OPEN WATER - SeaVax is seen here during open water floatation trials. Please note that this is a small (proof of concept) version of any ocean or river floating dustcart that we hope will be tested on the south coast of England as the project progresses. SeaVax is a selective filtration machine that can be configured to target solid plastics and particles. The machine could also be used in oil spill emergencies, or as a selective fishing vessel. The platform could thus be useful in many ways in the future. Eventual classification will depend on the function and performance of the vessel.
The description and classification of SeaVax and AmphiMax research workhorses and the Elizabeth Swann autonomous solar powered vessels is one of the overall project development targets where no such vessel format currently exists, for which perhaps, funding may be provided by the United Nations, G20 or other long-term beneficiaries.
There is no legal requirement for any boat or ship builder to seek classification or to construct a vessel to any particular formula for approval by any classification society.
Where a design is pioneering, involving cutting edge innovation like the SeaVax selective filtration or selective fishing vessel, the Cleaner Ocean Foundation considers that it may be appropriate as part of project development to work with the Societies that may eventually assist international ocean cleaning operators, to classify ocean cleaning craft, subject to funding being available for such negotiations and eventual agreements. Hence, this is a goal once any design has reached a stage where a specification for classification may be drawn up - and where such formulation is bound to be an expensive exercise and a burden for a charity involving legal and other experts.
Regardless of the considerable additional administrative burdens, at the appropriate juncture COF will seek to generate additional funding to carry out such tasks, or to put in place an alternative that achieves the same.
DNV-GL - Claim to be proactive and flexible. They have in the past encouraged innovation in terms of clean energy for shipping.
In naval terms, vessels are sometimes launched with a temporary designation and reclassified once their capability is determined. Hull classification varies from country to country. There is no international agreement as to class.
A heavily modified or re-purposed ship may receive new symbols and classification, and either retain the hull number or receive a new one. The system of naval symbols has changed a number of times since it was introduced in 1907, and for this reason ships' symbols sometimes change without any physical alterations to a ship.
VERITAS - Classification is a system to safeguard life, preserve the environment and protect assets. It applies principally to ships and offshore oil and gas units.
NATIONAL OCEANIC & ATMOSPHERIC ADMINISTRATION HULL CODES
AGE: General Purpose Experimental Ship (AGE = Auxiliary General Experimental)
LCP: Landing Craft, Personnel
SeaVax vessels will be experimental, conducting oceanographic
research and surveillance generally. The object is to refine
and prove the ocean cleaning concept, that also involves
avoiding plankton, fish and marine mammals selectively. it may
then be appropriate to assign such craft the AGE or RV code to
include: O, where the vessel is a blue water, endurance
machine. Hence: ORV. But where solar and wind power is a
factor in the experimental stages: AGE. Clearly, the
classification will change once the experimental stages are
passed and ocean cleaning operations begin.
SeaVax fits much of this description, where hydrographic sounding and environmental sensor arrays are to be included, subject to suitable funding being available. Examples of an oceanographic research vessel include the NOAAS Ronald H. Brown and the Chilean Navy Cabo de Hornos.
SeaVax will carry acoustic fish-avoiding equipment, but also
seawater sampling instruments for acidity and other
parameters, the vessel would be a floating laboratory. It may
then be described as conduction anti-fishing, or selective
fishing research. In order to avoid fish you have to be able
to detect them differentially from plastic or other marine
Classification is then time related, it expiring, regardless of the fact that the vessel has not changed physically.
After any accident such as a fire, a ship has to be resurveyed to establish its classification. The advantages for a ship owner to have their vessels classified and to keep them ‘in class’ are numerous, as the construction and maintenance of a ship up to the standard required is mandatory for almost all insurance, chartering, financing, and so on, and also for the issue of statutory certificates required by international conventions such as SOLAS.
In view of the specialist function of SeaVax and the not-for-profit motives, it may benefit any international alliance to provide specialist surveys and insurance to reduce the operational overheads and streamline missions.
BUREAU SHIIPING - The heart of their classification organization, ABS Rules & Guides are derived from principles of naval architecture, marine engineering and related disciplines.
Currently, more than 50 organizations worldwide describe their activities as including marine classification, some of which are listed below. Twelve of these are members of the International Association of Classification Societies. The largest are DNV GL, the American Bureau of Shipping, Nippon Kaiji Kyokai (ClassNK) and Lloyd's Register. Classification societies employ ship surveyors, material engineers, piping engineers, mechanical engineers and electrical engineers, often located at ports and office buildings around the world.
In 2003 there were nineteen classification societies. Among the best known are the American Bureau of Shipping, Bureau Veritas, and Lloyd's Register, the latter granting the well-known classification 100A1, where:
100 = suitable for seagoing service,
A = constructed or accepted into Lloyd's Register class and maintained in good and efficient condition, and
1 = good and efficient anchoring and mooring equipment.
The mark indicating that a ship has been built to Lloyd's Register class is a Formée Cross, sometimes erroneously described as a Maltese Cross. It was adopted in 1853 as a distinguishing mark for all ships built under special Lloyd's survey anywhere in the world. Currently most classification societies encourage ‘running surveys’ whereby ships on constant voyages can have inspections on a regular basis, avoiding the need for a costly lay-up every fourth or fifth year.
Lloyd's Register of [British and Foreign] Shipping is a British publication that describes, classifies and registers vessels according to certain criteria of physical structure and equipment, to enable underwriters, shipbrokers, and shipowners more easily to assess commercial risk and to negotiate marine insurance rates.

BUILDING and HULL CONSTRUCTION CERTIFICATES
The Lloyd's "Building Certificate" and "Hull Construction Certificate" do not involve ongoing classification surveys. ABS, on the other hand, offers a "Hull Certificate" in which they duplicate the classification process up to the point of delivery, at which time ABS involvement ends. Unlike Lloyd's, ABS also offers a "Plan Review" that takes the same hard look at the hull design and construction plans that they use for a full classification, but no construction surveys are performed and machinery systems are not included.
Dave Christiensen estimates that the added cost is about 3 percent of the total, and probably adds 300 to 400 manhours of engineering time to prepare extra drawings and plans.
& DEVELOPMENT - ClassNK offers a broad range of services that encompass every aspect of ship classification from the approval of vessel and machinery plans to the survey and registration of the ship and ship installations, approval of materials, equipment and outfitting gear, as well as the assessment and registration of ship safety management systems and security systems.
ABS is easier to deal with than Lloyd's if you want to try an unusual design or construction process. If you can back up your idea with facts and figures, ABS will approve it while Lloyd's tends to take a more conservative view of any deviation from the norm.
ABS has made a concerted effort to reach the yachting market, and ABS representative Bob Curry worked extensively with the Offshore Racing Council's Technical Committee and several naval architects, notably Gary Mull and Olin Stephens, to devise fair and realistic scantling rules for offshore racing yachts. The result is a comprehensive guide, "Building And Classing Offshore Racing Yachts," that is both up-to-date in terms of technology as well as in a simple engineering format for designers to use.
Lloyd's Register Group Limited (LR) is a technical and business services organisation and a maritime classification society, wholly owned by the Lloyd’s Register Foundation, a UK charity dedicated to research and education in science and engineering.
Classification societies exist in the shipping industry for insurance purposes to provide a uniform worldwide standard, but why is this needed in yachts where a normal surveyor could provide much the same service at far lower cost? For one thing, yachts have become small ships with all the myriad systems and complexities that would be beyond the grasp of any single surveyor and, second, with the growing variety of materials and techniques, the societies provide an information service that shares the success of certain methods and remembers the failures of others.
True or not, it is debatable as to whether a buyer would want a boat built to society standards. One well-known builder noted that it is impossible to build the high-speed motor-yachts, now so popular, to classification because of the sacrifices necessary to keep the weight to a minimum.
societies say that they have been classing high-speed patrol craft and other speed-oriented vessels for many years, and suggest that the builder is probably cutting many corners in search of an extra knot or
two. Whereas the builder may simply have evolved a method of
improving performance that the societies have not yet
NGAWI BEACH - This is how they recover boats on the beaches of New Zealand. It is a crude but cost effective development of trailer launching that is commendable in terms of practicality..
