Metocean data for design: why models and measurements are not an alternative but a complement – click here for presentation
Ambre Tréhin, Fugro
In-situ metocean measurements provide real data on local conditions; numerical models provide data for long time periods. We will be looking at why they should not be seen as alternatives but rather as complementary sources, which when used together produce the highest quality design criteria.

Structural Monitoring: Instrumentation, Analysis and Industry Challenges – click here for presentation
Stuart Killbourn, Fugro
A whistle stop tour of structural monitoring for subsea wellheads, risers and platforms across six continents. We will see instrumentation systems deliver performance data to inform operational decisions in a timely manner.

Timings: 5.30pm for 6pm presentation followed by cheese and wine
Cost: Members £15 (inc. VAT) Non-members £25 (inc. VAT) Students £5 (inc. VAT)

Presentation:

Two major projects have recently been completed using ROVs to perform friction welds on wind farm piles and a Floating Production System with newly developed equipment.  This process has also been used with ROVs for welding to subsea pipelines and production assets and with divers for structural repairs and retrofitting Cathodic Protection.   The presentation will give a brief overview of the system and cover recent case studies.    Friction welding is a solid phase welding process that can be used in deep water and produces welds of excellent fatigue strength.  Other methods of welding underwater including wet welding and dry habitat welding will be reviewed during the introduction.

Speakers:

Dave Gibson, Technical Authority Friction Welding, Proserv

Stuart Harvey, Product Champion for Friction Welding, Proserv

Methane hydrate deposits are known to exist in both onshore permafrost regions and subsea in water depths exceeding 500 metres. However, there is still considerable uncertainty over both the locations of these deposits and the volume of methane that may be trapped.  The total amounts of trapped methane are still unclear but current estimates are well in excess of all known conventional fossil fuels discovered to date.

Pilot production wells have been drilled and tested onshore in Alaska and Siberia. Then, in 2013, the first pilot production well was drilled and tested offshore Japan. However, no commercial exploitation is currently planned.  One option under consideration is to inject CO₂ into hydrate accumulations and displace the methane, both leaving the CO₂ in place and reducing the risks posed by dissociation.

Two teams of Cranfield University students were presented with the challenge of identifying technically feasible development options for offshore hydrate deposits and recommending options for future commercial consideration.  Both mature and frontier locations were to be used as case studies to highlight any major differences.  This was set as a Group Project that forms part of the M.Sc. in Offshore and Ocean Technology with Subsea Engineering and has been run as a design competition between the two teams.

Each team was set the following scope of work:

• Identify the potential volume of methane in hydrates worldwide and the known locations of significant subsea deposits


• Select one mature and one frontier location for use as case studies


• Identify possible production technologies and key technical challenges


• Create a set of development options


• Assess each option based on strengths, weaknesses, opportunities and threats


• Recommend and select one option for each location for further consideration


• Define these options in more detail
