... of the eight OCS platforms being decommissioned, if fully removed, would each establish world water depth records for removing conventional steel platform jackets from the seafloor. The paper also describes the major technical, logistical, environmental, and regulatory challenges operators face in planning...

... Abstract Petrobras has operated offshore production units on the Brazilian coast for over 25 years. Over time, its facilities are expected to degrade due to the variety of mechanisms of damage that the offshore environment provides. Mooring systems are among the assets that present degradation...

... Abstract Offshore pipelay is a complex activity that is subject to some risks due to the challenging operating scenario. The risks may concern the workers during pipes handling, the subsea environment that may be subject to huge seabed rectification works and the integrity of the pipeline...

... (or RDOC) was established after the Macondo incident in the Gulf of Mexico. Its primary focus was managing process safety risk—well control in particular—in deepwater and complex wells as defined by Chevron's global standard operating procedures. The role of the DSC in process safety is primarily...

... robots presenting AUV/ROV hybrid capabilities, enable new attractive operational paradigms that are already being positively recognized by the offshore industry. The use of UIDs, particularly when permanently integrated into fields (topside or as subsea resident) could greatly contribute to reducing...

... 2 is sequestered in a geologic reservoir. However, the CO 2 mixture may move across the phase boundary during transient operating scenarios due to the narrow operating envelope. The presence of impurities significantly increases the risk of multiphase flow with implications on the cost...

... of this is that the extreme wave-driven vessel excursions will be large in comparison with the average motion. A marine operation can only be carried out provided the critical variables of response stay below given limits with a sufficiently large probability. To estimate probabilities of limit non-exceedance, simulation...

... adaptions and prioritization in engineering approaches to address the needs of future scenarios of arctic maritime activities. Several crucial aspects to be considered when investigating the interaction of sea ice with a floating platform or vessel are reviewed and disussed through an exemplary operation...

... Abstract The authors will present examples of how revising base layer control strategies have resulted in improved compressor operation in a mature deep-water asset. The revised control strategies have resulted in improved production and capacity whilst reducing greenhouse gas production...

... monitoring systems. Critical factors for offshore CCS implementation include the identification and development of technologies to reduce operative costs; development of professional skills for field implementation; use of digital technology to improve data processing; improvement of exiting offshore...

... Abstract In 2009, the Vito field was discovered in more than 4,000 ft of water approximately 150 miles offshore from New Orleans, Louisiana. The project produces from reservoirs nearly 30,000 feet below sea level. This paper outlines the approach taken to develop the Vito facilities operating...

This is triggering oil and gas (O&G) attention to find faster and economic ways to decarbonize while maintaining operational performance. Several types of initiatives are being considered including the reduction...

After that a completely new fleet of Double Acting tankers and icebreaking support vessels have successfully proven their abilities. The same development has enabled even larger and more capable ice vessels. Podded propulsion is an attractive...
