The backbone of our efficient and safe fleet is the ten P-MAX tankers. The vessel type is based on Stena’s MAX concept and was developed in response to the need to safely operate in waters and ports with limited depth with substantially more cargo than corresponding vessels of the same size class. To make this possible, the P-MAX tankers are considerably wider, with a uniquely designed hull and a divided stern.
Eight of the tankers in the P-MAX fleet are ice class 1B and two are ice class 1A. Five tankers were converted to IMO3 class after delivery, enabling them to carry vegetable oils and light chemicals in addition to crude oil and light and heavy petroleum products. This flexibility increases the potential for more income days per year.
There are a number of considerable advantages in having ten sister vessels in the fleet. For customers, the ability to hire several vessels of the same type brings increased security, stability and flexibility. For us as a shipping company, development costs can be spread over several vessels. The common design also means that crew can quickly switch from one vessel to another.
As a complement to product tankers, we are also active in the transportation of crude oil. Our presence in the suezmax segment has been represented by the tanker
Stena Supreme since 2012. She is a third-generation fuel-efficient suezmax, which means that her technical equipment and design allow a reduction of 10–15 percent in fuel consumption compared with standard tonnage.
Stena Supreme is employed on the spot market via Stena Sonangol Suezmax Pool, a pool controlled by Stena Bulk and the Angolan state oil company Sonangol. The pool consists of a fleet of about 25 new efficient suezmax tankers.
Stena Image and Stena Important are the two product and chemical tankers that represented our newbuilding program at the end of 2013. The 50,000 dwt vessels, which were ordered in 2012, are part of a series designed with Stena Bulk and Stena Weco, and are being developed in a collaboration between Stena Teknik and Guangzhou Shipyard International in China.
The concept is called IMO2MAX, which indicates that the vessels are IMO2 class. This series is built with a large number of smaller tanks to transport far more loads than traditional product tankers. With a brand new, custom designed hull line, specially designed propellers and a new fuel-efficient main engine, the vessels will be among the most sophisticated on the market – and at the forefront both energy efficiency and cargo flexibility – when they are launched in 2014 and 2015. The intention is to employ the vessels on the spot market through Stena Weco.
