2017年1月1日 · To define accurately the interaction between the Spar and mooring lines, coupled dynamic analyses are appropriate to get responses in deep sea. Considering the coupling effect of the platform and its mooring system, hydrodynamic analyses of a coupled Spar has been carried out in time domain.

2019年12月4日 · A spar is a type of floating oil platform typically used in very deep waters and is named for logs used as buoys in shipping that are moored in place vertically. Spar production platforms have been developed as an alternative to conventional platforms.

What are the main components of the spar platform? The main components of the spar platform discussed are the hull, mooring system, deck, and production equipment. What are the steps involved in constructing the hull?

2012年1月1日 · A “spar” is a term for a long slender pole commonly used in sailing vessels as booms or masts. In the context of this book, spars are floating structures that are characterized by their deep ...

In present study, spar platform are configured as a single fully coupled integrated model in ABAQUS/AQUA. Non-linear dynamic analysis in time domain is performed adopting Newmark-β automatic time incrementation technique. Non-linearities due to geometric, loading and boundary conditions are duly considered.

To date three spar concepts—(1) classic spar (a deep-draft hollow vertical cylinder), (2) truss spar (a combination of relatively shallow-draft hollow cylinder and truss structure with heave plates), and (3) cell spar (a combination of small-diameter tubes

2017年2月17日 · Spar platform is a type of floating structure utilized for oil and gas exploration and production in deep and ultra-deep waters. Coupled analysis in present study considers Spar mooring lines as an integrated system. It incorporates the contribution of …

2017年12月27日 · The spar–mooring–riser system has been analysed to predict system responses induced by wind action under a long crested random wave using finite element approach. Wind load induces a significant shift in the spar position away from its original place in the random sea state in addition to a notable heave motion reduction.

2013年9月2日 · In present study, spar platform are configured as a single fully coupled integrated model in ABAQUS/AQUA. Non-linear dynamic analysis in time domain is performed adopting Newmark-β automatic time incrementation technique. Non-linearities due to geometric, loading and boundary conditions are duly considered.

2016年5月11日 · With the aim of achieving a cost-effective floating platform for offshore wind turbines, a new concept of a monolithic floating spar buoy is hereby presented. The monolithic concrete structure includes both the tower and the floater, built as a continuous single piece.
