SEAWORKER Autonomous Surface Vehicle (ASV)
The C-Worker 5 is an autonomous surface vessel by L3 Harris that is equipped with a 57hp diesel engine and has a top speed of 8 knots, endurance of up to one week, and a 5.6m x 1.8m footprint. The vessel comes equipped with AIS, radar, multiple shore communication systems (cell, iridium, and VHF), as well as a 360 degree visible and infrared camera system for situational awareness. Also included is a winch and a-frame for profiling sensors from the ship’s stern. There is a payload bay inside the hull to house electronics and data acquisition systems to sample additional vessel-mounted and vessel-profiled sensor packages.
The SEAWORKER (Submesoscale Environment, Autonomous Weather and Oceanic Research embarKER) is the Air-Sea Interaction Laboratory’s specific version which combines the C-WORKER 5 platform with a custom instrument payload package designed to sample the upper ocean and lower atmosphere. The payload is currently under development and the instrument list below will be updated as the integration evolves.
