Gas Detector for Marine Industry – Riken Keiki’s Vessels & Offshore Gas Detection Systems

Riken Keiki is a leading Gas Detector manufacturer in the Marine Industry, trusted by shipbuilders, ship operators, and offshore platforms across the world. For over 80 years, we’ve built gas detection systems that withstand the intense environments at sea while delivering consistent performance. Salty air, harsh vibration, moisture, and limited space are issues faced by marine crews daily, and these elements also pose a challenge to ordinary systems. From tankers and cargo carriers to port terminals and offshore rigs, we offer dependable solutions that protect crews and meet safety rules set by international marine regulators.

Why Choose our Gas Detector for Marine Industry?

Fulfills Marine Safety Regulations

Every vessel must follow the IMO and SOLAS marine safety codes. These rules protect ships and those on board. Riken Keiki gas detectors meet those rules and regulations in the Marine industry. We supply devices that meet Marine standards.

Performs in Dangerous Marine Zones

Ships carry fuel and flammable cargo. These create hazardous zones labeled Zone 0 or Zone 1. Our gas detectors hold approvals such as ATEX and IECEx that allow them to function in these areas.

Resists Corrosion and Water Exposure

In marine industry conditions; its salty air damages metal, and moisture gets into every space. Our gas detectors for the marine industry are designed to use in such conditions. Every unit is tough and reliable.

Types of Gas Detectors for Marine Industry

Portable Gas Detectors

Our portable gas detectors hold the No.1 market share in the marine industry. They reliably detect low oxygen levels, toxic gases, and flammable gases, ensuring safety before personnel enter confined spaces. They meet maritime rules and regulations, including necessary MED certification for the marine industry, and offer a product lineup that addresses various gas detection needs on vessels such as O2, CO, H2S, flammable gases, CO2, and NH3.

Fixed Gas Detection Systems

Our gas detection systems feature proprietary sensors capable of measuring variable gases and are certified under the multiple international standards. (ATEX/MED/ABS/DNV/KR/RINA)

Specially designed for the marine industry, they have all the functions needed for on-board gas detection.

In the event of replacing a fixed gas detector, an aged internally installed gas detector can be substituted while retaining the existing panel – offering flexibility to match your budget and operational needs.

Applications of Gas Detectors for Marine Industry

Engine Room Safety Monitoring
Detect combustible gases (e.g., fuel vapors) and toxic gases (like carbon monoxide) around engines and fuel systems to prevent fire and explosion hazards.
Confined Space Entry Checks
Before personnel enter tanks, cargo holds, or ballast spaces, gas detectors verify safe air quality (O₂, flammables, toxic gases) to protect crew members.
Cargo Handling & Storage Monitoring
During loading/unloading of bulk chemicals, LPG, LNG, or hazardous cargo, portable detectors monitor for leaks and gas releases near pipelines and tanks.
Ballast Tank Gas Monitoring
Gas detectors check ballast tanks for hydrogen sulfide (H₂S), methane, or other gases formed by decaying matter or trapped vapors.
Pump Room & Bilge Area Surveillance
Monitor areas where oils, sludge, or organic material may generate dangerous gases, ensuring safe maintenance and operation.
Accommodation/Living Quarters Air Quality
Detects accumulation of toxic or flammable gases in cabins, mess rooms, and enclosed crew areas to maintain healthy environments.
Emergency Response & Leak Assessment
In accident or leak situations, gas detectors are used by response teams to identify hazardous concentrations quickly for safe decisions.
Offshore Platforms & Support Vessels
On drilling rigs, FPSOs, or supply vessels, detectors monitor for gas leaks around deck equipment, pipelines, and machinery spaces.
Refrigeration System Leak Detection
Gas detection around refrigeration or HVAC systems catches refrigerant leaks (e.g., ammonia) that could be toxic or harmful.
Personal Safety Gear for Confined or Hazardous Tasks
Portable personal detectors worn by crew during inspection, repair, or confined space activities provide real-time monitoring and alarm alerts.

Compliance and Certification

Our products follow marine safety rules and regulations. Certified to IMO MSC.1/Circ.1370 and SOLAS, they meet IEC 60079 standards. Vessels using Riken Keiki detectors stay compliant with ABS, DNV, Lloyd’s Register, and other classification groups. Explosion-proof designs work inside Zone 0 and Zone 1 rated spaces.
