Rolls announced in a statement that it will reduce its number of employees by 400 by the end of next year, on top of 600 job cuts already unveiled in May.
"After many years of strong performance through to 2013, led by good growth in the oil and gas sector, our order book and profitability have been adversely impacted by the sharp and subsequently prolonged drop in the price of oil," said Mikael Makinen, President of Marine at Rolls-Royce.
The latest cutbacks are forecast to generate full-year savings of USD 61 million.
The group's marine division, which employs about 5,800 people in 34 countries, supplies technology and services to customers operating merchant, naval and offshore vessels.
In morning deals, Rolls-Royce shares rallied 2.84 percent to 724.50 pence on London's FTSE 100 index, which was 1.83 percent higher at 6,242.35 points.
