Event description

Description

The Hydrographic Society in Scotland invites you to an evening meeting on

Imaging techniques and technologies.

At The Carmelite Hotel

With the following presentations:

‘3B or not 3B? That is the question’ by Dr. Grant Thomson of Savante Offshore Services Ltd.

Class 3B subsea laser scanning has enjoyed a renaissance in the production of high-value, asset-integrity reporting products. Photogrammetry, potentially a more flexible technique supported by emergent camera technologies, is approaching a similar measurement capability. Future IRM, construction and dim-con projects will soon need to ask the question. When should we select the laser and when photo-grammetry to solve our measurement problems?

We present some 3d models of assets using a variety of both inspection techniques to illustrate the relative value of each. We also present limited survey results using a novel Class 3B dynamic subsea laser scanner. This was used to measure the separation of buoyancy blocks supporting the catenary of a dynamic production riser without the support of third-party INS, Fibre Gyro or LBL position referencing tools.

‘Spool Metrology by Subsea LiDAR - the Whole Picture, A Project Perspective’ by Lee Blinco of i-Tech Services

A case study detailing the methodology decision process, planning, operational experience and successful delivery of a particularly challenging spool metrology. The spool metrology in question was hampered by vessel schedules, access constraints and a congested worksite. Subsea LiDAR was chosen as the best method to perform the metrology and delivered the required spatial information along with additional data that lead to significant savings to the project.

‘Vision technologies to increase efficiency in positioning and measurement during drilling and construction activities offshore’ by Alastair McKie of Fugro GB (North) Marine Limited.

For accurate positioning or attitude measurements subsea typically acoustic and/or fibre optic gyro equipment is used. Quite often this equipment is relatively costly and involves time-consuming calibration procedures. Fugro has developed QuickVision, an augmented reality survey toolkit which employs cost efficient sensors that can be used operationally within minutes subsea.


Presentations will commence at 19:00.

The bar will be open from 18:30 and a buffet provided prior to the meeting.

This event is open to members and non-members of The Hydrographic Society.

There is a charge of £10 cash for admission (please ask at the door if you require a receipt).

Admission is free for full time Students.

CPD Event: This event qualifies as continued professional development for members of appropriate professional organisations such as RICS & ICES.
