A limiting factor to the increase in the use of LNG fueled ships on a larger scale is the lack of LNG bunkering infrastructure worldwide, with exceptions being northern European countries which have been at the forefront on maritime LNG fuel development, such as Norway and Sweden. DNV GL recently launched a Recommended Practice for authorities, LNG bunker suppliers and ship operators, which provides guidance on how LNG bunkering can be done in safely and efficiently. According to DNV GL, LNG-fuelled ships have logged over 130 ship-years of operation in Norwegian waters. In some parts of the world, operators, suppliers and regulators have gained experience in all aspects of LNG-fuelled ship operations in recent years.

Rolls Royce and DNV engaged in a joint study of different fuel and engine configurations. The vessel selected for this study was the Rolls Royce designed UT 776 PSV. In the study, four alternative power system arrangements were considered, with two gas tank versions. The gen-sets were powered by various sizes of Bergen C-series diesel and gas engines and the dual fuel engine was a commercially available unit. For diesel and hybrids the assumption was that the exausts would have a SCR system giving a constant value of NOx reduction of 75%. In terms of cost, the diesel was the winner in the study as there is the added expense for other solutions of insulated LNG tanks.

With a number of new O&G discoveries popping up nearly continuously in Brazil, both in shallow and deepwater, there has been a significant increase in ROV demand by operators, not only the major players but by all players involved on the Brazilian oil boom. In general the delivery of a complete ROV system may take around nine months, this includes the delivery of key equipment such as heavy duty winches, power and control umbilicals, flotation foam blocks, control modules, tooling kits and backup equipment. Here in Brazil, ROV manufacturers, which are basically all foreign companies with local offices, have been increasing their local stocks of ROV systems.

Brazilian shipyards are trying to become internationally competitive in terms of product quality, pricing and keeping to deadlines. There are presently around 280 units in construction in Brazil, including PSVs, tankers and rigs, with a workforce of around 56 thousand and growing. The shipyards are full to capacity and even though there are over twenty new yards being built, there is still a demand for more. One of the main problems faced by these new yards is to maintain a high quality standard in order to compete with experienced foreign yards. This is no easy feat. However many of these new yards being built have some form of partnership with international shipyards, looking to enter the Brazilian market.

Brasil Supply was launched in 2002 to provide logistics services to offshore operations, technical services of oil, water and gas treatment fluids, and environmental services for the oil and gas industry. Their headquarters is located in the State of Espirito Santo, based in the cities of Anchieta and Cariacica, and they also have offices in the State of Rio de Janeiro, in cities of Rio das Ostras, Rio de Janeiro, and Duque de Caxias. Further south, they also operate in the city of Itajaí, in the State of Santa Catarina, and are developing a significant operation in the Northeast of the country, in association with other major service providers.
