Official Discusser: Prof. Jorgen Amdahl

Concern for accidental limit states (ALS) of ships and offshore structures and their structural components under accidental conditions. Types of accidents considered shall include collision, grounding, dropped objects, explosion, and fire. Attention shall be given to hazard identification, accidental loads and nonlinear structural consequences including residual strength together with related risks. Uncertainties in ALS models for design shall be highlighted. Consideration shall be given to the practical application of methods and to the development of ISSC guidance for quantitative assessment and management of accidental risks.

Chair: Daniele Dessi
Liaison: P. Kaeding
Official Discusser: Prof. Toichi Fukasawa

Concern for advances in structural model testing and full scale experimentation and in-service monitoring and their role in the design, construction, inspection and maintenance of ship and offshore structures. This shall include new developments in: best practice and uncertainty analysis; experimental techniques; full field imaging and sensor systems; big data applications for ship and offshore structures; and correlation between model, full-scale and numerical datasets.

Chair: Lennart Josefson
Liaison: Y. Chen
Official Discusser: Stephane Paboeuf

The committee shall give an overview about new developments in the field of ship and offshore materials and fabrication techniques with a focus on trends which are highly relevant for practical applications in the industry in the recent and coming years. Particular emphasis shall be given to the impact of welding and corrosion protection techniques for structural performance, and on the development of lighter structures.

Chair: Gao Zhen
Liaison: X. Wang
Official Discusser: Dr. Dominique Roddier

Concern for load analysis and structural design of offshore renewable energy devices. Attention shall be given to the interaction between the load and structural response of fixed and floating installations taking due consideration of the stochastic nature of the ocean environment. Aspects related to prototype testing, certification, marine operations and levelized cost of energy shall be considered.

Chair: Darren Truelock
Liaison: S. Ferraris
Official Discusser: Derek Novak

Concern for structural challenges of non-conventional, special surface craft, including uncertainties in established design methods and modelling techniques. Particular attention shall be given to mega yachts, naval craft, offshore service vessels and work boats, which can be characterized by particular structural configurations and materials (wide openings, large unsupported structures, unconventionally shaped superstructures, etc.) and/or are to sustain specific loading conditions (harsh environment, severe cyclic loads or extreme operational ones).

Chair: Soren Ehlers
Liaison: M. Samuelides
Official Discusser: Prof. Pentti Kujala

Concern for development of technology of particular relevance for the safety of ships and offshore structures in Arctic regions and ice infested waters. This includes the assessment of methods for calculating loads from sea ice and icebergs, and mitigation of their effects. On this basis, principles and methods for the safety design of ships and fixed and floating structures shall be considered. Recommendations shall also be made regarding priorities for research programmes and efficient implementation of new knowledge and tools.

Chair: Paul Hess
Liaison: A. Shenoi
Official Discusser: Prof. Dan M. Frangopol

Concern for the structural longevity of ship, offshore and other marine structures. This shall include diagnosis and prognosis of structural health, prevention of structural failures such as corrosion and fatigue, and structural rehabilitation. The focus shall be on methodologies translating monitoring data into operational and life-cycle management advice. The research and development in passive, latent and active systems including their sensors and actuators shall be addressed.

Chair: Menglan Duan
Liaison: S. Estefen
Official Discusser: Dr. Frank Lim

Concern for the safety and reliability of subsea production systems for oil and gas offshore. This shall include subsea equipments for production and processing, flowlines and risers, with emphasis to design, fabrication, qualification, installation, inspection, maintenance, repair and decommissioning. Structural design for flow assurance and safe underwater operations shall be considered.
