Project Overview

The offshore oil platform in the Sanya sea area of the South China Sea is in a typical marine monsoon climate zone, with frequent sea fog, water vapor turbulence and frequent low-visibility weather. Offshore platform hoisting operations and helicopter personnel transportation have extremely high requirements on atmospheric visibility. Once foggy and low-visibility weather occurs, visual operation will be severely restricted, easily triggering major safety hazards.

Aiming at the problem that traditional manual visibility observation is difficult to quantify and cannot be monitored continuously in real time, Qingdao Hotech Automation provides a marine professional visibility monitoring solution for the Sanya offshore oil platform. The self-developed marine visibility sensor is deployed on site to realize automatic, quantitative and all-weather monitoring of offshore atmospheric visibility and sea fog changes, helping the platform build a perfect low-visibility weather early warning mechanism.

On-Site Equipment & Technical Features

The Hotech marine visibility sensor adopted in the project is optimized and upgraded for offshore high-corrosion and high-humidity environments, breaking the limitations of ordinary land visibility equipment in marine application.

The sensor adopts forward scattering optical detection principle, which can accurately capture the concentration of sea fog, water vapor and suspended particles in the air, and output real-time and accurate atmospheric visibility numerical values. It realizes quantitative evaluation of foggy days, hazy days and other low-visibility working conditions, and provides intuitive and reliable data support for offshore operation management and safety approval.

In terms of environmental adaptability, the equipment has excellent sea fog erosion resistance and dust and water splash resistance. The whole machine adopts marine anti-corrosion structure and special coating technology, which can effectively resist the erosion of sea salt deposition and strong sea wind. It can operate stably for a long time in the open-air harsh environment of offshore platforms without frequent manual maintenance.

Cooperated with the supporting data control cabinet, the visibility monitoring data can be displayed locally in real time, automatically stored and archived, and synchronously uploaded to the platform central control system. The system supports ultra-low visibility threshold early warning, which can timely remind the management side to suspend high-risk operations such as hoisting and helicopter takeoff and landing, and eliminate potential safety hazards in advance.

Core Solved Pain Points

1. Real-time quantitative monitoring instead of subjective manual evaluation: Realize digital visibility data output, avoid the uncertainty and subjectivity of manual visual inspection, and make operation safety judgment more standardized and accurate.

2. 24-hour unattended continuous monitoring: It can operate normally at night and in foggy weather, make up for the monitoring blind area of manual work, and realize full-time coverage of offshore meteorological safety monitoring.

3. Highly adapted to offshore extreme working conditions: Professional marine anti-corrosion design, suitable for long-term operation in South China Sea high salt spray environment, with strong stability and low later maintenance cost.
