Mariner Class

The Mariner class were among the first product tankers to be delivered under the 2016-17 BP Shipping fleet rejuvenation project. They carry clean products, dirty products and crude oil on BP business.

Named in honour of the many BP Shipping mariners, seafarers, engineers, officers and cadets in BP Shipping’s proud history, the Mariner class have names which have been handed down through BP Shipping’s proud 100 year history. This is  a long-standing tradition; indeed certain Mariner class vessels have had up to four predecessors by the same name.


The Mariner class are medium range tankers at 25,000 - 54,999 tonnes deadweight. The larger of this size are often referred to as ‘Handymax’ tankers. At 45,999 tonnes deadweight, but with a large cubic capacity optimized for key BP trades, these vessels have the flexibility to adapt to multiple worldwide trades, clean or dirty, long haul or short haul, east and west hemisphere. 


At the time of delivery, the Mariner class were among the most technologically-advanced tankers in the world and the most fuel-efficient for their size and power.

Some were fitted with a ‘Mewis duct’, an energy efficiency device positioned in front of the propeller that reduces fuel consumption and emissions by up to 7%. All of the Mariner class are IMO 3 capable allowing the carriage of certain bio fuels, vegetable oils and benign chemicals. 


BP operates these ships with its own crews.
