handling are shared in this paper. The purpose of this paper is to raise awareness of several important consideration for better design...

..., preload behavior and slip factor were examined under water using special testing equipment. It was found that lubrication of high-strength steel bolt assemblies according the standards applied does not seem suitable for underwater use. Design surface class of specially coated faying surfaces was verified...

... ABSTRACT According to Eurocode 3, preloaded bolting assemblies made of stainless steel are currently not permitted in steel structures due to the lack of knowledge about the reliability of preloaded bolted connections made of stainless steel. In principal, stainless steel shows tendencies...
