Behind the development of the MAX concept is a need, in terms of transport economy, for vessels capable of operating in waters and ports with draft restrictions and loading substantially more cargo.
Our PMAX tankers are built according to the MAX concept, which was developed together with Stena Bulk and Stena Teknik. The concept is characterised by a high safety approach. The vessels are built with double systems for propulsion and manoeuvring, just like an aircraft. They have two separate engine rooms separated by fireproof and watertight bulkheads. All control systems are separated and each main engine has its own fuel system. Additionally, double rudders and propellers provide better manoeuvrability, which is also a major advantage in terms of efficiency and safety. The double hull goes without saying!
Cutting edge safety
The bridge is designed to provide a 360° view and is equipped with a copilot system, i.e. double control systems. This enhances safety and facilitates training. The vessels’ design and the practice of holding regular drills have resulted in a very low number of accidents on board our vessels.
Outstanding transport efficiency
In addition to safety of the highest class, the P-MAX tankers are characterised by very good transport efficiency and flexibility. Because of their hull design, they are able to transport about 30 percent more cargo on the same draft and with essentially the same fuel consumption as a standard tanker.
Ships in the fleet
The ten P-MAX tankers in the fleet operate all over the world, transporting both light and heavy petroleum products and crude oil. In 2012, Stena President and Stena Perros became the fourth and fifth P-MAX tankers in the fleet to be converted to IMO 3, which means they can also carry vegetable oils. This means increased cargo flexibility and opportunities for more income days per year.
The P-MAX tankers combine transport economy and flexibility with safety of the highest class. In terms of length and draft, these tankers are comparable to a standard type medium range (MR) tanker. Because of their hull design, they are able to transport about 30 percent more cargo than a standard tanker on the same draft, with essentially the same fuel consumption.
The P-MAX concept was developed in cooperation with customers, Stena Bulk and Stena Teknik. Behind the development is a need for vessels able to operate in waters and ports with draft limitations and load substantially more cargo. To make this possible, the P-MAX tankers are considerably wider. The unique design of the hull and the divided stern give both fuel economy and speed characteristics comparable with standard tonnage.
The first P-MAX tanker in the series, Stena Paris, was delivered at the end of 2005. Since then, a further nine PMAX tankers have been delivered and deployed. The last unit in the series, Stena Premium, was delivered in summer 2011.
