Titanium: The ultimate choice for marine service
NATURAL IMMUNITIES AND RESISTANCES TO SEAWATER
Titanium’s remarkable ability to resist corrosion and erosion in seawater is due
to its unique protective oxide film, which forms spontaneously in the presence
of even trace amounts of oxygen. If scratched or damaged, the highly
adherent film instantly heals itself.
Seawater corrosion immunity: Titanium is immune to corrosive attack in
all natural and harsh waters, including sea, polluted, brackish, fresh and high
purity waters, to 600o
F. Sulfides, sulfates, carbonates, and chlorides do not
affect it.
Seawater erosion resistance: Titanium naturally resists erosion by high
velocity seawater, up to 120’/sec, in the absence of suspended solids. Under
sand-laden seawater conditions, which are extremely detrimental to copper
and aluminum based alloys, flow rates can be as high as 15’/sec.
MIC immunity: There has never been a reported case of microbiologically
influenced attack on titanium, which makes it unique among common
engineering metals.
Biofouling: Where copper-nickel alloy life expectancies are less than
acceptable due to biofouling, titanium’s oxide film is uncompromised by
marine deposits. Biofouling can occur but is effectively controlled by high
water velocities, or by chlorination, sponge ball cleaning, ultraviolet radiation
or ozone generation.
Crevice corrosion & pitting immunity: At temperatures less than 180o
F
(82o
C) crevice corrosion and pitting are totally absent, even if marine deposits
form.
SCC & corrosion fatigue resistance: In all seawater services, commercially
pure titanium is essentially immune to stress corrosion cracking and does not
suffer significant loss of fatigue properties.
Galvanic corrosion: Titanium is not subject to galvanic corrosion in seawater,
but may accelerate corrosion of the other member of the galvanic couple.
Non-toxic, non-pyrophoric: Titanium does not display any toxicity toward
marine organisms or mammals and tolerates extreme temperatures (1832o
F,
1000o
C).
Hydrogen uptake: The oxide film is an excellent barrier to hydrogen gas
intrusion.
UNIQUE MECHANICAL PROPERTIES
Strong: Titanium has a significantly higher yield strength and
strength-to-weight ratio than copper nickel alloys or stainless steels.
Light weight: Titanium is half the density of copper nickel alloys
and 55-57% that of stainless steels. This accounts for a minimum
50% weight savings in service water piping throughout the ship.
Flexible: Titanium’s low modulus plus its high density make it
highly shock resistant.
High operational thermal conductivity: Thermal conductivity
for titanium is up to 30% higher than stainless steels. Although
thermal conductivity is lower than in copper-nickel, titanium’s
reduced wall thickness and lack of biofouling allows titanium heat
exchangers to perform as efficiently, or even more efficiently, than
those of copper-nickel.
Non-magnetic: Titanium is ideal for use in applications sensitive
to interference, such as housings for electronic equipment.
Easy to fabricate: Titanium plate, sheet, pipe and tubing are
readily cut, bent and drilled in shipyard on on-ship environments,
using the same equipment and techniques used for stainless
steels and nickel base alloys. Tungsten Inert Gas welding can
be performed without a vacuum and GMA, plasma resistance,
friction, electron beam, laser and pressure welding are also used.
TYPICAL ALLOYS FOR MARINE SERVICE
With the wide selection of titanium alloys available, optimum choice for a given
marine application is almost always possible. Selection for is governed by
strength and formability properties, corrosion resistance, or both. The most
common grades for salt water service are Grades 1, 2, 7, 11, 12, 16 and 17,
with Grade 2 the most widely used. There are also a variety of other grades
for various marine applications.

Zuudee BYD Titanium Clamp for Offshore and Subsea Industry
subseatitanium.com
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 self-
developed 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, plastic-
coated, 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.
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.
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
It relates to the field of deep-sea
operations technology, and
particularly relates to a titanium
plug-and-socket component for
protecting deep-sea cables.
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.

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.

Sealing: The Series Titanium might be the best sealed subsea connector on the market. All critical interfaces, including
bulkhead seals, glass-to-metal insert seals, mating interface bore seals, and face seals are fully redundant ensuring 10K PSI
protection, even in the event of a single-seal failure.
Mating: Zuudee utilizes a modified UNC (coarse) mating interface with added clearance to reduce bio-fouling and facilitate
rapid-advance mating. The marine bronze engaging nut on the plug is equipped with wrench flats as well as knurling and
is less susceptible to galling than standard steel engaging nuts. Polarized keys and keyways prevent both thread damage
and mismating.
Ease-of-Use: Multiple PBOF backshell indexing points, indexable flange FCRs, full-mate inspection ports, retractable engaging
nuts, and other features make it the most user-friendly subsea connector on the market.

Highly Accurate Consistent Heave
Tested on a highly accurate hexapod simulating sea
condi-tions, Real-time heave accuracy has been
confirmed beyond specifications, as 2.3 cm.
Test conducted at the IFREMER Institute (France).
Full test available on www.subseatitanium.com
ADVANCED REAL TIME HEAVE
No need to enter wave frequencies, adjusts to the sea
state to compute the best heave data and deliver it on up
to four different locations.
HIGH ACCURACY DELAYED HEAVE
The delayed heave runs an internal zero phase filter which
passes over the recorded heave data to increase its accu-
racy ( 2.5 cm). It is especially relevant in cases of long
period swell, where real-time heave reaches its limits.
