Many problems that result in BOP downtime could be prevented if only drilling contractors knew which parts of the subsea system to replace and when. BOP monitoring systems have been developed to increase reliability by enabling preventive maintenance.

During OTC in Houston last month, offshore construction capabilities drew a room-capacity audience to a technical session about advances in deepwater construction techniques and vessels, including pipelaying and heavy lifting.

Deepwater capital expenditure is expected to more than double compared to the previous 5 year period. Douglas-Westwood also expects a continued trend toward exploration in ultradeepwaters in depths greater than 2000 m.

This paper focuses on the applicability of subsea processing technology employing multiphase pumps to develop marginal fields commercially. Analytical methods were used to evaluate the pumps, and the results were validated through case studies in specific fields.

As environments become more challenging, the importance and complexity of flow assurance has evolved. To effectively manage flow assurance, oil and gas operators must take a holistic approach, particularly when working in deepwater offshore environments.

Record-setting megaprojects are driving innovation at the installation and subsea construction firm.

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.

Technology is evolving to meet the challenges to automate water separation and purification in deepwater for environmentally safe discharge at the seabed. To solve these problems the best available solutions must be selected and the technology gaps must be identified and closed.

In 2013, as deepwater projects become increasingly capital intensive, there are economic challenges for exploration and production (E&P) companies and a potential prize for international oilfield service and equipment vendors. Deepwater represents a long-term opportunity.

Industry has overcome the technical challenges with decommissioning in shallow water. But as deepwater structures require removal, a whole new set of decommissioning challenges will require new solutions. This article highlights some of these challenges.
