Overview
Objectives: Carrying out the Chikyu's first implementation of riser drilling and complete the five remaining system integration tests in preparation for the launch of the Chikyu's international operations for the Integrated Ocean Drilling Program (IODP).

[System integration tests (SIT)]

  1. Running the riser and blow-out preventer (BOP)
  2. Testing the emergency disconnect sequence (EDS) for the riser and BOP
  3. Inserting the casing pipe and cementing
  4. Test operation of the Chikyu’s three core sampling systems
  5. Testing the wireline logging system (which measures formation properties.)


[Major training evolutions]

  1. Tests of and training in logistics for personnel and supplies by helicopter and supply boat
  2. Examination of the treatment systems for cuttings and waste mud
  3. Testing and optimization of shipboard and land-based safety and security systems
  4. Optimizing procedures for core sample processing and for quality control on core samples
  5. Building onboard procedures such as those for processing wireline logging data.

Science Project
Science objectives
  1. Obtain functionally active microbial cultures, cells or molecular signatures from the cored formations
  2. Distinguish the depth-dependent microbial populations of dead, dormant and living cells
  3. Construct microbial metagenomic libraries from the subseafloor biosphere for the first time
  4. Estimate the resource potential and magnitude of subseafloor methane hydrate deposits
  5. Resolve the mechanisms of generation, transportation and enrichment of methane associated with either lithological and hydrogeologic properties
  6. Retrieve paleoenvironmental records and paleomes (ancient biomolecular assemblages)
