Abstract Structural failures of offshore wind turbine substructures might be less likely than other equipment the generator but pose a high risk due to possibility catastrophic consequences. Significant costs are linked operations like inspections and maintenance, thus remote monitoring shows promise for cost-efficient structural integrity management. This work is aimed investigate feasibility ...

Offshore oil and gas industry is blooming up towards the deep-water region of ocean deposit. Far off the continental shelf, the traditional jacket type fixed platform and bottom supported compliant platform are not suited to be economic offshore structure in deep water oil and gas exploration. Floating Spar platform is essentially most economic and efficient in these sea states. In the present ...

Full-scale tests were performed to study the penetration resistance of steel plates (skirts), which are common foundation elements jacket offshore wind structures. Penetration is well-studied in clays and sands, but there limited information on gravels, typically used as scour protection critical like substations. Direct extrapolation sands not possible because grain-size effect. Two plate thic...

The halo body jacket and plaster Minerva body jacket have been the preferred orthoses when maximal stabilization of the cervical spine is required. This report identifies some disadvantages of these orthoses, introduces the thermoplastic Minerva body jacket (TMBJ), and discusses its advantages in the rehabilitation of patients with cervical spine instability. A preliminary roentgenographic stud...

OBJECTIVES To laparoscopically compare the effectiveness of 2 cooling devices for renal hypothermia and investigate the feasibility of laparoscopic orthotopic kidney transplant using a pig model. MATERIALS AND METHODS Eight pigs were divided into 2 groups of 4 animals each. Laparoscopic nephrectomy and autotransplant were performed first on only the right kidney. One week later, these procedu...

The RONDAN jacket support clamp and jacket transport sled are inexpensive, relatively easily fabricated tools which have proved invaluable for the field collection of large vertebrate specimens. Although there are some complicating factors, both of these tools have been used with great success to safely collect and transport numerous Jurassic dinosaur bones.

This paper investigates from a structural reliability assessment (SRA) perspective the fatigue using S-N curve approach compared with fracture mechanics (FM) for typical welded offshore wind turbine (OWT) jacket support structure. A non-intrusive formulation was developed an OWT structure in 50 m deep water, consisting of sequence steps. First, stochastic parametric 3D (three-dimensional) Finit...
