This page shows a selection of Hoek Naval Engineering's actual and past projects

September 2012 - December 2012
In close cooperation with the shipyard, Hoek Naval Engineering provided basic engineering and detailed engineering for this challenging project. Challenging in every way; continuously changing design criteria and a short delivery time created those challenges. However with construction near completion in early January 2013 this project may be considered as a succes, even though the trajectory pushed the cooperation between all parties to the limit.
More information expected upon delivery

May 2012 - Present
This project started for Hoek Naval Engineering with the pre-design of a 15×8 m versatile pushertug, derived from the HNE VersaWorker series, for the African inland and coastal waters.
After the pre-design phase the client altered the design criteria for draft, performance and overall dimensions, resulting in various challenges for Hoek Naval Engineering.
Having the detailed engineering and production information near comletion, Hoek Naval Engineering managed to fullfill the client requirements and is able to provide the shipyard with a ready for building information package. Hoek Naval Engineering will follow the production closely as building inspections are included in their order.
More information expected upon completion.

April 2012 - May 2012
As the third party basic engineering for several sea-going barges resulted in significant comments from the class society, this client awarded Hoek Naval Engineering with order to update the construction plans and arrangements of seven barges. Due to a lack of time only the most urgent issues were processed, allowing the client to meet her building schedules without constructional errors.
The works included 2D drawings, WBM calculations as well as Finite Elements Method Analyses.

March 2012 - July 2012
After succesful previous projects, this client awarded Hoek Naval Engineering again with an engineering order for a 135 m river cruise ship. The challenges for this project were the continuous changes without a change of delivery time. Hoek Naval Engineering managed to deliver the full engineering package including updated hull shape and production information within the expected delivery time.

February 2012 - April 2012
Due to engineering difficulties this client contacted Hoek Naval Engineering to take over project management. At the time Hoek Naval Engineering started with the project management the project was already behind 15 weeks, making the contractual penalty a real threat for the client. Due to the continuous efforts, Hoek Naval Engineering managed to get the project back on track in only four weeks!

January 2012 - February 2012
The latest addition to the HNE VERSAWORKER series is the HNE VERSAWORKER 3012. This heavy duty VERSAWORKER is designed for all possible offshore tasks, from anchor handling and diving support to windmill park construction support and hotel operations. The modern and well-designed accommodation allows for a total of 16 persons! With large tankcapacities and a variety of green solutions as well as dynamic positioning, this ship is bound to be one of a kind, creating a new class and standard in the market!

January 2012
The HNE VersaWorker 1909 is designed to be a worthy member of the HNE VersaWorker family. In the wake of the 2511 this well-equiped VersaWorker 1909 promises to be a succesfull addition to the VersaWorker series.
The large clear deck area as well as heavy duty bow and stern roller allows for anchor handling and diving support. The two winches in waterfall position as well as the double deck cranes make this design versatile and complete. Together with outstanding performances a new standard is set for this class!

December 2011 - January 2012
This small but versatile workboat of the HNE VersaWorker series has been designed to gain maximum performances within very small dimensions; a length just over 15 m and a width just over 6 m.
Besides pushing and towing services and buoy handling this ship has sufficient tank capacities for uninterrupted sailing for more than a week.
The small but modern accommodation and wheelhouse provide a good living and working environment for the crew.

December 2011
Hoek Naval Engineering was awarded with the order for a mooring calculation for a floating wellness center across the border. As specific requirements were set with regards to anchor positions and non-disrupture of the seabed, the calculation resulted in the development of a new versatile mooring system for shallow waters with tidal decay.
As usual Hoek Naval Engineering managed to work on a tight budget and schedule to fullfill all client requirements.

September 2011 - December 2011
Although the order for the preliminary basic design came with the demand for a very short delivery time, Hoek Naval Engineering managed to fullfill the client's requirements.
The preliminary design is followed by the basic and detailed engineering.
This small, but versatile tug combines high performances (16 t BollardPull and a speed of 9 kts) with low operational costs and can be deployed for harbour operations as well as river and coastal operations.
The modern accommodation spaces will be suitable for a total of 4 people (1+1+2) and meets the highest standards.

July 2011 - August 2011
This project started for Hoek Naval Engineering shortly before the company holidays. As delivery time suddenly had to be shortened, work continued during the holidays.
Production information was delivered in time, making sure their client's delivery schedule was not compromised.
The integration of the required extensions, helideck support structure and elevator came with some challenges, however Hoek Naval Engineering proved to be worth counting on.
The accommodation module is momentarily under construction and will be placed onboard an offshore transformer platform.
The module provides modern living space for more than 35 people.
More updates to be expected upon completion of construction.

March 2011 - September 2011
Hoek Naval Engineering was awarded the detailed engineering of a 110 m river cruiseship. Upon completion of the first sections the basic engineering had to be updated due to design changes.
Updating the basic engineering allowed Hoek Naval Engineering to realize more bending stiffness and torsional stiffness in the construction. Also bending moments were reduced; all to improve passenger comfort levels significantly.
With construction well under way, this ship is expected to have her maiden voyage by end of March 2012.

December 2010-March-2011 
Hoek Naval Engineering's  client has awarded them with the design and engineering of a MultiWorker. This versatile workboat, a derivative of the HNE VersaWorker series, will be equipped with heavy duty anchor handling and towing winches, total pulling force 120 t. Both bow and sternrollers will be suitable to handle heavy anchors and tidal generators and will withstand severe forces. With an outreach of 20.00 m and a high capacity, the deck cranes are also to be taken seriously.
The required delivery time really pushed Hoek Naval Engineering to the limits. This MultiWorker is one of a kind and brings a new standard to the market with a bollard pull exceeding 24 t and a speed well above 10 kts!
The superb performance and handling is due to the well-designed hullform.

November 2010
For a major anchors & chaincables testing facility, Hoek Naval Engineering prepared a drawing package of a tensile strenght tester. This tensile strength tester is developed for pulling forces of up to 750 t.
The job comprised detailed drawings of the steel construction and FEM analyses of the underneath foundation. Based on this information package a new concrete foundation will be laid in their client's production facility.

October 2010 - June 2011
Enforcing her client's engineering and building team, Hoek Naval Engineering has been awarded the project management for one of their client's new-build inland passenger vessels.
Combining the ship-owner's demands, with the yard's possibilities, this ship is bound to be one of a kind.
An ambitious planning and innovative outfitting make this a very challenging job!

September / October 2010
Hoek Naval Engineering has been awarded the detail engineering of an aft ship section for one of her client's newbuild projects.
In close cooperation with the client and her subcontractors Hoek Naval Engineering prepared a digital prototype of the aftship, complete with double flexible mounted main propulsion system.
The focus lies on a flexible model which allows for easy conversions and finetuning prior to production.

September 2010
An optimization of the existing body plan was required by Hoek Naval Engineering's client. As the vessel has a limited draught, combined with a thruster channel, optimization was required to prevent air from entering the thrust flow.
The existing bodyplan is being optimized for flow and displacement in the aft ship area.
CFD-calculations have been executed to find the optimum in the client's demands.

August / September 2010
The engineering works of this project included on-site measuring of the existing pontoons. Based on the overall measured dimensions and plate thicknesses, drawings for the elongation and assembly of the pontoons were made. Local strenght, in way of the new deckcrane was checked using FEM analyses software.
A total of 4 existing pontoons were build together with three newbuild elongation sections.
   

August 2010
Using FEM Analyses Hoek Naval Engineering checked the foundation for a retractable wheelhouse.
As class society required solid proof of the local strength, the client awarded Hoek Naval Engineering the order for executing a FEM Analyses.
In this analyses the focus lies on local combined stresses and displacement.
A detailed model of the relevant construction is being prepared and an analyses report will be filed with class.
As the vessel's construction is near completion, time and accuracy is of the essence!

July / August 2010
Hoek Naval Engineering BV has recently been awarded the main construction for a river cruise ship. With a length exceeding 130 m, longitudinal strength is one of the main focusses in this project.
Besides the light weight construction and mandatory trim of even keel, a challenge is found in reducing the 'hogging' condition of this ship.
Working closely together with the shipyard the focus is on a 'one time right' main construction.
More updates on this project soon...

July 2010
An existing heavy cargo barge was converted for specific transportation requirements. As the cargo loads and positions differed significantly from the initial design criteria, longitudinal strength became an issue.
In close cooperation with their client Hoek Naval Engineering calculated the bending moments, main frame characteristics and occuring bending stresses and shear stresses.
Besides the indicated calculations the job also included recommendations for structural improvement.

June 2010
As their client deployed one of the fleet's tugs for ploughing and seabed leveling, an A-frame had to be arranged.
Hoek Naval Engineering designed and engineered both the A-frame and the adjustments to the vessel's construction. Using Finite Element Analyses software they were able to find and eliminate concentrations of high stresses in the construction and simulate heel and trim of the vessel to optimize the construction for its intended duty.

June 2010
For transport and storage of ships with a weight up to 40 t, Hoek Naval Engineering designed and engineered a new boat cradle to be used with the client's existing cradle carrier.
As the client had specific requirements regarding safety and deflection of the construction, this cradle became a real heavy duty construction.

May 2010
For one of their client's newbuilding department, Hoek Naval Engineering has been working on a feasibility study for a newbuild offshore support vessel. This job included the technical comparison of several propulsion systems, a conceptual design and an evaluation of initial costs.

Februari 2010 - April 2010
Expanding the client's engineering team, Hoek Naval Engineering worked on the construction drawings of the aft ship of a dredger vessel.
This job included general construction plans, work-shop drawings and propulsion arrangements.

February 2010
For one of their clients Hoek Naval Engineering designed and calculated a lifting frame for lifting small ships up to 40 ton. The job included preparation of workshop drawings, selecting the construction company, the purchasing, testing and certification.

The challenge came with the specifications, stating a steel construction with a weight of max. 2 tons (metric), combined with main dimensions of 7.2×5.2 m. By changing the conventional lay-out of lifting frames, Hoek Naval Engineering was able to combine maximum strength with minimum weight.  

November 2009 - February 2010
Expanding their client's design & proposal team, Hoek Naval Engineering worked on-site on the design & proposal engineering of various new vessels.
This job included full pre-desings, complete with technical specifications, body plans, general arrangements, preliminary stability and cost price estimations.
Combining both clients resources and Hoek Naval Engineering's expertise, they managed to create some succesful designs for a shallow water tug, a multi purpose workboat and a fast river ferry.

November 2009
As the project specifications stated maximum cargo capability, minimum draught, fixed main dimensions, and bollard pull requirements, this pre-design came with challenges!
Besides the very tight planning, Hoek Naval Engineering also incorporated a built bowsection  in the hull design.
They managed to deliver a 3D hull, a preliminary General Arrangement Plan and a preliminary Tank Arrangement in only a few days. All meeting their client's requirements.
