Severe foundation scour may occur around monopile foundations of offshore wind turbines due to currents and waves. The so-called p-y curves method is suggested in the existing design recommendations to determine the behavior of monopiles unprotected against scour and the reduction of effective soil stress is accounted for by the extreme scour depth. This conservative design approach does not co...

Age-based analysis of the stoplight parrotfish Sparisoma viride was used to examine whether observed differences in their abundance and size structure among reefs in a cross-shelf portion of the upper Florida Keys could be explained by variation in demographic rates. Annual and daily sagittal otolith increments were enumerated for 176 individuals collected from replicates of reefs in two strata...

In the background of the offshore wind turbine monitoring applications, we analyzed the characteristics of the offshore wind turbine monitor and gave the architecture of the offshore wind turbine monitor system. We designed the system model of blade wear and vibration in offshore wind turbine, and combined with energy efficient data aggregation algorithm based on the specific application to mon...

PROBLEM Tragic marine and offshore accidents have caused serious consequences including loss of lives, loss of property, and damage of the environment. METHOD A proactive, risk-based "goal setting" regime is introduced to the marine and offshore industries to increase the level of safety. DISCUSSION To maximize marine and offshore safety, risks need to be modeled and safety-based decisions ...

In the design of floating systems, three major system components need special attention: the floater, the mooring system, and the riser system. This paper will focus on one the most unique areas in the structural design of these components, namely, the fluid-induced effects on floating structure systems and the associated structural response. Due to the rapid growth in the offshore field, parti...

The distribution of polychaetes associated with an offshore gas platform built on a muddy-sandy bottom in the northern Adriatic Sea was investigated with emphasis on their feeding structure. Polychaete species were collected at different distances from the rig using a Van Veen grab. Assessment of the polychaete community and trophic groups for impacts related to the presence of the platform dem...

The offshore outsourcing (offshoring) posits a high level of risk because of time zone difference, cultural difference and client’s need for more controls over quality and schedule, etc. Knowledge gap between clients and vendors is one of the key challenges for outsourcing success. Offshoring vendors need to continuously acquire external knowledge from clients, assimilate and internalize the ne...
