Lake Shore Systems Joins Trident Maritime Systems


December 28, 2021 Lake Shore Systems, Inc. is pleased to announce its integration into Trident Maritime Systems.  Lake Shore, a leading designer and manufacturer of heavy equipment for the maritime and mining industries since 1858, has worked side by side with Trident for decades.  Trident and Lake Shore will join forces to provide a comprehensive network of integrated services that will better serve their customers worldwide. Together, the companies will continue to provide the exceptional service and high-quality products that customers have come to expect.

Lake Shore began business operations as Lake Superior Foundry Company in Marquette, Michigan on July 14, 1858. The company has changed ownership over the years, but has maintained its primary manufacturing and engineering facilities in the U.P. for over 160 years.  The current primary locations include Kingsford, Iron River, and Ontonagon, MI and Rhinelander, WI.

While the company has adapted to changing markets over time, there has consistently been a focus on maritime and mining equipment.  In the early days, Lake Shore made equipment for iron ore mines and Great Lakes freighters.  In 1910, the company became Lake Shore Engine Works. In 1938, Service & Supply Company of Iron Mountain merged with Lake Shore Engine Works and the company became known as Lake Shore Engineering Company.  Wayne Oldenburg bought the company in 1987, when it became part of Oldenburg Group Incorporated.  J.F. Lehman & Company acquired the company in 2016, returning it to the Lake Shore name.  J.F. Lehman & Company also owns Trident Maritime Systems.

Beginning January 1, 2022, the company will rebrand as Trident Maritime Systems – Heavy Equipment Group.  New signs will be installed at each facility in early January and integration efforts will continue into 2022.  All Lake Shore facilities will remain open, all employees will be retained, and the company will continue to hire talented people who want to make a difference.  The newly-named Trident Maritime Systems - Heavy Equipment Group will continue to operate as a designer and manufacturer of safe, reliable, innovative equipment and solutions to its global maritime and mining customers.  Lake Shore’s products are found on every surface ship in the US Navy and include shipboard cranes, anchor handling systems, elevators, ramps, and doors, to name a few.  The company’s Cannon Mining product line includes drill jumbos, roof bolters, ANFO rigs, scalers, and utility trucks for the underground hard rock mining industry.  The company employs approximately 500 people, primarily in the Upper Peninsula of Michigan and Northern Wisconsin.

Lake Shore’s current President and CEO, Jessica Frost, credits their outstanding people, past and present, with the success of the company.  “This is a tremendous group of people who care about our work and our customers, and it shows.  As we look forward to the new year, we are excited to join the Trident family and look forward to many more successful years.”

Containerized Battery Energy Storage System Delivered to A.P. Moller Maersk (Denmark)

November 13, 2019 Just a few months ago, the first Containerized Battery Energy Storage System (CBESS) went into service onboard STENA JUTLANDICA, a ferry which operates between Gothenburg, Sweden and Frederikshavn, Denmark. The battery storage was supplied as a turnkey project by Trident Maritime Systems. As a first step the system will be switching to battery power for bow thrusters and maneuvering. It has a capacity of 1 MWh, which is intended to be extended to 50 MWh to provide full battery power in the final step.

Another industry breakthrough can be reported with the delivery of CBESS600, a fully integrated containerized battery energy storage system recently supplied to the global integrator of container logistics, A.P. Moller - Maersk (Denmark). The containerized 600 kWh marine battery storage system will be installed onboard Maersk Cape Town in December 2019 and aims to improve the vessels’ performance and reliability while reducing CO2 emissions.

The CBESS solution has been developed and manufactured by Trident Maritime Systems. All required components are fully integrated in a reinforced standard 40” container allowing a retrofit on all kinds of container vessels.

The battery energy system trial is part of Maersk’s significant investment in efficiency measures.

Trident Maritime Systems has been awarded with the turnkey contract because of its ability to fully integrate the batteries, transformer, filters and converters as well as the temperature control in a standard 40” container, supplying these features onboard the vessel and carrying-out all required modifications. “Maersk is pleased with the performance of Trident Maritime Systems in supporting us with the engineering and supply of the high-quality battery container. We are looking forward to operation of the marine battery next year to evaluate its effect in reducing the fuel consumption of our non-propulsion electrical systems,” explains Ole Graa Jakobsen, Maersk’s Head of Fleet Technology.

Electrical power systems for marine vessels have existed for more than 100 years, and history has shown a high level of research and innovation, to bring the early applications of shipboard electricity of the 1880s to modern power systems. Vessels today often consist of an ever-increasing electrical load demanding increased fuel optimization, reduction of emissions, increased safety, and performance and operational flexibility.

In normal operating conditions, one or more energy sources (i.e. waste heat, diesel generator, HVSC) are connected to the main switchboard (MSB) of the vessel. At sea, the CBESS will share the load with the diesel generators or waste heat recovery plant. If all energy sources are disconnected from the MSB, the CBESS will take all loads and prevent a blackout situation. For this purpose, the CBESS600 can deliver a maximum of 1’800 kVA for a limited time period (UPS mode). This will give sufficient time for the operator to start-up a GenSet again.

Safety is of great importance when developing and manufacturing a CBESS system. All equipment used is type approved for maritime purpose. Additionally, a HAZID workshop was organized to elaborate on all possible safety, compliance and environmental issues. The intensive collaboration with Maersk, Trident Maritime Systems and the classification society (ABS) has been key for this project.

Technical Data:
  • Total System Energy          610 kWh
  • Maximum Voltage              900 VDC
  • Voltage Drive Output         440 VAC

January 25, 2019 As ship owners all over the world rush to install scrubbers in time for the 2020 Sulphur Cap, Baltec Marine is pleased to announce completion of the world’s largest turnkey scrubber retrofit of two hybrid systems. Based on the success of these two pilot projects, the company has been contracted to oversee 18 additional Ultra Large Container Ships in 2019.

“The ship owner turned to us from the start because they did not want to handle the work in-house, and they knew our team had the experience necessary to drive a project of this size,” says Ronnie Petersson, Baltec Marine’s Executive Director.

The installation work took place while the 16000 TEU vessels were in dry dock in Shenzhen, China, starting in October of 2018. “Given the quick turnaround required, the fact that we could manage to contract the shipyard directly was a big advantage,” adds Managing Director Andrzej Dzienski.

The massive undertaking consisted of two pilot projects in which Baltec oversaw every step, from engineering to the commissioning of two different hybrid scrubber systems. The company plans to replicate their success when they install 18 more systems back-to-back for the same client in 2019.

About Baltec’s Turnkey Scrubber Installation Expertise

Baltec Marine currently has the leading edge in scrubber installation, having been chosen by the Carnival Corporation to install scrubbers on its passenger vessels as early as January, 2014. Since then Baltec has managed turnkey installations for the majority of the world’s cruise and commercial shipping lines – for a total of more than 130 scrubbers on more than 50 vessels.

The company works with the leading manufacturers of exhaust gas cleaning systems to offer complete turnkey installation packages. Together with its parent company, Trident Maritime Systems, Baltec Marine can offer global reach. Baltec Marine is ISO 9001-certified and works in compliance with all marine and offshore regulatory bodies and conventions.

Let’s talk about how Baltec Marine can help you solve your shipbuilding and outfitting challenges.
