The first objective is to hand over the neutral scan file in ASTM E57 file format and follow by Autodesk Product scan file to TOI and TOI’s customer, Talisman Sinopec who wishes to do the clash check of deploying BOP over Christmas Tree. The videos contained in this 3896-1 series shows the walk through path inside the cloud scan of BOP scan data collected by RE surveyors. For more information, refer to 3896-1 Sedco 712 Colour Panoramic Photographic Records of BOP Wellhead Frame and also 3896–3 Sedco 712 BOP Wellhead Frame Headcam Video. All this data is then processed and issued to Transocean and Talisman Sinopec to be used primarily as a clash check. Any changes to the frame since 2013 that have been made to the structural framing from the time the As Built Drawings were checked out are therefore captured in laser scan and can be used to produce the latest state of the construction as exists today.

46 – BERLIN – ARCHITECTURAL BUILDING ELEVATIONS -3D COLOUR LASER SCAN-

A total of 10 steel balconies are to be installed on a building facade in Berlin. Proposed Installation will take place in two stages. In the first round, scaffolding will be installed and steel consoles will be mounted to the wall to provide fixing points for the balconies. The steel structure will then be assembled on site and fixed to the steel consoles. A 3D colour laser scan was captured to provide data for detailed CAD design. Data was registered and exported to CAD software for drafting straight from point cloud. Based on laser scan data, 2D CAD drawing with precise location of window and door openings was created. Then, designed layout of steel consoles was superimposed with CAD drawing giving final deliverable i.e. coordinates of steel consoles in reference to windows and doors openings. This deliverable enabled precise definition of steel consoles coordinates before scaffolding is installed and allows to define drilling points (for steel consoles installation). This index and give reference to any easily accessible characteristic point e.g. corner of window to work to. This video footage shows a walkthrough in the cloud of this facade.
 

3799- TEEKAY PETROJARL FOINAVEN – REALITY DETAILED DESIGN IN THE CLOUD OF NEW SEWAGE TREATMENT PLANT IN BOTH STRUCTURAL AND PIPING ASPECT

IH3650-4 WELLHEAD RE-ENTRY CONE FOR BOP

A wellhead re-entry guide cone will be integrated in to an existing BOP for well intervention in the upcoming program. Neither of the components come with certified dimensional drawings to which engineering detailed design, analysis and fabrication can commence. This video therefore traces the start of the engineering process through to the end point of the work flow life cycle i.e. from “cradle to grave” to allow for the optimum design process to be realised. Laser scan cloud data for both components as well as Christmas Tree was carried out using 3D colour laser scanning technology. Once the guide cone was modelled In 3D CAD environment, detailed design to suit functional requirements was carried out and followed by Finite Element Assessment to simulate the response of the proposed design when subjected to impact load – stabbing in to the well head mandrel. To keep man-hours and cost to a minimum, only the new part in CAD is modelled and this allows direct porting back in to the cloud without modelling the offshore environment in to expensive 3D CAD normally deployed by other design house. Clash check using data from Offshore Operations Personnel has been used to simulate the path from BOP set back area over to the moon pool location where the head room is reported to be most critical. Video walkthrough charted this path to allow Project Team to do the “dry run” ahead of the operation itself.

 

IH3650-3 MEETING MARPOL 73/78 ZERO DISCHARGE CAMPAIGN – DECK DISCHARGING PENETRATIONS – Catalogue of Penetrations for Manifolding Purpose

Physically accounting for all deck penetrations allowing for preparation and implementation of zero discharging of any liquid discharging overboard using Ship Yard As Built (SYAB) alone, is fraught with problems and uncertainties. Firstly, the As Installed information of deck drains, scuppers and opening rarely find its way back to the previously Approved For Construction Drawings (AFC) and secondly, adding or relocating or blanking off deck drains / penetrations are routinely done to assure deck is kept dry. As such, to meet MARPOL’s requirements, Rig Engineering has accounted for all deck opening using 3D colour laser scanning technology. With the captured cloud scan, spool piece, tie ins, pipe supports and candidate hangers for scaffolding during installation can be pre planned, well ahead of the vessel arriving for the actual installation. In this real life case study, a series of colour laser scan were done from under deck on the pontoon to identify all the openings that are detectable and forms part of the manifolding system to collecting tank on one of the stability columns of the vessel. This can then be discharged at suitable interval as required, to supply vessel and offload to shore side.

 

IH3650-2 REMODELLING OF BALLAST AND SEAWATER SERVICE – DOUBLE ISOLATION VALVES – Feasibility Study and Spatial Arrangement-

Scale drawings in 2 or 3D of mechanical components and piping system rarely formed part of Ship Yard As Built Drawings (SYAB) when the vessel was delivered. Most of the time, only schematic drawings existed just to allow for the shipyard to install Owner Furnished Equipment (OFE) and incorporate in to the Ship Yard provided connecting pipe work. Subsequent maintenance, modification and upgrade is fraught with lack of dimensions and spatial arrangement information to allow for the visualisation of the installation and maintenance space around the components to be replaced. Rig Engineering routinely laser scan the candidate area and conduct reverse engineering and produce a 3D spatial arrangement in the laser scan cloud in a ready state to receive new / proposed components. Using today’s drawing package norms of CAD or 3D component object, the planned system / space can be populated with all the components necessary to make the new system work. A virtual walk around of the planned installation inside the laser scan cloud, can be done quickly to unearth any installation problem well ahead of cutting POs for all the components to make the modifications works first time.

 

IH3650-1 IN THE CLOUD 3D DESIGN TO FABRICATION AND INSTALLATION PACKAGE –Engineering Workflow Assisted by Virtual Installation Walkthrough–

Approved For Construction (AFC) drawings package that are provided at the time the vessel was delivered, rarely contains deviation / site fit detail to show final, certified Ship Yard As Built (SYAB). Recognising this and couple with post-delivery added construction, interaction with piping, electrical components entering and residing in the same space, Rig Engineering routinely do the detailed design in the cloud scan itself. This way, clash check, no “Green Stock” and visualisation of how the proposed design and construction will look, can be finalised and closed out long before the actual physical installation phase begins. In this example, the existing area has been colour laser scan and the new construction, shown in GREEN colour, can be visualised and clash free installation is assured. For original colour laser scan to which this virtual construction was superimposed on to, refer to 3560-2 GALAXY III HELIDECK CONSTRUCTION VERSUS SYAB FOR DESIGN SANITY CHECK– Engineering work flow assisted by 3D Panoramic Cloud scan –

 

3773-14 – PARAGON MSS1 – BALLAST AND SEAWATER SERVICE DOUBLE ISOLATION VALVES – Background Work to Accommodate Modification to Existing System-

Following Headcam video walk through while Rig Engineering surveyor was on board the vessel, refer to 3773-2 Paragon MSS1 Ballast And Seawater Service Double Isolation Valve Survey Headcam Video, a portable 3D laser scanning / surveying device was used to capture the volume of the work place in this specific area. For walkthrough inside cloud scan of this area in existing stage i.e. Pre Modification, please refer to 3773-13 – Paragon MSS1 – Ballast And Seawater Service Double Isolation Valves. Animation of components removal to make way for the new parts deemed necessary for the intended modification thereafter, is then developed under this 3773-14. Once the proposed design is done, the intended installation sequence, clash check etc. can be simulated in this 3D cloud environment. Combination video and future virtual walk through of the new installation (ahead of actual physical works) will aid the on shore project team and their contractors during project meeting, design briefings and ahead of physical work slated to be done in 2016 i.e. from survey to commissioning.

 

3773-13 PARAGON MSS1 – BALLAST AND SEAWATER SERVICE DOUBLE ISOLATION VALVES

This video familiarisation footage has been captured with the use of Rig Engineering survey tool ( A 3D laser scanning portable device) during a site visit on-board the Paragon MSS1 Semi-Submersible drilling unit, July 2015. The purpose of this site visit was to glean information for the various work scopes planned to be executed during the 2016 Out Of Service period (OOS). This video that has been created inside the point cloud shows the current arrangement of the starboard ballast piping immediately downstream of the seachest. It is planned to install a second valve between the seachest and the strainer to provide double isolation. The harnessed information can be used to overlay a 3D model of the new valve, modified pipe spools, re-position strainer & modification to the platform above, all inside the cloud. This will also allow a clash check of the modifications to be performed prior to any onsite works commencing. This video will also aid the on shore project team and their contractors during project meeting and briefings.
