Navalimpianti Tecnimpianti is the international leader in the design and supply of marine equipment for passenger and merchant ships, and navy, offshore and mega yachts. The group has already supplied more than 15,000 plants and pieces of equipment all over the world.
For the vessel Carnival Dream (hull 6151), built at Fincantieri Monfalcone, Navalimpianti Tecnimpianti has projected, designed, fabricated and delivered:
- One fixed outboard launching systems (FOLS) for lifeboats and tenders, and telescopic davits for rescue boats and life rafts
- 29 FOLS with hydraulic winch suitable for partially enclosed lifeboats, each with a capacity of 150 persons
- One FOLS with hydraulic winch, suitable for partially enclosed cruise tender/lifeboats, with a capacity of 150 persons
- Two telescopic rescue hydraulic davits with electric winch suitable for rescue boats, each with a capacity of six persons
- Eight telescopic electric davits (type GDET) with electric winch suitable for life rafts, each with a capacity of 35 persons
- Two telescopic electric davits (type GDETS) with electric winch suitable for life rafts, each with a capacity of 35 persons
Main characteristics of FOLS (life and tender boats)
This fixed launching system type is designed in conjunction with a particular ship’s design that allows the boats to be installed in a fixed position outboard below the protrusion of deck five. The launching systems are of a fixed type since the boats are directly launched and recovered from their stowed position without any travelling movement.
Each fixed launching system is designed for semi-enclosed tender boats or lifeboats for 150 persons and is dimensioned to launch the boat fully manned (full load condition) from the deck level to the water, in all conditions stated by the rules for ship abandonment.
Each fixed launching system set includes two fixed arms and one hydraulic winch with relevant fittings, signals and the electric cabinet, one double pulley block under deck and the marine fittings. Each arm consists of a fixed structure connected to the deck, on which are installed all hanging and reeving pulleys and of course the securing mechanism of the blocks. The system also includes the lashing system, the winch’s remote control and the anti-rolling system of the boats.
The winches are installed outboard along a structural strong catwalk built in the ship structure and positioned in the service spaces between the boats. In front of the winches, below deck five, the double pulley block is installed.
The fixed arm consists of a strong beam connected in two points to the longitudinal structures of the upper deck. This arm supports both the pulleys hanging the lower block and the reeving pulley. The adjusting turnbuckle is installed at the rear top of the fixed arm, with the wedge socket at the fixed end of the fall. At the side of each beam the supporting structure of the lashing and anti-rolling device with the service platform is installed.
Main characteristics of rescue boat davit system
The davit consists of one telescopic arm with one electric winch. The davit arm is divided in the fixed frame and in the trolley beam. The fixed frame is connected to the ship’s structure and it supports the trolley beam; it is bolted directly on the rear part of the winch. The trolley beam is moved by the hydraulic cylinder always fed by the stored power system through the distribution valve of the control stand. When the trolley arm is fully extended, the davit is ready to operate as a normal gravity davit. When fully hoisted, the rescue is fastened to the trolley beam by
a suitable cradle with suitably shaped tree guides.
Rescue boat local hydraulic system: the hydraulic system is intended to operate the trolley arm by means of one hydraulic stored power source always available from any other power supply of the ship. This power is stored inside one hydraulic accumulator pressurised by one or two nitrogen bottles.
Rescue boat local electric and automation systems: there are two independent electric systems; one for the electric winch and one for the hydraulic travelling system.
