Caterpillar launched the Cat offshore power generation module, a turnkey scalable, single lift, modular power plant product. The unit offers full integration into a floating, production, storage, and offloading (FPSO) vessel or a fixed production platform's structural design. It was designed specifically to meet the needs of FPSO and fixed production platform's main power applications in cases where a gas turbine was not ideal. Available from 4 MW to 17.3 MW per module, the unit runs on liquid, diesel, crude, and heavy fuel oil or gas. It also runs in dual fuel mode and meets current and future emission regulations to maximize flexibility and reduce operating costs.
Production and drilling activities in offshore installation are one of the most necessary activities of human society. To drill a subsea well and raise the crude oil to a platform, by itself, presents a series of risks. Associated with this activity, when the crude oil reaches the topside of the platform, there are a number of operations that prepare the oil and gas to be exported to land by pipelines or oil tanker vessels, which involves equipment and process that take high temperatures, high pressure and high flow rates. Understanding the dynamics of the factors that can affect the interaction of operators with all these offshore complex systems is critical, because the loss of control of these systems can cause serious accidents, resulting in injuries to workers, environmental damage, loss of production and geopolitical crises. Accidents in the oil and gas offshore installations, such as drilling rigs and FPSOs, can have tragic consequences and all efforts should be targeted to prevent its recurrence. Therefore, from the perspective of current technological developments, it is essential to consider the influence of Human Factors in the risk management of offshore industrial plants.
The objective of this paper is to explore the benefits of using the Interactive Epoch-Era Analysis (IEEA) methodology for evaluating architectural changes in a trade space exploration study. In this paper a subsea tieback offshore Brazil will be used as reference case to investigate this premise from a full field development perspective.
An automated concept exploration tool is employed. It applies meta-heuristics to generate different offshore facilities concepts with varying building blocks. The interaction between reservoir behavior and facilities design is accounted for, meaning pressure and temperature losses throughout the system are taken into account in each concept differently. These concepts are ranked in terms of economic performance indicators (NPV, IRR, etc.), and each run with a given set of boundary conditions covers what is called an Epoch. This process is iterated for the whole life of field with a set of different boundary conditions, such as commercial aspects ($/bbl, $/MMBtu, market demand) and/or technological maturity aspects (TRL, novel technological concepts), generating what is called an Era. The whole data set is then evaluated in an interactive platform thru the Humans-In-the-Loop (HIL) process.
Model Based Systems Engineering (MBSE) is being employed successfully in other engineering fields outside the O&G context such as the aerospace and automotive industries. While digital tools have been identified as a potential key contributor to the future of O&G performance enhancement and further cost reductions, that is yet to be shown. This work intends to provide backing for that argument in one of the potential applications during early concept exploration phases by showing that quick high value assessments following an MBSE approach may be carried out, once significant effort has been put into proper development, verification and validation (V&V) of such digital tools.
While integrated models for asset development have long been a subject of interest for O&G operators, the application of Systems Engineering concepts to it has not yet been thoroughly explored. Systems Engineering provides a rigorous and proven method of dealing with complex systems that is highly applicable to offshore field developments. MBSE is the current State of the Art for capital intensive projects such as space exploration spacecrafts and rovers. Learning from these successful use cases and applying these methodologies in the development of digital technologies may provide a new set of tools in the belt of O&G operators Facilities Engineers and alike. The study case presented shows MBSE’s capability of capturing intrinsic non-linearities and specificities of each O&G field/location while ensuring project wide functional requirements are successfully met.
Weight control is critical in platforms of offshore oil fields and wind farms. Each engineering discipline is responsible to design their respective system with weight optimization as an important goal. This paper explores the various avenues that are available in electrical system design, that can contribute to weight reduction in an offshore structure.

The obstruction inside flexible lines with hydrates or paraffins is quite common in offshore production systems. In these cases, in order to perform the clearance of the pipes, many different techniques, usually time consuming and expensive, are currently used. This article presents the development of a new self-propelled robot that is under design to become an alternative solution for this problem, which has been a research challenge by decades.
The use of robots with umbilical cables inside long obstructed pipes with several curves and bends is currently an important challenge in the robotic field, especially due to the increased traction forces that may occur. The main challenge is the force in the umbilical cable caused by the friction between the cable and the inner pipe surface. This force can be theoretically outlined by the capstan Euler-Etelwein equation (usually applied to the case of rounding a capstan with a rope). In an early study, a theoretical model for cable traction was developed and experimentally validated. This model was used to calculate a typical friction force in a standard pipeline. Several in-pipe movement strategies were analyzed and a suitable mechanism was defined as the main element for the robot traction mechanism. Therefore, we show in this study that the traction challenge can be surpassed by a properly cable materials selection composed with a suitable traction system design. A mechanism base in an inchworm-like movement was selected due to its high traction capacity and, based in an extensive study, a hybrid (electric-hydraulic) system was developed. The electric power transmission is provided through the umbilical, and electric motors drive pumps which supply hydraulic power to linear pistons that execute the movement of the mechanical elements, moving the entire system. Previous analysis and tests indicate that the designed system will be suitable to perform the necessary missions.
The Netherlands YEPP made a field trip to Total E&P Nederland's Zuidwal gas platform in the Waddenzee (a tidal area in the north of The Netherlands) in February 2004. Participants were given a tour of Total's gas treatment center in Harlingen, including a view of the control room that monitors all of Total's Netherlands operations. It was a pleasant and sunny winter day for most of the boat trip, and our hosts looked after us well. Lijs Groenendaal, SPE section board member and one of our Total hosts, gave a comprehensive talk about Zuidwal's history and development. In 1969, Elf Petroland B.V. was granted an exploration license for the Zuidwal area.
"It took 2 hours for two men to dig a hole 5 ft deep. How deep would it have been if 10 men had dug the hole for 2 hours?" The answer to Edward De Bono's question may seem obvious (25 ft), but some minds may offer answers far from the obvious. How about, "Rain could flood the hole to prevent digging," or "Deeper soil layers may be harder to dig out," or "We may hit bedrock or the water table"? Welcome to the world of lateral or out-of-the-box thinking, which is all about discarding the obvious, leaving traditional modes of thought behind, and throwing away preconceptions.
The Aberdeen young professionals (YPs) group kicked off its 2007–08 technical-events calendar with a presentation on the increasingly important subsea- production sector given by Paul Tooms, global head of Subsea Technology for BP. Tooms was featured in the most recent edition of the The Way Ahead in the Technical Leader series interview. Addressing the Aberdeen YPs, Tooms gave an overview of his BP career of more than 30 years, which has spanned five continents. He described the wide scope of subsea engineering and went on to analyze global subsea investment trends, pointing to a relatively flat projection for capital expenditure on floating production platforms (e.g., spars; tension-leg platforms; and floating production, storage, and offloading systems). However, in comparison, subsea well count is expected to double by 2012, with increasing emphasis on subsea tiebacks to maximize investment on existing production units.
A program titled "The Subsea Story: Adventures from the Deep," was slated for 10 June in Oslo, Norway, as part of the SPE Young Professional (YP) Technical Series. The agenda focused on technical development topics in the subsea oil and gas industry, ranging from subsea processing to recovery workovers from subsea wells. Included on the agenda was a tour of an FMC Technologies facility to provide a close-up view of subsea equipment. The event follows the successful inauguration of the YP European Technical Series with a seminar, "Carbon Capture and Storage--Are We There Yet?", held on 25 March in London. The third session in the technical series, "Economics and Decision-Making in the E&P Industry," is scheduled for 7 October in Amsterdam.
Talos Energy made a big splash in 2015 when it won two of the fourteen blocks offered in Mexico's inaugural Round 1 lease sale. The company and its partners drilled the Zama-1 exploration well in July 2017, the first well drilled offshore by the private sector in Mexico's history, and later announced a massive discovery with over a billion barrels of oil in place. Now the company is moving forward to reach final investment decision and bring the field on line by the early 2020s. Outside of Mexico, Talos has reshaped its portfolio through its recent merger with Stone Energy, becoming public in the process. Following the transaction, the company now operates several US Gulf of Mexico facilities as well as subsea tie-backs.
