... Abstract This study investigates the effect of seismic loading on the performance of a shared suction caisson anchor for a floating offshore wind turbine (FOWT) array with taut mooring configuration in anormally consolidated clay deposit. A three-dimensional (3D) finite element (FE) analysis...

... pipes with two CO2 offloading systems—Single Anchor Loading (SAL) and Submerged Turret Loading (STL)—known for their endurance, flexibility, and uptime, enabling continuous CO2 injection in all weather conditions. The corrosion-resistant flexible pipe, in combination with the CO2 offloading systems...

... Abstract We performed uniaxial compression tests on specimens from a sandy silt reservoir with a hydrate saturation greater than 80% and on specimens of the same reservoir without hydrate present. During loading, the hydrate-bearing reservoir samples are stiffer than equivalent samples without...

... and loading history under displacement-controlled deformation. New and existing copper fatigue test data are used to establish a mean-stress sensitive fatigue damage model. This is used to estimate the added damage from the relaxation phase, and allows us to compare displacement- and load-controlled tests...

... loading. One of the most critical loading conditions is cyclic tensile loading acting simultaneously with a net tensile load, which may cause large accumulated tensile displacement. However, tensile behaviour of suction anchors in sand is not well understood. This paper presents a review of research...

... wells situated in the Jubilee Field, off the coast of Ghana. The sensitivity of dynamic underbalance generation and perforation cleanout performance to changes in readily modifiable gun system characteristics was studied. This includes charge loading, string positioning and management of gun free volume...

..., off-the-shelf components. Prototype systems were tested in a full-scale test designed to simulate the loading conditions during a monopile installation. This test involved installing the prototype sensor protection systems on a sheet pile and driving the sheet pile into the soil. The sheet pile...

... The objective of the centrifuge model tests is to comprehend the failure modes of an SCF as part of a BT, to assess its load-bearing capacities, to compare numerical and experimental results, and to provide insights to improve SCF design procedures. The CX-15 BT is considered the prototype...

... The variation in maximum instantaneous water level is an inherent randomness and is therefore aleatoric, or Type I, uncertainty. The crest elevation was considered the primary source of uncertainty in the jacket loading. A methodology was developed to convert the maximum instantaneous water...

The establishment of new operational limits was based on a meticulous study of loadings, considering their frequencies of occurrence and magnitudes. Additionally, a comprehensive evaluation of the casing and packoff strengths was conducted...

... Abstract Shock loading and damage to drill bit cutters caused by changes in rock formations has long been a challenge, especially for shoulder cutters that are subjected to the highest cutting forces. To overcome this problem, a breakthrough solution is emerging—the "Adaptive" polycrystalline...
