Subject: 50 Years of Hovercraft in the USA Put into Perspective
Author: Warwick Jacobs, Trustee, the UK Hovercraft Museum.


Description:

Although the hovercraft was officially invented in the UK back in 1955, the US has had a long
association with it and has now seen half a century of activity and contributions to it. From
GEMs (Ground Effect Machines) to ACVs (Air Cushion Vehicles) to SES (Surface Effect
Ships), the “hover craft” has had a presence in the US, and Warwick will discuss both its
military and civilian roles and explain the successes and failures. From the San Francisco ferries
and Vietnam conflict in the 1960s to the dream of a 100-knot Navy to present day giant military
craft worldwide, he will trace the rich diversity of hovercraft and what the future may hold. He'll
touch on today's hovercraft sporting and cruising clubs and their great differences from the UK.

Subject: LNG Fuel for Advanced Ships
Author: Philip Wasinger
MAN Diesel North America.


Description:
Use of LNG (liquefied natural gas) as ship fuel is growing rapidly in response to its attractive price, environmental benefits, and increasing availability. About 350 LNG-fueled ships are in service and over 100 more are in advanced planning or on order.
The fact that LNG is stored at -260 degrees F and that its energy density is only 60 percent that of diesel fuel means there must be significant changes in a ship's engines, its tankage and fuelhanding systems, and its overall design and operation. What are these changes and how are different types of ships affected? Is LNG suitable for smaller vessels and high-speed ships as well as large conventional ships? One of the latest LNG-fueled ships is a 50-knot Incat vehicle/passenger catamaran ferry driven by a pair of LM2500s. With LNG its fuel bill will be much lower than otherwise.

Ride Control for High-Performance Ships

Alan Haywood and Benton Schaub Naiad Dynamics US, Inc.

Even moderate waves can generate substantial forces on a ship or boat and produce significant motions that can disturb passengers and cause damage to cargo and equipment. This is especially true for smaller high-performance vessels encountering waves at high speed. Ride control systems have been developed to reduce these motions significantly, and a major developer has been Maritime Dynamics, Inc. (MDI), now part of Naiad Dynamics. The presentation will provide an overview of ride control devices (fins, trim tabs, interceptors, T-foils and air cushions), their incorporation into systems for ride control, and examples of their applications and resulting effectiveness in a range of high-speed ships. These will include commercial ferries, private yachts, and military vessels (for which the technology has been largely adopted from the commercial sector). A particular focus will be ride control systems on currently operating trimarans.

T-Craft —What, Why & How?

Robert Wilson and Dr. Alfred Skolnick

The T-Craft is an amphibious concept combining the best capabilities of the catamaran, surface effect
ship and air cushion vehicle. It answers ONR's requirements for a seabase-to-shore “connector” capable
of self-deployment across open ocean, high speed while fully-loaded, operation in relatively shallow
water, good seakeeping for at-sea cargo transfer, and fully amphibious delivery “feet dry” on the beach.
Results show sufficient technological maturity to permit a full-scale T-Craft demonstrator to be designed
and built today. The presentation covers the importance of the T-Craft concept, its key technologies,
development of its configuration by three design agents, and technologies warranting further attention in
the near term.

The SES SeaTrain

Dr. Robert M. Scher of Alion Science and Technology

The SES SeaTrain is an articulated cushion-borne marine vehicle consisting of multiple units connected in such a way that they can be added or removed as desired. The analogy with a railway train is clear. Its hinged connections use coupler designs based on articulated tug-barge practice. The vehicle's ability to deflect vertically, unlike a rigid SES, allows an extremely high length-tobreadthratio without requiring increases in freeboard, wet deck clearance, draft, and structuralweight. Very low propulsive power per ton has been confirmed both theoretically and by model
testing. The presentation will review recent design efforts, experiments, and possible future developments. Potential commercial applications will be discussed as well as possible use in military sealift

Bob Scher has been a student of advanced marine transportation concepts for nearly 40 years. He is Senior Principal Naval Architect at Alion Science and Technology, and has been at Alion (and formerly JJMA) for over 26 years. Recent projects have included the design, analysis, and model testing of advanced vehicle concepts for high-speed marine and amphibious transport, the development of ship-to-ship transfer systems for containers and rolling-stock at sea, and small craft and amphibious vehicle design efforts.

Hydrofoils & Chesapeake Ferries

Mark Rice, President and Jeanne Torstenson, Naval Architect of Maritime Applied Physics Corp.

Non-traditional transportation solutions have been growing, driven by increasing energy costs and emissions constraints, and water transportation itself is increasingly seen as part of the solution to land transportation problems. A ship or ferry may offer a shorter direct route or relieve congested highways by means of parallel water routes. New technologies receive much attention, but some that have been around awhile are particularly relevant now. The hydrofoil is a prime example. It can substantially reduce the power and fuel consumption to make a respectable speed and can be highly cost-effective.
Maritime Applied Physics Corporation has been developing new passenger hydrofoil designs and has also done the groundwork for some specific ferry routes on the Chesapeake Bay. They will present both their hydrofoil designs and their concepts for hydrofoil passenger services on the Chesapeake.

Fast Track Amphibian
Kenneth G. Wernicke, CEO Fast Track Amphibian, LLC


Previous road-capable amphibious vehicles have performed well either on land or on water but noton both. And all have employed separate systems for propulsion in the two environments, resultingin high complexity, weight and cost, which has constrained their development and use.
A promising new amphibian has been developed that has a single power plant, employs tracks for propulsion on both land and water, and attains high speed on land and on water. The prototype test vehicle, FastTrack 1, has achieved 65 mph on roads and 39 mph on water powered by a 148 horsepower engine. The secret lies in countering the Coanda effect on the tracks. Concepts have
been developed for larger vehicles for various purposes: patrol, emergency response, riverine warfare, etc. They could also be employed as amphibious buses, passenger ferries, delivery vehicles, and so on. The tracked amphibian can negotiate shorelines and terrain that would stop a hovercraft. The presentation covers the development of the concept, explain how the tracked propulsion
works, and show videos of the prototype operating.

Ken Wernicke led the design, fabrication and testing of the FastTrack 1 concept demonstrator and performed the analyses and correlation of its performance and characteristics. He holds a BS and MS in Aerospace Engineering from the University of Kansas, is a Registered Professional Engineer in Texas, and holds numerous patents. He is the acting CEO of Fast Track Amphibian LLC and also consults on varied rotary wing aircraft projects. From 1955-1990 he worked for Bell Helicopter, where he was Chief Engineer for the XV-15 Tiltrotor and Director of Engineering for the V-22 Osprey Tiltrotor Aircraft.

T-Craft TransformableThe Amphibious Craft
Kelly Cooper, Program Officer, Office of Naval Research


The T-Craft Program is an Office of Naval Research effort to develop a prototype transformable amphibious craft. The T-Craft will be capable of self-deploying from an intermediate support or advanced base to a sea base (2500 nm), taking on cargo (primarily wheeled and tracked vehicles) in high sea states (SS 4), transporting this cargo to the beach (up to 500 nm unrefueled), then transforming into a completely amphibious vehicle and delivering its cargo “feet dry” on the beach. It will carry 4 to 10 times the payload of current craft (300 LT Threshold / 750 LT Objective).
Phase II of the program—technology development, detail design, and modeling and simulation—is currently underway with three contractor teams: Alion, Textron, and Umoe Mandal. Following a downselect in May 2010, Phase III—prototype construction, demonstration, and testing—will extend to 2014.

Connectorless SEATRAIN for High Speed, High Payload, and Austere Port Access

by Gabor Karafiath, NSWCCD, Resistance & Propulsion Division

Several "seatrain" concepts have been proposed in recent years. The design philosophy and reasons for examining the twin tail connectorless seatrain concept developed at NSWCCD are explained. Model test results indicate a 37 to 44 percent reduction in resistance per unit at high speed. The capability to carry large cargoes normally associated with sealift ships is maintained, and at the end of the voyage the units can disengage to enter shallow and restricted-size ports. Some of the complexities of the concept will be described, including motions and loads, structural design, and propulsion with vectored thrust. Its operational flexibility and benefits will be explained with regard to lighterage, and sealift missions.

Gabor Karafiath is a senior staff Naval Architect at NSWC Carderock Division, where he has worked for 35 years in the area of resistance and powering for surface ships, high-speed craft, and advanced marine vehicles.

A Pentamaran Bridge Over the Sea

Mr. Stephen P. Flott
Founder and Chairman of the Board, SeaBridge, Inc.

SeaBridge Inc. is proceeding with plans to build and operate a fleet of large high-speed ro-pax ferries (roll-on/roll-off vehicles plus passengers) along the US East and Gulf coasts.  Previously referred to as short sea shipping but now as "America's Marine Highways," this new service will be an attractive alternative to clogged highways and uncertain travel times for truckers and motorists.  It will also reduce rail and highway congestion in an environmentally friendly and profitable manner. 

Early plans envisioned conventional monohulls carrying 1600 passengers and 2400 lane-meters of vehicles.  Subsequently the Pentamaran design, by Nigel Gee and Associates, was shown to be capable of both greater capacities and higher speed for the same investment, and it was adopted.  The ship will be over 900 feet long and have a 42-knot service speed.  Details of its design, including technical and operational characteristics and notable features for freight vehicles and passengers and Intended ports and routes are included.
