The Second Marine Operations Specialty Symposium (MOSS 2012), held during 6 to 8 August 2012, is organized by the Centre for Offshore Research & Engineering (CORE) in the National University of Singapore (NUS), and supported by the ASME International Petroleum Technology Institute. The first Symposium was held in NUS during 5 to 7 March 2008. The need for continuing such a specialty symposium is demonstrated by the many noteworthy offshore facilities installed and completed in both shallow and deepwater fields worldwide. We also received significant guidance and support from members of the International Organising Committee, recognized experts in various aspects of marine operations, to hold another marine operations conference. The overwhelming responses to our call for papers underscored the need for the second symposium, and we are pleased to include the selected papers in the MOSS proceedings.

The contributing authors are from key oil & gas companies, consultants, contractors, classification societies, universities and research institutes. The topics covered include Standard on Marine Operations, Offshore Construction Vessels, Dynamic Positioning, Challenges of Ultra-large & Ultra-deep Systems, Lifting Operations, Float-over Operations, Side-by-Side Operations, Installation of Jackets and Foundation, Installation of Subsea Equipment, Anchor Handling Operations and Pipelines.

We like to record our sincere appreciation for the financial support from our sponsors: McDermott International, EMAS AMC, WorleyParsons INTECSEA and Keppel Offshore & Marine Technology Centre. The strong support of the Lloyd’s Register Educational Trust (LRET) towards the LRET Professorship and R&D Programme in NUS is gratefully acknowledged. The Office of Professional Engineering & Executive Education in NUS Faculty of Engineering has ably provided the secretarial and operations support for MOSS. In particular, we like to thank Mr. Kok Keong Cheah for his significant contributions.

We will be pleased to receive input and feedback from readers with regards to the presented papers, and plans for future activities and events in marine operations.

Thank you and best wishes.
