Regulations & Compliance
Environmental requirements continue to evolve across the maritime industry. DEC Marine helps shipowners, OEMs, and operators understand regulatory requirements, evaluate compliance strategies, and prepare for future developments.
Environmental regulations influence vessel design, operation, maintenance, and long-term investment decisions. Whether planning a newbuild project, evaluating a retrofit, or preparing for future requirements, compliance must be considered throughout the operational lifecycle.
DEC Marine combines proven emission control technology with extensive regulatory expertise to help customers reduce risk, simplify decision-making, and maintain long-term compliance.
The International Maritime Organization (IMO) regulates NOx emissions from marine diesel engines through a tiered framework that has become increasingly stringent over time.
DEC Marine has worked with marine emission control through multiple generations of IMO regulations. Today, meeting Tier III requirements typically requires advanced aftertreatment technologies such as SCR systems combined with reliable control and monitoring capabilities. DEC Marine has delivered Tier III-capable solutions since long before the regulation became mandatory.
Introduced the first global limits on NOx emissions from marine engines.
Significantly reduced allowable emission levels and became the standard for many vessel categories.
The most demanding NOx regulation currently in force, requiring substantial emission reductions within designated Emission Control Areas (ECAs).
No two vessels face exactly the same operational requirements. Engine type, vessel design, operating profile, available installation space, and future regulatory exposure all influence the most appropriate compliance strategy.
DEC Marine helps customers evaluate compliance requirements, assess retrofit opportunities, plan newbuild integrations, and develop emission reduction strategies aligned with both operational and regulatory objectives. By combining technical expertise with long-term lifecycle planning, we help operators make informed decisions that support compliance today and prepare for future requirements.
Documentation
Meeting regulatory requirements requires more than achieving target emission levels. It also requires proper documentation, testing, certification, and verification. Our certification support covers:
Emission control is ultimately about delivering measurable results under real operating conditions. DEC Marine solutions are designed to reduce:
Our SCR systems can achieve NOx reduction rates of up to 98%, depending on application and operating conditions. Those results are supported by decades of operational experience across marine, offshore, and industrial applications.
