BRINGING THE
FUTURE CLOSER

WHAT WE ARE UP TO

TAKE A GLIMPSE AT OUR PROJECTS

Below is a selection of the projects Stena Teknik has developed and completed – as well as selected ongoing projects and concepts.

STENA ELEKTRA

NEW CONCEPT

At Stena Teknik, we encourage innovative ideas and sustainable solutions. One of our concepts in development started out as a half measure. A hybrid vessel with a supporting battery pack, like on a modern hybrid car, that enables the engines to always run on their optimum rate. But why not replace the entire engine system with batteries? A clean solution – both in the engine room, and for the environment.

Stena Elektra is intended to operate on the route between Göteborg and Fredrikshavn, solely powered by electricity. As of today, the concept is not yet profitable, but with the rapid increase of capacity and descending prices of batteries, it’s only a matter of time.

“We started to look into a hybrid solution vessel for our Gothenburg-Fredrikshavn route, but then got the idea to design an all-electric system”, says Henrik Nordhammar at Stena Teknik. “You realize that by removing the fuel engines, you can also remove the fuel tanks, the piping, purifiers, heaters and exhaust gas systems. You basically don’t need an engine room, just space for the batteries.”

The vessel is still on a concept stage, and there are several challenges to overcome before it can be realized, like how to recharge the batteries with 50 MWh of electricity during the 90 minutes in port.



STENA IMOIIMAX

IN PROGRESS

Stena Teknik have together with Guangzhou Shipyard in China succeeded after extensive development and towing tank tests obtained a design that is probably the most energy efficient Eco MR Tanker existing today. Completely new and revolutionar​y hull lines together with specially designed propeller, rudders, engines, exhaust gas energy recovery and onboard systems will reduce the overall energy consumption to a minimum.​



ROPAX 4050 LANEMETRES

COMPLETED

Stena RoRo’s two RoPax vessels, built at Samsung Heavy Industries, South Korea. These vessels are a developed version of the successful Stena Trader/Stena Transporter vessels that operates for Stena Line between Hoek van Holland and Harwich. The arrangement features high cargo capacity and excellent operational efficiency. Stena Teknik supported Stena RoRo in this project by providing a Project Manager and general technology support, mainly within structure and hydrodynamic issues. First ship was delivered in Q1-12.



SUEZMAX TANKERS 154.000DWT

COMPLETED

Stena Suezmax tankers were built at Samsung Heavy Industries, South Korea. When developing the design of these ships the focus was to optimize the fuel consumption. By investing in bigger engine, larger propeller, etc the reduction is estimated to be sensational, about 10%, in service condition. First ship was delivered in Q3-2011.



STENA DRILLMAX ICE

COMPLETED

Stena Drilling’s 4 drillships, built at Samsung Heavy Industries, South Korea. The first three are operating world-wide as they are designed for deep water and harsh environment. Stena DrillMAX ICE (no 4) is constructed for operation in the ice covered water of the Arctic. The hull strength has been designed to PC4 notation and the rest of the ship to PC6. The transit and drilling operation has to be supported by ice breakers carrying out ice management to get a controlled environment. Delivered in Q1-12.



STENA DRILLMAX

COMPLETED

Oil and gas prospecting in ultra deep waters. The DrillMAX vessels are the sixth generation of drillships. Stena’s Drill-MAX fleet are built at Samsung Heavy Industries’ shipyard in South Korea. The DrillMAX is a drillship with dynamic positioning designed to operate all the year round in ultra deep waters worldwide, including harsh environment of the North Sea.



STENA P-MAX

COMPLETED

First-class oil transport. The P-MAX tankers combine transport economy and flexibility with exceptionally high safety and were built at Brodosplit Shipyard in Croatia. Thanks to the hull design, these tankers are able to transport about 30% more cargo at no appreciable extra cost. They are designed to transport both crude oil and refined petroleum products.



STENA C-MAX

COMPLETED

Navigating in narrow waters. The C-MAX tankers were developed for operation in shallow and narrow waters where other vessels are normally unable to sail. The C-MAX tankers were delivered from the shipyard in Gdynia, Poland, in 2002. The first of these tankers were built to transport refined products in the West Indies where the demands on transport safety and cargo flexibility are high. They are able to transport up to 17 different types of refined and unrefined petroleum products in separate tanks.



STENA V-MAX

COMPLETED

Superior cargo capacity on restricted draught.The V-MAX tankers were the first to be built according to the MAX concept. They were built by Hyundai Heavy Industries in South Korea and delivered in 2001. Their design has increased their cargo intake by 20-40% compared with a conventional Very Large Crude Carriers (VLCC) and by 70-100% compared with a so-called Suezmax tanker.
