ODIM Brooke Ocean can supply CTD Handling Systems in a variety of configurations. These are available as complete turn-key systems or as individual components requested specifically by the client. Each system can be tailored specifically to the client's application, customizable in a number of areas including sheave style, winch size and lifting device configuration.

This photo shows a small CTD handling system designed to be mounted on a small research boat. It incorporates an electric winch, metering sheave and manually operated J-frame for overboarding. All components are mounted on a small skid which can be easily installed and removed.

Safety is always a design consideration in ODIM Brooke Ocean's products. CTD handling systems for larger payloads incorporate a load-latching system that positively locks the CTD package to the end of the lifting device, removing the load from the lifting wire. This is not only a much safer method of handling the hardware, but it also removes an element of complexity from the procedure, eliminating the requirement for the operator to simultaneously operate the winch and lifting device controls.

Cable metering capabilities are built into the system with ODIM Brooke Ocean's proven metering sheave technology. The metering sheaves also come in a variety of sizes and configurations.

For systems which are to be used from vessels of opportunity, packages can be skid-mounted at the client's request with either ISO container corner castings or bolt-on weld plates for traditional deck mounting.

A variety of slip ring winches are also available with electric or electro-hydraulic drives. Winches are available with options such as a level wind and Lebus shell.

System Component Options:

Metering Sheave - Designed and manufactured by ODIM Brooke Ocean, these sheaves come standard with Cable Out and Cable Speed readings and are available in a range of sizes. The sheaves can be configured with additional cable metering capabilities, such as Cable Tension (using a load cell), on request. See the Metering Sheave product page or contact ODIM Brooke Ocean to find out more detail.

Sea-Bird Software - For added functionality, the sheave software can run inside Sea-Bird's Seasave software package. It can also run in Windows. Visit the Sheave Software page for more information on this application.

Lifting Device - The lifting device performs the task of moving the instrument from the deck to the water. Options for this include A-frames, J-frames, articulated cranes, davits and telescoping booms. These can be custom-designed to each application.

Slip Ring Winch - Available in various sizes of electric and hydraulic configuration, the winch can be configured to the client's requirements.

Load Latch - An important and convenient feature of the CTD handling system, the load latch removes the load from the cable as the instrument package is transported to and from the air/sea interface, providing extra stability and safety. The latch is spring loaded so it automatically latches to either the cable termination or a fitting added to the package. A limit switch can be interlocked to the winch to prevent overhoisting.

If there is a requirement to control the pendulum motion of the rosette/payload, a capture saddle can be incorporated.

ODIM Brooke Ocean can supply CTD Handling Systems suitable for every size of payload and host vessel. Contact us today to discuss your requirements!
