A Numerical Study on a Flopper Stopper for Leg Positioning of a Jack-Up Barge
Jiang, Zhiyu; Guachamin Acero, Wilson Ivan; Gao, Zhen; Li, Lin (Chapter; Peer reviewed, 2017)Jack-up barges are commonly used for marine operations in the offshore oil and gas, and offshore wind industries. A critical phase within the marine operation activities is the positioning of the jack-up legs onto the ... -
A Systematic Design Approach of Gripper’s Hydraulic System Utilized in Offshore Wind Turbine Monopile Installation
Rasekhi Nejad, Amir; Li, Lin; Guachamin Acero, Wilson Ivan; Moan, Torgeir (Chapter, 2018)This paper presents a systematic approach for designing the hydraulic mechanism as a part of the gripper system employed in offshore wind turbine monopile installation. Traditionally, such equipments used in marine operation ... -
Assessment of Allowable Sea States During Installation of OWT Monopiles with Shallow Penetration in the Seabed
Li, Lin; Guachamin Acero, Wilson Ivan; Gao, Zhen; Moan, Torgeir (Journal article, 2016)Installation of offshore wind turbines (OWTs) requires careful planning to reduce costs and minimize associated risks. The purpose of this paper is to present a method for assessing the allowable sea states for the initial ... -
Assessment of the Dynamic Responses and Allowable Sea States for a Novel Offshore Wind Turbine Tower and Rotor Nacelle Assembly Installation Concept Based on the Inverted Pendulum Principle
Guachamin Acero, Wilson Ivan; Gao, Zhen; Moan, Torgeir (Journal article; Peer reviewed, 2016)This paper presents a numerical study for preliminary assessment of the dynamic responses and allowable sea states for the installation of an offshore wind turbine (OWT) tower and rotor nacelle assembly (RNA) based on a ... -
Methodology for assessment of the allowable sea states during installation of an offshore Wind turbine transition piece structure onto a monopile foundation
Guachamin Acero, Wilson Ivan; Gao, Zhen; Moan, Torgeir (Journal article, 2017)In this paper, a methodology suitable for assessing the allowable sea states for installation of a transition piece (TP) onto a monopile (MP) foundation with focus on the docking operation is proposed. The TP installation ... -
