This paper deals with new challenges regarding power quality in ship technology resulting from the novelisation and implementation of IACS (International Association Classification Societies) rules requirements. These rules, known as E24 2016/2018, address harmonic distortion for electrical distribution systems, including filters. The reasons legislative changes based on a short overview qualit...

Abstract The technological development ongoing in the maritime industry is making ground for remotely and even autonomously operated vessels future. This a result of increased data collection, processing inter-connectivity capabilities. working towards safety, improved efficiency ship’s operation, environmental performance more cost-effective shipping. New technologies are developed order to re...

Nowadays, the floating production storage and offload system (FPSO) is one of most common platform types for offshore oil production. The traditional arrangement stiffened panels creates obstacles automated cleaning inspections by remote devices. This paper summarizes results an initial study design construction FPSO hulls with SPS in order to overcome this problem. main goal have walls bottom ...

Free-span occurs normally in a pipeline at uneven seabed, dynamic seabed and pipeline crossing. Free spanning in pipeline causes Vortex Induced Vibration (VIV) fatigue, fracture and bursting. In this paper, a pipeline located in South Pars Gas Field is assessed against local buckling and VIV fatigue using probability of failure theory based on the recommended methodology by Det Norske Veritas (...

Abstract The aim of this work was to examine uniaxial, torsion, and multi-axial fatigue characteristics ER100S-1 low carbon steel specimens fabricated with wire arc additive manufacturing (WAAM) technique, a subcategory directed energy deposition (DED). Two distinct specimen orientations were tested—vertical horizontal, extracted perpendicular parallel the WAAM deposited layers, respectively. F...

OCI Nitrogen seeks to gain knowledge of (leading) indicators regarding the process safety performance their ammonia production process. The current research determines most dangerous equipment by calculating effects resulting from a loss containment using DNV GL's Phast™ dispersion model. In this paper, flammable and toxic release main an plant have been calculated. Such encompassing approach, ...
