Marine activities

From cargo ships to cruise liners, naval vessels to offshore units – marine engines operate in some of the world’s most demanding environments. Harsh conditions, limited space, strict class requirements, and tight timelines make emission control a true engineering challenge.

Clean Compliance at Sea – Powered by DeepBlueLAB NOx and SOx

At LAB, we meet this challenge head-on – with tailor-made solutions with our SCR system that reduce harmful NOₓ emissions by over 95% and with our Marine scrubber that is able to reduce SOx emissions by over 97% and DeDust performances of 60 to 80% help protect both air quality and marine ecosystems.

Designed for Maritime Realities

The sea never stands still – and neither do ship engines. Fluctuating loads, vibrations, swells, and dynamic operating profiles are the rule, not the exception. That’s why DeepBlueLAB™ NOx and SOx systems are engineered for flexibility and resilience – across all vessel types and operating scenarios:

• All vessel types – ferries, cruise ships, tankers, naval vessels, fishing fleets, offshore support units, and power ships
• Newbuilds or retrofits – seamless integration in both
• Any engine brand and size – from 500 kW to 70 MW, 2-stroke or 4-stroke
• All fuel types – diesel, HFO, MDO, LNG, ammonia, dual-fuel, biofuels, and more
• Flexible reactor design – inline or offline, compact modular layouts for tight engine rooms
• Complete scrubber design – inline or offline scrubber,
• Flexible scrubber configuration: Open loop, close loop and hybrid with a fully adapted layout for ship configuration
• ATEX-compliant options for hazardous zones
• Low-maintenance concept with long service intervals for maximum uptime
• Fast-track engineering to meet strict docking schedules

Because at sea, systems must perform autonomously – no room for failure, no outside help.

Catalyst Expertise – The Heart of Every System

In marine SCR systems, the catalyst is the core. Its correct selection and configuration determine whether a system simply runs – or truly delivers.

At LAB, our in-house specialists bring over 30 years of catalyst expertise considering every parameter – from fuel type, exhaust composition and load behavior to temperature profiles and urea quality – to define the most effective solution for your vessel.

We don’t guess – we calculate, test, and optimize.

That’s what makes our systems efficient, robust, and regulation-ready.

Proven Expertise in SOx Reduction

With over 70 years of experience in flue gas treatment and heat recovery, LAB has built a strong reputation for technical excellence and reliability. This deep-rooted expertise is the foundation of our DeepBlueLABSOx solutions, which are engineered to drastically reduce sulfur oxide emissions.

Its deep industry knowledge and engineering capabilities enable LAB to meet the evolving demands of its clients and the stringent requirements of the maritime sector – ensuring that every system is prepared for both today’s regulations and tomorrow’s challenges.

By delivering high-quality and tailored solutions, LAB has ensured its ability to supply to the maritime industry an effective and reliable system.

Navigating Legislation with Confidence

The global maritime sector faces increasingly strict emission limits, including:

• IMO Tier III for NOₓ in NECA zones
• Norwegian Fjord regulations and eligibility for the NOx Fund
• IMO Sulphur limitations in fuels n SECA zones
• MED certificates for EU emission limits
• Local port and harbor restrictions
• Upcoming carbon intensity and GHG-related rules (e.g. CII, EU ETS)

We also ensure compliance with MARPOL Annex IV through complete EIAPP certification – Scheme A or B – and full onboard verification with certified measurement equipment. Our close cooperation with all major classification societies ensures smooth certification from design to final documentation.

LAB guides you through this complexity – with systems that are fully compliant, future-proof, and class-certified.

We Don’t Just Ship Boxes – We Stay Onboard

Our role doesn’t end when your system is delivered – that’s just the beginning.

We support your crew and operations every step of the way:

• Onboard installation and commissioning
• Remote monitoring and diagnostics
• Training by our experts, so your crew becomes the expert
• Maintenance contracts and system optimization (e.g. urea tuning)
• Global service network for fast response wherever you dock

We understand the operational realities of marine projects – from tight timeframes to remote locations – and we work efficiently to get your vessel back to work fast.
