  1. MIRAI CRUISEAugust 11 to September 21, 2011 I. INTRODUCTION Mirai Cruise a part of Research Agreement between Japan Agency for Marine-Earth Science and Technology (JAMSTEC) with Agency for the Assessment and Application of Technology on the “Climate Variability Study and Societal Application through Indonesia-Japan “Maritime Continent COE”- Radar –Buoy Network Optomization for Rainfall Prediction” which is operated under the Science and Technology Research Partnership for Sustainable Development (SATREPS), for the capacity building program of buoy Maitenance to be held on board of JAMSTEC R/V Mirai. We will doing observation, Lecture and On Job Training during on board R/V Mirai.

  2. August 10, 2011 Departure from Jakarta, 11.15 PM August 11, 2011 Arrive in Narita Airport , 09.00 AM August 11, 2011 Arrive at Mutsu, 05.00 PM August 12, 2011 - Visit to JAMSTEC facillity August 13,2011 - On Board R/V Mirai - Departure from Sekinehama August 14, 2011 - Arrive at Hachinohe - Clearance Out in Imigration

  3. II. VISIT TO JAMSTEC FACILITY IN MUTSU

  4. III. TRAINING ON RV MIRAI Schedulle training on R/V Mirai for BPPT DRILL DRILL SIMULATION RECOVERY AND DEPLOYMENT TRITON BUOY Simulation Recovery and deployment Triton Buoy Briefing schedulle MR-11 cruise

  5. Pick up III.1.On Deck maintenance of Surface Buoy Current Hovering （buoy maintenance ） and Re-deploy Wire wind up Depth 2870ｍ Remains of wire 3330ｍ Buoy towing Vessel Wire Length 3840ｍ anchor K-TRITON Repair K-TRITON without Release Anchor

  6. III.2. Preparing Mooring Triton Buoy Its must doing before deployment operation for Certainly all equipments to be used working well. • There are 6 locations Triton buoys deployed during the cruise mirai: • Triton 10 at 7d52N, 136d29E depth 3350 m • Triton 11 at 4d51N, 137d16E depth 4110 m • Triton 12 at 2N, 138E depth 4320 m • Triton 13 at 0d 04N, 138d02E depth m • Triton 16 at 1d 57N, 130d 11E depth 5310 m • Triton 14 at 7d 58N, 130d 02E depth 5725 m

  7. III.3. Deployment Triton Buoy Deploy sinker Deploy (floatter) • Deployment Procedure : • Deploy 50 m length wire with installed 3 sensors • Deploy triton buoy at sea surface • Attaching underwater sensor to wire • Install the lower electrode to wire end connector • Deploy nylon rope • Attaching buoy (floatter) 3 buoys and 2 buoys • Deploy nylon rope • Install acoustic release with chain • Deploy 50 m nylon rope • Deploy anchor • Ship speed 1 – 2 knot • Distance sinker posisi target with launch sinker, 40% from deapth sea Deploy wire and sensor Attach underwater sensor Install the lower electrode to wire end connector

  8. III.4. Recovery Triton Buoy • Recovery Triton 10, depth 3350 m • Recovery Triton 11, depth 4110 m • Recovery Triton 12, depth 4320 m • Recovery Triton 16, depth 5310 m • Recovery Triton 14, depth 5725 m • GENERAL PROCEDURE : • Get on primary rope (50m length) to buoy by rubberboat • Send enable command to lower A/R • Connect ship to primary rope by rubberboat • Triton buoy on deck • Recovery the wire rope • Remove underwater sensor from wire • Recover nylon and polypropylene ropes • Recover buoys (floatter) • Acoustic release on deck • Ship speed 1 – 2 knot.

  9. III.5. Maintenance and cleaning sensors Maintenance for the all sensors must be doing After recovery. • Cleaning of underwater sensors • Cleaning Meteorological • sensors • Setting Parameter CTD Sensors • Recharge Battery CT sensors

  10. IV. OTHER ACTIVITY • Monitoring navigation on bridge • CTD • Monitoring Data CTD on bridge • Deployment ADCP Mooring • Turbomap (MSP) • Test data meteorological sensors

  11. Summary • Capacity Building and Transfer Technology was done on R/V Mirai, MR 11-06 Cruise from Sekinehama to Singapore on 13 Augt to Sept 20, 2011 • Buoy installation, Operation, Deployment and Recovery was implemented • Countermeasure Technology against Vandalism has been developed and tested • Observation parameters and buoy sensors configuration was optimized (pre, processing, and post) • Safety First is considered highly during operation
