As a renewable and clean energy source, marine wind power has become an important direction. However, there are few studies on the safety risk assessment of offshore platforms from design stage. Therefore, based project 2000-ton installation platform, characteristics platform during stage have been systematically studied. This paper is to take process as example, devote general method exploring...

The assessment of pile drivability is the premise successful installation, and completely weathered (CW) rock may bring risk refusal. This paper presents a case driving refusal that occurred in CW gneiss layer. physical mechanical properties are analyzed based on results laboratory test, cone penetration test (CPT), standard (SPT). By comparing with those from intact gneiss, layer this study wa...

BACKGROUND Health management tools need to be developed to foster healthy ageing at work and sustain employability of ageing work-forces. The objectives of this study were to 1) perform a needs assessment to identify the needs of offshore workers in the Dutch Continental Shelf with regard to healthy ageing at work and 2) to define suitable program objectives for a future healthy ageing at work ...

Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connect alternative to conventional AC transmission above a certain cable length. This paper presents a new VSC transmission topology for HVDC grid connection of offshore wind farms.

Examination of surficial sediments at 16 stations shows minor, but consistent differences in the numbers and kinds of siliceous microfossils deposited in different regions of Lake Baikal. There is a general north-south decreasing trend in total microfossil abundance on a weight basis. Endemic plankton diatom species are the most abundant component of assemblages at all stations. Chrysophyte cys...

Marine wind energy business competitiveness is strongly related to offshore substructures and their logistics. With the aim of avoiding oil gas methodologies reduce installation costs, some designs make use multi-floater systems linked by cables. Optimization these in search larger operational windows increments likelihood snap-load event occurrence. This work describes analysis cable load duri...

In 2001-2003, >60,000 km of aerial surveys and 7,700 km of vessel surveys were conducted during June to November when critically endangered Korean-Okhotsk or western gray whales (Eschrichtius robustus) were present off the northeast coast of Sakhalin Island, Russia. Results of surveys in all years indicated gray whales occurred in predominantly two areas, (1) adjacent to Piltun Bay, and (2) off...

The world's oil and gas sectors are diverse. They utilize offshore pipes to generate millions of barrels meet global energy demands. In this study we identified the critical buckling load that occurred on a cylinder shell (also known as radial buckling). Offshore pipe design must several criteria, one which is requirement for withstand external hydrostatic pressure seawater. overall calculated ...
