In the challenging marine operations environment, reliability and safety are paramount. One important aspect that contributes to delivering both is the Fixed Gas Sampling System, a precious technology for gas level measurement and control in high-risk and confined areas. Supplied by top OEMs like HANLA, the system is the pillar of preventive safety on marine vessels and offshore operations.

HANLA’s fixed gas sampling is designed for gas control in all tanks, void spaces, the pump room, or houses adjacent to the cargo storage tank and handling systems. In order to detect any gas concentration level over programmable limits and to monitor visible & audible alarms, consequently these areas are controlled by the suction process sampling on one or more common sensor(s)  as well as by individual local sensors. To continually monitor enclosed or hazardous areas for toxic gases such as H2S, LEL, and O2. The systems not only provide real-time data but also trigger alarms or automated responses whenever gas concentrations exceed safe levels. Their functions play a major role in saving lives, enabling business continuity, and ensuring compliance with maritime safety regulations.

Key Features of Fixed Gas Sampling Systems

Fixed gas sampling systems are designed to be efficient, robust, and flexible, essential for maritime environments where conditions are unpredictable and safety is paramount.

Centralised Analysis Unit

This cabinet-based unit holds all key components of the system and contains:

• Suction sampling mechanism
• Gas sensors
• Pneumatic elements such as pumps, solenoid valves, Water trap filter & pressure sensor
• An electronic module for alarm control and real-time measurement

Smart Control Panels

The control units typically installed in bridge or engine control rooms are equipped with

• Large LCD screens
• Clear operation status lamps
• Audible beepers
• Dry contact output relays to enable automation and alarm escalation
• System configuration using user-friendly keyboards

Modular and Scalable Design

Marine uses are different, and so are the requirements for safety. The modular nature of fixed gas sampling systems provides:

• Simple upgrading
• Simple maintenance
• Simple expansion for more detection zones

Multi-Gas Detection Capability

These systems accommodate up to seven gas sensors, directly or by suction lines, that enable measurement of gases like

• H₂S
• LEL
• O2

Remote Monitoring and Automation

Fixed systems can be linked with vessel management systems so that

• Remote monitoring of gases in control rooms
• Automatic ventilation or shutdown modes on crossing critical levels

Installation Aligned with Safety Standards

A set of Suction Sampling Accessories 

• A set of suction sampling accessories composed of safety chambers, non-return valves, Flame arrestors, and Shut-off valves.
• Each channel flow regulating valve allows for identical flow whatever is of the length of the line, for the best efficiency of the system.

Benefits of Fixed Gas Sampling System 

The benefits of a good fixed gas sampling system go way beyond regulatory compliance; they make sea operations safer and smarter.

24/7 Real-Time Protection

24/7 real-time monitoring prevents gas dangers from being missed, even where there is no one around.

Early Warning and Emergency Response

Automatic alarm and automatic response provide precious time for staff to respond safely.

Regulatory Compliance

Assists vessels to remain in line with safety regulations and avoid the possibility of fines, downtime, or worse—crashes.

Cost-Efficiency

Saves on expensive incidents and prolongs asset life by identifying threats before they get out of hand.

Improved Crew Confidence

Emphasize that there is an effective detection system running that boosts morale and improves performance.

Flexible and Scalable

From the retrofitting of a small ship to the installation of a complete system on a newbuild, fixed gas sampling systems are scalable and adaptable.

The HANLA’s system supplied through KDU World are so designed for fail-safes and redundancy so that uptime is delivered in adversarial sea conditions. The secret is always in creating something that will not only pass compliance but also take into account the realities in offshore and maritime environments.

KDU World Enabling Maritime Safety With Intelligent Gas Sampling Solutions

With changing marine safety regulations, Fixed Gas Sampling systems play a crucial role in intelligently running ships. It is now mandatory to employ these technologies in all ships and offshore platforms dealing with hydrocarbons, chemicals, or inert gases.

We are delighted at KDU World to be part of a safer and smarter maritime future. In the UAE, KSA, Oman, and Nigeria, KDU has established a reliable reputation for delivering marine equipment and safety systems that meet the most stringent industry standards.
