IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Long waves in intermediate depths and their influence on the design of nearshore terminals

ABSTRACT
Over the last decades nearshore cargo terminals have become increasingly more common, for example for the
transportation of LNG. Benefits include easy access to deep water and isolation of potentially dangerous cargo. However,
long waves (infragravity waves) that occur at such exposed locations can lead to excessive vessel motions. Numerical
methods that can calculate long-wave conditions have typically been developed and validated for the shallow coastal
zone, say <10 m depth. Therefore, it is relevant to understand the generation and propagation of long waves at
intermediate depths (15-40 m) and their influence on ships moored nearshore. The Joint Industry Project HAWAII, the
sHAllow WAter InItiative, was started with that goal. The present paper summarises the results obtained from the first two
phases of this initiative (2006-2012), with focus on numerical wave modelling. The main outcome is a design methodology
from the offshore wave conditions to the downtime of a nearshore terminal. Further validation is foreseen in a third phase
of this project (2015-2016), which will include dedicated 3D physical scale model tests in a shallow-water basin facility.
