Our constructions

We build in steel and all our welders are constantly updated with special training courses and are all in possession of licenses recognized by the most important organizations of international ship certification and come regularly re-qualified. About our ISA Superyachts they can be registered under any classification institute (Rina, Bureau Veritas, Abs ...) at the request of the owner and if this is not requested, each model is built anyway as if the request had been received.The certification adds value and prestige to the boat and guarantees the owner constant surveillance by the owner of the certifying body throughout the life of the boat. Certification is not, as many may think, a waste of useless economic resources, but an added value for the boat. The certification includes many obligations for the Shipyard that without it could work based on the concept of “Savings” rather than on that of future safety and durability. Every detail of the ship is taken into consideration and every detail is given a lot of importance. For each component installed a specific regulation is followed which provides all possible indications on how to install it, assemble it and work it. Nothing is left to chance or to the good faith of the yard as happens in other certifications.The only "CE" certification adopted by many shipyards is absolutely not comparable with the "real" naval certifications. Just take a look at the documentation that the yard is obliged to issue in order to be aware of this. In the case of a “CE” certification, the manufacturer of the asset, or rather the construction site, is required to issue a declaration of conformity (similar to a self-certification) and a owner's manual. In the case of a Ship the documentation in class "RINA or other classification body" accompanying the ship is completely different. Thousand of sheets containing diagrams, calculations, drawings, photos, certifications etc, will accompany yours ship.

Tugs

Tugs perform a variety of tasks and their design varies accordingly. They move dumb barges, help large ships manoeuvre in confined waters, tow vessels on ocean voyages and are used in salvage and fi refi ghting operations. Tugs can be categorized broadly as inland, coastal or ocean going. Put simply, a tug is a means of applying an external force to any vessel it is assisting. That force may be applied in the direct or the indirect mode. In the former the major component of the pull is provided by the tug’s propulsion system. In the latter most of the pull is provided by the lift generated by the fl ow of water around the tug’s hull, the tug’s own thrusters being mainly employed in maintaining its attitude in the water. The main features of a tug (A Figure ) are an effi cient design for free running and a high thrust at zero speed (the bollard pull ), an ability to get close alongside other vessels, good manoeuvrability and stability. Another way of classifying tugs is by the type and position of the propulsor units: (1) Conventional tugs have a normal hull, propulsion being by shafts and propellers, which may be open or nozzled, and of fi xed or controllable pitch, or by steerable nozzles or vertical axis propellers. They usually tow from the stern and push with the bow. (2) Stern drive tugs have the stern cut away to accommodate twin azimuthing propellers. These propellers, of fi xed or controllable pitch, are in nozzles and can be turned independently through 360° for good manoeuvrability. Because the drive is through two right angle drive gears these vessels are sometimes called Z-drive tugs. They usually have their main winch forward and tow over the bow or push with the bow. (3) Tractor tugs are of unconventional hull form, with propulsors sited under the hull about one-third of the length from the bow, and a stabilizing skeg aft. Propulsion is by azimuthing units or vertical axis propellers. They usually tow over the stern or push with the stern.

Icebreakers and ice strengthened ships

The main function of an icebreaker is to clear a passage through ice at sea, in rivers or in ports so that other ships can use the areas which would otherwise be denied to them. Icebreakers are vital to the economy of nations such as Russia with ports that are ice bound for long periods of the year and which wish to develop the natural resources within the Arctic. Icebreakers need: ● To be specially strengthened with steels which remain tough at low temperature. ● Extra structure in the bow and along the waterline. ● High power propulsion and manoeuvring devices which are not susceptible to ice damage. The shape of the stern is important here. ● A hull form that enables them to ride up over the ice. This is one way of forcing a way through ice; the ship rides over the ice edge and uses its weight to break the ice. The ship may be ‘ rocked ’ by transferring ballast water longitudinally. The hull is well rounded and may roll heavily as protruding stabilizers are unacceptable. ● Good hull sub-division. ● Special hull paints. Icebreakers are expensive to acquire and operate. Other ships which need to operate in the vicinity of ice are strengthened to a degree depending upon the perceived risk. Usually they can cope with continuous 1 year old ice of 50–100 cm thickness. Typically they are provided with a double hull, thicker plating forward and in the vicinity of the waterline, with extra framing. They have a fl at hull shape and a rounded bow form. Rudders and propellers are protected from ice contact by the hull shape. Inlets for engine cooling water must not be allowed to become blocked.

Fishing vessels

Fishing vessels have evolved over thousands of years to suit local conditions. Fish which live at the bottom of the sea like sole, hake and halibut and those which live near the bottom like cod, haddock and whiting are called demersal species. Those fi sh which live above the bottom levels, predominantly such as herring and mackerel, are called pelagic species. There are also three fundamental ways of catching fi sh: (a) by towing trawls or dredges; (b) by surrounding the shoals by nets, purse seines; (c) by static means, lines, nets or pots. These distinctions enable fi shing vessels to be classifi ed in accordance with Figure ( A 1 ) . The commonest type of fi shing vessel is the trawler which catches both demersal and pelagic species. The trawl used for the bottom is long and stocking shaped and is dragged at a few knots by cables led to the forward gantry on the ship. When the trawl is brought up it releases its catch in the cod end down the fi sh hatch in the trawl deck. Operations are similar when trawling for pelagic species but the trawl itself has a wider mouth and is altogether larger. Trawlers suffer the worst of weather and are the subject of special provision in the freeboard regulations. They must be equipped with machinery of the utmost reliability since failure at a critical moment could endanger the ship. Both diesel and dieselelectric propulsion are now common. Ice accretion in the upperworks is a danger in certain weather, and a minimum value of GM of about 0.75 m is usually required by the owner. Good range of stability is also important and broaching to is an especial hazard. Despite great improvements in trawler design signifi cant numbers of vessels are lost every year and many of them disappear without any very good explanation. It is probable that such losses are due to the coincidence of two or more circumstances like broaching to, open hatches, choked freeing ports, loss of power, critical stability conditions, etc. To give adequate directional stability when trawling, experience has shown that considerable stern trim is needed, often as much as 5 degrees. Assistance in fi nding shoals of fi sh is given by sonar or echo sounding gear installed in the keel. No modern trawler is properly equipped without adequate radar, communication equipment and navigation aids. A typical stern fi shing trawler is shown in Figure ( A 2 ).
