Letter of Intent (LOI) to jointly develop a retrofittable air layer drag reduction system

Royal Roos and Marine Bubble Flow have agreed to enter into a collaboration to develop, test, market and deploy MBF’s retrofittable air layer drag reduction system (ALDS). This globally patented system relies on a new combination of fluid dynamics and air-based fluidics technology to allow controlled injection and release of air bubbles into the boundary layer around vessels.

The expectation is that the fully developed MBF system will materially reduce the drag, by up to 30%, and therefore the fuel consumption and emissions of vessels, by up to 15%.

This collaboration brings together Royal Roos’ systems integration, advance manufacturing (3D-printing) and maritime services capabilities with MBF’s innovative fluid dynamic and fluidics know-how, to create an industry leading drag reduction system that will improve the profitability of shipping and reduce the environmental footprint of the maritime industry.

DNV_GL approved bolted sea fastening for W2W-system reducing mobilization time

For one of our long term customers providing Walk to Work systems (W2W) for the renewables and offshore industry Royal Roos provided a bolted sea fastening design that strongly reduced the time to mobilize a W2W-system on an offshore vessel. The clips to sea fasten the structure are normally welded which could take 1 - 3 days, especially when allowing for a cooling down period of 24 or 48 hours for NDT purposes. Furthermore, it requires flame cutting and afterwards grinding to remove the welded clips. The bolted sea fastening using "bricks" takes just 2 - 3 hours without the need for NDT. Removal is just as easy by unbolting the "bricks".

Our design (the "Brick-design") consists of a welded and machined countersunk bottom plate welded to the supporting structure (deck or pedestal) to keep the W2W-system safely in place using shims. The "bricks" are then bolted down on top and pre-tensioned.

The "Brick-design" comes as a complete package: engineering and fabrication of the "Brick-design" sea fastening plate.

In case you require other innovative sea fastening solutions do not hesitate to contact Royal Roos BV.

Top support for sea fastening of lift

To support a lift giving access to a W2W system of Ampelmann Royal Roos was asked to perform structural engineering calculations and drawing works. The lifts is connected to the warehouse on an Offshore Supply Vessel. FEM calculations were done to verify the structural strength of the support and ship's structure under various loading conditions (LR CLAME). This included amongst others, weld and other checks according EUROCODE 3. Provision of basic engineering drawings was part of the scope.

Royal Roos expands activities with 3D printing in cooperation with CEAD B.V.

Royal Roos has entered into a cooperation with 3D printer manufacturer CEAD B.V. to develop and build an industrial size CFAM 3D printer.

Royal Roos has founded a new company for its 3D printing activities, Royal3D B.V.. Royal Roos contributes to the development of the printer by purchasing the prototype, engineering of the printer frame and table and furthermore develops specific 3D printable applications for the maritime industry. The machine has been under development by CEAD since September 2017 and expectations are that it will be ready mid-2018. The machine has a granulate extruder with an hourly extrusion rate of at least 15 kg per hour and prints objects with a build volume of 4 x 2 x 1.5 metres accurately and fast.

Continuous Fibre Additive Manufacturing (CFAM) technology adds a continuous carbon or glass fibre to the granulate adding considerable strength to the material. Fibre can be added to thermoplastics like PP, PET, ABS, PLA and PEEK. An internal heating mechanism prevents warpage and shrinkage during printing and allows the print to cool down in a controlled way.

Owner of Royal Roos, Fulko Roos, has acknowledged 3D printing opportunities for the maritime industry for quite some time already. However, fast and accurate 3D printing of larger composite parts with sufficient strength in the material was not yet available. Therefore, the timing for cooperation with CEAD could not have been better.

CEAD is founded by two of the four original founders of Leapfrog, Lucas Janssen and Maarten Logtenberg. Leapfrog is specialized in 3D desktop printers. CEAD has been founded in 2014 and focuses merely on the industrial market.

Royal3D has three main pillars, the first being maritime products suitable to be manufactured in carbon reinforced plastics. This consists of research into and testing of the specific material requirements to make 3D printed parts suitable for marine use, together with research institutes, companies focusing on R&D and Classification Societies. Secondly Royal3D can print (fibre) reinforced plastics upon request for clients. And ultimately Royal3D offers consultancy services to guide companies wanting to start with or transfer to fibre reinforced plastic production, varying from placing printer(s), training employees, set up workshop and IT infrastructure and finally supplying machines and storage options for print consumables, etc..

Feasibility study for retrofit BWTS on Ultra Large Container Vessel

Recently UniBallast carried out a feasibility study for the installation of an UV system to treat ballastwater on an ULCV. Scanning and inspection was done in the Middle East, while modelling, basic engineering and reporting was done in our office in the Netherlands using AVEVA E-3D software. Typical lead time for a feasibility study including 3D scanning and engineering is 2-3 weeks. If the basic design package has been approved by Client and Class a detailed engineering package will be made.
