Western Link Cable Laying Ops Move Forward

Cable laying vessel Giulio Verne and support vessel Go Pegasus are continuing with installation and survey work in the Irish Sea along the Western HVDC Link cable route, AWJ Marine informs.

The Western Link Project consists of installing two 600 kV DC submarine cables in the Irish Sea from Ardneil (Scotland) to Wirral (England) for a total route length of about 387 km.

The first campaign of about 117km has been now completed, together with the second campaign and the third campaign.

The first campaign 

The 28km of cable that has been in wet storage to the south of the Isle of Man since December 2015 has now been recovered, joined to the existing cable, and then laid and buried on the seabed.

The cable lay vessel Giulio Verne and the support vessel Go Pegasus are planned to conduct post survey on the third campaign. Operations are expected to be completed by the end of August
2016.

The fourth campaign

Starting in the second half of September 2016, the vessels Giulio Verne and Go Pegasus are due to be carrying out fourth campaign of the cable installation, which will run parallel to the recently completed third campaign. This work will start between the Isle of Man and Northern Ireland and will terminate in the mouth of the Clyde.

For the fourth Campaign (C6), the Western Link HVDC cable will be installed by using a laying and burial “in tandem” technique, in which the vessel Giulio Verne will surface lay the cable on the seabed, while a plough towed by its support vessel Go Pegasus will bury them at a short distance behind.

UTC 2017

The subsea industry has, as all other parts of the oil & gas industry, been seriously rattled by the most severe downturn in the hydrocarbon energy era. However, the realization of what hit us and actions to be taken to sustain a healthy and profitable future is still on-going – unfortunately with thousands of colleagues paying the price by losing their job as one of the most severe consequences. At this time, there are signs that we have reached bottom in terms of most industry indicators, but few experts expect a sharp recovery. Many seem to believe that a slow recovery is what the industry needs in order to avoid an unsustainable capacity build-up, as seen in the period after the financial crisis. Considering the uncertainty of what the future will bring, this year’s UTC Program Committee have decided to challenge all of us to present ideas, experiences, technological innovations, business models and execution models for how to shape our subsea future and explain how and why subsea is the future.
UTC welcomes abstracts based on the topics listed below. If selected, please consider writing a paper in addition to the UTC presentation. From 2017, UTC papers will be published in an international database.
