We have experience, in serving clients across industries including oil and gas marine, renewable energy, defense and more. Our expertise lies in designing types of structures such as permanent installations, floating units and mobile platforms like jackets, FSO/FPSO/FSRUs, Semisubs, Liftboats and MODUs. Our dedicated team offers a range of services including investigations concept design development (FEED) and detailed engineering, for new projects. We strive to deliver solutions to meet the project requirements. Our team of professionals utilizes the equipment and technological advancements to perform design analysis effectively. Various industries such, as construction, plumbing, mechanics, electrical work and instrumentation involve the design process. When designing something it is important to consider local standards, for both current and future operating conditions. The specific components that require these studies include topsides, accommodation units, crane supports, process modules, helidecks, equipment foundations, cantilever drilling platforms, jackup legs, spudcans and more.
During their existence, offshore units may need to undergo significant or minor adaptations for certain projects, to improve their capabilities, or to extend their life. One of our main specialties and areas of expertise is offering engineering services for upgrades and conversions for different kinds of offshore units for clients all around the world. Numerous complementary services offered by the group, including as inspections, surveys, equipment procurement, project management help at yards, commissioning assistance, etc., give our clients an advantage in completing projects more quickly, safely, and affordably.
Asset integrity and asset life extension services are offered in a variety of ways by Sealand. Engineering assessments for asset life extension typically take into account a number of variables, such as wear and tear, degradation, fatigue damage, changes in the environment, operational aspects, corrosion protection, changes in the design basis, potential strengthening options, development of a periodic inspection philosophy, etc. As part of these asset life extension studies, a number of analyses are conducted, such as global strength analysis, fatigue analysis, pushover analysis, etc. Asset life extension studies frequently make use of other services provided by Aries, such as 3D scanning and intelligent engineering solutions.
In all engineering disciplines, finite element analysis is an effective technique for validation and optimization. To the client's satisfaction, FE experience including global models as well as microengineering aspects of connecting details has been completed. The need for FE analysis occurs in a variety of engineering issues involving offshore structures, such as new designs, conversions, upgrades, life extensions, decommissioning, etc. In these projects, several global or local finite element models are created to precisely replicate the linear and nonlinear structural reactions under challenging loading situations.
The most popular technique for the optimization of lasting, floating, and mobile offshore platforms is global strength analysis utilizing FE methods. This requires many engineering man-hours and years of expertise. For numerous clients in the Middle East and other regions of worldwide, a global strength analysis of jacket platforms, floating units, and self-elevating platforms has been completed to the satisfaction of the customer and class. give round-the-clock assistance for the market's changing needs. According to industry standards, we also perform a 2/4 keep inquiry for ship-shaped floating units, which optimizes the overall analysis by focusing on two or three cargo holds and limiting the size of the model.
The assessments completed for installation cover a number of installation stages, such as payout, deployment of the splash zone, pull-in of the J-Tube, installations on the the bottom, etc. For various stages of pipe/cable lay, including the opening, normal lay, temporary put down, recovery analysis, etc., static and dynamic analysis is performed for a wide range of scenarios. Our core team is well-versed in all commercially available tools and coding to offer you high-end support for the essential elements. Our offerings consist of,
After conducting a concept/feasibility analysis on all significant EPCI projects, the FEED study is the first stage of fundamental engineering. We have always stood out in the industry thanks to our FEED studies that are affordable. Our FEED plans are concentrated on the project's technical specifications and account for the whole asset lifecycle. For the many disciplines involved, such as naval architecture, fundamental, pipe work, mechanical, electrical, instrumentation, etc., appropriate quality and depth of engineering documentation is produced. Our clients may make important decisions and prevent major modifications during the execution phase with the aid of the FEED, which also provides them with an approximate investment cost.
Our team is familiar with many kinds of mooring analysis projects for temporary, long-term, and permanent mooring of units in offshore environments. Spread mooring, single point mooring, CALM buoy mooring, or turret mooring techniques are all used by offshore units for different purposes. For floating units, berthing analyses are performed to determine the operating constraints and ensure that the units are safely moored to jetties or other offshore infrastructure. Our internal team of naval architects and hydrodynamics engineers are proficient in the most recent industry tools and help clients with unique engineering solutions for full mooring and berthing study.
When a unit is installed and ready to perform its expected activities and operations, inplace assessments are meant to evaluate how well it will perform under all possible loading circumstances. Offshore units may encounter a variety of complex loadings from a dynamic offshore environment under operating and survival conditions, such as wind, wave, currents, seismic activity, service loads, ship impact, accidental loads, etc. All applicable conditions are taken into account in in-place analyses.
The goal of preservice assessments is to evaluate the suitability of units for all foreseeable loading scenarios before the unit is installed and ready for its anticipated function and activities. Depending on the type of unit and its applicability, we examine a number of pre-service conditions, such as lifting, land transportation, loading, ballasting, sea fastening, sea transport, launching, upending, float-over, mating, on-bottom stability, installation, pile driveability, etc.
Throughout the course of that it exists, an offshore facility is subjected to environmental loading, which results in cyclic stress changes in its structural components and the potential for fatigue cracking in these members. When creating new designs, fatigue analysis is done to determine the design life as well as in life extension projects to determine the remaining and expended life. Various types of structures vulnerable to cyclic loadings under wave actions or operating cyclic loads, such as offshore jackets, floating unit hulls, crane foundations, vibrating equipment foundations, mooring systems, etc., are frequently the subject of fatigue studies.
Offshore disposal facilities often follow the installation procedure in reverse, although they may face very complicated issues due to a number of factors like age, operating constraints, tool availability, environmental constraints, legal considerations, etc. We offer our clients engineering help to effectively and safely carry out offshore decommissioning activities while reducing hazards. Decommissioning initiatives typically require a number of pre-service analysis requirements as well.
