Operationele ondersteuning
Operational challenges often need quick decisions backed by sound engineering.
DEKC supports vessel owners, operators and contractors with practical engineering for mobilisations, transport operations, modifications, structural issues, stability questions and other vessel-specific challenges. We respond quickly, involve the right expertise and develop solutions that work in practice.
Refits and modifications
DEKC Maritime provides engineering and production solutions for vessel refits and modifications, supporting compliance, efficiency improvements and energy transition projects.
Our expertise includes engine renewals, scrubber refits and the implementation of LNG or dual-fuel solutions. We can support any individual step in the process, through to the complete refit of your vessel.
Our extensive expertise in 3D engineering and laser scanning enables us to deliver detailed engineering packages, including piping, outfitting and installation procedures. A modular approach allows for prefabrication and efficient installation, significantly reducing retrofit time on board.
Seafastening and grillage
We combine our hands-on experience with high-end analysis tools to design grillages that are very lightweight, as well as safe and practical in use.
This means there is more deadweight left for payload, there are fewer costs involved in construction, and turnaround times are short.
To achieve this, we design grillages to make use of the existing strength in the ship, with direct input from our in-house motion analyses. We can also calculate fatigue and perform stiffness checks on the grillage and ship together, to avoid problems with vortex-induced vibrations.
Seakeeping and workability
Seakeeping analyses are performed to calculate and optimise the workability of offshore operations such as lifting and grouting.
These analyses can also provide input for the design of sea fastenings, resulting in a lighter and more balanced structure.
At DEKC, motion analyses can be performed based on both 2D and 3D methods, and in the frequency and time domain, depending on client and surveyor requirements.
Regulatory support
DEKC has experience dealing with all major classification societies and many flag states.
This means we can be of assistance with all regulatory questions, such as reflagging or reclassifying vessels.
We can also contribute to discussions with governing bodies regarding the interpretation of, or exemptions from, specific rules.
Tools and mobilisations
We offer design and engineering support for mobilisations, including stability and ship motion analyses, structural and mechanical modification drawings, and management of class approval.
In collaboration with our trusted partners, we deliver the steel building package and can manage the mobilisation itself.
Besides the modifications to the vessel itself, we also provide design and engineering services for the custom tools necessary to do the job, such as fall pipes, support frames, and equipment bays.
Proof on real vessels
Aeolus
De Aeolus is het vlaggenschip onder de hefeilanden van Van Oord en vormt de hoeksteen van veel van haar bouwprojecten voor offshore windparken. Het schip onderging een ingrijpende modernisering om concurrerend te blijven op de markt voor offshore windenergie. De belangrijkste aanpassing betrof de vervanging van de oorspronkelijke kraan met een capaciteit van 900 ton door een kraan van 1600 ton, de grootste in zijn klasse.
Ondersteunende structurele verbeteringen omvatten het toevoegen van sponsons en versterkte dekken aan de romp, wat zowel de sterkte van het schip als de laadcapaciteit verbeterde. De spudcans van de hefpoten werden vergroot om hogere belastingen aan te kunnen. Aanvullende verbeteringen omvatten een nieuw helikopterdek en een extra accommodatie-eenheid om de toegankelijkheid te verbeteren.
DEKC Maritime leverde uitgebreide ondersteuning tijdens de hele ombouw, beginnend met de eerste haalbaarheidsstudies en gevolgd door gedetailleerde structurele, stabiliteits- en capaciteitsanalyses met behulp van FEM- en CFD-methodologieën. De diensten strekten zich uit tot de goedkeuring door de classificatiebureau en omvatten de volledige detailengineering en de productie van de rompbekleding.
