The key to competitive utilization lies in being able to 3D capture the vessel "in operation" quickly, accurately and inexpensively. The early availability of detailed and accurate 3D studies from laser scan data allows shipyards to get ahead in planning the project, designing the refurbishment, and acquiring materials ready to start work as soon as the ship arrives at the repair dock. The use of scanning helps to shorten downtime.
The typical approach when performing ship checks is to bring designers and/or engineers on board where, using tape measures, they record measurements of the existing systems and spaces. These measurements are then used in developing scope and construction documents. However, the uncertainty of the measurements requires allowances to be included to account for discrepancies between the measurements and reality. These allowances can be expensive and/or prevent the installation of new equipment in a certain location because space was considered too small, when in fact there was adequate clearance. Or, conversely, maybe not enough at the time of installation.
A better approach involves scanning ship spaces with a 3D laser scanner to create a very detailed and accurate 3D point cloud model. Today’s high-speed laser scanners are quite suitable for this purpose as they can take tens of millions of measurements in just a few minutes. Scans are taken from various positions in order to provide sufficient coverage around equipment. The scans are then registered together to bring them all into the same coordinate system. Scans of the ship's hull and keel can also be taken, in which hull curves and surface models can be created for fuel or stability analysis if needed.
3D scanning allows the user to get a very accurate “as build” of the scanned area. This information can be used for different purposes, such as:
Ballast Water Treatment System installation
Scrubber System installation
Ventilation upgrade (duct modifications)
In-service pipe spool replacements
Air Ducts
Hull geometry / Production of Lines Plan
Visualization of damage to the ship structure
Any alteration done to a ship structure or systems
Scanphase offers a 3D laser scanning service to assist owners and yards to be ahead of the market, planning the project, designing the refit and procuring materials ready to begin work as soon as the vessel reaches the repair dock.
Once the point cloud has been designed in a building model, manipulations can be performed on it such as:
Incorporate ballast water systems (BWTS)
Incorporate the installation of the exhaust filter (EGCS)
Make any kind of change in the environment.
Damage repair
Others
Scanphase collaborates with naval companies and field specialists and offers high quality services for shipping companies in all European ports (Portugal, France, Italy, Spain, Malta, Netherlands, Germany, Belgium, Turkey, ...), Spanish ports (Valencia, Algeciras, Barcelona, Las Palmas, Bilbao, Santander, Tarragona, El Ferrol, Cartagena, Avilés ...) and North Africa.
