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.
