Ship owners and operators need to trust that their lubricants can deliver under any circumstances. Our marine lubricant additives are designed to protect and enhance performance for a variety of engines. We work closely with our customers and OEMs to support the marine value chain as we approach IMO 2020.

adding up™ in marine lubricant additives

As a leader in marine lubricant additive technology, we leverage relationships with original equipment manufacturers and monitor key industry trends in the marketplace. This enables us to deliver timely new products to help meet evolving lubrication needs and emission regulations.

Our innovative technology, enduring relationships and exceptional reliability continue to add up for our customers. Oronite offers a technical team dedicated to marine additive development and reliable logistic support through a global supply capability. We make continuous investments in our manufacturing plants, for example in Asia Pacific, where we have a strong presence. Our robust global product line has undergone extensive field testing and offers components and formulated packages customized for marine applications. And we have unique relationships with key industry stakeholders and superior knowledge of the market, which enables collaboration and sharing insights with our customers.


The marine industry is constantly facing new challenges. With the emergence of stricter emission regulations, lower-sulfur fuels have become a significant part of the marine fuel market. More complex engine designs are being introduced that deliver power at reduced emissions. Slow steaming has become an accepted practice to reduce both emissions and fuel consumption. For the marine industry, being able to rely on lubricants is now more important than ever.

maximizing value with MAPS™

Developed from the latest additive technology, Chevron Oronite's Marine and Powergen System (MAPS) is a solution to help our customers maximize value for their marine businesses. The MAPS portfolio consists of five additive packages that can be used to blend a complete slate of oils for marine and power generation applications. With IMO 2020 approaching, Oronite will unveil four new additive packages. MAPS technology has been tested by a proven in-house development program as well as extensive testing in real world, field conditions. MAPS additive technology is suitable for the latest generation of marine and powergen engines, as well as older engine types. Additional benefits include the following:

MAPS is another example of Oronite's unparalleled commitment to its customers and to the marine industry.

Traditionally, the marine market has used heavy fuel oil, which is characterized by its high-sulfur content. With the introduction of emission control areas, the use of low-sulfur fuels has increased significantly. Oronite has developed customized marine additive formulations that contribute to improve the performance of different types of engines:

These types of engines are typically used as:

By applying our expertise and industry network, such as our close original equipment manufacturer (OEM) relationships, we can provide insights into the trends and market drivers in the marine industry and offer solutions that help give our customers a competitive advantage.

impact of IMO sulfur cap in 2020

Looking ahead to the year 2020 and beyond, the International Maritime Organization (IMO) is firmly committed to reducing the sulfur content in bunker fuels from 3.5 wt% to 0.5 wt%. Oronite continues to study the potential impact of the related regulations and is monitoring the response from refining and shipping industries, as well as the actions taken by the authorities related to implementation and enforcement. An emerging trend is that the shipping industry will have a range of options for compliance with these new regulations; including installation of on-board scrubbers, switching to alternate low-sulfur fuels, or adapting to liquid natural gas (LNG) fuels. Oronite is working to develop and commercialize a broad range of additive products for any option a shipper may choose in order to meet these changing marine lubricant requirements.

meeting changing performance requirements

The current business environment is creating pressure on ship and power generation operators to economize by seeking options to reduce fuel consumption, reduce lubricant costs and improve engine efficiencies. These current and future trends will combine to create the need to identify, develop and commercialize improved lubricants to address the changing performance requirements demanded by changes in marine engine designs and expanded slate of alternate marine fuels such as distillate, LNG and low-sulfur fuel oils.

the role of engine and field testing

Major changes are underway for marine trunk piston engine oils (TPEOs). The use of distillate fuels in combination with the increased application of the API Group II base oils, the demand for longer drain intervals and lower lubricants consumption present significant technical challenges. Meeting the needs of the changing market requires new additive and formulating technology that meets the most demanding performance requirements.

CIMAC congress participation

Conseil International Des Machines A Combustion (CIMAC) is the international council on combustion engines. It is a worldwide, non-profit association with members representing 26 countries in America, Asia and Europe. Chevron Oronite has collaborated with CIMAC to publish the following papers.


Emission regulations can indirectly affect the lubrication requirements for large-bore diesel engines. The impact of low-sulfur distillate fuel on the lubrication of 2-stroke crosshead diesel engines is examined.


Oronite, along with Johnson Matthey and ExxonMobil, is helping the marine industry understand whether lubricant requirements will need to change.


Engine and field testing have become an integral part of lubricant and additive development for trunk piston engine oils.
