Mariner Class Overview

The Mariner class are the first product tankers to be delivered under the BP Shipping fleet rejuvenation project.

From concept design in 2013 through to delivery in 2016-2017 these vessels are some of the most versatile tankers in the BP Shipping fleet and will be utilised to carry clean products, dirty products and even crude oil on BP business.

The Mariner class are named in honour of the many BP Shipping mariners, seafarers, engineers, officers and cadets in BP Shipping’s proud history and current operations. The individuals that operate our ships are a central part of the BP Shipping strategy and the naming of this class reflects their importance. Certain vessels have names recycled from BP Shipping’s proud 100 year history. This is an honorary tradition; indeed certain Mariner class vessels have had up to four predecessors by the same name.

The Mariner class are a Medium Range ‘MR’ tanker; a size covering 25,000 - 54,999 tonnes deadweight. The larger of this size, an ‘MR2’ are often referred to as a ‘Handymax’ tanker. At 45,999 tonnes deadweight, but with a large cubic capacity optimised for key BP trades, these vessels possess 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 will be amongst the most technologically advanced tankers in the world and the most fuel efficient for their size and power. They were designed with BP Shipping’s core principles in mind and have embedded many operating lessons learned from the BP Shipping fleet and industry best practice. 

Some of the Mariner class have been fitted with a ‘Mewis duct’; an energy efficiency device positioned in front of the propeller. This duct will reduce fuel consumption and subsequently 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.  

The Mariner class were constructed at Hyundai Mipo Dockyard, South Korea, flagged with the Isle of Man (Douglas as port of registry) and classed with Lloyds Register classification society. BP operates these ships with its own crews and provisions.
