Feature 1
PCTCs take Vinashin to the next level
Höegh Autoliners and Deltamarin have developed a new generation ro-ro
car carrier design with an emphasis on environmental features, to be built
in Vietnam.
S
teel cutting is due to start at Nam Trieu
Shipbuilding Industry Corp on an initial
quartet of new generation ‘Horizon’ pure
car truck carriers for Höegh Autoliners.
The project represents a major step up in
sophistication for Vietnamese shipbuilding.
It follows on from the agreement signed
between Finnish designer Deltamarin and
the Nam Trieu yard covering the detail and
production engineering for the project, in a
contract also including engineering assistance
and production planning support provided by
Deltamarin in Vietnam.
The design effort started with extensive
concept development work through basic The new Höegh Autoliner Horizon class will see first time PCTC-builder Vinashin delivering
