19 GT FRP High-Speed Patrol Boat

Custom workboat for marine surveys, dive support and debris recovery

High-Stability Offshore Workboat with Custom Equipment Integration

National Park No. 3 is a 19 GT FRP marine patrol workboat designed and built in Taiwan by Shing Sheng Fa Boatbuilding for operations around Dongsha Atoll and the Southern Penghu Islands. Its vacuum-infused hull and main deck, bulbous bow, three 300 hp Yamaha outboards and joystick controls support patrol and survey work. A bow-mounted net hauler and an aft deck fitted for dive teams and instrument handling allow one vessel to support marine monitoring, diving and debris recovery.


Case Background & Client Requirements

Taiwan’s Marine National Park Headquarters needed a vessel to patrol marine protected areas, monitor ecosystems and survey aquatic life around Dongsha Atoll and the Southern Penghu Islands. The workboat had to support the recovery of illegal fishing gear and marine debris during patrols. Survey missions also required space for dive teams, cylinders and research equipment, along with the ability to deploy and recover instruments at sea. These requirements shaped the deck layout, equipment selection and low-speed handling system.

Survey Vessel Type and Configuration Selection

The vessel uses a 19 GT FRP displacement hull with a bulbous bow designed for head-sea performance and course keeping. The hull shell and main deck were manufactured by vacuum infusion to control resin wet-out and laminate quality. The bow accommodates gear recovery equipment, while the larger aft deck provides space for dive preparation and survey equipment handling.

Engineering Enhancements & Custom Integration

A bow-mounted net hauler assists with recovering nets, longlines and traps. The aft deck was planned around the space requirements of 12 diving personnel, 24 cylinders and research equipment. A davit supports instrument deployment and recovery. Three 300 hp Yamaha outboards provide 900 hp of total rated power. Yamaha HELM MASTER EX Level 4, a CL5 display and joystick control assist with low-speed maneuvering, docking and position control.

Operational Results & Performance Benefits

Sea trials demonstrated the vessel’s straight-line tracking and performance in head seas. The program also included high-speed operation at full load and turning trials at full helm to port and starboard. The deck layout places fishing gear recovery at the bow and dive preparation and instrument handling aft. This gives the operator dedicated work areas and allows the same vessel to serve routine patrol and equipment-intensive survey missions.

Classification Compliance & Reliability

Shing Sheng Fa Boatbuilding has welding procedure specifications (WPS) approved by CR Classification Society and DNV. For a custom workboat, the engineering team can establish the plan approval, equipment documentation and testing requirements based on the flag state, intended service, operating area and applicable classification rules. The requirements, inspection scope and certificates for National Park No. 3 are documented in its vessel delivery records.

Maintenance Cycle & Total Cost of Ownership (TCO)

The FRP hull offers corrosion resistance. Owners can schedule inspections of hull surfaces, deck fittings, outboards, the net hauler and the davit according to operating hours and manufacturers’ maintenance schedules. Shing Sheng Fa Boatbuilding provides a one-year warranty, operator training and after-sales support under the contract. When evaluating a similar vessel, owners can compare expected patrol and survey activity, equipment service intervals and vessel downtime as part of the total cost of ownership.
