Thirteen cargo decks - and an

aerody-namic bow-on the latest Wallenius

car/truck carriers, completed in 1985 by

Hitachi. This Swedish vehicle transport

specialist- one of a number of

compa-nies examined in our Scandinavian

fea-ture - is now considering new tonnage to

ensure a commanding position during

the next decade. See page El39.

Unpowered barges under construction

for Hong Kong interests on one ofthe

berths at Guangzhou Shipyard in the

People's Republic,of China. However,

other more advanced tonnage is also on

order at this interesting yard, as our

report following a recent visit reveals.

Ttie concept of carrying eittier liquid or

break-bull< and unit cargoes in ttie same

hold by utilising reversible hatch covers

has been resurrected, this time by the

Dutch owner Van Nievelt Goudriaan in

association with the Swedish Stora

group. Norrsundet is the first of a series

of 6,000dwt ships from van ver

Giessen-de t^oord and is Giessen-descnbed in our special

feature on The Netherlands beginning on

page £406.

I^ore than 50 cargo ships have been built

at the ti/liho Shipyard in Japan for the

Dutch owner Spliethoff. Pictured here

early this year was one of the latest to be

completed, a 9,600dwt multipurpose

design. See our article on page E421.
