Korean Yards and LR collaborate

Troubled Korean shipyards Hyundai Heavy Industries (HHI) and Hyundai Mipo Dockyard (HMD) aim to intensify their efforts for market share in green shipping orders through a collaboration with Lloyds Register.

The classification society and the shipyards have signed a joint development project (JDP) to produce a ship-to-ship LNG bunkering compatibility study. »This will comprehensively review the design requirements between 6.6K LNG bunkering ships and 14K TEU LNG-fuelled container ships with the goal of verifying safe ship-to-ship LNG bunkering«, the partner said in a statement.

The study would aim to help all stakeholders with interest in LNG as fuel to envisage a clear picture of possible options for LNG supply infrastructure. It follows LR’s previous work with LNG-fuelled ship projects with HHI and LNG bunkering ships with HMD.

»There is no existing standards or guidelines that cover the design and procedure for safe ship-to-ship LNG bunkering. However, this method of bunkering is preferable for many port authorities for safe and effective port operation and also preferable for ship operators due to cost-effective convenience«, it was added.

The main objective of the JDP is to investigate the practicability of the LNG supply model by ship-to-ship between the typical size of 6.6K LNG bunkering ships and ultra-large container ships (ULCS). These designs have been reviewed and developed based on the LNG-fuelled system, and accordingly, the study will evaluate the right direction for LNG supply infrastructure.

LR has already developed a checklist for the design of LNG bunkering vessels and LNG receiving vessels for this JDP that summarises the risks related to ship-to-ship LNG bunkering, and also suggests design aspects which are not covered by legislation but are useful in understanding the characteristics of LNG-fuelled/LNG bunkering ships at the design stage.

This checklist would both HHI and HMD provide with a chance to comprehensively review their design by, not only mandatory rules requirements, but also the prospective guidelines in order to identify the scope for further improvements in their design in line with their ships’ operating profiles.

Jin-Tae Lee, Ph.D, LR’s Korea Chief Representative & Marine Manager, said: »Following recent developments in major ports towards a cleaner shipping industry, stakeholders will show interest in the advantages of LNG as fuel. However, the uncertainty associated with LNG supply infrastructure is still an influential factor in determining the profitability of a LNG-fuelled vessel. Stakeholders need to have a clear understanding of the benefits and challenges.«

Chang-hyun Yoon, EVP of HMD Initial Planning Division added: »After having developed LNG bunkering ships with LR, we are expecting to comprehensively review our design in order to identify the key points for further improvements suited for the clients’ interests and demands through this JDP, thus trying to mitigate or minimise any potential issues which the operators can encounter during real operational situations.«

LR, HHI and HMD plan to expand the study for other ship types, including VLCC and Suezmax, following the completion of ULCS study.
