There is growing interest in ‘cold based' operations which dispense completely with the gases, ignition sources, flames and hot work associated with welding for piping repair construction, modification and tie-in work, especially on ageing offshore infrastructure…
Saipem's new pipelay giant Castorone, currently under construction at Keppel shipyard in Singapore, will replace the veteran Castoro Sei as the contractor's flagship vessel for laying large diameter pipelines and serving the growing deep- and ultra-deepwater markets…
Whether it's providing protection for kit in HP/HT environments, keeping corrosion at bay or defending vessels against fouling or iceberg damage, the offshore industry sure does ask a lot of its paint jobs nowadays.Jennifer Pallanich talks to…
Subsea hot tapping specialist TD Williamson has been called upon lately to assist with a number of Southeast Asian gas line tie-ins without recourse to costly and disruptive production shutdowns. TDW's Bancha Pitayagulsarn and Ray Foster discuss the planning and successful execution of these jobs…
A new thinner-walled pipeline concept developed by DNV is claimed capable of significantly reducing the cost of a deep- and ultra-deepwater gas pipeline while still complying with the strictest safety and integrity regime. Meg Chesshyre reports…
Mooring Systems’ 150t spooler for the BP Valhall flowline.Aberdeen-based Moorings Systems has completed the installation of a flexible export flowline to transfer water to a DP tanker at the BP Valhall platform complex in the Norwegian North Sea…
The UC-Berkeley, California spin-out 4D Imaging has unveiled a pipeline integrity monitoring system based on magnetic-resonance imaging (MRI). The system transmits the status of a pipeline to the internet and gives pipeline operators a real-time picture of the health of the pipeline…
Serimax recently fabricated, field joint coated and hydrotested an 85m pipe-in-pipe I-spool on behalf of Technip for Dong Energy’s Oselvar field in the Norwegian North Sea. The I-spool comprises a 10in Super Duplex pipe, insulated along its length…
Since it began addressing safety critical fire water deluge system integrity issues a year ago, Paradigm Flow Solutions has rapidly expanded its provision in this area. The company is now working on life-of-field solutions with two North Sea operators…
Harnessing and transporting multiphase products from often high temperature/high pressure well environments to the processing plant presents many a technological challenge. Tata Steel’s Derek Bish discusses one of them: how to construct and efficiently insulate pipe-in-pipe bends…
Design by analysis rather than the traditional formula approach is the way forward for pipeline operators and contractors looking to cut project costs and timescales, argues TRaC Global consultant Dr Peter Moir.Analysis to validate the design…
Measuring mooring tensionSeattle-based Measurement Technology NW announced successful implementation of its running line tensiometer (RLT) technology with a Samson synthetic rope in a Gulf of Mexico offshore mooring monitoring project engineered by Delmar Systems late August…
Gas is due to start flowing through Nord Stream this month following completion of preparatory works on the first of the twin 1224km-long gas pipelines running through the Baltic Sea between Russia and Germany. Formal inauguration of line one…
Marin Subsea was called out recently for an operation central to allowing Iraq – the world's fifth largest holder of crude oil reserves – to properly exploit its estimated 143 billion barrels. David Morgan looks at how the job was planned and painstakingly executed…
Technological barriers and operator requirements can limit the possibilities available to offshore design teams when it comes to engineering a production riser plan for a deepwater facility. Hybrid solutions and composites will offer some relief…
