Optimization of Integrated Template Structures for Arctic Subsea-Production Systems
This paper analyzes the various selection methods of integrated template structures (ITSs) for use in the Arctic environment. First, an analysis of several actual projects is carried out, with the specific features of each described thoroughly. An important part of the work is devoted to the requirements of ITSs conceived in relevant NORSOK (Norsk Sokkels Konkuranseposisjon), International Organization for Standardization (ISO), and DNV (Det Norske Veritas) standards. The main elements of subsea production modules are examined in this work, along with their specific characteristics and components.
Operation and installation of subsea modules in the Barents Sea are also analyzed in this paper. Four scenarios, with differing numbers of ITSs (two, three, four, and six) and differing quantities of well slots in each, are considered. For each scenario, a study of related marine operations (required for installation) is performed, and a program for installation-cost estimates is developed, resulting in the determination of an optimal design for the ITSs. Various parameters affecting the cost of subsea infrastructure are analyzed and studied from different perspectives (e.g., geometrical well-pattern systems, distance between drilling slots, drilling and construction costs). Risk analyses of the threats and consequences involved in the process are performed, and risk-assessment matrices and mitigation actions are established. As a result, a model for selecting an optimal ITS for the Arctic/Sub-Arctic region is created.
A Model for Evaluating Inlet Systems to Gas/Liquid Separators
Learn about the guidelines for early stages of projects and a method for evaluating the effect of inlet piping and inlet devices on gas/liquid separator performance. The described methods give designers useful tools to evaluate the adequacy of a proposed design.
Kreuz Subsea Mobilizes New-Built Vessel, Enters Into JV in Brunei
Kreuz Subsea mobilized the Kreuz Challenger, a diving support vessel, as part of its 7-year contract with Brunei Shell Petroleum Company. The contract runs until 2022 and includes inspection, repair, and maintenance services to be carried out on offshore oil and gas structures.
Video: Early-Stage AUVs Set To Launch in North Sea Facilities Inspection Trials
Advanced AUVs with early-stage technologies for live streaming, ultrasonic testing, and 3D laser scanning are set to enter inspection trials on North Sea facilities. The aim is to reduce facilities inspection costs by 50%.
