OceanGate owned three submersibles. The Cyclops 1 and Titan submersibles were launched and recovered from a dry dock-like "Launch and Recovery Platform" that could be towed behind a commercial vessel. Once the platform and submersible reach the target location, the platform's flotation tanks are flooded and it sinks below the surface turbulence to a depth of 9 m (30 ft). The submersible then lifts off for its underwater mission. Upon the submersible's return to the platform, the flotation tanks are pumped out and the platform can be taken back into tow or brought aboard the host vessel. This allows OceanGate to use vessels without human-rated cranes.[18] The platform is approximately 35 ft (11 m) long and 15 ft (4.6 m) wide and can lift up to 20,000 lb (9,100 kg);[19] it is based on a concept developed by the Hawaii Undersea Research Laboratory.

母船拖曳一个dry dock类似干船坞的东西，泰坦号就在干船坞里。到了地方，干船坞释放泰坦号。

泰坦号下潜到泰坦尼克号残骸附近，去程就要2小时，回程也差不多这个时间，游览观光时间大约3-4小时，肯定要绕着残骸（船长度300多米，断成两截，相距600米以上）以及8*4.8公里的碎片散落带来回溜达着参观游览的。 拖着线缆是不可能做到的。

& `: l' p) f6 m8 nOceanGate's calculations showed the cylinder that formed the center section of the crew compartment should have a wall thickness of 4.5 in (114 mm), which they rounded up to 5.0 in (127 mm); it consisted of 480 alternating layers of pre-preg unidirectional cloth, laid in the axial direction, and wet-wound filament, laid in the hoop direction. The cylinder was built in 2017 and cured at 137 °C (279 °F) for 7 days.[29] The entire pressure vessel consisted of two titanium hemispheres, two matching titanium interface rings, and the 142 cm (56 in) internal diameter, 2.4-meter-long (7.9 ft) carbon fiber wound cylinder—the largest such device ever built for use in a crewed submersible.[33] One of the titanium hemispherical end caps was fitted with a 380 mm-diameter (15 in) acrylic window.[29] In addition to the crew compartment, Titan included a landing skid structure and outer glass fiber composite shell, both bolted to the titanium interface rings.[29] Overall, the Titan was 670 cm × 280 cm × 250 cm (22.0 ft × 9.2 ft × 8.2 ft) and weighed 9,525 kg (21,000 lb) with a maximum payload of 685 kg (1,510 lb). It moved at up to 3 kn (5.6 km/h; 3.5 mph) using four electric thrusters, arrayed two horizontal and two vertical. The vessel carried sufficient oxygen to sustain a full complement of five people for 96 hours.5 O) M" D g* \( Z
