We are delighted to announce the final of our three instructional webinars relating to design of subsea pipelines. Here we look at end expansion. The considerations for designing pipelines to accommodate expansions arising from combined thermal, pressure and Poisson’s ratio effects are introduced. Learning outcomes include: Understand stress behaviour of axially restrained and unrestrained pipelines …
Our second of three, free training Design webinars explores the materials specification that need to be factored into any design of pipeline. During this webinar, your host Dem Demetriou, will look at the material selection, the properties associated with those materials and the line pipe technical standards. By the end of this webinar: You will …
Ageing subsea infrastructure in the oil and gas industry is a concern around the world. Operators must demonstrate that they are not exposing society to a greater risk through continued operation as pipeline systems that convey their products are operating close to or even past their design lives. An extension to the operating life of …
Before committing to a pipeline design, the route along the seabed it will take has to be considered. During this webinar, the first of three dealing with topics relating to Design, your host Dem Demetriou, will detail the different areas that are studied even before a design can be put to paper. Learning outcomes; – …
Extending the operating life of flexible pipelines Unbonded flexible pipe was primarily developed for use in dynamic systems where the use of fixed rigid solutions was impractical, such as in deep water. Following a number of early failures, improvements to the unbonded flexible pipe design and manufacturing process have resulted in increased reliability and therefore …
Managing with less: Lower your risk profile in the low economic environment The past two years have seen the oil price plummet to record lows and eventually slowly start to increase. As a result, there has been significant pressures within the industry to cut costs from every budget. Activities have been deferred into future years, …
Over the long history of the North Sea many assets have changed ownership and/or operatorship. This brings with it a host of challenges, from effective continuity of data management, different approaches to integrity management and potentially interrupted operation. Pipelines that were designed for one application may now be required to adapt to a new operation …

Avoiding down time due to repairs With the power generation capacity of offshore wind farms increasing exponentially over the past 20 years, subsea power cables have also increased in number to accommodate the transmission of this increasing supply. These cables are being installed in ever increasingly harsh environments and are susceptible to failure when their …

Subsea cables are the Achilles heel of the offshore renewables industry. They are often not given enough consideration during the project design stage and as a result they can present problems during operation that are costly to rectify. Such problems may include fatigue and over-bending from scenarios such as spanning from a bell-mouth, cable exposure …

Challenging the base case Overview The growing decommissioning activity in the North Sea is forecast to cost £47 billion. With the government’s drive to reduce this cost by 40%, the industry and supply chain must make significant cost savings during decommissioning. In order to achieve these reductions in cost safely, there is an inherent need …
