Totally proper forcing and the Moore–Mrówka problem

Fundamenta Mathematicae, 2003
Summary: We describe a totally proper notion of forcing that can be used to shoot uncountable free sequences through certain countably compact non-compact spaces. This is almost (but not quite!) enough to produce a model of \(\text{ZFC}+\text{CH}\) in which countably tight compact spaces are sequential -- we still do not know if the notion of forcing ...

Model Study of Mooring Forces of Docked Ship

Journal of the Waterways and Harbors Division, 1959
Laboratory data presented on forces induced by water gravity waves in camels and mooring lines of Liberty Ship, moored alongside dock, for waves up to 5 ft in height and with periods up to 120 sec; it was not possible to obtain simple natural periods of surge, sway, etc for this particular mooring arrangement as one motion induced another.

Investigation Into Scale Effects On Motions And Mooring Forces Of A Turret-Moored Tanker

Offshore Technology Conference, 1994
ABSTRACT A loaded 200 kDWT tanker moored by means of an internal bow-turret is exposed to survival conditions (colinearly directed irregular waves and wind). The water depth amounts to 82.5 m and the turret mooring system consists of 6 equally spaced chains.

Characteristic of tsunami force acting on shelter with mooring

Applied Ocean Research, 2017
Abstract Tsunami shelter has been designed and built as a refuges in case tsunami occurs. In recent year, different kinds of tsunami shelter have been proposed and developed, which is either a building type or a floating one. The main purpose of this research is to propose a new type of tsunami shelter with elastic mooring in comparison with a fixed ...

Numerical Simulations of Ice Forces on Moored and Thruster-Assisted Drillships

OTC Arctic Technology Conference, 2014
Abstract The present work examines the loads on moored/DP-assisted drillships and their responses in managed pack ice. Numerical simulations are used to determine deformations and stresses within the ice cover and the movements of the vessel.

Potential Wave Forces on a Moored Vertical Cylinder

1990
In this chapter, analytical expressions are derived for the linear and quadratic potential wave forces acting on a moored, vertical, and surface-piercing cylinder. The forces are described by a second order Volterra series with the linear wave elevation as the input function.

Analytical Determination of Ship Motions and Mooring Forces

Offshore Technology Conference, 1974
ABSTRACT This paper describes a computer program which calculates the three translator motions heave, surge and sway - and the three rotary motions - roll, pitch and yaw - of a ship, represented by a rectangular block, moored in regular waves of given height and period approaching from an arbitrary direction ...

Design of Drilled Shafts for Unusual High Mooring Forces

2018
Most drilled shafts are treated as columns or beam-columns subjected to the vertical compression load of buildings or bridges. In the case presented in this paper, drilled shafts were used to take lateral and uplift forces, and were treated as circular flexural composite members.

Forces Related to Motions of Moored Ships/ Analytical Methods of Moored Ship Motions

1988
The behaviour of moored ships in harbours, coastal areas or offshore is extremely complex, due to nonlinearities and dynamic effects. It is of vital importance to have methods available by which the behaviour of the moored ship can be predicted in the design stage, in order to determine the extreme loads in the worst conditions and to assess the ...
