In-situ Observation Platform-Highlander

In-situ Observation Platform

Developed for complex offshore seabed environments, this fixed seabed in-situ observation platform is a core piece of equipment for stationary underwater monitoring. It can effectively withstand risks such as displacement and damage caused by ocean current scouring, fishing gear dragging, and unstable seabed terrain. The platform adopts a bottom-mounted, stable anti-drag structure and integrates multiple types of high-precision sensors, intelligent control, energy, and communication modules. Under unattended operation, it can continuously and reliably collect multi-dimensional environmental data from the seabed and near-bottom waters, including hydrology, water quality, acoustics, geology, and ecology.

Product Series

(1) HLD-LCC300 Composite Seabed Base

Featuring a modular design of composite foam buoyancy chamber and concrete base, it can carry marine sensors and provide stable and reliable seabed in-situ monitoring support for nearshore observation networks.

Operating Water Depth: 300 m (customizable for greater depths)	Buoyancy Chamber Dimensions: 1.15 m × 1.15 m × 0.42 m	Buoyancy: 123 kg
Buoyancy Chamber Weight: 114 kg (in air)	Base Dimensions: 2 m × 2 m × 0.4 m	Base Weight: 1930 kg (in air)

(2) HLD-AL300 Conical Bottom-mounted Self-contained Seabed Base

The overall structure adopts a conical bottom-mounted stable anti-drag design. Its large-base-diameter conical profile enhances seabed grip and helps resist the impact of currents and trawling. The self-contained design integrates energy and data units, enabling independent long-term in-situ observation without cables, with convenient deployment and strong stability.

Operating Water Depth: 300 m (customizable for greater depths)	Overall Dimensions: Base diameter approx. 1900 mm	Main Frame Material: Lightweight aluminum alloy
Buoyant Material Density: 0.38 g/cm³	Supported Equipment: ADCP, CTD, and other low-power sensors

(3) HLD-TI6000 Seabed In-situ Observation Station

A modular energy-storage junction observation platform designed for long-term deep-sea observation and coordinated operation of multiple devices. Different from self-contained seabed bases, it features a built-in high-capacity energy storage system, providing stable power supply and data transmission interfaces for various general-purpose underwater observation devices.

Maximum Operating Water Depth: 6000 m	Main Body Material: Titanium alloy	Energy Storage Capacity: 500 Ah–2000 Ah (customizable)
Power Output: DC 12 V / 24 V / 36 V (customizable)
