“…For the modeling and dynamic analysis of the systems in shipbuilding simulation, a multibody dynamics kernel was developed based on the recursive NewtoneEuler formulations (Shabana, 2005;Featherstone, 2008) in a previous study (Ku et al, 2012;Ku and Ha, 2014). The dynamics of a rigidbody system are described by its equation of motion, which specifies the relationship between the forces that act on the system and the accelerations they produce.…”

This paper suggests an event-based scenario manager capable of creating and editing a scenario for shipbuilding process simulation based on multibody dynamics. To configure various situation in shipyards and easily connect with multibody dynamics, the proposed method has two main concepts: an Actor and an Action List. The Actor represents the anatomic unit of action in the multibody dynamics and can be connected to a specific component of the dynamics kernel such as the body and joint. The user can make a scenario up by combining the actors. The Action List contains information for arranging and executing the actors. Since the shipbuilding process is a kind of event-based sequence, all simulation models were configured using Discrete EVent System Specification (DEVS) formalism. The proposed method was applied to simulations of various operations in shipyards such as lifting and erection of a block and heavy load lifting operation using multiple cranes.

“…Other research has focused on repairing the jack-ups' legs, fixing the corrosion of the bodies and legs and mentioning criteria such as cost and time (Pisano et al , 2019; Guede, 2019; Shazzad Hosaain et al , 2018; Apergis et al , 2017; Kaiser, 2017; Zhao et al , 2014; Kaiser and Snyder, 2013; Xian-Gang and Yong, 2012; Pande et al , 2013; Perrons and Richards, 2013; Cao et al , 2012; Zhang et al , 2012; Kaiser, 2008; Shabakhty et al , 2003; Morandi et al , 2001), while other important criteria are not investigated. In addition, past studies have only touched on the types of shipyards and their equipment (Li et al , 2018; Nam et al , 2017; Ha et al , 2015; Namkug and Ha, 2014; Kaiser and Snyder, 2013; Cao et al , 2012; Celebi and Vardar, 2008; Celebi and Vardar, 2006) failing to survey all required equipment.

Purpose The purpose of this research is to identify the effective criteria and determine the required infrastructure for the repair of drilling rigs. Design/methodology/approach The research was carried out through questionnaires and interviews with experts, including consultants, contractors and operators. A long list of the required infrastructure, dividing into three groups of vital, necessary and support, was prepared and compared with the productivity criteria. Findings The results show that it is better to prepare and upgrade the vital, necessary and supportive equipment in the shipyards, including refrigeration workshop, cofferdam for repairing spudcans and residential and educational places. Practical implications These results are helpful for the industries working on jack-ups and the countries having similar conditions to enable them to use their assets in an optimum way. Originality/value Oil drilling rigs' repair and maintenance (R&M) services are essential because of affecting the economy. Furthermore, about 25% of Iran’s oil drilling rigs are jack-up, needing overhauls every five years. Other research has investigated how to repair jack-ups, their incidents, their R&M industry market and, only in some cases mentioned, cost and time criteria. Therefore, it is necessary to identify the criteria and study the infrastructures in the shipyards.

A multibody system including a drilling riser system, tensioners and a floating platform is key equipment for offshore oil and gas drilling. Most of the previous studies only focus on the drilling riser system rather than the multibody system. Mechanical characteristics of the deepwater drilling riser system cannot be analyzed accurately in a simplified model. Therefore, a three-dimensional multibody analysis program is developed. The static and dynamic characteristics of the deepwater drilling riser system under different platform motions are analyzed based on the developed program. The results show that the static displacement of the riser system with tensioners is smaller than that without tensioners, which means the tensioners can suppress the deformation of the riser system. Under surge and sway motions of the platform, the dynamic displacement of the riser system with tensioners is also smaller than that without tensioners due to the tensioner suppression effect. Besides, the heave motion induces a uniform axial vibration of the riser system, while roll and pitch motions excite the riser system to vibrate laterally. Compared with the stress amplitude due to surge and sway motions, the stress amplitude of the riser system due to heave, roll and pitch motions is relatively small but cannot be neglected.
