This article presents the horizontal directional drilling (HDD) as one of most suitable technique used to reduce impact on environment during submarine pipe and cable installation process, especially in coastal area shallow waters. HDD is a drill subsea tunnel or under other designated with goal pull facility through drilled underground tunnel. With development offshore natural gas wind industr...

The use of commercially available autonomous underwater vehicles (AUVs) has increased during the last fifteen years. While they are mainly used for routine survey missions, there is a set of applications that nowadays can be only addressed by manned submersibles or work-class remotely operated vehicles (ROVs) equipped with teleoperated arms: the intervention applications. To allow these heavy v...

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...

Due to the pipelay vessel motions during installation of a subsea pipeline, as-laid direction pipeline changes along nominally straight section route. In High Pressure Temperature (HPHT) presence rogue lateral Out Straightness (OoS) can adversely influence reliability buckle initiation at engineered buckling sites e.g. sleepers. This implies requirement study ensure unwanted buckles are not for...

Durability problem of reinforced concrete for underground structures is a hot issue in the field of structural engineering. For underground structures, the prediction of structural service life and methodology for durability design are needed to estimate structural durability. Taking the case of Xiamen Xiang’an subsea tunnel as background, which is designed to meet the requirement of 100-year s...
