The selection criteria for multiphase boosting options remain somewhat subjective and are frequently influenced by the vendors’ data, which may mask potential limitations of this emerging technology. Existing literature on multiphase pumping tends to focus on a certain pump type for a specific field application, but does not provide more-generalized criteria for the selection of multiphase boos...

Subsea pipelines buried in the seabed may undergo large lateral displacement under environmental, operational, and accidental loads at different interaction rates hence drainage conditions. The undrained shear strength is commonly used practice to assess pipe-soil assuming a sufficiently high rate. This approach neglects consolidation effects rate-dependent response of soil significantly undere...

Taking a subsea collet connector as an example, the contact characteristics of sealing structure under thermal–structural coupling were studied. Considering heat transfer problem in deep water, model seawater layer between structures was established, and relationship equivalent thermal conductivity, composite coefficient, temperature determined. The steady-state field distribution action intern...

The teleprogramming paradigm has been proposed as a means to efficiently perform teleoperation in the subsea environment via an acoustical link. In such a system the effects of both limited bandwidth channels and delayed communications are overcome by transmitting not Cartesian or joint level information but rather symbolic, error-tolerant, program instructions to the remote site. The operator ...

As the time between initial concept and commissioning of submarine cable systems decreases, the need for automated tools and procedures to facilitate the acceleration of the route and cable engineering processes increases. Cable installers are now faced with more projects and less time to design, engineer, and install these systems. These increased demands mean that, in many cases, traditional ...

A simple underwater noise model suitable for use with explosives in the decommissioning of oil and gas subsea structures is introduced evaluated against data from five projects US. The performance compared to four existing models open water blasts, severance well conductors piles. Simulated received sound pressure levels were significantly correlated measurements all scenarios. maximum total er...
