Lloyd's Register (LR) has granted an approval in principle (AIP) to a team formed by Daewoo Shipbuilding and Marine Engineering (DSME) and MAN Energy Solutions for an ammonia-fueled 23,000TEU containership design.
As part of the joint development programme (JDP), DSME generated the basic design of the ammonia propulsion system and MAN Energy Solutions was responsible for the development and specifications of the ammonia dual fuel propulsion engine.
LR's role was to review the suitability and risks of the design. The role involved a hazard identification (HAZID) workshop, a hazard and operability (HAZOP) analysis workshop, and a design review in accordance with the approval of risk-based design (ARBD) process, which then led to the AIP.
LR's AIP certification is the first phase of the JDP. The second phase will involve further development of the design for meeting market demand in terms of commercial viability as well as technical and safety maturity.
The ammonia-fuelled containership is expected to be commercialised by 2025.
