Custom Vessels

Geodynamics owns and operates survey vessels to support multi-sensor HRG surveys within coastal, nearshore, and deep offshore waters. Capable of 24-hour survey schedules, we maximize data acquisition while minimizing vessel and crew expense.
COASTAL OCEAN RESEARCH VESSELS

Our specialty is multi-sensor surveys in the challenging shallow ocean where offshore ships perform poorly. With 12h or 24h capability, these vessels are shallow draft (3’ to 6’) and can simultaneously acquire multibeam, sidescan, chirp or parametric sub-bottom, single or multi-channel seismic, and gradiometer with layback or USBL positioning.

Shackleford 

Description

The R/V Shackleford has been designed specifically for site development and cable surveys for offshore wind and telecommunications. Constructed and operated according to USCG passenger standards, it supports numerous scientific & vessel crew safely for extended 12h or limited 24h operations. The semi-displacement catamaran hull dampens wave action for improved survey conditions and the hydrofoil design offers quick transits to and from the survey site.
With ample space for vessel operation, data collection, and observation, the R/V Shackleford offers 5 dedicated computer stations, 2 bunk rooms, 2 heads, and a full galley. Sensors can be deployed from the central retractable moonpool, a side-mounted USM pole, or from the large stern A-frame with twin hydraulic winches. Standard dedicated equipment includes a Kongsberg 2040, Edgetech 4205HD, Innomar Medium-100, and Geometrics G-882; alternative or additional equipment is easily integrated. A high capacity SSD server with 10GB network connections and rack-mounted workstations is linked to shoreside offices through bonded cellular bandwidth, with failover satellite service if needed. Crew safety is ensured through redundant modern vessel safety systems, including a FLIR thermal imaging camera, video monitoring feeds, and fire suppression technology.

Substantial

Description

R/V Substantial is the foremost midsize survey vessel available, bridging the gap between survey launches and extended-duration offshore vessels. The Substantial can support up to 6 people conducting 24h operations or 12 people conducting 12h operations. Integrated survey equipment includes a hull-mounted dual-head Kongsberg EM2040 MKII with an Applanix POS-MV, AML Moving Vessel Profil-er, A-frame with Hawboldt hydraulic science winch, and calibrated USM pole mount. Data acquisition stations are connected to a high-capacity SSD server with 10GB network connections with ship-to-shore data transfer through Pepwave Transit Duo with a failover satellite connection.
The vessel has been outfitted to provide best-in-class stability, maneuverability, and safety during survey operations. A Seakeeper 20HD minimizes vessel motion to enhance data quality and safety while working over the side across variable sea states. 20kw of electrical power and an independent hydraulic power unit provide reliability and flexibility for operating broad arrays of survey equipment, and Sleipner hydraulic bow and stern thrusters improve agility. Crew safety is ensured through several state-of-the-art vessel safety systems, including a FLIR thermal imaging camera and a Fireboy fire suppression system.
