Mammoet and Port of Argentia advance floating dry dock project in Canada.

Mammoet and Port of Argentia advance floating dry dock project in Canada. Published: October 28, 2026 Reading time: 2 min. Mammoet Canada Eastern Ltd., Port of Argentia Inc. and Argentia Capital Inc. (ACI) have signed a memorandum of understanding to advance plans for a floating dry dock and marine repair facility at Port of Argentia in Newfoundland and Labrador, Canada. The proposed development would combine Mammoet's expertise in engineered heavy lifting, transport and marine operations with technology from its subsidiary, Tugdock Submersible Platforms Ltd., and the port's marine infrastructure and industrial development capabilities. The project would be built around Tugdock's Submersible Platform (TSP), a modular floating dry dock system designed to accommodate various vessel types and industrial applications. Its scalable configuration is intended to offer an alternative to conventional dry-docking infrastructure and allow the facility to adapt to changing market demand. "This partnership represents an exciting opportunity to build on Mammoet's established presence at Argentia and introduce advanced, scalable marine technology to the Canadian market," said Jeremy Asher, managing director at Mammoet. He said the combination of Mammoet's technical expertise, Tugdock's adaptable platform and the port's infrastructure could support the development of a competitive marine repair and servicing operation. Port of Argentia offers deep water, an ice-free harbor, extensive industrial land and existing graving dock infrastructure. Its separation from residential areas is also expected to support year-round marine industrial operations, including around-the-clock work. The project could draw on the region's skilled workforce, which has experience in marine operations, industrial activity and heavy construction. Mammoet already operates at the port, including at the Cenovus Graving Dock site, and has participated in the port's offshore wind marshalling projects. "We have developed a strong working relationship with Mammoet through its operations at the Port, including its presence at the Cenovus Graving Dock site and its role in the Port's offshore wind marshalling projects," said Scott Penney, CEO of Port of Argentia. Penney said the combination of the port's marine infrastructure, Mammoet's international expertise and the proposed technology could expand Argentia's marine industrial capabilities and support emerging opportunities across Canada's marine sector. The planned facility is intended to serve several markets, including commercial vessel operators, the Canadian Coast Guard, the Royal Canadian Navy, offshore oil and gas operators, and the growing offshore wind industry. ACI CEO Carl Sheppard said Port of Argentia could play a broader role in Canada's industrial development, beyond hosting individual projects. He described the port as a potential national marine and industrial hub supporting long-term trade, economic security, critical minerals, defence and industrial development. Sheppard also identified the former Cenovus Graving Dock site as a valuable marine industrial asset and said the memorandum creates an opportunity to assess new uses for the site with partners bringing established technology and expertise. Under the agreement, the three organizations will advance plans for a scalable, multi-client facility intended to strengthen Newfoundland and Labrador's marine supply chain, create opportunities for local businesses and skilled trades, and expand the province's marine industrial capacity. In the coming months, the partners intend to launch a formal Expression of Interest process to identify a globally recognized marine industrial operator with the expertise and resources to run the proposed facility and help develop marine services at Port of Argentia.

Mammoet, Port of Argentia plan floating dry dock to expand Canadian ship repair capacity.

Mammoet, Port of Argentia plan floating dry dock to expand Canadian ship repair capacity. 23 October 2026 Estimated reading time: 5 minutes ARGENTIA, Canada, October 23, 2026 - Mammoet Canada Eastern Ltd., Port of Argentia Inc. and Argentia Capital Inc. (ACI) have signed a memorandum of understanding to develop a floating dry dock and marine repair facility in Newfoundland and Labrador, targeting growing demand for vessel maintenance, offshore services and marine industrial capacity in Atlantic Canada. The proposed development would combine Mammoet's heavy lifting and marine engineering capabilities with modular floating dock technology from its subsidiary, Tugdock Submersible Platforms Ltd., and existing infrastructure at the Port of Argentia. The agreement establishes a framework for further development rather than a final investment commitment. The partners plan to seek an experienced marine industrial operator through a formal Expression of Interest process in the coming months. Modular floating dock technology at centre of project. The proposed facility would use Tugdock's Submersible Platform (TSP), a modular floating system designed to support vessel docking, marine maintenance and industrial operations. Unlike conventional fixed dry docks, the TSP uses a scalable configuration that can be adapted to different vessel sizes and operating requirements. The technology could allow the partners to establish additional docking capacity without relying entirely on the construction of permanent dock structures. For shipowners, access to suitable repair facilities can influence maintenance schedules, vessel positioning and operational downtime. Flexible docking infrastructure could provide another option for operators seeking maintenance services in Atlantic Canada. The project would combine the floating platform system with existing port infrastructure, including the former Cenovus Graving Dock site. "By combining our technical expertise and Tugdock's adaptable platform with the Port's strategic infrastructure, we see significant potential to develop a competitive marine repair and servicing operation," said Jeremy Asher, Managing Director at Mammoet. The companies have not disclosed the proposed facility's investment value, lifting capacity, vessel size limits or expected commissioning date. Argentia infrastructure supports year round operations. Located in Newfoundland and Labrador, the Port of Argentia offers a deep water, ice free harbour, industrial land and existing marine infrastructure. Its separation from residential areas also provides conditions suitable for marine industrial activities operating around the clock. These characteristics are relevant to ship repair operations, where vessel movements, heavy lifting, fabrication and maintenance work can require extended operating periods. The port also has access to a regional workforce experienced in marine construction, offshore energy and heavy industrial projects. Mammoet already maintains an operational relationship with Argentia through activities at the Cenovus Graving Dock site and participation in offshore wind marshalling projects. According to Scott Penney, CEO of Port of Argentia, that relationship provides an established basis for evaluating additional marine services. "We have developed a strong working relationship with Mammoet through its operations at the Port, including its presence at the Cenovus Graving Dock site and its role in the Port's offshore wind marshalling projects," Penney said. The proposed facility would build on those existing activities while introducing a broader range of vessel servicing capabilities. Commercial shipping, defence and offshore energy targeted. The partners envisage a facility serving several marine market segments rather than depending on a single customer or industrial sector. Potential customers include commercial shipping operators, the Canadian Coast Guard, the Royal Canadian Navy, offshore oil and gas companies and developers involved in offshore wind projects. Each sector has different maintenance requirements, ranging from routine vessel servicing to more specialised marine engineering work. For commercial operators, regional repair capacity could reduce the need to reposition vessels to more distant facilities, depending on vessel dimensions, service requirements and available dock capacity. Government and defence vessels could also represent potential customers, although no service contracts or procurement commitments have been announced. The offshore energy sector presents another potential market. Marine construction vessels, support craft and other specialised equipment require maintenance facilities capable of handling demanding operational schedules. The partners have not specified which vessel categories would be accommodated initially or whether the proposed facility would include dedicated fabrication and repair workshops. Partners seek marine industrial operator. Argentia Capital views the project as part of a broader effort to strengthen the port's industrial role in Canadian maritime activities. Carl Sheppard, CEO of Argentia Capital, said the port should be considered a strategic industrial location supporting trade, defence, critical minerals and long term economic development. "The former Cenovus Graving Dock site is a valuable marine industrial asset," Sheppard said. He added that the agreement provides an opportunity to examine additional marine industrial activities with partners bringing established technology and operational expertise. The next development stage will focus on identifying a marine industrial operator capable of managing the proposed facility and developing its customer base. The partners intend to launch a formal Expression of Interest process in the coming months, seeking a globally recognised operator with the technical experience and commercial capacity required for the project. The selection process will be an important step in defining the facility's operating model, service offering and potential market commitments.

Mammoet COO Jan Kleijn to leave after 30 years as leadership transition begins.

Mammoet COO Jan Kleijn to leave after 30 years as leadership transition begins. 23 September 2026 Estimated reading time: 4 minutes Mammoet Chief Operating Officer Jan Kleijn will leave the heavy lifting and transport specialist on February 1, 2027, ending a 30 year career with the company that included 15 years in senior leadership roles as CEO and COO. The departure will trigger a transition of responsibilities within Mammoet's Executive Board of Management as the company prepares a new generation of leaders to take on senior responsibilities. Kleijn joined Mammoet in operational and logistics roles before progressing through the organisation and eventually becoming the company's first employee to rise to the position of CEO. He later became COO, a position he has held since 2017. His career has covered a period in which Mammoet expanded its international heavy transport and lifting operations across energy, infrastructure, industrial and offshore markets. From operations to the executive board. Kleijn's progression from day to day operations into the executive suite gave him experience across both the practical and commercial sides of heavy transport. That distinction matters in a sector where decisions made in an office can ultimately determine how hundreds or thousands of tonnes of equipment are moved safely through ports, industrial sites and infrastructure corridors. Heavy lifting companies operate at the intersection of engineering, transport, project management and risk. Large projects can require years of preparation, while equipment fleets and specialist personnel often have to be committed well before cargo begins moving. Kleijn spent about half of his three decades at Mammoet in leadership positions, including both CEO and COO. Since becoming COO in 2017, his responsibilities have included supporting the company's global operations as Mammoet continued developing its position across heavy lifting and specialised transport. The company said his tenure helped leave the business financially strong, geographically diversified and positioned to serve major projects worldwide. Focus on people and succession. Mammoet also highlighted Kleijn's role in developing employees and strengthening working cultures across the organisation. Talent development can be particularly important in heavy transport and lifting because much of the industry's expertise is built through years of practical experience. Operators, engineers, project managers and supervisors routinely deal with loads and lifting configurations where there is little room for error. Passing that knowledge between generations can therefore be as important as investing in new cranes, transporters or engineering technology. Kleijn's decision to transfer responsibilities to a younger generation of leaders reflects that focus on succession, according to the company. Mammoet CEO Joost Goderie said long term thinking had been central to Kleijn's approach to executive management. "Jan has always believed that executive decisions must be made with the long term in mind, a principle central to Mammoet's success," Goderie said. "True to that belief, he is confident the time is right to pass the baton to the next generation of leadership, and that Mammoet is well positioned for what lies ahead." Transition begins ahead of February departure. Mammoet's Executive Board of Management will use the period before February 1 to manage the transfer of Kleijn's responsibilities. The company said the process would focus on continuity and ensuring an effective transition. No replacement or revised executive structure was identified in the announcement. For customers, the practical issue will be continuity across Mammoet's global project portfolio. The company provides engineered heavy lifting and transport services for major energy, infrastructure, offshore and industrial developments, where planning and execution can extend across several years. "Every day, our people deliver extraordinary solutions that support critical energy, infrastructure, industrial and offshore projects around the world," Goderie said. "As we continue to serve our customers and expand into new industries, we do so on the strong foundation that leaders like Jan have helped to build." Kleijn will remain with Mammoet during the transition period before formally leaving the company on February 1, 2027, bringing his 30 year career with the heavy lifting and transport group to an end.
