Astromaritima Navegação, known as the largest Brazilian offshore vessels' owner and operator, plans to upgrade three of its 180 ft. (54.8 m) OSV's for an approximate cost of $4.5 million.
The first two of the vessel trio will receive a third engine and a second bowthruster to increase overall installed potency to 4,300-bhp. The remaining OSV will house two new engines
, with at least 2,200-bhp each, as well as a second bowthruster and midship section measuring 29.5 ft. (9 m).
Financed by Brazilian development bank, BNDES, the modernization process will be partially executed by Astromaritima's drydock
, while Promar Shipyards will provide related services from its Guanabara Bay facilities in Rio de Janeiro.
