Research Vessels and Moored Platforms in India

Presentation : Arjun K sabu What is a research vessel in oceanography ?

Research vessels carry out research on the physical, chemical, and biological characteristics of water, the atmosphere, and climate, and to these ends carry equipment for collecting water samples from a range of depths, including the deep seas, as well as equipment for the hydrographic sounding of the seabed, along with numerous other environmental sensors. These vessels often also carry scientific divers and unmanned underwater vehicles. Types of Vessels

 Hydrographic Vessels  Oceanographic Research Vessels (ORV)  Polar Research Vessels (PRV)  Fishery Research Vessels (FORV)  Navel/Defense Research Vessels  Coastal Research Vessels (CRV) Research vessels in India RV Gaveshani ( 1975 - 1995 ) Gaveshani (meaning: Researcher), was NIO's first research vessel acquired in December 1975. In her 19 years of service (until 1994), she completed 246 cruises. She accidentally caught fire on 26 August 1994 during refit and modernisation. She was then declared unserviceable in December, 1995.

Moorings are structures that allow water scientists to position instruments, collect samples, and take long-term measurements in waterbodies. A mooring typically consists of a flexible cable that is tethered to the ocean floor by a weight or anchor and suspended from the sea surface by a buoy. A platform has a flat workspace for instruments and people, and can be free-floating, moored to the seafloor, or rigidly fixed in place.

Water scientists, including physical and chemical oceanographers, marine biologists and geologists, meteorologists , and lake scientists called limnologists collect many types of data from instruments installed on moorings

Single Point Mooring (SPM)

Single point mooring (SPM) serves as a link between the shore-facilities and the tankers for loading or off-loading liquid and gas cargo

Some of the major benefits of using SPM are:

 Ability to handle extra large vessels  Doesn’t require ships to come to the port and thus save fuel and time Ships with high drafts can be moored easily Large quality of cargo can be easily handled Some SPM’S in India:

Borl SPM1 Essar SPM1 HPCL - MITTAL SPM IOCL PARADIP SPM II IOCL PARADIP SPM III Reliance SPM 3 Reliance SPM 4 Reliance SPM 5

Moorings deployed by INCOIS(Indian National Centre for Ocean Information Services) Surface Mooring

Implementation of moored-buoy array for the Indian Ocean in support of climate studies. The focus is on the open ocean north of 30° S. Special efforts will be needed to address western and eastern boundary currents, the Indonesian Throughflow and coastal dynamics.

The array will focus on those aspects of ocean dynamics, ocean- atmosphere interaction and climate variation that require high temporal resolution, multi-variate time-series, which moored measurements are uniquely suited to address

The array will be long-term and sustained

Real-time data transmission will be a high priority in order to support operational climate analyses and forecasts

Data will be freely and openly exchanged via the GTS and the WWW The flux reference moorings located in several key climatologically distinct regions, including:

 Bay of Bengal .  Arabian Sea  Equator  Region of subduction in the southeastern basin (see the CEC in section 6) (25°S, 97°E)  The ridge in the thermocline near 8°S, where ocean dynamics affect SST  Region of cyclone formation east of Madagascar Region of maximum rainfall south of the equator near 95°E.
