French liner shipping giant CMA CGM is to deploy the first South Korean-built, LNG-fuelled container vessel writes David Tinsley. The 14,681TEU CMA CGM Tenere is further distinguished by the adoption of a Type B LNG fuel tank, affording capacity for a complete round-trip between eastern Asia and Europe on a single filling.

CMA CGM Tenere is the lead ship in a class of six ordered at Hyundai Samho Heavy Industries by Eastern Pacific Shipping (EPS) of Singapore for charter to the Marseilles-based carrier, which has already shown its commitment to LNG dual-fuel power in container shipping. The series immediately follows on from five 15,128TEU diesel-propelled vessels, of near-identical main dimensions to the nascent sextet, also taken on long-term charter by CMA CGM from Idan Ofer-controlled EPS.

All 11 newbuilds are optimised neo-Panamax boxships, the slightly lower intake of the CMA CGM Tenere-led series reflecting the provision for underdeck LNG fuel storage, notwithstanding the compact nature of Type B prismatic tanks. The merit of the Type B solution is its adaptable geometry, whereby the integrated fuel containment can be moulded to the shape of the hull. Manufactured using 9% nickel steel, the containment in the CMA CGM Tenere provides a volume of 12,000m3.

CMA CGM Tenere is expected to be handed over by Hyundai Samho’s Mokpo yard in July this year. The delivery schedule for the subsequent five ships covers the period from February 2021 to September 2022. The vessel has main dimensions of 366 metres length overall, 51 metres beam, and 16 metres draught. The cellular slot capacity of 14,681TEU in conjunction with an all-up 154,700dwt allows an intake of 10,115TEU loaded boxes on the basis of a 14-tonne homogeneous load factor (HLF). The incorporation of 1,000 reefer sockets affords ample scope for temperature-controlled cargo within the payload mix.

An ME-GI dual-fuel two-stroke engine built under the licence of MAN Energy Solutions at Hyundai’s Ulsan complex was nominated for CMA CGM Tenere and each of her consorts, to ensure transits at up to 22 knots. The selected 11-cylinder model of the G90ME-GI gas-injected design produces 68,640kW at its nominal maximum continuous rating of 68,640kW, although the rating diagram affords owners a wide choice as to specified power and crankshaft speed combinations.

Giving added technical significance to the project, the January shop tests for the first dual-fuel engine marked the debut of MAN’s latest pilot fuel injection technology for dual-fuel running. In this, the pilot booster injection valve (PBIV) employs two different sizes of atomising holes for fuel injection in accordance with the different fuel modes, so as to cut the pilot oil energy fraction. When operating on gas, the use of each array of smaller holes significantly reduces pilot oil consumption to just 1.5%, approximately half of that previously required. In diesel mode, the larger-sized holes are employed.

Besides the PBIV innovation, the Mark II version of the ME-GI engine features a proprietary pump vaporiser unit (PVU), a compact, high-grade pump unit for the supply of LNG.

The five preceding boxships built at Hyundai Samho for EPS and CMA CGM charter are each fitted with an 11G90ME-C diesel plus scrubber plant.

EPS has ordered a further five dual-fuel vessel newbuilds in the 15,000TEU category, a size which is seen by some as a more flexible alternative to, or complementary to, the ultra-large behemoths for mainline trade. It is understood that the contracts have been placed with HSHI parent Hyundai Heavy Industries.

For its part, CMA CGM has given a lead to the industry in blending dual-fuel propulsion technology with the ultra-large containership (ULCS) sphere by way of its incoming generation of Chinese-built 23,000TEU vessels. Each has storage for 18,600m3 of LNG fuel in underdeck membrane tanks of GTT MkIII design.
