IZAR to build chemical tanker for Chile's Ultragas
Spanish shipbuilder IZAR has won a contract to construct a 22,700 m3 oil product chemical tanker for Chilean shipowner Ultragas Internacional. .
The tanker will be built at the Gijon shipyard in northern Spain.,
The ship will have 28 duplex stainless steel tanks able to carry over 800 IMO I and IMO II chemical cargoes as well as refined oil products.It has been designed with double hull and double bottom in the way of the cargo tanks. Vertically corrugated bulkheads and outer side reinforcement of the upper deck allow an unobstructed cargo area structure.
Five of the transverse bulkheads are flat sandwich bulkheads with a cofferdam, making it possible to carry cargoes at different temperatures.
Main particulars of the tanker will be
- Length overall: 161.23 m
- Length bpp: 152.10 m
- Molded breadth: 23.00 m
- Molded depth: 12.95 m
- Draft: 9.25 m
- Service speed: 15.5 knots
- Deadweight: 19,000 t
- Crew: 28
Capacities will be
- Cargo tanks: 22,697 m3
- Clean ballast: 8,517 m3
- Diesel oil: 92 m3
- Fuel oil: 1,419 m3
- Lub oil: 109 m3
- Fresh water: 290 m3
- Industrial fresh water: 510 m3
The tanker will be Det Norske Veritas classified to +1A1 Tanker for Oil Products and Chemical Ship Type 1, ESP, EO, BIS, LCS, MV, NAUT C, NAUTICUS NEWBUILDING.
The main propulsion engine will be an IZAR MAN B&W 6550MC,producing 9,480 kW output at 127rpm and directly coupled to a controllable pitch propeller for a service speed of 15.5 knots at 90% MCR, with a 15% sea condition allowance and a tail shaft generator consumption of 150kW at a 9.25m draft.
he tanks are designed for cargoes of up to 1.8 5t/m3 densities. Cargo handling equipment will comprise 25 submerged hydraulic pumps with a 175 m3/h capacity and three portable pumps with a 300 m3/h capacity. Unloading will be simultaneously served by eight pumps. Tank cleaning will be secured by 50 stationary tank-washing machines. Cargo heating will be achieved by means of double circuit coils inside each tank and dry saturated steam. Inert gas will be provided by a 350 m3/h nitrogen generator with a 97% N2 purity.
A 635 kW variable pitch bow thruster, driven by an electric engine in conjunction with an FSF (Full Spade Flap) rudder, will provide extremely good maneuverability.
