Profil de vie Glider Slocum#070 12/11/2008 17:37 Fiche de vie glider potame (Slocum #070) Date 12/01/07 Lieu LPO Brest Objet Shipped by WRC via Nantes 22-23/01/07 LPO, Brest Power on the glider for the first time 28/01/07 LPO, Brest 30/01/07 IMEDEA, Calanova Ship to Mallorca, Imedea for Med deployment Prepare and ballast 31/01/07 IMEDEA, Calanova 01/02/07 Off Soller, Mallorca 02/02/07 04/02/07 18/02/07 02/03/07 Document de référence Observations Airshipped from Boston / Paris / Nantes and then truck Nantes to Brest. Nantes is the closest airport with cargo facilities. Due to the box sizes, it can only go in a cargo. Open the box and visually inspect the glider and the box content. Nothing to note. Compte rendu de préparation et Activate the SIM Iridium card. Change the autoexec déploiement d’un planeur Spray with glider name and phone number to call. Check functions : pump, GPS, Iridium calls. Check et du Slocum profond du LPO dockserver en Méditerranée Occidentale dans le cadre de MERSEA WP3, T.Terre, P.Lherminier, February 2007 idem Door to door shipping by special truck idem Check CTD + oxygen sensor Check ballast for potame idem idem Off Soller, Mallorca First try to pdeploy the glider but cancelled due to bad weather Deploy the glider but unsuccesfull. Decide to get it back to Brest for pressure tank tests. Verification of pool water characterisitics showed a significance diffrence with the previously assumed numbers. Deepy alone was deployed IMEDEA, Calanova LPO, Brest LPO, Brest Prepare for shipping back to Brest Glider back to lab Open and separate the 3 sections idem During the first try of the mission at 30 m, the glider never came back to the surface due to a bad functionning of the vehicle pressure sensor. Vaseline was introduced in the capillar for corrosion problem but it prevents the pressure to be correctly transmitted to the sensor. Back to shore with the glider. idem Door to door truck shipping with the same carrier This is to change the vehicule pressure sensor capillar tube 1/5 Profil de vie Glider Slocum#070 12/11/2008 17:37 05/03/07 LPO, Brest Dismount tube and check the pressure sensor 12/03/07 LPO, Brest 13-16/03/07 LPO, Brest 19-20/03/07 LPO, Brest Replace the capillar tube and check the overall pressure sensor circuit. Close the glider and put a vacuum at 7.4 inHg Check the vacuum is not decreasing . record Vacuum and internal temperature. Open the glider again to prepare the pressure tests by setting a cable for communication thru the pressure tank C. Jones visit to LPO Report on Clayton Jones visit to Pressure tank tests while running the pump Ifremer/LPO, T.Terre, march at 250 db and 1000 db 2007 Pool trials 12-20/04/07 OOB, Banyuls Preparation and deployment with N/O Nereis 17/04-18/06 Western Mediterranean Contribution to the convection monitoring with NOC and LOCEAN teams Compte-rendu de récupération d’un planeur Spray et de préparation et déploiement du Slocum profond du LPO en Méditerranée Occidentale dans le cadre de Mersea WP3, T.Terre, mai 2007 Report on operations with Slocum Potane (unit #70) in Western Mediterranean Sea. T.Terre, July 2007 2/5 Vaseline clearly seen at the entrance of the pressure sensor. Check pressure variation with vacuum pump and nitrogen injection (adtest) Same vacuum pump and nitrogen use Vehicle pressure sensor OK Pump ran OK in presure tank Pool tests showed offset between vehicle pressure sensor and SBE CTD pressure sensor Pump was set OUT OF SERVICE due to an OUT OF DEADBAND error (later corrected by soft) Shipping door to door with Ifremer van Start in mission without DO sensor running. Set up Later by changing sbdlist.dat Diificulties to connect with Iridium : got an abort MS_ABORT_DEVICE_ERROR 2007-0506T18:43:57 18/05 Leak detect Abort; Recovery and check; Loose screws shortening the leak detect sensor ! Redeploy on 19/04 Start in mission without DO sensor running. Set up later by changing sbdlist.dat Difficulties to connect with Iridium : got an abort 06/05 : MS_ABORT_DEVICE_ERROR 2007-0506T18:43:57 20/05 : Deep engine out of service OOD:oil_volume:OUT OF DEADBAND: M_su:225.4825 C_su:266.3760 change f_de_oil_vol_deadz_width from 40 to something bigger 10/06 : abort due to a bad syntwx in a mafile.

Questions raised : Compte rendu de récupération 1. Test of Iridum link d’un planeur Slocum profond du 2. purge of deep engine return to WRC ? LPO en Méditerranée 3. air bladder attitude, does oxygen sensor Occidentale dans le cadre de have an effect ? MERSEA WP3, T.Terre, juin 4. Cycles the pump at 1000 db in pressure tank 2007 to empty the lithium batteries 5. Change pressure hull from aluminium to composite ? Report on Iridium, pump test Run the pump for 140 cycles at 100bar with the and batteries discharge after batteries used during the experiment. Medterranean Sea dployment Discharge the batteries on resistive loads Transport Brest-Mallorc-Brest by Ifremer van, driver TT.
