LR grants AIP for LNG bunker design

LNG Industry,

Lloyd’s Register (LR) has announced that it has granted Approval in Principle (AIP) for 6600 m3 LNG bunker vessel design from Hyundai Mipo Dockyard (HMD). The vessel will be able to serve in both small scale applications and the maximum expected requirements for large ships.

The design is also compliant with the IGC code, and includes two cylindrical Type C tanks, a reliquefaction plant, a loading arm, and high manoeuvrability for safe operations. The design is available in both single screw and twin screw, with different propeller options available.

The EVP of HMD Initial Planning Division, Chang-hyun Yoon, said: “We have steadfastly invested in developing the wide variety of gas ship design not only to respond quickly to the market demand and but also to lead the market. For this reason, we have prepared three prototype of 6600 m3 (single or twin screw) and 15 000 m3 Class dual-fuelled LNG bunkering vessels targeting to operate in Zeebrugge small LNG terminal for LNG fuel in order to develop a global market for the LNG bunkering business.”

Whilst the 6600 m3 design will have two cylindrical tanks and a no-bulbous bow shape, the 15 000 m3 design will have three bi-lobe tanks, as well as a bulbous bow. Both designs are compliant with NOx Tier III at gas mode, and feature a reliquefaction plant (1000 kg/hr), gas combustion unit and different combination of thrusters, flap rudder for better sea-keeping ability in rough sea conditions.

The Gas Technology Manager of LR, Leo Karistios, said: “This HMD design is another significant step in the requirements for safe, efficient gas bunkering worldwide. We are at the start of the LNG bunkering era. The industry is developing technical solutions to support commercial and regulatory requirements. No-one knows at what speed the commercial take-up of gas fuelled shipping will now proceed but concrete technical progress is being made.”

Yoon added: “We have developed small scale LNG carriers ranging from 10 000 m3 to 30 000 m3.

“Because large scale LNG carriers are not appropriate for short voyages and small LNG terminals, small scale carriers could be considered as an alternative. This vessel carries LNG mainly, and also other liquefied gases such as ethylene, ethane, LPG and chemical cargoes could be transported when there is little demand for LNG cargo as owner’s option.”

LR’s Innovation Director, Marine & Offshore, Luis Benito, said: “As LNG-fuelled shipping develops we need to make sure that the risks are being addressed from the very start. The scale of these requirements and need to understand the risks are being supported by our rigorous approaches to identifying and managing risk. Our stakeholders – shipbuilders, ship owners, ports, terminals and regulators – and society – need assurance that those risks are being properly addressed as LNG infrastructure now moves into the big time. This involves meeting international standards and LR has been leading the way in the internationalisation of LNG-fuelled infrastructure.”
