Survey Vessel
S/V Anne
Your purpose-built survey solution
The S/V Anne is a purpose-built 48-foot survey vessel, commissioned by the Army Corps of Engineers in 2000, and completely refurbished in 2026 for commercial Survey applications. Ideal for the scopes of work and marine applications below.
- Nearshore Multibeam scopes like Pipeline Pull in support, DMA installation, Touch Down Monitoring, Mattress installation as-built, Pipeline pre-lay surveys, Visual inspections and GVI Surveys on As-Set pipeline crossings and Pipeline As-Built Surveys.
- Offshore and Inland Waterway Hydrographical & Geophysical surveys as well as Sediment Management support for ports and rivers, state waterways and channels.
- Existing Asset Monitoring & Inspection, merging ROV Photogrammetry, Multibeam and vessel mounted Drone Lidar in a 3D point cloud with sub-cm accuracies. Offshore satellite platforms and subsea assets, harbors, docks, dams, and bridges.
Vessel is operated & staffed by SEASTX.COM

Vessel attributes and notes
The Anne is fitted with a built-in moonpool that can be used for longer-term projects, while a HighTower universal sonar mount pole is better for shorter-term projects. Equipped with an ROV pad and a 600 lb davit with remote controlled/wired winch as permanent features of the vessel.
The Stolkraft hull consists of a trimaran shape forward that transforms into a catamaran aft. As the vessel moves forward, it forces air beneath the scoops formed by the tri-hulled forebody. The air acts as a cushion that decreases frictional resistance, provides additional lift at higher speeds, and decreases fuel consumption.
S/V Anne’s design provides the capability to operate in higher, rougher sea conditions than is possible from most current smaller survey vessels. It can get to your work area faster than most vessels.
