Case Study

Winches and A-Frame systems for Indian Oceanographic Research Vessels
Caley Ocean Systems has supplied oceanographic winches and A-Frame systems to Hyundai Heavy Industries (HHI) for the Geological Survey of India’s oceanographic research vessel, Samudra Ratnakar.

The state-of-the-art vessel can survey the full ocean depth (10,000m) using advanced exploration capabilities. Caley has provided bespoke traction winches which can handle high tension and heavy loads. The ‘SMART’ control sysetms enable fully active heavy compensation, and variable frequency drives. Caley has also supplied a Conductivity, Temperature and Depth (CTD) Rosette Handling System.

The systems are designed to be used by a single operator, allowing them to control the deployment and recovery of the CTD system without involving other crew. The CTD Handling System has in-built motion compensation to cancel out the roll and pitch of the ship, significantly reducing the swaying of the CTD system. This enables a smoother and safer deployment and recovery operation.

The vessel features high performance stern and side A-Frame systems for seabed drilling and coring equipment. Caley worked with its long-term Korean agent and sub-contractor on the manufacture of these A-Frame systems.
