Van Oossanen Naval Architects has developed hydrofoils and computational fluid dynamics (CFD) tools over the last decade. They have designed nearly 100 vessels and currently have 12 under construction. Their CFD analysis uses RANSE solvers with sliding grids and adaptive mesh refinement to simulate hydrofoils in foiling mode. Their development of the Hull Vane device uses CFD to study flow details, with model testing showing the Hull Vane provides forward thrust and reduces resistance by up to 25% for various vessels.

The document summarizes the design of the RAVE V foiling sailboat, including its V-shaped foils, retractable foil system, A-frame sail rig, and accessibility features. The V-foils generate lift from both submergence and a lifting surface. An A-frame rig simplifies the structure and utilizes triangular strength. The integrated systems are designed for low weight, high speeds, ease of use including for handicapped sailors, and simplifying launching and trailering. The goal is a boat that can exceed 35 knots while being user-friendly.
High Performance Catamaran Design & Optimisation with HyperWorks
This document discusses the design of a high performance C-Class catamaran being built by Team Rafale-ETS to compete in a sailing competition. It provides details on the team members and boat design, including an overview of C-Class catamarans. It then focuses on a case study using Hyperworks software to optimize the design of the hydrofoil through composite modeling and optimization to achieve the desired strength, stiffness and weight requirements. The hydrofoil design was refined through this process and other components of the boat design and analysis were also performed using Hyperworks tools.

Schmidt
The document describes a new hull design called SLICE that allows small ships to operate at high speeds in rough seas. SLICE builds on previous SWATH (Small Waterplane Area Twin Hull) designs by further reducing the waterplane area and shortening the hull length. This allows SLICE vessels to maintain high speeds in larger waves compared to conventional monohulls or catamarans. Testing of a SLICE prototype demonstrated its ability to operate at over 30 knots while producing very low wake wash, using 20-35% less power than comparable designs. The document outlines potential military and commercial applications for SLICE ships.
BMT Catamaran Development
BMT has developed new hybrid catamaran/SWATH hull designs that offer significantly improved vessel motions in rougher seas compared to conventional high-speed catamarans. These include the MODCAT semi-SWATH design and new eXtreme Semi-Swath (XSS) hull, both aimed at meeting client requirements for passenger comfort while maintaining high speeds. The XSS design in particular combines the motion benefits of SWATH hulls with catamaran speed through the use of waterplane area reduction and active ride control systems.

C7a Mooring Layouts_2020
Mooring analysis involves designing an offshore mooring system to withstand extreme environmental conditions like 100-year storms. Key factors in the mooring layout include the strength of each mooring line, seabed topography, and directions of wind, waves and currents. Common mooring patterns are distributed to balance loads and provide redundancy. Analysis calculates line tensions and vessel excursions in storms, traditionally analyzing mooring and risers separately but now integrated. The purpose is to ensure the vessel stays within acceptable distance limits under worst loads.
Offshore Support Vessels Design
An Offshore supply vessel is a multi-task vessel and has to be designed for many different purposes. This is contrary to most other ships used worldwide. In general, the geographical location where the offshore activity takes place is an important indicator of the choice of supply vessel.
Factors like weather conditions, the amount of equipment needed and the distance from the shore are important for what properties the vessel should have. The deep-water oilfield market is becoming more important as the conventional oilfield market in shallow water cannot meet the energy requirements from the consuming market. The Offshore Supply Vessels (hereafter it is called OSVs) market is becoming booming and the demand for OSVs has never reached the extent like today in previous periods.
In this project, an offshore supply vessel will be designed according to ABS Rules.

It describes setting up CFD cases to analyze the heave and pitch motions of an intact ship model in regular head waves of varying wavelengths. The study also simulates a damaged ship condition and compares the motion responses to the intact case. Areas identified for future work include modeling water intrusion during flooding and simulating more complex sea states with irregular waves.
AMV WITH FOCUS ON HOVERCRAFT
Hovercraft have the ability to travel over land and water surfaces due to pressurized air being pumped into a plenum chamber and escaping out through a skirt. They consist of a hull, skirt, lifting fans, thrust fans and engines. Hovercraft operate by using lifting fans to create an air cushion that lifts the hull above the surface, while thrust fans provide propulsion. They have advantages like traveling over many surfaces and bypassing routes restricted to boats, but also have disadvantages like potential skirt damage and noise. Future applications of hovercraft in Egypt could include military transportation over the new Suez Canal or connecting lakes and tourist sites.

Himanshu ppt
Helicopters have the unique ability to hover, take off and land vertically, and fly in any direction. Their main distinguishing feature is the ability to hover for extended periods using a rotating wing. This allows helicopters to perform a wide range of missions. Helicopters face challenges in high-speed forward flight due to unequal lift distribution across the rotor blades and vibrations. Various configurations have been developed to counter the reactive torque created by the main rotor, including tail rotors, coaxial rotors, and tiltrotors. Airfoil design for helicopter rotors must account for the changing airspeed and angles of attack experienced throughout each revolution. Advancements in computer modeling have improved airfoil designs and reduced the need for wind tunnel testing
RINA - AOG 2017 - Development of Self Installing Deepwater Spar - ARUP - Ashi...
A generic ACE Spar concept has been developed which can further be evaluated to suit different topsides functions like wellhead, drilling, production and compression. The concept comprises a cylindrical spar sub-structure with trussed legs connected to a steel soft tank, and a stiffened plate steel barge deck which will support the topsides. The ACE Spar platform has been designed for water depths of up to 1000m, and topsides facilities to support a throughput capacity of 30,000bpd.
The key features of ACE Spar platform include:
• Self-installing
• Reduced requirement of specialist offshore vessels
• Enhanced project Economics and improved constructability
• Uninterrupted deck-space
• Modular topsides construction
• Less intensive offshore campaign
• Relocatable/de-commissionable
Propulsion
The document provides an overview of different aircraft propulsion systems including gas turbines, ramjet engines, scramjet engines, rocket propulsion, and advanced propulsion techniques. It discusses the operating principles, design considerations, and performance parameters of impulse and reaction gas turbines, ramjets, solid and liquid rocket motors, electric, electromagnetic, and nuclear propulsion. Specific topics covered include velocity triangles, blade cooling methods, ramjet subcritical and supersonic operation, rocket nozzle classifications, solid and liquid propellant selection, ion propulsion, solar sails, and nozzleless concepts.
Multi hull vessels
This document discusses multi-hull vessels, including their history, features, new advancements, and potential drawbacks. It notes that multi-hull vessels originated to provide stability while maintaining a high length-to-beam ratio for speed. Today, many ferries and smaller vessels use catamaran and trimaran designs for their efficiency. New developments include wave-piercing trimarans that can achieve very high speeds and semi-planing mono-hulls with foils for improved seakeeping. However, multi-hull designs also face challenges with docking, construction costs, and applicability in ice.

The companies of Altra Industrial Motion offer many critical drivetrain products utilized in marine applications including clutches & brakes, couplings, universal joints, linear actuators and turning, locking and braking systems
Offshore platforms
Offshore platforms are structures installed in bodies of water to facilitate petroleum drilling and production. There are several types of offshore platforms including fixed platforms, compliant platforms, and floating platforms. Fixed platforms are directly fixed to the seabed and include jacket platforms and gravity-based structures. Compliant platforms, like tension leg platforms, use tethers to connect to the seabed and allow for some movement. Floating platforms are not directly attached and include semi-submersibles and FPSOs (floating production, storage, and offloading vessels).
SEAM-5-GRP2-REPORT.pptx
Discuss different conventional hatch including the structural components, testing methods and watertight and weather tight of the hatch cover.
A cargo hatch or deck hatch or hatchway is type of door used on ships and boats to cover the opening to the cargo hold or other lower part of the ship. To make the cargo hold waterproof, most cargo holds have cargo hatch. Hatch covers of ships are designed to be efficient and cost-effective, as an initial investment and during service, and at the same time should suit the demands of the various types of cargo vessels. With the many changing trends of cargo transportation, it would be expected that the design and structure of cargo holds would change to meet the needs of modern shipping. This is clearly evident with container tonnage and the vehicle decks of the Roll-on, Roll-off (Ro-Ro) vessels. However, the changes in the carriage of general cargoes have been comparatively small. This is possible because most merchandise will suit the more popular container or similar unit load movement.
Hold structures have tended to go towards square corners to reduce broken stowage (BS), and suit palletization, pre-slung loads and the use of the fork lift truck inside the holds. Stowage by such vehicles are aided by flush decks in way of the turn of the bilge, as opposed to the angle turn in the sides of the holds of older tonnage.
Some specialist cargoes, like steel coils , still suit conventional holds and clearly would not be compatible inside containers, because of the shape and weight of each item. As with large case goods or castings, which tend to transport better by means of conventional stowage in the more conventional type vessel. Such merchandise is clearly edging towards heavy-lift type loads and these heavier loads are covered in detail here, alongside the designated heavy-lift ship and project cargoes.
The objective of this chapter is to provide an overall picture of an industry sector which is an essential part of cargo handling and general shipping practice. It does not have such a high profile...
Helicopter Flight - Copy
The document describes a student project to build a miniature helicopter model to understand helicopter flight. The student determined that circular motion of the blades allows helicopters to lift off the ground by redirecting air downward. Several design iterations were needed as the initial base designs were too heavy for the small motors to lift. The student was eventually able to create propellers large enough that could hover the helicopter by bending and redirecting air beneath the craft, demonstrating the physics of how helicopters fly.
Twin Shark Brochure
The document discusses the aerodynamic performance and design of the TwinShark glider. It has a wing area of 15.38 and aspect ratio of 26.5, delivering class-leading performance with low wing loadings of 36-52 kg/m2. The cockpit is spacious and accommodates tall pilots with good visibility. Two engine options are discussed - the TwinShark MS uses a 62hp Solo engine for self-launching while the TwinShark JS will offer jet sustainer technology for cruising at high speeds, based on the proven Shark JS design.
Chap Drive 2
This document discusses ChapDrive, a company established in 2006 that is developing a hydraulic transmission system for wind turbines as an alternative to traditional gearbox systems. It provides an overview of ChapDrive's management team and shareholders. Key points are that the hydraulic system aims to reduce top turbine weights by 50% compared to standard designs and improve reliability by eliminating gearboxes and their failure risks. The document outlines ChapDrive's development progress from early lab testing to field tests of 225kW and 900kW systems and plans to test a 5MW design in 2009-2010 with the goal of supplying hydraulic transmissions to enable larger, more cost-effective wind turbines.
Nautical and engineering terms and concepts .pptx
This document defines and describes various parts of a ship. It explains that the monkey island is a deck located above the bridge that houses navigation equipment. The bridge controls ship movement and navigation. The funnel discharges engine smoke up and away from the deck. The accommodation area houses crew quarters and amenities. Masts carry equipment like radar and navigation lights. The stem, forecastle, bulbous bow, stern, poop deck, side thrusters, rudder, propeller, paint room, emergency generator room, ballast tanks, bunker tanks, cargo gear, samson post, cargo hold, hatch covers, freeboard, hull, anchor, and keel are also defined.
Coastal Research Vessel
This document compares different vessel designs for use as oceanographic research vessels, including monohulls, catamarans, and small waterplane area twin hull (SWATH) vessels. Monohulls have less resistance at lower speeds but higher resistance at higher speeds compared to catamarans. Catamarans have better maneuverability due to dual propulsion but can experience stresses between hulls in rough seas. SWATH vessels combine features of catamarans and semi-submersibles, retaining a large deck area while placing displacement below waves for improved motion control and reduced drag. Design considerations and specifications for the research vessel R/V Kilo Moana, a SWATH ship, are provided.
Design Portfolio_Nick_Przybysz(2)
Nicholas Przybysz's engineering design portfolio includes projects involving composites, structural metals, and automotive design. Some of the highlighted projects are a carbon fiber composite door with ballistic armor for the Tacoma, composite parts for motorcycles and snowboards, and designs for helmets, armor, and aerospace equipment. The portfolio demonstrates experience with composite layups, 3D printing, prototyping, and rebuilding vehicles.
AT SUBSEA VESSEL OPERATIONS CONFERENCE, OSLO (YEAR 2013)
The document describes the design of an ultra deep water rigid and flexible pipelay/heavy lift/DP3 construction vessel. Some key details include:
It is 178 meters long with a breadth of 46 meters and draft of 15.6 meters. It can accommodate 239 people and has a deadweight of 11,000 tons. It is equipped with a 3000 ton crane, 1200 ton reels, 1250 ton carousels, and dynamic positioning system. Extensive analyses and testing were performed to optimize the hull design and ensure operational safety in various sea states.
Steam preservation
The document discusses how SpiralWeld technologies were used to remanufacture brake pull rods for steam locomotives being restored by a preservation society. The rods were corroded and worn, rendering their threads unusable. SpiralWeld analyzed the metal, machined the rods to remove damaged threads, applied overlay welding to rebuild the threads, and machined the rods to their original specifications. This process preserved the original parts and allowed the locomotives to be restored closer to their original condition, helping the preservation society's efforts.
Report on High Rise buildings.
This document provides information about the core of a high-rise building. It defines a core as a vertical space used for circulation and services like elevators, staircases, and mechanical systems. Cores allow efficient distribution of these services to floors. The document discusses different core types and considerations for placement of mechanical and plumbing systems, as well as toilet access. Elevator types, sizes, and fire safety standards are also outlined.

1) CFD methods have advanced to the point where they can provide results equivalent to wind tunnel and towing tank tests for most standard naval architecture computations.
2) Early CFD methods like panel and lifting surface methods provided simplified approximations that captured basic aerodynamic behavior but were limited by their neglect of viscosity.
3) Modern VOF solvers can model complex free surface phenomena like spray, waves, cavitation, and ventilation that are important for high-speed marine foils.

【业务选择办理准则】
一、工作未确定，回国需先给父母、亲戚朋友看下文凭的情况，办理一份就读学校的毕业证【q/微:1954292140】文凭即可
二、回国进私企、外企、自己做生意的情况，这些单位是不查询毕业证真伪的，而且国内没有渠道去查询国外文凭的真假，也不需要提供真实教育部认证。鉴于此，办理一份毕业证【q/微:1954292140】即可
三、进国企，银行，事业单位，考公务员等等，这些单位是必需要提供真实教育部认证的，办理教育部认证所需资料众多且烦琐，所有材料您都必须提供原件，我们凭借丰富的经验，快捷的绿色通道帮您快速整合材料，让您少走弯路。
留信网认证的作用:
1:该专业认证可证明留学生真实身份
2:同时对留学生所学专业登记给予评定
3:国家专业人才认证中心颁发入库证书
4:这个认证书并且可以归档倒地方
5:凡事获得留信网入网的信息将会逐步更新到个人身份内，将在公安局网内查询个人身份证信息后，同步读取人才网入库信息
6:个人职称评审加20分
7:个人信誉贷款加10分
8:在国家人才网主办的国家网络招聘大会中纳入资料，供国家高端企业选择人才
→ 【关于价格问题（保证一手价格）
我们所定的价格是非常合理的，而且我们现在做得单子大多数都是代理和回头客户介绍的所以一般现在有新的单子 我给客户的都是第一手的代理价格，因为我想坦诚对待大家 不想跟大家在价格方面浪费时间
对于老客户或者被老客户介绍过来的朋友，我们都会适当给一些优惠。
选择实体注册公司办理，更放心，更安全！我们的承诺：可来公司面谈，可签订合同，会陪同客户一起到教育部认证窗口递交认证材料，客户在教育部官方认证查询网站查询到认证通过结果后付款，不成功不收费！

Connect Conference 2022: Passive House - Economic and Environmental Solution...
July 8th 2014 - Presentation by Doug Schicler and Davide Tagliapietra
- 1. schickler tagliapietra Foil engineering developments. New applications on mono and multi-hull sailing yachts
- 2. Overview • Company Background • Recent Projects • Object of Foil Use • Engineering Challenges • Case Studies • Future Work
- 3. Schickler Tagliapietra • Founded in 32nd America’s Cup • Involved in 4x AC, 1x VOR • Design and Engineering • Simulation Based • Beyond Structural Specialist
- 4. Recent/Current projects • Gunboat G4 FEA, VPP, foil design • Whites Dragons foiler • Challenge Italia C class • Mini 650 prototype • Kuka Light • Luna Rossa AC34 (external) • Luna Rossa AC35 (full time)
- 5. Object of foil use • Trading wetted surface for induced drag, obviously
- 6. Object of foil use • Moment influence – Roll – Trim
- 7. Object of foil use • Uncoupling (even reversing) force balance from e.g. roll
- 8. Object of foil use • Trading wetted surface for induced drag • Moment influence • Uncoupling of force balance from vessel movement Along with drag reduction, foiling can allow for decoupling of sail carrying power from e.g. heel angle, mass
- 9. Degrees of Freedom • 6 DOF VPP key to balancing trade-offs surge, sway, heave, pitch, roll, yaw • Must be customizable for novel systems • Must have user trim variables available to optimizer • Allow for coupling trim variables to one another Custom VPP best choice Use confirms value of optimum control of otherwise unstable systems
- 10. Challenges in trim variables • Range of movement to the maximum possible • Concentrated load carrying on foils • Controllable and precise positioning and adjustment • Loads passed to vessel via mechanical systems This is where ST sets itself apart
- 11. Case study: Pegaso 60’ Before you Run, you have to walk… 5 DOF Keel System • Canting • Lifting • Rotating bulb • Pitch windward winglet • Pitch leeward winglet
- 12. 1. UPWIND full power Case study: Pegaso 60’
- 13. Keel is on centerplane and bulb winglets are positioned parallel to the blade to maximize the lateral area. Each one is independently angled at an optimal angle with upper blade and strut generating high lift coefficient as slotted flaps Case study: Pegaso 60’ 2. UPWIND light air
- 14. Case study: Pegaso 60’ 3. DOWNWIND VMG mode
- 23. Case Study: C – Class Design: PARAMETRIC MODELLING & OPTIMIZATION PROCESS
- 24. • CANT RANGE : 28 ° • RAKE RANGE : 10 ° • YAW RANGE : 7 ° Daggerboard Control System
- 25. • Spherical Surface Upper Bearing • Flush Bottom Bearing
- 27. • Rake Range: 10 ° • Tilting • One pin removal • Stern with Recess • Ball at the Bottom Bearing • Partially Suspended Rudder Blade – 25% under hull Rudder Rake Control System
- 28. Rudder Rake Control System
- 30. Case study: Offshore monohull • Lower power to weight ratios can gain from foiling Glide Free Laser only confirms… • Trade-offs differ from catamarans, moth class • Limit is engineering (or rules) • Offshore canting keel yachts – Light IMOCA yachts – Mini proto – Similar other reaching boats
- 32. Mini 650 Foils for trim control Already employed in Minis
- 33. Case study: Offshore monohull • Lightweight canting keel yacht • Add lift foil to existing straight dagger in existing case • Effectively no limit from rules • VPP study proves outboard stability generating foil helps at higher speed, better than inboard foil as AC72 Combination of moment generation and drag reduction • Rake of dagger inadequate, need to use flap system
- 34. Foil Variations
- 35. Case study: Offshore monohull Conflicting High and Low pressure sides • Offset foils longitudinally • Introduce fence • Swept foil to position lift • Need to house mechanism • Acute dihedral
- 36. Case study: Offshore monohull
- 37. Case study: Offshore monohull
- 38. Case study: Offshore monohull
- 39. Case study: Offshore monohull Challenges met with solutions • Foil and flap aircraft influenced • Flap angle through 30 deg, swept • Spline and drive allows for adjustment • Dihedral can be modified up to 10 deg, exchanging parts • Full craft weight can be carried on foil/flap • Sealed housing to maintain lubrication
- 40. Future work • Ultralight foiling transportable catamaran – Compotech Inflatable Technology – Low cost – True beach cat
- 41. Future Work • Bonezzi Moth – New design based on novel experimentation – Made in Italy
- 42. Thank you for your attention! Special mention to: Massimo de Luca Peppe Musca Vieri Abolaffio Andrea Vergombello Antoine Coadou Federico Patti
