Overview
R/V Odin Finder is a DP1 50m long research, geotechnical and survey vessel, owned by Lighthouse since 2001.

The vessel has performed most of our surveys worldwide, proving her reliability and fitness to the survey operations. Being dynamically positioned, fully permanently mobilised with geophysical and geotechnical equipment, Odin Finder represents the best survey platform for a wide range of services.

The survey and the processing rooms are large and fitted with all the necessary facilities for the acquisition and processing of the survey data. The V-SAT KU Band allows broadband connection for data sharing and communication. The vessel can accomodate 16 among technicians and customers in single/double cabins.

Case Studies
Introduction Lighthouse performed a pre-engineering marine survey for 280km long gas pipeline route in the Atlantic Ocean offshore Cameroon in 2014. The purpose of the hydrographic, geophysical and geotechnical site investigation was to determine the suitability of the proposed pipeline routes and to identify any geological and bathymetric conditions ... Morewhich could impair pipeline installation and associated burial operations.

Scope of Work

The scope of work comprised bathymetric, seabed, and sub-seabed data acquisition, processing and interpretation, performed from Lighthouse's DP1 Odin Finder Geotechnical and Survey Vessel, including:

2D ultra high resolution (UHR) seismic survey

Pipeline routes corridor bathymetric and geophysical survey by means of multibeam echosounder (MBES), singlebeam echosounder (SBES), side scan sonar (SSS), sub-bottom profiler (SBP), and magnetometer

Pipeline routes geotechnical characterisation by means of shallow vibrocorer sampling and subsequent geotechnical laboratory testing

Pipeline routes environmental survey to characterise biologic chemical and physical properties of the seabed and seawater.

Data processing, interpretation, final charting, and reporting

Initial 2D UHR Seismic Geophysical Survey

The 2D UHR seismic survey was performed to detect possible hazard in the shallow stratigraphy for the pipelines routes. The main challenge was to provide the Client and engineering consultant with the necessary engineering data within the expected deadlines in order to proceed with the following phases of the survey. All the acquired geophysical data passed through a rigid Quality Control (QC) procedure, and was processed and finally interpreted onboard the survey vessel. A preliminary interpretation was provided before the start of the geophysical survey (24 hours after the end of the last acquired line), and the final interpretation was provided to the Client at the end of the geophysical survey.

Pipeline Routes Corridor Bathymetric and Geophysical Survey

Once the optimal pipeline routes were determined by the Client, the whole corridor was investigated in order to detect any possible hazard for the future pipeline installation and construction. The main challenge was to provide the Client with information and warning of any potential geohazards in advance of any critical milestones which may have impacted route optimisation or design. The results of the bathymetric and subsequent geophysical survey facilitated the scope for the geotechnical and environmental surveys.

Geotechnical and Environmental Sampling Operations
Following the successful completion of the hydrographic and geophysical survey, Lighthouse carried out the geotechnical and environmental sampling phase of the campaign. This is included shallow sub-seabed sampling using a vibrocorer to provide adequate and representative soil samples for further laboratory testing and analysis, such as soil identification and classification, bulk and dry density, particle size distribution (PSD), and photography for input into the Client's engineering design.

Introduction Lighthouse carried out a pipeline reconnaissance survey for a 112km long gas pipeline route in the Eastern Mediterranean Sea in 2015-2016. The purpose of the hydrographic, geophysical and geotechnical site investigation was to establish the engineering feasibility of two proposed pipeline routes along a pre-defined 2,220km² wide corridor. ...

Scope of Work

The scope of work comprised bathymetric, seabed, and sub-seabed data acquisition, processing and interpretation, performed from Lighthouse's DP1 Odin Finder Geotechnical and Survey Vessel, including:

Pre-survey route centreline survey

Post-survey route centreline and two wing lines 500m offset each side of centreline survey

Pre-defined corridor survey

Geotechnical characterisation by means of box core sampling, piston coring, and geotechnical laboratory testing and analysis

Data processing, interpretation, and integrated hydrographic/geophysical/geotechnical reporting

Hydrographic & Geophysical Survey

The pre-survey route centreline was investigated by means of multibeam echosounder (MBES) and sub-bottom profiler (SBP) to detect and assess any geohazards or potential issues for the proposed pipeline installation. The survey data was processed onboard simultaneously and provided to the Client in order to facilitate survey optimisation and acquisition of additional data if required. Once the post-survey route was defined, the survey was extended to cover a wider corridor. The geophysical survey was subsequently continued to cover the pre-defined corridor area.

Geotechnical Sampling Operations
Following the successful completion of the hydrographic and geophysical survey, Lighthouse carried out the geotechnical sampling phase of the campaign. This is included shallow sub-seabed sampling using box corers and piston corers to provide adequate and representative soil samples for further laboratory testing and analysis, such as soil identification and classification, bulk and dry density, particle size distribution (PSD), and photography for input into the Client's engineering design.
