NGL Questions for Profession: State-of-Practice Poll

The following describes a dataset of results from a survey investigating the current state-of-practice in liquefaction evaluations, as described by Ulmer et al. (2026). Practitioners completed the survey during presentations of a Next Generation Liquefaction (NGL) modeling team at local professional society chapters. The survey contained questions on topics within four general categories: site characterization, methods for liquefaction evaluation, approaches to layered and profile-based analyses, and general background information about the survey respondent. The goal of the survey was to better understand the common uses of liquefaction models to maximize the utility of future NGL models and ensure those models are developed in a manner that is comparable with how they will likely be used.

The results indicate a need for continued dialog among practitioners and researchers. Such dialog provides vital information for researchers to consider when developing models that can best support professional practice. NGL has actively sought to facilitate this dialog, which has informed past and ongoing model development efforts.

Responses to the survey questions are shared herein. The poll was opened August 10th, 2024, and is still open and receiving new responses. It is available at https://forms.gle/FrVswJeCnEaFYk11A.
