system is topped off with individual independent heating and cooling sys- tems. Additionally, each cargo tank is fitted with three, two or one multi-stage fixed tank cleaning machine. Fully equipped with an integrated navigation bridge, fulfilling the one man bridge notation, the vessels also feature a set of systems that include one voyage data recorder system and one rate of turn indicator (ROTI) system with three repeaters. The bridge system integrates a variety of functions such as digital radars, adaptive track pilot and position sensors. Able to apply a service speed of 15.2 knots, the vessels' structure includes a double skin design and double bottom running the entire length of the cargo section plus the engine room. The dou- ble sides protect the cargo area by way of longitudinal flat bulkheads. Main Particulars Classification ... DNV Length, o.a 533 ft. (162.6 m) Length, b.p 505 ft.

One of the most outstanding features of the series of ships is their capability of simultaneously carrying a wide vari- ety of cargoes. Made possible by an extremely compartmentalized cargo arrangement, the vessels can carry up to 700 different types of cargoes — from fruit juice to propylene oxide — without risk of polluting each other. This flexible cargo section is divided into 36 integral tanks and four deck tanks, designed to carry IMO type 1 and 2 chemicals, plus hazardous and corro- sive cargoes by means of two longitudi- nal bulkheads vertically corrugated. An exception to this would lie in cargo tanks numbered one, two and 13, where the longitudinal bulkhead is arranged in the centerline. Cargo tank capacity amounts to 25,220 cu. m. with payload cargo reach- ing a 24,720 cu. m. total at 98 percent cargo tank capacity. Each tank is served by its own sub- merged hydraulically driven cargo pump and associated piping made of 316L stainless steel. A fully integrated cargo service system controls and mon- itors every operation and includes, in each cargo tank, temperature sensors at three levels, an internal cone antenna for level indication, transmitter gauges, remote pressure sensor of vapor space and independent high level (95 percent), and overfill (98 percent) alarms.
