overview
KAIMEI is a cutting-edge research vessel that can effectively conduct wide-area surveys of the seafloor, such as the distribution of seafloor resources, and can also conduct comprehensive scientific surveys to understand the formation environment of minerals and mineral deposits.
Equipped with cutting-edge research equipment, it has an offshore laboratory function that can analyze collected samples in a fresh state, and also functions as a general-purpose research vessel, contributing to research on climate change and research on disaster prevention and mitigation against earthquakes and tsunamis.
mission
1. Wide-area surveys of seafloor resource distribution and comprehensive scientific surveys to understand the formation environments of minerals and mineral deposits
2. Understanding changes in the atmosphere and ocean environment related to global climate change and elucidating paleoenvironmental changes
3. Exploration of sub-ocean crustal structure, research into disaster prevention and mitigation against earthquakes and tsunamis

Features
Three-mode seismic exploration system
Crustal structure exploration, which visualizes the structure beneath the seafloor, will be conducted in 3D for the first time in addition to conventional 2D exploration. Choose from the following three modes depending on your purpose.
(1) 3D exploration
[Streamer cable 3,000m x 4]
• 3D imaging of the crustal structure of earthquake zones
• 3D geological imaging of promising seafloor resource areas
(2) 3D high-resolution exploration
[Streamer cable 300m x 20]
• Understanding earthquake faults and geological structures in coastal areas
• Understanding landslide topography and earthquake history caused by earthquakes
• Understanding the distribution of rare earth mud, seafloor hydrothermal deposits, etc.
(3) 2D exploration
[Streamer cable 12,000m x 1]
• Clarifying earthquake occurrence mechanisms and understanding geological structures
• Understanding the geological structure up to the drilling depth necessary to formulate a drilling plan for the deep-sea drilling vessel "CHIKYU"
• Understanding the deep structure of promising areas for seabed resources
Seafloor resource sampling device
The following samplers will be used to collect samples of marine resources necessary to understand the formation environments of rare metals, such as hydrothermal deposits found in the Okinawa and Izu-Ogasawara waters, and cobalt-rich crusts found on seamounts scattered throughout the Northwest Pacific Ocean.
(1) Bottom-mounted system (BMS)
Depth: up to 3,000m
Coring length: 30m (core diameter φ60mm)
(2) Power Glove
Depth of use: 6,000m
Collection capacity: 1m Available in two types: 3-
shell type and 6-jaw type
40m piston corer
12,000m high strength fiber rope
pipe length 40m & large diameter corer (core diameter 110mmφ)
• Extraction of methane hydrate and rare earth mud
• High-precision paleoenvironment reconstruction in previously inaccessible ultra-deep ocean areas
• Clarification of long-term earthquake history in seismogenic zones
CTD/Water sampling device
12,000m high strength fiber rope
CTD/water sampling device (12L x 36 pieces)
• Environmental impact assessment for seabed resources
• Understanding changes in the marine environment related to climate change
3,000m-class unmanned exploration vehicle (ROV)
A 3,000m-class ROV will be permanently equipped, which will be useful for observing the seabed and collecting samples of living organisms and mineral resources.
