The estimation of long-term extreme response is a crucial task in the design of marine structures. The target extreme responses are typically defined by annual exceedance probabilities of 10−2 and 10−4. Various approaches can be employed for this

Slamming from steep breaking waves can give high impact loads, both globally and locally. In this study we quantify the difference between slamming loads in long-crested and short-crested seas by performing model tests in 11 different sea states. The

For operations dominated by waves, operational limits are normally expressed in terms of allowable sea state parameters, such as the significant wave height ( H s ) and spectral peak period ( T p ). The allowable sea states need to be assessed in the

In linear air gap analysis of semi-submersibles, the surface elevation is modified by an asymmetry factor to account for the crest-to-trough asymmetry related to wave nonlinearity and the effect of nonlinear diffraction. The asymmetry factor varies w

The safety aspect of the airgap question is discussed. Thereafter uncertainties related to airgap assessments will be discussed both for fixed platforms and semi-submersibles. The various sources are discussed and illustrated with examples. Results a

In order to acquire sufficient simultaneous data to establish joint distributions of waves and currents for design, an extensive measurement programme of simultaneous waves and current profiles has been performed for approximately 5 years at several

Ships may operate in extreme seas, and partial safety factors are incorporated in the corresponding structural design rules in order to ensure adequate safety levels. However, the impact of so-called freak waves on the global loads is still under int

The reliability of an offshore structure is dependent on its response to the extreme wave climate; therefore, an adequate knowledge of the wave climate at a location is a prerequisite during design as well as in marine operations. This study aims to

Short-term predictions of wind and wave properties with a duration of 1–3 days are vital for decision-making during the execution of marine operations. One-step-ahead weather conditions can be accurately predicted via various methods. However, pred
