WO-16 CLUSTER & SB-14 WELLHEAD PLATFORMS PROJECTs This project is a new well head platform which is supported on four legged fixed jacket structure with two legs having single batter and other two legs have double batter. Jacket is made of tubular sections, welded together & it is anchored in seabed with main/skirt piles. Jackets have spider deck at top level and have diagonal bracing in all faces connecting horizontal framing levels. It also includes boat landing, buoyancy tank, anodes, riser, skirt pile guide, lifting/upending trunnion etc. Maximum jacket weight is 2100MT. The platform top side consists of sub-cellar deck, cellar deck, main deck and aluminium helideck. Top side also includes building module, vent boom, crane pedestal, solar panel supporting platform, well head access platform, walkways, stairways, ladders and railings. Maximum topside weight is 1900MT.

a NPCC Engineering Limited (NEL) a leading offshore company is a joint venture company of NPCC, Abu Dhabi and Arcadia Shipping, Mumbai carrying out design & engineering activities for oil & gas upstream industry. NEL’s Quality Management System (ISO 9001:2008) is certified by BUREAU VERITAS and it has carried out several design & engineering projects of new well head platforms, subsea pipelines & topsides modifications on well head/process platform.

NEL had a task to create well head platforms at WO-16 and SB-14 cluster field located at South East of SH process complex of Mumbai High Field in water depth of 75 to 80m. The project scope consists of 5 new well head platforms and 2 major deck extension on process complexes. NEL was already equipped with high end softwares needed for oil & gas upstream projects such as PDS, PDMS, STAAD, Sacs, Caesar, etc. There was need to have 3D software to handle their all structural needs start from concepts to engineering/detailing/fabrication to erection. After extensive evaluation & anticipating upcoming challenges NEL decided to switch from traditional 2D based platform to 3D BIM based process & technology and their obvious choice was TEKLA and they decided implemented TEKLA in this fast track green field well head platform project.

INTEROPERABILITY CONTRIBUTED TOWARDS SUCCESS:TThe Design/Modeling of the structure was done with the Tekla Software right from the early stage. Modeling began with the main steel & secondary steel structure as soon as the calculations were completed with SACS. The model is completed later with all the tertiary elements such as the connecting plates, equipment supports, access platforms, padeyes, stiffeners, node plates, cut outs & penetrations as the vendor information was made available. The robustness of the software in dealing with the changes was beneficial in the overall smooth execution of the project

TEKLA IMPROVES OFFSHORE EFFICIENCY AT NPCC ENGINEERING LIMITED

COMPLEXITY HANDLED WITH EASE: T NEL structural design team worked based on the requirements of client and came up with relevant technical /design issues to be developed and incorporated in the Tekla Model. Tekla technical support team and NEL design team worked together during development & customized few Tools as per the project requirement. Although the project had time constraint, NEL managed to achieve defined results in relatively short period with the help of versatile TEKLA software and the excellent implementation support provided by the Tekla team. In the process of project execution Tekla local support team got valuable feedback on few small requirement of offshore industry upon incorporation of which will further fine tune Tekla offerings to all offshore players.

NEL RECEIVED THE FOLLOWING BENEFITS:G Generating detailed Structural Material Take off list very quickly & accurately during design phase of job.M Monitoring Weight of the structure & the position of the deck structures C.O.G during the design phase.D Direct Output of 2D drawings to present to the end user / client and the relevant authorities for approval/ certification purposes thus reducing human errors & checking time drastically.T The Software allows user friendly interface with Piping/E&I models in PDS for reviews & complete clash free structural model.I Import of main steel frame directly from analysis software SACS U Using Tekla 3D structural model for regular design review kept it fully coordinated from any conflicts with the equipment, piping, cable trays, access routes, etc

OTHER SAILENT FEATURES OF TEKLA STRUCTURES HELPED ON A FAST-TRACK PROJECT ARE:G Easy to learn and implementT Tekla structures allows simultaneous access by multiple users to the same modelW Web-link facility allows engineers to review the model simultaneously as it is getting developed.T Tekla Structures users can streamline the design/fabrication processes, ultimately ensuring the highest level of quality in project deliverable.F Free tools Tekla BIMsight for every NEL team member involved in projects to communicate collaborate with other.

OUR AMBITION IS TO MULTIPLY YOUR POTENTIAL TO THINK AND ACHIEVE BIG

W With an ambition to multiply its customers’ potential to think and achieve big, Tekla provides a BIM (Building Information Modeling) software environment that can be shared by contractors, structural engineers, steel detailers and fabricators, as well as concrete detailers and manufacturers.

The highly detailed as-built 3D models created, combined and distributed with Tekla software enable the highest level of constructability and production control.

Centralizing building information into the model allows for more collaborative and integrated project management and delivery. This translates into increased productivity and elimination of waste, thus making construction and buildings more sustainable.

T With its software, Tekla Corporation drives the evolution of digital information models and provides more and more competitive advantage to the construction and infrastructure industries. Tekla was established in 1966, and today it has customers in 100 countries, offices in 15 countries, and a global partner network.

Tekla software is used worldwide to model all types of buildings. Visit our website to learn more about Tekla solutions and references for building and construction.
