Research Methodology

Multiple input streams — EPC contractor project databases, classification society hull registration records, and utility offtake contract filings — were reconciled against IEA gas market reports and FERC LNG export authorization data. Primary interviews with FLNG project developers, Korean yard procurement officers, and Southeast Asian utility planning directors were cross-validated with secondary sources including IMO marine environment regulations and Petroleum Institute of Mozambique production sharing contract terms. Bottom-up vessel order backlogs and top-down basin reserve estimates were triangulated to anchor capacity forecasts.

Historical commissioning timelines were cross-referenced against expert panel assessments of liquefaction technology maturation and yard slot availability constraints across the projection horizon. Segmentation dimensions modeled include containment technology type, vessel capacity tier, application mode, and end-user contracting structure, with regional regulatory framework clusters treated as scenario inputs. CAGRs were derived from installed base replacement cycles and greenfield development sanctioning rates, incorporating IMO carbon intensity compliance deadlines and EU F-Gas Regulation phase-down schedules as demand-pull factors.

Several conditions sit outside the modeled scope, including unannounced liquefaction process breakthroughs, Korean yard labor disputes, and Mozambique security incidents affecting Rovuma Basin logistics. Forecasts reflect assumptions regarding membrane containment technology retention of newbuild share and sustained Thai-Vietnamese utility procurement for coal substitution. A model refresh is warranted upon material change in IMO enforcement timelines for carbon intensity indicators or Korean industrial policy affecting shipbuilding industry local content requirements.
