... ABSTRACT Due to the complex marine environment loads, large horizontal deflection of marine risers, and contact and collision between risers and internal pipe strings will occur during drilling string installation and drilling process, resulting in drilling string wear and deformation, which...

... The embedment of the offshore exposed pipelines after installation has a significant influence on its subsequent responses. In this study, the cyclic laying effects on the pipe embedment both in sand and clay were investigated by model tests. It is found that the cyclic loads cause the further significant...

...-induced vibration (VIV) fatigue damage during the wet parking phase of SLWRs is analyzed in this paper, which is found to be significant and could exceed the installation fatigue budget. SLWR pre-laid route is also discussed in this paper taken project examples. INTRODUCTION Steel catenary risers...

The literature showed that several factors can alter the monopile response under lateral loading: soil density (Bayton and Black, 2016), the method of monopile installation (Staubach et al., 2020), geometric properties...

... ABSTRACT Direct electrical heating is a flow assurance method for subsea flowlines. This article considers direct electrically heated flowlines that were installed at an offshore facility in 2004. In 2022, one of the piggyback cables was successfully repaired. The root cause for failure was dielectric...

... ABSTRACT Lateral buckling design for flowlines in deep and ultra-deep water often relies on the use of sleepers or distributed buoyancy modules as buckle initiators. However, these methods can be associated with complex engineering, manufacturing or installation and may not be cost-effective...
