3D Laser scanning & survey

Capture the as built structure and piping and equipment arrangement of the vessel

Identify the available space of the vessel to fit the BWTS or scrubber into the vessel

Identify the location of ballast pumps and other components in the vessel.

Locate the obstructions and maintenance space while modeling the BWTS or Scrubber.

Obtain a permanent record for current and future use.

Other ancillary considerations.

What is 3D Laser scanning?

3D Laser scanning is the process of capturing digital data of the shape of an object with equipment that uses a laser to measure the distance between the scanner and the object. In other words, 3D laser scanning is a way to capture a structure or an object’s exact size and shape in a 3-dimensional representation.

3D Laser scanner can capture data of very small objects up to full-sized objects. 3D laser scanners measure fine details and capture free-form shapes to quickly generate highly accurate point clouds. This point cloud is measured from the reflection of the laser from the surfaces of scene objects.

3D Laser scanning is capable of capturing a large amount of data in a short time generating a very large set of points distributed on the scanned object. Rendering the point cloud data enhances the visualization in three dimensions, which allows us to rotate, zoom, walk, etc.

When the laser captures the data points in the targeted area, these captured data points are registered and combined to a Point Cloud data. This Point cloud data provide designers with up to date and detailed information such as pipe size, length, structural cross-section information from the data, computer-aided inspection, or simply documenting for future use.
It allows us for remote surveying where an individual does not need to directly access or work over the site and it provides the as-built data which can be used later or in the future.
3D Laser scanning is widely used in various fields like the Marine industry, Oil and Gas refineries, Industrial design and manufacturing, Reverse engineering, Shipbuilding, Power plants.

Oshiana delivers highly accurate 3D scan data to view the as-built condition of the vessel by using the Faro scene 3D laser scanner, one of the best scanner available in the market. Using the point cloud data Captured, Oshiana design the CAD models of Ballast water treatment system(BWTS) and Scrubber exhaust gas treatment system

BWTS 3D Laser scanning

In earlier times, a design engineer on board uses tapes to measure and records the measurements of the existing systems, spaces available. These recorded measurements are then used in developing engineering documents.

As the earlier method requires a lot of time and errors may occur in measurements, an alternate solution for this is 3D laser scanning as it requires less manpower which takes multiple scans in an hour. A 3D Laser Scanning plays an important role which helps to take decisions to Design Engineers for the installation of BWTS.

Scanning can be done when the vessel is in operation/or at anchorage/or during the port call. Scanning provides precise measurements and high detail of existing piping and structure. All required areas like ballast piping, Engine room & Pump room are scanned with a 3D laser scanner to install BWTS. Scans are taken from various locations to cover the equipment. These scan data can be compared with the design to verify that all components are installed in the correct locations. If any errors are noted, the design will be revised. These scan data can be used for various purposes like BWTS & Scrubber installation, Clash detection, damages to the ship structure, and Air Ducts.

The new BWTS with its piping system can be seamlessly planned and integrated with the scan data. These scan data are used to find out the clashes with the vessel’s existing system and the modification that is needed for the installation of BWTS. To decide how and where to install a BWTS on the vessel, a feasibility study or pre-survey has been conducted by the Oshiana.

Information acquired during Survey & and 3D scanning, Oshiana will start to prepare conceptual model- which will reviewed & discussed time by time.
Once Oshiana receive the green signal from the client, our team enrolled to detail design to produce the fabrication drawing.
