National Shipping Company of Saudi Arabia (Bahri), the exclusive oil shipper for Saudi Aramco, more than doubled its first-quarter net profit, according to a statement on Thursday. The company’s profit for the three months to March 31 was 399.0 million riyals ($106.4 million) compared to 195.1 million riyals in the same period a year earlier, it said. It attributed the rise to an increase in its fleet of very large crude carriers to 31 from 17, and full employment of its carriers during the quarter.
