Abstract

Abstract:

Pendulous installation method is applied to the installation of subsea facilities, which has low requirement for a ship and is conveninent to operate. We employ nonlinear coupling time domain analysis of hull, sling and manifold to construct a hydrodynamic calculation model for ship installation and a Morison model for the installation of sling and submarine facilities. Checking convergence precision, selecting calculation parameters and performing numerical analysis for the entry water process of deepwater manifold have some reference value for domestic deepwater engineering.

Key words: pendulous installation method, nonlinear coupling, time domain analysis, numerical simulation
