Welcome to Zuudee BYD Titanium!

Titanium is widely used in sea-related industries due to its exceptional resistance to corrosion and erosion in saltwater environments. This makes it an ideal material for applications that require durability and reliability in harsh ocean conditions.

One of the most common applications of titanium in sea-related industries is for marine hardware, such as propeller shafts, marine exhaust systems, and boat fittings. These components are exposed to constant exposure to saltwater, which can quickly corrode and degrade traditional materials. However, titanium's corrosion resistance ensures that these components can withstand the harsh marine environment and provide reliable performance for years to come.

Another important application of titanium in sea-related industries is in offshore oil and gas exploration and production. Titanium is used in various components, such as pipes, valves, and heat exchangers, due to its ability to resist corrosion caused by seawater and corrosive chemicals. This helps to ensure the safety and reliability of offshore drilling and production equipment.

In addition to these applications, titanium is also used in seawater desalination plants, underwater mining equipment, and other sea-related applications where corrosion resistance and durability are essential.

At ZUUDEE, we specialize in providing high-quality titanium products for searelated industries. Our products are designed and manufactured to meet the specific needs of our customers in these industries, ensuring reliable performance and long-term durability in harsh marine environments.

CASE STUDY:

DEEPWATER TETHER CLAMP

The titanium clamps were designed to tether two control umbilicals that run from subsea wellheads to a surface FPSO in approximately 3,000m of water, a particularly challenging requirement as the diameter of the subsea umbilical will change over time during and post installation. An innovative, compliant clamp solution was therefore developed using titanium rods as the tension mechanism in order to reliably secure the control umbilicals for at least 20 years.

Deep sea pressure-resistant shell and deep sea electronic compartment

subseatitanium.com

The titanium underwater pressure shell is an early self-developed product of zuudee.

It has a history of more than 10 years. The initial product is a simple cylindrical pressure shell design and processing, which is applied to our company's own Shallow sea marine engineering projects. Later, as the business of zuudee's marine engineering projects increased, and the launch of our company's selfdeveloped products, the demand for pressure-resistant shells and the amount of processing continued to increase.

Customers for marine scientific investigations also ordered deep-sea durable shells with Zuudee. Our company has formed a one-stop service for pressure shell material selection, structural design, force analysis, processing and manufacturing, assembly, and pressure testing.

The structural form of the pressure shell is also increasing, from the initial cylindrical pressure shell, the hemispherical spherical cover plus the circular pressure shell, the spherical pressure ball, and the rectangular underwater shell suitable for shallow water applications or oil-filled structures. The cabin, to the irregular shape required by the customer, even the underwater pressure-resistant hull structure, and the deep-sea conical terminal structure. The pressure-resistant chamber can be in the form of a dry chamber according to customer requirements, or vacuumized, or an oil-filled internal and external pressure balance structure.

Temperature & Pressure Recorder with Inductive Modem Zuudee

The recorder is a high-accuracy temperature (pressure optional) recorder with built-in Inductive Modem. The modem provides reliable, low-cost, real-time data transmission for up to 100 sensors — using a single, plasticcoated, steel mooring wire. The sensors clamp anywhere along the inherently rugged mooring wire; expensive and potentially unreliable multiconductor cables are not required.

The sensor moorings are easily reconfigured to meet changing deployment scenarios. Because sensor positions can be altered (or sensors added/deleted) by sliding and re-clamping sensors on the wire, there is no need to design and purchase a new cable with different breakout locations. The systems permit data telemetry from sensors located anywhere along the mooring wire, making them far more efficient and flexible than acoustic modem types that place serious demands on battery capacity and return data from a single underwater position only. At the surface (typically in a buoy), a Surface Inductive Modem (SIM) completes the link between the sensors and a computer or data logger. Data from the sensor string can be stored and transmitted via satellite link, cell phone, or radio telemetry. As insurance against real-time data loss, the sensor simultaneously stores data in its non-volatile memory.

The thermistor, has a long history of exceptional accuracy and stability; drift is typically less than 0.002 °C/year. Two thermistor configurations are offered: thermistor embedded in titanium end cap (25.0-second time constant) for rugged conditions; or external thermistor in pressure-protected sheath (0.5-second time constant) for fast sampling.

www.subseatitanium.com

Email:info@bydtitanium.com

COMMUNICATIONS AND INTERFACING

The bottom of the insulated mooring wire is grounded to seawater, typically via a padeye swaged to its steel core; a padeye at the top completes a conductive loop through the water. A coupling transformer — similar to the one in the sensor but clamped to the mooring cable just under the buoy — connects to the SIM (SIM and transformer available separately). Communication with the SIM is full-duplex RS-232C or half-duplex RS-485.

subseatitanium.com

Each sensor has a programmable address. Upon receipt of a wake-up command, the SIM sends a tone for 2 seconds, waking all sensors on the cable. When a sensor receives a command, it replies and then returns to listening.

DATA STORAGE AND UPLOAD, AND BATTERY ENDURANCE

The sensor has a 4 Mbyte non-volatile FLASH memory. Temperature and time are always stored (total of 7 bytes/sample); pressure adds 2 bytes/sample. Data extraction can be done via the internal connector. Binary upload capability provides fast upload of large data sets.

CONFIGURATION

A standard sensor is supplied with titanium housing for depths to 600 meters, internal thermistor, and wire guide and clamp.

Options include:

• External thermistor in pressure-protected sheath

• Titanium housing for depths to 10,500 meters

• Strain gauge pressure sensor - available in eight pressure ranges, to a maximum depth of 7000 meters

• Net fender / fairing - conical ends are shaped to shed fishing lines and nets

Titanium plug-and-socket component for protecting deep-sea cables

subseatitanium.com

SUBSEATITANIUM.COM

info@bydtitanium.com

Due to the high pressure in the deep sea, deep sea equipment generally needs to withstand the high pressure and its fluctuation. Moreover, multiple sophisticated detection devices are typically installed on the deep sea equipment, and these detection devices need to be connected through cables to ensure their normal detection and data transmission.

In actual assembly, different devices need to be connected through cables. The conventional connection method is to fix the cables into circular sleeves on different devices, and finally connect and fasten the sleeves on each device so that the cables between devices are protected by the sleeves.

However, under the great pressure fluctuation and impact at the seabed, it is prone to cause twisting between the sleeves, resulting in the twisting of the cables inside the sleeves, causing cable breakage problems and affecting the smooth progress of deep sea operations, as well as causing large operation and maintenance costs.

Zuudee has invented a titanium plug-and-socket component for protecting deep-sea cables. The socket component includes an upper support and a lower support that correspond to each other with a hollow passage, and symmetrically arranged docking positioning structures that are identical in structure on the upper and lower supports. The outer surfaces of the upper and lower supports are covered with positioning and fastening components that are cooperatively engaged with the docking positioning structures and maintain the relative positioning of the two supports.

The titanium plug-and-socket component achieves a secure joint between the upper and lower supports by employing the docking positioning structures and positioning and fastening components, which limit the twisting of the two supports under the influence of high deep-sea pressure and improve the stability of cable operations during deep-sea operations. The joint also facilitates the rapid inspection or replacement of cables or components of equipment by disassembling the upper and lower supports, thereby improving the convenience of subsequent operations and significantly reducing operating costs.

Subsea Graphical Datalogger

The Flow Subsea Graphical Datalogger builds on the capability of existing Flow Subsea Displays.

The SGD is designed to display the total number of sensor actuations on Subsea tools, modules & installations without the need for a complex control system or datalink.

Critical operations can be monitored and now data logged using an internal 32Gb Mass Storage Device (MSD). Diagnostic capability allows the operator to test / operation with customisable sensitivity level set-up.

Any displayed image automatically flips upright via an in built accelerometer and also logs this occurrence.

Zuudee BYD Titanium for offshore oil and gas drilling subseatitanium.com

Titanium is used in the offshore oil drilling industry for various purposes due to its exceptional strength, corrosion resistance, and lightweight. One of the main uses of titanium in this industry is for manufacturing drilling equipment, including drill bits, casing, and wellheads.

Drill bits made of titanium are much more durable and resistant to wear and tear than traditional steel drill bits, which can be essential when drilling through tough rock formations.

Titanium is also used to make casing and wellheads, which provide structural support to the well and prevent leaks.

Another common use of titanium in the offshore oil drilling industry is for manufacturing pipes and tubing used in subsea operations. These pipes must withstand high pressure and corrosive seawater, and titanium's resistance to corrosion makes it an ideal material for these applications.

Titanium is used in the construction of offshore platforms, which must withstand harsh marine environments. Titanium's high strength-to-weight ratio makes it a lightweight but strong material for use in these structures.
