A summary of the responses to a questionnaire introduced in the February issue of Oil and Gas Facilities sheds light on the experiences of respondents and their observations of the drivers of project complexity. There is often a discrepancy between the theoretical means for process improvement and the results of their real world applications and execution.
A DNV GL joint industry project brought together operators, contractors, and manufacturers to develop a recommended practice (RP) for carbon and low alloy steel forgings for subsea applications. The RP aims to build consensus in the specifications for melting practices, forging, heat treatment, testing, and further processing to reduce delivery lead times and improve quality and reliability.
New technologies, practices, computer modeling, and design may help to improve the methods for the condition assessment and management of life cycle for risers. An area of recent study has addressed methods to improve the prediction of the riser annulus environment.
The low price of oil has resulted in operators’ announcements of required reductions of 20% to 50% from current levels of project costs for projects going forward to be considered affordable. This level of capital cost reduction is not going to be achieved by “nibbling at the edges.” Cost reductions of this magnitude require a serious rethinking of the strategy for developing and executing projects.

The types of hydrocyclones used in the North Sea and the deepwater US Gulf of Mexico are compared. The reasons for the different types of installations are described.
A study examined the precipitation of calcium, magnesium, barium, and strontium by the addition of target ligands, followed by solid separation with electrocoagulation.
A model-simulation method may be applied when either the rates or the pressures at the inlet and outlet of a pipeline are unknown. The method provides an approach to locate and estimate leaks in both a single pipeline and parallel pipeline.
The weight of a planned offshore facility drives the cost, schedule, and complexity of the project. A review of more than 150 offshore projects around the world shows that weight growth is much higher than expected and the causes are discussed.
