The vessel, which measures 14.2m x 9m, was recently li%ufffded from the dockside wharf into a pontoon, which leads into Plymouth Sound.USV-Pioneer is a dual-use solu%ufffdon for ocean monitoring and data collec%ufffdon, meaning she has been developed for both commercial and security use cases. Her moon pool enables the deployment of a modular 20%ufffd ISO TEU payload of up to 6.5t, meaning she can deploy freight, but more specifically launch and recover subsurface systems, such as ROVs; or aerial systems, such as UAVs.Carl Coysh, depot manager at RSS Plymouth, said: %u201cThe vessel was originally going to be li%ufffded using some custom beams loaded onto the deck of the vessel; however, we came up with an alterna%ufffdve system to relieve any pressure on the vessel itself, performing a near ver%ufffdcal li%ufffd, which was not only safer, but more economically viable for the project.%u201dAt the top of the rig were two 15t capacity, 12m-long roundslings, which connected to a 6.5m-long MOD34 spreader beam. Four 10t capacity, 6m-long roundslings were rigged below, where a pair of MOD12 beams were used at spans of 3.25m. To complete the system, four 15t capacity, 3m-long roundRope and Sling Specialists Ltd.
