Passive fire protection (PFP) has been used as a method to avoid/delay global collapse of offshore installations. Location of PFP is often based on simplistic assumptions, standards, guidance, and methods that do not always consider the real response of the structure to fire.

The papers in this month's issue describe an optimization method for long-distance gas-transmission pipelines, a potential solution to handle produced water from subsea wells. the driving forces in paraffin deposition, and a novel method to verify leaks in a sulfur-recovery unit condenser.

Valuation of the enhanced flexibility offered by platform-based development solutions and sequential subsea solution is difficult. This leads to the question: Are development solutions being selected without taking sufficient account of option values?

In this study, software that is capable of modeling fully transient multiphase flow in wellbore and pipeline has been used to characterize the fluid-hammer effects of well shut-in and startup on the coupled subsurface and surface systems.

A closer look at the design and construction of Statoil’s subsea gas compression systems in the Åsgard and Gullfaks fields, the first of their kind in the oil and gas industry.

This paper illustrates a numerical approach to estimate the deposition profile of precipitated wax crystals and its effect on flow-related parameters in pipelines. Options for avoiding these issues are also explored.

There are few deepwater-pipeline operators with expertise in pipeline repairs. This paper describes a strategy developed and implemented on deepwater-pipeline intervention, based on a deepwater operational experience built over a decade.

This month's papers cover development choices for an offshore field, cost-estimating errors when planning compressor stations, and the engineering aspects of smart fields.

As low as reasonably practicable (ALARP) is common for management of safety risks, but harder to apply to environmental risks. This paper explores the differences and proposes a modified method to support environmental risk analysis.

The smart-field concept is deployed through disseminating elements of tools and infrastructure integrated to bring a level of smartness that can improve the performance of an oilfield asset in a sustainable way.  How this is accomplished can vary widely depending on the field.
