TeamTec History – Ejectors, BWMS & Marine Incinerators

18th Century – Maritime Heritage and Shipbuilding at Tangen | TeamTec

TeamTec’s history is rooted in a long-standing maritime tradition at Tangen in Tvedestrand, one of Norway’s historic industrial and shipbuilding sites. As early as the 18th century, the area was known for constructing sailing vessels, with shipbuilding activities continuing well into the 19th century.

This strong heritage in maritime engineering and craftsmanship forms the foundation of TeamTec’s modern expertise in marine technology, ejector systems, and environmentally friendly waste management solutions for the global shipping industry.

1961 - Origins at Tangen and the Foundation of Golar Metall | TeamTec

In 1961, Tvedestrand Iron Foundry (Tvedestrand Jernstøperi) was established at Tangen with support from Gotaas Larsen. The company later evolved into Golar Metall, which became a leading supplier of ejector systems and marine incinerators for the global shipping industry.

This early industrial foundation at Tangen laid the groundwork for decades of innovation in maritime environmental technology. Golar Metall’s expertise in ejectors and waste handling systems would later play a key role in the development of advanced marine solutions and the eventual formation of TeamTec.

1984 - Founding of TeamTec AS and Strategic Industrial Expansion | TeamTec

TeamTec AS was founded on May 17, 1984, by Trygve Eriksen, Einar Eike, Jens Martin Marcussen, Ole Jørgen Olsen, and Erling Holm from Top Management in Golar Metall. From the outset, the company established a strong industrial foundation within maritime and environmental technology.

As part of its early growth strategy, TeamTec acquired both the foundry and machine factory operations from Golar Metall, strengthening its production capabilities and technical expertise.

Since its inception, TeamTec has also maintained a long-standing international partnership with Nanjing Luzhou Machine Company Ltd. (NLMC) in Luzhou, China. This collaboration has supported global manufacturing, technology development, and the delivery of reliable marine waste management solutions.

1996 - Establishment of Headquarters at Tangen | TeamTec

In 1996, TeamTec acquired the administration offices at Tangen, which became the company’s official headquarters. While ejector systems had been produced at the Tangen site since the early years, ownership of the incinerator production had previously been managed by companies such as Saxlund and Kværner.

This strategic acquisition marked an important milestone in TeamTec’s history, strengthening its presence in Norway and laying the foundation for future growth. Shortly after, in 1998, TeamTec established its own in-house incinerator production, enabling greater control over technology, quality, and innovation within marine waste management solutions.

2012 - Acquisition: TeamTec Joins IMS Group | TeamTec

In 2012, TeamTec was acquired by the IMS Group, becoming part of a global industrial network. Since then, TeamTec has been closely connected with several sister companies within the group, including IMS Technologies, IMS Maskinering, Baggerød, Navint, Pocal, Schoenrock, and JOWA.

As part of the IMS Group, TeamTec benefits from strong industrial collaboration and shared expertise across companies. The group’s companies are frequently represented together as co-exhibitors at international trade fairs and exhibitions around the world, strengthening their global presence and industry network.

2015 - Ballast Water Management Systems (BWMS) Introduced | TeamTec

In 2012, TeamTec entered the Ballast Water Management Systems (BWMS) market through a cooperation agreement with Evonik for the development of the Avitalis BWMS.

Although the agreement with Evonik ended in 2017 due to challenges related to chemical stability in the treatment process, the collaboration provided valuable experience and technical insight.

Building on this foundation, TeamTec has continued to develop and refine its ballast water treatment technology, maintaining a strong position in the global BWMS market.

2017–2020 - TeamTec Expands BWMS Portfolio with Filter-Free Technology | TeamTec

In 2017, TeamTec acquired parts of the business from Oceansaver AS. As part of this transaction, the TeamTec Oceansaver BWMS was included in TeamTec’s portfolio of ballast water management systems (BWMS).

In 2018, TeamTec entered into a new cooperation agreement with the Japanese company Kurita, related to the development and delivery of the Kurita BWMS.

In 2020, TeamTec took over the BWMS technology from Kurita. The system was later further developed and rebranded as the well-known TeamTec Senza BWMS, a filter-free ballast water treatment system designed for efficient and environmentally friendly purification of ballast water.

2024 – Launch of Logi: Next-Generation Marine Incinerator | TeamTec

In 2024, TeamTec launched Logi, a next-generation marine incinerator designed to meet the evolving demands of modern shipping. As part of the innovative Logi series, this new solution strengthens TeamTec’s portfolio of advanced waste management systems for the maritime industry.

Engineered for improved efficiency, reliability, and environmental performance, Logi represents a forward-thinking approach to marine incineration. The system is developed to help shipowners meet stricter environmental regulations while ensuring safe and cost-effective onboard waste handling.

2026 – Compact Ballast Water Management System for Small Vessels | TeamTec

In 2026, TeamTec expanded its Senza series with a new compact ballast water management system (BWMS) designed specifically for small vessels. The solution builds on TeamTec’s proven filter-free technology, offering reliable performance with low operational expenditure (OPEX).

This compact BWMS enables shipowners to meet international ballast water treatment regulations while optimizing space, efficiency, and lifecycle costs. It reinforces TeamTec’s commitment to delivering innovative, environmentally friendly solutions for the global maritime industry.
