OFFSHORE EFFICIENCY
AT NPCC ENGINEERING LIMITED a The leading offshore company NPCC Engineering Limited (NEL) is a joint venture of NPCC, Abu Dhabi and Arcadia Shipping, Mumbai, carrying out design and engineering activities for oil and gas upstream industry. NEL’s Quality Management System (ISO 9001:2008) is certified by BUREAU VERITAS and it has carried out several design and engineering projects of new well head platforms, subsea pipelines and topsides modifications on well head/process platform.
N 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 and gas upstream projects such as PDS, PDMS, STAAD, Sacs and Caesar. T 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 and anticipating upcoming challenges NEL decided to switch from traditional 2D based platform to 3D BIM based process & technology. Their obvious choice was Tekla and they decided to implement the software in this fast track green field well head platform project.
WO-16 CLUSTER & SB-14 WELLHEAD PLATFORMS PROJECT s 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, and 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 and 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.
INTEROPERABILITY CONTRIBUTED TOWARDS SUCCESS: The design and 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 and 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. T
COMPLEXITY HANDLED WITH EASE: NEL structural design team worked based on the requirements of client and came up with relevant technical and design issues to be developed and incorporated in the Tekla model. Tekla technical support team and NEL design team worked together during development and 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 a few small requirements of offshore industry incorporation. This can further fine tune Tekla offerings to all offshore players. T

Generating detailed structural material take off list very quickly and accurately during design phase of job. Monitoring weight of the structure and the position of the deck structures center of gravity during the design phase. Direct output of 2D drawings to present to the end user or client and the relevant authorities for approval or certification purposes thus reducing human errors and checking time drastically. The software allows user friendly interface with Piping or E&I models in PDS for reviews and complete clash free structural model. Import of main steel frame directly from analysis software SACS. Using Tekla 3D structural model for regular design review kept it fully coordinated from any conflicts with the equipment, piping, cable trays and access routes.
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 and detailers and fabricators of all materials. Tekla software is made for creating, combining and distributing highly detailed, constructable 3D models. Information-rich models lead the way for production control and 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 Tekla Corporation drives the evolution of digital information models and provides competitive advantage to the construction industry. Tekla software is used worldwide to model all types of structures.
