... ABSTRACT For the design of mechanically maintenance-free connections, the preload loss of the bolts must be determined and considered in the design. Since parts in steel construction must often be coated to provide sufficient corrosion protection, an analytical calculation is not possible...

... ABSTRACT In the construction of rubble mound, damages of the rubble mound caused by high waves are the important issues. At construction sites, it is necessary to predict the extent of damage as soon as possible. Therefore, the authors have been developing a numerical analysis method...

... performance of dredge pumps, improve dredging efficiency, and ensure that trailing suction dredgers can still operate normally under large dredging depth. During the construction of dredging vessels, the operating point of the dredge pump also changes with the different soil quality and conveying...

... ABSTRACT An insight is provided into the construction plan and risks associated with the deep trenching of a 30inch diameter natural gas pipeline by water jetting method. Throughout the design and construction process, careful considerations have been given to the project's environmental...

However, harsh climate, lack of logistic and limited experience for mainland and 13 million for ocean. would cause numerous challenges during construction and production. Oil and gas reserves in the Arctic...

... is carried out with the help of the leg structure and the mooring system. The offshore platform adopts the modular construction and assembly method, and moves to the specific sea area by self-propelled, tug-shipment, and other methods. When the service term expires, the platform must be decommissioned...
