What DEKC Maritime does

DEKC Maritime is a Dutch maritime engineering company headquartered in Groningen, Netherlands, founded in 1980 and operating as a privately held firm with approximately 45 specialists in naval architecture, structural design, mechanical engineering, and detail engineering. The company delivers concept design, basic design, and detail engineering for new-build vessels, plus operational support across a vessel's lifecycle including modifications, mobilizations, refits, and project-specific engineering solutions. Its core technology stack centers on 3D marine engineering using Cadmatic hull/outfitting software, NAPA for hull shape generation, Ansys/Aqwa for seakeeping analysis, CFD for resistance and propulsion optimization, and FEM calculations for structural analysis. A distinctive proprietary capability is the company's adapted seismic-based methodology for jack-up vessel resonance prediction, which received formal approval from classification society DNV.

DEKC generates revenue through project-based engineering and design contracts on a professional services basis. Pricing is bespoke and scope-dependent, with no public pricing; revenue is earned through one-time project fees for specific deliverables such as stability booklets, construction plans, workshop drawings, production information, and FEM calculations. The go-to-market motion is consultative enterprise B2B sales directly to ship owners, shipyards, and offshore operators, with projects originating from client inquiries or referrals within the Northern Netherlands maritime cluster. The company maintains distribution partnerships for specific markets — notably Green Shipping Line as the commercial interface for Jones Act compliant designs in the US offshore wind market.

The company's primary customer segments are offshore wind installation/maintenance operators, dredging companies, general ship owners and shipping companies, and (emerging) US offshore wind developers. Named enterprise clients include Wagenborg Shipping, Van Oord, Acta Marine, Jumbo Maritime & Offshore, Eidsvaag, Amasus, Carnival Maritime, and Neptune Marine, with project work spanning offshore wind installation vessels, trailing suction hopper dredgers, general cargo vessels, cruise conversions, and architectural applications. In November 2024, ownership transitioned from Nimbus hands-on investors to Theodoor de Jonge (managing director) and Ferus Smit, aligning the company with Northern Netherlands shipbuilding industry insiders.

Partnerships

Seven partnerships are on record, tiered core and minor.

• Green Shipping LinecoreGTM or Marketing Partner · 9 June 2021DEKC signed a Teaming Agreement with US-based Green Shipping Line (GSL) to pursue Jones Act compliant offshore wind vessel solutions in the United States. DEKC provides vessel design and engineering expertise for GSL's fleet, including the Eleanor model (364-ft multipurpose Jones Act feeder vessel). GSL handles US regulatory compliance, shipyard relationships (Moran Iron Works in Michigan), vessel operations (Keystone Shipping), and commercial partnerships. The Eleanor model received Approval in Principle from the American Bureau of Shipping and is designed to transport all components of a wind tower from port to installation sites in a two-day cycle.
• Global Drone InspectioncoreStrategic or Co-development PartnerDEKC and Global Drone Inspection (GDI) co-developed a drone pilot training simulator featuring 3D models of vessels and industrial assets. The partnership leveraged DEKC's 3D modelling capabilities and GDI's drone inspection expertise. The simulator allows pilots to train flight and inspection skills in a safe environment. Licenses for the simulator are sold in three tiers: Basic Training, Advanced Training, and Custom Scenarios. The software is available for free download with a free play flight option, while custom scenario licenses are sold commercially. The partnership addresses the challenge of training skilled drone inspection pilots without requiring physical assets.
• Groot Ship DesignminorStrategic or Co-development PartnerDEKC Maritime and Groot Ship Design are sister companies under shared ownership (Theodoor de Jonge and Ferus Smit as of November 2024). Both companies operate autonomously and serve their respective markets — DEKC focuses on offshore wind, dredging, and operational markets while Groot Ship Design focuses on shortsea and ocean-going cargo vessels. The companies look for synergy at the interfaces of technology and organization, using each other's capacity to offer customers better and more efficient solutions.
• Van OordcoreImplementation/ SI/ Consulting PartnerDEKC worked in close cooperation with Van Oord's design team during the entire basic design and class approval phases for the ZSH series trailing suction hopper dredgers. The relationship includes extensive stability calculations, FEM structural analyses, and design/engineering/integration of critical on-board systems. DEKC also provided additional engineering support during the production process at the Keppel shipyard in Singapore. DEKC has a long history with Van Oord including the Aeolus jack-up vessel conversion and the Vox Apolonia launch.
• Eekels bvminorImplementation/ SI/ Consulting PartnerDEKC cooperated with Eekels bv on the AidaMira cruise vessel conversion project. DEKC was contracted for structural integrity, stability books, and system/electrical design support, with the electrical design work conducted in cooperation with Eekels bv. This represents a subcontracting partnership where Eekels provides electrical engineering expertise within DEKC's overall engineering package.
• TODDIS ConsortiumminorStrategic or Co-development PartnerDEKC Maritime participates as an executive partner in the TODDIS (Transferring Operational Data into Design Information for Ships) consortium. The project aims to use operational big data from ships in service to improve ship design tools, particularly for ship resistance, seakeeping, and open-top ship design. This is a research partnership with academic and industry participants focused on advancing naval architecture methodologies.
• DNVminorStrategic or Co-development PartnerDNV is a classification society with which DEKC Maritime collaborated to obtain formal approval for their adapted seismic calculation method applied to jack-up vessel resonance management. DEKC presented the methodology to DNV in Oslo, and it received formal approval. DNV represents the regulatory and classification approval process for maritime vessels, and this partnership is significant for DEKC's jack-up engineering credibility.
