HAPAG-LLOYD first-ever conversion of large container ship to LNG

 

.

Hamburg, March 12, 2019 – The Hamburg-based engineering company TECHNOLOG services GmbH has received an order from HAPAG-LLOYD to carry out the world’s first conversion of a large container ship to use liquified natural gas (LNG) propulsion.

TECHNOLOG has already been involved in the pilot project by providing technical consulting services during the preliminary phase of the conversion, such as by coordinating the market-leading system suppliers and selecting the shipyard in which the conversion will be carried out. The Hamburg-based LNG specialists will now also assume responsibility for coming up with the overall conversion design for the Chinese Hudong-Zhonghua Shipbuilding group along with the executing repair yard Huarun Dadong Dockyard (HRDD).

„With our design, we have succeeded in intelligently combining the existing design with additional components, systems and software,” says Hans-Jürgen Voigt, Managing Director of TECHNOLOG. “By allowing LNG to be used as a fuel, this retrofitting will help us to achieve the optimum balance of environmental protection, sustainability and economically efficient operation in the shipping industry. As a demonstrator vessel, the SAJIR will set the benchmark for future conversions of vessels of this size.”

All designs, documents and certificates relevant for the DNV GL classification society will be realised in very close coordination with HAPAG-LLOYD’s Fleet Management or prepared by TECHNOLOG for the conversion yard in the form of specification drawings and production documents.

“With the unprecedented pilot of converting the SAJIR, we hope to pave the way for large ships to be retrofitted to use this alternative fuel,” says Richard von Berlepsch, Managing Director Fleet Management at HAPAG-LLOYD. “Working with TECHNOLOG, we will have a reliable partner at our side for this project.”

A construction supervision team with members from both TECHNOLOG and HAPAG-LLOYD will be on-site at the Shanghai shipyard to monitor the prefabrication of the LNG tanks and the cryogenic gas components as well as the subsequent ship conversion itself.

The demanding and pioneering project that TECHNOLOG is assuming leadership of will set the standard for future conversions of this type in addition to being prepared and executed in a hitherto atypical constellation of a consortium of suppliers. The consortium will be made up of the main suppliers of the components needed for the conversion as well as the Huarun Dadong Dockyard Co., Ltd. repair yard in Shanghai.

The SAJIR, a 15,000 TEU vessel, is already one of the most energy-efficient ships in the world. As the lead ship in a HAPAG-LLOYD class with 10 sister vessels, the SAJIR will now be converted into an “LNG demonstrator vessel“ in order to showcase the potential that this alternative fuel holds for the international shipping industry.

The use of LNG in large container ships such as these has the potential to almost completely (more than 90 percent) eliminate emissions of sulphur and diesel particulate matter in their exhaust gases as well as to reduce emissions of both nitrogen oxides and carbon dioxide by around a third.

By using LNG, the SAJIR can lower its CO2 emissions by 31 percent and thereby have emissions at only half the limit to be introduced in 2025, with the international Energy Efficiency Design Index (EEDI) as the yardstick.
