Types of liferafts

At present, the liferafts may be classified into throw over board type (OCEANO), davit launched type (OCEANO DL) and open reversible type (OCEANO OR).

The throw-overboard inflatable liferafts may be thrown overboard by man power or may be dropped into the sea by gravity, or may float free by means of the hydrostatic release when the ship sinks and then inflate on the sea surface. The survivors are to board by climbing down the shipside embarkation ladder or by other means.

The davit-launched liferafts are hoisted by a special davit and slewed outboard, and the raft is inflated at the outboard position by pulling the painter line, then the survivors can board the liferaft from the deck side. When the davit launched liferaft is loaded, then it is lower away onto the sea surface. The davit launched liferafts may also be used as a throw-over board liferaft.

The open reversible inflatable liferafts are used as a thrown overboard liferaft (see above). The main difference is that the floor of the liferaft is between the buoyancy tubes and after the inflation, the occupants can board immediately, whichever side of the liferaft is above the sea level.

The inflatable liferafts may also be classified according to the navigation area. For the throw over board inflatable liferafts & for the davit launched inflatable liferaft, the ship operates into A-type liferaft for ship engaged in unrestricted navigation area and the B-type liferaft for ship engaged in coastal or near-coastal navigation areas. The open reversible inflatable liferafts are applicable for high-speed crafts engaged in warm sea area in China and in the international voyages only.

Construction of Inflatable Liferafts

Throw over board (OCEANO) & the davit launched (OCEANO DL) liferafts :
These inflatable liferafts are mainly composed of four parts: the upper and lower buoyancy chambers, the canopy and arches, and the floor (Figure 1 & Figure 2).

The lower buoyancy chamber and the boarding ramp form a separate air cell, and the upper buoyancy chamber and the canopy arches are connected by one way valves to form one air cell. These air cells are inflated into shape by the CO2 gas stored in the bottles. The floor is also a separate air cell and this is inflated by hand bellows after boarding. Several stabilizing pockets are attached to the underside of the floor along the periphery of the lower champer, to increase the stability of raft at sea.

Two entrances fitted at both ends of the liferaft. At the front entrance a boarding ladder and a towing device are fitted, and at the back entrance a boarding ramp is fitted to enable persons to board the liferaft from the sea (the boarding ramp is connected to the lower chamber through an one-way valve; no boarding ramp is fitted to B-type liferaft except for the boarding ladder). Both the boarding ramp and boarding ladder are fitted for use by the persons in water. Lifelines are bucketed around both outside and inside the liferaft as a hand hold for persons.

Open Reversible (OCEANO OR) inflatable liferaft :
This inflatable liferaft is composed of upper and lower buoyancy tubes, floor and so on (Figure 3).

The section of the upper and lower buoyancy tubes is round-shaped; the appearance of the body is round or polygon when it is looked from above.

The upper and lower buoyancy tubes and its connected inflation tubes are two separate gas chambers. These chambers have their own inflation system and can be inflated automatically by steel cylinders with mixed gas of CO2 & N2 at the same time. The floor is made of single-layer antiskid fabric, which is between the two buoyancy tubes. Both the upper and lower sides have one or two discharge systems. The buoyancy tubes are equipped with lighting or indication lights and reflective materials.

The upper and lower buoyancy tubes are each equipped with a safety valve and an inflation/deflation valve. The upper and lower buoyancy tubes are each equipped with 1-2 semi-rigid boarding ramps. The upper and lower buoyancy tubes are each equipped with certain quantities of water-pockets on their tops.

Inflatable liferaft equipment

The inflatable liferaft equipment is provided in accordance with the provisions as indicated in the LSA Code, as lastly amended. The equipment of every liferaft carried by ships engaged on international voyages is as listed in the following table :

Note : The items and quantity of equipment will be different depending on the navigation area in which the ship is engaged. The throw over board type (OCEANO) & davit launched type (OCEANO DL) inflatable liferafts have 2 types of equipment packs : Pack A and Pack B, according to the navigation area in which the ship is engaged. The open reversible type (OCEANO OR) inflatable liferafts have standard emergency equipment pack (HSC Pack) according to HSC Code regulations.
