Abstract Saipem’s life saving rules (LSR) have been well established in Saipem’s processes and procedures for many years. However, the need for an effective campaign to transmit and embed them through the organization was recognized. An internal development team began to regenerate and precisely define ...
Abstract Recently, there has been a drive towards a risk-based approach to plug & abandonment (P&A) design. To apply a risk-based approach for decision-making, i.e. to decide if a P&A design is acceptable or not, risk acceptance criteria have to be established and be approved by authorities. ...
Abstract Geomechanical modelling is widely applied in projecting oil and gas field development. Geomechanics are essential to three basic approaches: supporting oil and gas wells drilling in order to reduce the risk of hole instability (one-dimensional geomechanics). an adequation of effective ...
Abstract The existing literature provides little guidance on the relevance of formation damage or return permeability results obtained from reservoir-conditions core flood testing on sandstone cores with heavy formate fluids. The drilling and completion in open hole of all six production wells in the ...
Abstract Adequate well injectivity is required to successfully inject large volumes of CO2 through a minimum number of wells. Brine vaporization in the wellbore vicinity has been identified as a major CO2 injectivity impairment mechanism especially in deep saline reservoirs. A bundle-of-tubes model ...
Abstract PT Pertamina Hulu Energi Offshore North-West Java (PHE ONWJ) presently operates a fleet of more than 200 fixed offshore platforms and nearly three quarters of these platforms have been in operation for more than 30 years. Under newly implemented Gross Split Production Sharing Contract (PSC) ...
Abstract The use of high-density brines has been always considered as afactor in minimizing formation damage during completion operations. However, these brines can be potentially damaging if it is not well designed. Under high temperature conditions, precipitations may occurcausing a rapid loss innear ...
Abstract The seafloor and near-seafloor in northwest (NW) Borneo contains numerous challenges for the oil and gas industry. In recent geologic history (Miocene and Pliocene), NW Borneo has been very active. The collision of the Borneo plate with continental fragments in the South China Sea resulted ...
ABSTRACT Aquaculture of Atlantic salmon in coastal and offshore locations is an operation intensive industry. This paper gives an overview of the most typical marine operations in the aquaculture of Atlantic salmon. Descriptions of these operations are introduced in the first place, which is followed ...
ABSTRACT In the paper, economic impacts on China's various maritime industries within two years were simulated based on the input-output model (IO model) in economics and input-output tables. As analysis, the sea ice disaster in the winter from 2009 to 2010 caused a total direct economic loss of 6.318 ...
Robot machine capture protein seafood like sea cucumber and seashell is expected to play a great role in food economy improvement and divers protection. In order to realize robot capture, a sea organism absorptive type remotely operated vehicle (ROV) has been designed with the pilot operation and visionbased ...
Mobile ad hoc networks (MANETs) are surrounded by tons of different attacks, each with different behavior and aftermaths. One of the serious attacks that affect the normal working of MANETs is DoS attack. A sort of DoS attack is Jellyfish attack, which is quite hard because of its foraging behavior. ...
Communications are a key part of inshore fisheries and sailing vessels. Especially, it can be regarded as an essential element for the ship's safety. However, unlike terrestrial communication, there is a disadvantage in that fixed terrain cannot be used. Therefore, communications of maritime were common ...
Highly developed drone technology enables the use of drones in a wide variety of areas. However, those drones are mainly used in the unmanned aerial vehicles. We believe that underwater drones will become a big research topic and find a market in the near future. We developed an underwater drone with ...
With the increasing numbers of cars and trips in cites, energy consumption and environmental pollution have become key problems of urban transport. In particular, the increasing use of private cars not only causes more energy consumption and produces more exhaust, but also makes the transportation structure ...
This installment of Notes from the Community covers emerging virtual, augmented, and mixed reality applications; security and privacy issues related to Internet of Things devices; and talking fish.
Aim Perihilar cholangiocarcinoma (PHC) is a challenging disease and requires aggressive surgical treatment in order to achieve curation. The assessment and work-up of patients with presumed PHC is multidisciplinary, complex and requires extensive experience. The aim of this paper is to review current ...
Sperm ultrastructure provides morphological characters useful for understanding phylogeny; no study was available for two basal branches of the Polyopisthocotylea, the Chimaericolidea and Diclybothriidea. We describe here spermiogenesis and sperm in Chimaericola leptogaster (Chimaericolidae) and Rajonchocotyle ...
The loss of previously adaptive traits is typically linked to relaxation in selection, yet the molecular steps leading to such repeated losses are rarely known. Molecular studies of loss have tended to focus on gene sequences alone, but overlooking other aspects of protein expression might underestimate ...
The field of Experimental Mechanics has evolved substantially over the past 100 years. In the early years, the field was primarily comprised of applied physicists, civil engineers, railroad engineers, and mechanical engineers. The field defined itself by those who invented, developed, and refined experimental ...
