The increasing demand for natural gas is encouraging the development of novel floating units’ designs, capable processing large quantities hydrocarbon. These units called FLNG (Floating Liquefied Natural Gas) are facilities that produce, process and store liquefied (LNG) offshore. Once topside tanks a larger more complex than regular FPSO vessels, design considering these particularities must be used. just few under construction not yet in operation, information on first stages poor. It...
Ship-to-ship (STS) operations have been widely applied worldwide for the last years from military to oil/LNG cargo transfer, in order improve operational efficiency. In years, lack of available berths/terminals Brazil has increased transfers anchored Ship-to-Ship operations, avoiding pier occupation. This operation is already performed and abroad sheltered locations. However, most locations also ecological restrictions, motivating accomplishment this kind non-sheltered regions, i.e. close...
This paper presents the analysis of Ship-to-Ship (STS) operations in both berths Mucuripe Port Oil Terminal (CE, Brazil). Since it is a new operation this (that was not originally designed for), state art engineering tools used to aid and assure safety personnel environment integrity structures equipments. All procedures are based on PIANC Report n° 121-2014 detailed design phase. Initially, hydrodynamic model calculate waves current along all access channel sheltered area, for long period...
The water transportation of cargo is, among several possible modes transportation, the most economically and environmentally efficient. Adding technology to pusher-barge systems increases efficiency this form transport. It is not only limited design manufacturing process, but extends training commanders crews. An efficient way ensure immersion in virtual scenarios that simulate reality. To have realistic response simulator external commands boundary conditions, it necessary understand...
Many situations in the Offshore Industry require equipment to be launched sea floor, becoming important measure or estimate their final position and/or determine complete trajectory. Some examples are installation of anchorage devices, manifolds production line supports. The main problem associated with estimation and trajectory is related fact that, systems such as GPSs magnetometers cannot used subsea conditions. Gyrocompass precise inertial sensors can used, but they expensive equipments...
This article deals with the development of a numerical tool based on an integrated synthesis model to carry out first project cycle floating liquefied natural gas (FLNG) platforms produce, process, store, and export (LNG). The topside configuration, tank geometry capacity, production levels, equipment list, environmental operating conditions, classification society requirements, structure, stability, seakeeping are considered in single model, generating sufficiently large number solutions....
Image based methods, particularly those applying stereoscopic approaches, have difficulty in measuring waves produced laboratory facilities, mainly because, such conditions, the water surface is smooth, translucent and highly specular. The present study introduces a method to estimate regular wave parameters (particularly amplitude) that capable of dealing with characteristics surface. on image intensity its relationship normal. Although concepts behind are well known since 1960 decade, we...
Torpedo pile has become one of the most popular foundation systems in Brazil’s offshore oil exploitation, mostly, due to its low installation cost. Additionally, torpedo piles have shown good fixation capability even when applied mooring configuration such as taut leg with relatively close angles vertical. This is closely dependent depth penetration and final attitude pile. In order determine these parameters, MEMS-based Inertial Measurement Units been used. this kind are known for high...
