Astilleros Espanoles Delivers Chem Tankers To JO Iankeri

Astilleros Espanoles' Juliana yard in Gijon has delivered to JO

Tankers a pair of stainless steel chemical parcel tankers, dubbed

JO Ask and JO Eik, the former delivered in November 1997, the latter in March 1998.

Both tankers, like sisterships

Botany Triumph and Botany Bay (both delivered in 1997) are of an

Astilleros Espanoles design and feature a double hull which sur- rounds a cargo tank space built mainly of vertically corrugated transverse and longitudinal bulk- heads using duplex-type stainless steel.

Five of the nine transverse divi- sions are of plain sandwich con- struction, forming cofferdams con- nected to the side ballast tanks.

This arrangement reportedly enhances versatility and enables cargoes of different temperatures to be carried in adjacent spaces.

The ships are each powered by a

Manises-MAN B&W 5S50MC main engine, which produces 9,700 bhp at 127 rpm. Driving a CP pro- peller, the ship has a 14.75-knot service speed at 90 percent MCR and a sea margin of 15 percent.

It's well-thought-out hull allows for a fuel consumption of 19 tons/day, a considerable achievement given the ships size, type and speed.

Maneuvering of the vessel is assisted by a CP 635-kW bowthruster and Becker flap-type rudder.

There are a total of 34 tanks of varying capacities: 14 central tanks for IMO I cargoes; and 20 side tanks for IMO II grades.

In all, 800 products with densi- ties up to 2.15 tons/cu.-m. and requiring heating temperatures between 65 and 90 degrees Celcius can be loaded.

The ship has a liquid cargo capac- ity of 19,821-cu.-m.

For discharging cargo, each tank is fitted with a Framo 230-cu.- m./hr. hydraulic submerged pump, seven of which can operate simultaneously for a collective flow of l,610-cu.-m./hr.
