Mechanical pressure clamps are examples of innovative tools commonly used in the oil and gas industry for arresting leaks from damaged oil and gas pipelines. However, if leaks result from pipeline rupture, clamps are not usually recommended. It is therefore obvious that inspection of the leaking pipeline is very crucial in deciding the strategy for repair. For subsea pipelines where underwater ...
A subsea pipeline (also known as an offshore or submarine pipeline) is a that laid on the seabed inside specially constructed trench [...]
The development and implementation of new technology within the execution schedule and finance model of a deepwater subsea project requires attention to design detail, and a culture of meticulous qualification and verification practice. Challenges faced by project leadership and project teams occur in the merging of new technology product(s) into the timeline allocated for delivering the more c...
The work develops a redundant software system for subsea blowout preventers, including control logics, human-machine interface (HMI) programs, remote access and redundant databases in order to meet the high reliability requirement of subsea drilling. The Bayesian networks (BN) for control logics, HMI programs and redundant databases are built and then the whole BN are established. The quantitat...
The purpose of this short study was to identify the drivers of export orientation of firms in the subsea oil and gas industry in Western Norway. As the oil fields in the North Sea are approaching a stage of maturity, gaining knowledge of these drivers is crucial. An online survey was conducted of firms operating in the subsea oil and gas industry in the region. Consistent with previous research...
Sustained release of methane (CH(4)) to the atmosphere from thawing Arctic permafrost may be a positive and significant feedback to climate warming. Atmospheric venting of CH(4) from the East Siberian Arctic Shelf (ESAS) was recently reported to be on par with flux from the Arctic tundra; however, the future scale of these releases remains unclear. Here, based on results of our latest observati...
This paper describes the simulation setup applied in an introductory study in connection with implementation of subsea processing equipment at an already operating gas and oil field. The primary aim of the subsea processing equipment is to increase the oil recovery, but it is also considered as an important technological step forward. A subsea separation and boosting station is planned installe...
Submarine cables play a fundamental role in global telecommunications. In recent years, the internet traffic is experiencing a remarkable growth due to the large number of resource hungry applications which often require large traffic between data centers. In parallel with this traffic growth, optical transmission technologies have experienced a remarkable transformation providing large improve...
In this paper is described the system that controls the connected devices in a subsea observatory. The control system is constantly monitoring the internal and external components of the observatory detecting operating faults and acting automatically in consequence.
