Panel 3-3 : Underwater intervention and 20years plus material choice Chairs : Jean-François Drogou (Ifremer), Volker Ratmeyer (Marum) Dominique Choqueuse (Ifremer) and Marck Smit (NIOZ) Thursday 8th - Underwater intervention They are no standards or recommended practises covering globally the subject of ROV intervention, apart form the NORSOK "U-102 Remotely Operated Vehicles (ROV) services". Most of the know how is retained by each individual operator, and is hardly exchanged within the industry, for obvious reasons of commercial competition. However, it would be advisable for the scientific community for which commercial competition is a far less present parameter, to build up a database related to ROV intervention, collecting data on vehicles performances, tooling and sensors usage feed-back, break down statistics, operational hazards, crew manning, maintenance tricks, etc. , which could lately be the base for a general recommended practise on underwater diverless intervention. The work should also cover ultimately the AUV operations, for which the underwater community in general, still misses a real feed-back. The existing intervention equipment (Submarines, ROV and AUV, hybrid vehicles ) available within the scientific community will govern the early days of intervention procedures on underwater observatories (methodology and operational procedures are largely dependant on the intervention equipment specifications), it will be beneficial in the long term to work out the specifications of standard vehicles, which will offer both performances and versatility, and would allow the various laboratories to exchange hardware, operators and know how. Objectives: The objective of the working group would be to provide the scientific users with proper guidelines on what equipment to use for each type of missions, and recommended practices to operate it in a safe and productive way. As a case study, it would be interesting to compare how an observatory deployed during a demonstration mission (LOOME, MomarD, Lido, MODOO...?) would be deployed using existing ROVs. At least two cases are to consider. Friday 9th - 20 years + lifetime material choice In the definition of subsea observatories, from the scientific vision to the cost estimates, the long term durable operation is a key issue and probably a limitation. Any improvement in the limitation of ageing of materials and components is worth being analysed. The choice of material and its protection towards corrosion has not yet been addressed directly inside Esonet. The panel will start from a white paper issued before the Workshop (from Esonet CA Final report). It will work with the practices of the oceanography partners but also from offshore oil and gas industry and Navy experience. Topics intended: 1. corrosion protection of steel - cathodic protection, 2. choices of materials and strength after ageing corrosion due to neighbouring materials (components such as connectors, actuators, cables), 3. thermoplastics and composites - ageing issues. ESONET partners already designed equipment for the Demonstration Missions. One or two of these equipments could be used as a case study for analysis of the material choice, other possible choices and other practices. <strong>Deliverable</strong> #50 - update October 2010 52
Objectives: The first meeting of this panel intends to establish an initial reference paper. Whenever possible, the group will recommend rules or standards, check lists and material ageing test methods. It will determine the additional work or experiments ESONET could support. A question: Can all the ESONET-EMSO equipments (infrastructure and instruments) have a life time of 20 to 30 years with state of the art material design? What attendance/ checking /maintenance will be needed? <strong>Deliverable</strong> #50 - update October 2010 53
