The Chinese-owned Tianjin Desail is working with DNV GL to develop a new liftboat design for offshore construction, accommodation, and maintenance, which will have 90% local content, the companies said on 21 August.
This collaboration comes following the agreement between DNV GL and Tianjin Desail for the classification of two 350 ft (106 m) self-elevating construction and accommodation units to explore international market for Chinese-designed and made offshore equipment.
The two newbuildings will be built at Xiamen Shipbuilding Industry.
According to the general manager of Tianjin Desail, Su Shilin, the liftboats will have the capability for deployment in water depths from 60 to 80 m.
The units consist of a barge-shaped hull with four triangular lattice legs, each fitted with a spud can at their lower ends.
A work deck top side arrangement will be developed for each unit including pedestals for main and auxiliary cranes and living quarters with a helicopter deck on top.
Each unit is equipped with dynamic positioning system for field transit and manoeuvring.
“This new type of self-elevating units is the first to be built to DNV GL Class in China,” said Johan Gärdin, DNV GL regional offshore manager in Greater China.
