ENGINES AND PROPULSION OF TARANTELLA
The Tarantella is powered by a pair of MAK 8M32C four stroke trunk piston medium speed turbocharged diesel engines, each 3,840kW MCR at 600rpm, giving a total output of 7,680kW. The engines are coupled to a single stage vertical offset Metso reduction gearbox (600/105.7rpm) with integral clutches to engines, PTO shaft generator and propeller shaft. The propeller is a KaMeWa 132xF5/4 four-bladed controllable pitch propeller with a 6m diameter.
The cargo vessel can achieve 14.5 knots in laden condition and 15.3 knots in ballast condition. The cruising range is 13,300nm at service speed plus a three-day margin.
The Tarantella has two Sacke / TPK oil fired boilers with two exhaust gas economisers. There is also a shaft generator of 3,200kW connected to either of the main engines (the shaft generator is used in port during cargo operations and at sea), two MAN B&W (Holeby) 5L23/30H engines (682kW at 720rpm), and a 100kW emergency generator.
CARGO PUMPING AND PIPING SYSTEM OF TARANTELLA
The ships’ cargo pumping and piping system allows eight grades of cargo to be loaded or discharged simultaneously by 14 Marflex electrically driven submerged centrifugal pumps. Pumps in tank numbers 3, 4 and 5 P/S have a capacity of 400m³/h each and pumps in tank numbers 1, 2, 6 and 7 P/S have a capacity of 250m³/h each. Maximum discharge rate is 3,500m³/h. Cargo pumps (casing, impellers, pipe stack, etc.) are made of Stainless Steel 316L.
There are 14 Stainless Steel 316L cargo deck heat exchangers. Heating from 44°C to 66°C requires 96 hours. Slop tanks are fitted with Stainless Steel 316L coils that require 24 hours to heat clean slop from 15°C to 60°C.
The tanks have a radar type sounding system, Saab Rosemount, for cargo and pressure type for ballast with remote read out in the cargo control room. There are two fixed Scan-Jet single nozzle machines for hot and cold water washing in each cargo tank. Accommodation is arranged for 24 crew and officers.
