SEABED SURVEYING
FEATURE SPONSOR
SUPERIOR SUBSEA SURVEY
FROM CONCEPT TO COMPLETION AND BEYOND INDUSTRY EXPERIENCE
Subsea surveys provide developers and offshore contractors with vital information to help build and maintain cost efficient offshore windfarms and subsea power networks.
Surveys are performed throughout a project life cycle and help develop field layout, subsea cable routes, identify UXO and other seabed obstacles, support cable lay activities and enable subsea inspection of infrastructure to ensure integrity and operational longevity.
PROJECT SOLUTION PROVIDER DeepOcean is an innovative project solution provider and supports subsea renewable and interconnector projects from concept, engineering, survey, installation and protection through to subsea inspection and maintenance.
One of the company’s many strengths is its impressive track record in subsea survey, having surveyed and inspected more than 70,000km of subsea product. In addition, its subsidiary ADUS DeepOcean has recently undertaking the post-construction bathymetric survey of all infield assets for the Greater Gabbard windfarm, including assessment of cable condition and scour assessment.
DeepOcean has installed over 1000km of subsea power cable and performed associated lay and burial verification surveys. The company has recently secured contract awards to survey, install and protect subsea array, export and interconnector cables on Bligh Bank, Race Bank, Walney Extension and NEMO Link.
TECHNOLOGY INVESTMENT To ensure clients receive the optimum survey the company continually review operational performance, improve methodology and invest in the latest technology, such as high density video, subsea laser technology and 3D visualisation software, to improve the gathering of data processing and visualisation.
The formula to a cost effective survey is speed and quality. The company’s extensive experience in performing acoustic and visual surveys with ROV’s, ROTV’s and AUV’s highlighted that AUV’s offer speed but sacrifice options to stop and re-run sections and areas to check findings immediately, whilst traditional ROV’s provide high quality data acquisition, but up until now are somewhat slower.
SOLUTION
To tackle this shortcoming, DeepOcean undertook several years of conceptual engineering and development to optimise an ROV platform with the aim of doubling the common survey speed, whilst retaining capacity to carry a suite of multibeam echo sounders, side scan sonars, sub bottom profilers, UHD camera’s, laser profilers, a conductivity probe stabber arm as well as a manipulator for light intervention.
