Army Engineer and Navy Seabee units employed the Port Improvement via Exigent Repair (PIER) technology, assessed its viability and further matured the training construct. PIER applies modern technologies to assessment and rehabilitation of waterfront assets for use during military vessel off-on/load of equipment, supplies and personnel. The Multifunctional Assessment Reconnaissance Vessel (MARV) is a cutting-edge, unmanned vessel designed for surface and subsurface port inspections, obstacle detection and precision data capture. It makes the ingress and egress phases of multi-domain operations more efficient and faster by exploiting highly detailed hydrographic in near real-time. The data supports selection of approach vectors, harbor and pier repairs, and remediation of obstacles as well as support to shore operations using co-dependent technologies in the PIER program.
