Products
C-PINS
Zupt C-PINS
[Category: Subsea Survey and Metrology]
Zupt’s C-PINS is a high-accuracy subsea metrology tool that delivers fast, reliable, and cost-effective results without the need for traditional acoustic arrays. Designed for use at depths of up to 4,000 meters, it integrates an inertial measurement unit (IMU), pressure sensors, and optional aiding from USBL or DVL systems to perform precise measurements of subsea structures. Its compact size, single ROV connection, and quick deployment make it well suited for jumper metrology, pipeline surveys, and structure positioning. C-PINS can complete full metrology surveys in as little as 6 to 10 hours, with processed data typically delivered within 24 hours. This helps offshore teams reduce vessel time, improve accuracy, and make timely operational decisions.
3D Recon V2
Zupt 3D Recon V2
[Category: Subsea Inspection and 3D Data Visualization]
Zupt's 3D Recon V2 is a subsea stereo imaging system that produces high-resolution, geospatially accurate 3D models of what is seen subsea. Housed in a compact subsea enclosure rated for depths up to 4,000 meters, it features two high-resolution machine vision cameras and a high-performance MEMS IMU. By integrating inertial technology with imaging sensors, 3D Recon V2 can generate real-time sparse point clouds for navigation and quality control, as well as high-density 3D models that help engineers make informed decisions about the integrity of their subsea assets.
Integrated Robotic Total Station (iRTS)
Zupt iRTS
[Category: Offshore Surveying and Installation Support]
Zupt's iRTS offers the advantage of automatically tracking a prism with high accuracy up to 400m meters away. The solution is an integrated robotic total station, IMU, and RTK GNSS solution. This solution ensures precise tolerances are met by providing an absolute position for the tracked prism on the hammer as well as the rate of penetration of the monopile, making it an ideal choice for monopile installation operations. The data from the IRTS is real-time, time-tagged data with a known “time of validity” for each observation.
The iRTS system integrates a Leica TS16 robotic total station, a Trimble GNSS receiver, and a navigation-grade IMU. Purpose-built for offshore applications, it tracks prisms mounted on vibro-hammers during pile installation and provides real-time rate-of-penetration data to reduce pile run risk and ensure accurate final elevation.
HaloCAM
Zupt HaloCAM
[Category: Real-Time Subsea Visualization]
Zupt’s HaloCAM is a contactless, high-definition subsea monitoring system designed to provide precise, real-time awareness during offshore structure installation. By combining stabilized video with inertial navigation data, HaloCAM tracks the movement, heading, and orientation of subsea assets without the need to mount sensors directly on the structure. The system is compact, ROV-friendly, and well suited for challenging conditions where traditional sensor placement is impractical. Whether supporting monopile installation in offshore wind or critical positioning tasks in oil and gas, HaloCAM delivers clear visual feedback and accurate positional data to help operators make faster, safer decisions subsea.
Gyro Box
Zupt Gyro Box
[Category: Precision Alignment and Attitude Measurement Systems]
Zupt’s Gyro Box is built to provide accurate heading, pitch, and roll data during offshore wind installations, where precision matters most. Compact and easy to deploy, it helps crews quickly align monopiles and transition pieces without the need for bulky equipment or lengthy setup. The system is rugged enough for harsh offshore environments and delivers reliable data in real time, giving teams the confidence to move forward with each critical step. Whether it’s speeding up installation or reducing the risk of rework, the Gyro Box is a practical tool that keeps offshore wind projects on track.
Mux Lite
Zupt Mux Lite
[Category: Subsea Data Management and Sensor Networking]
Zupt’s Mux Lite is simply a compact network switch with serial and analog ports. Unlike conventional subsea multiplexers, this Mux Lite offers a simplified solution for scenarios where only a limited number of ports are required, making it a cost-effective and space-efficient choice. The user-friendly web interface eliminates the need for complex topside units; only a computer and 10GB ethernet switch on the surface vessel are needed for topside data communication.
As a subsea multiplexor, the Mux Lite provides reliable fiber optic data transfer through a single cable from subsea sensors to the surface. It also has an additional fiber port on the top end cap of the subsea unit, allowing it to be daisy-chained with other units to expand capabilities subsea.
Zupt’s VertiCAM offers a simple, visual way to determine monopile verticality in real time.VertiCAM is a ruggedized Lidar-Camera system tightly coupled to an Inertial Navigation System designed to provide real time data on the verticality of a monopile during the driving process. With an easy-to-read interface, installation teams can instantly interpret the pile’s heading and inclination from the deck or the bridge
Whether used as a standalone check or integrated alongside Zupt’s iRTS system for pile run monitoring, VertiCAM helps improve decision-making. It allows engineers and offshore personnel to observe changes in tilt and make immediate adjustments to ensure alignment with project tolerances.
