⚓ 9 TYPES OF OFFSHORE VESSELS & UNITS — KNOW THEIR MAIN ROLES! 🚢
Ever wondered how offshore oil, gas, and wind-energy operations are supported far out at sea? 🌊 Different vessels and offshore units are designed to perform specialised tasks, from transporting essential supplies to supporting subsea construction and offshore drilling.
🔍 Explore these 9 important offshore vessel and unit categories:
1️⃣ AHTS — Anchor Handling Tug Supply Vessel: Supports anchor handling, towing, and offshore operations.
2️⃣ PSV — Platform Supply Vessel: Transports supplies, equipment, and materials to offshore installations.
3️⃣ DSV — Diving Support Vessel: Supports commercial diving and subsea inspection, maintenance, and repair.
4️⃣ MPSV — Multi-Purpose Support Vessel: Performs a range of offshore support activities, depending on its equipment and configuration.
5️⃣ CSV — Construction Support Vessel: Assists with offshore construction and subsea installation projects.
6️⃣ SOV — Service Operation Vessel: Supports technicians and maintenance teams working at offshore wind farms.
7️⃣ Jack-Up Barge: Uses extendable legs to support a working platform above the water when properly positioned and installed.
8️⃣ Offshore Drilling Rig: Drills offshore wells for exploration, appraisal, or development.
9️⃣ FSO / FPSO: FSO units provide floating storage and offloading, while FPSO units also receive and process production fluids before storage and offloading.
🛠️ Did you know? Not every offshore vessel has the same capabilities. Its equipment, configuration, operating environment, and intended task determine the work it can perform.
📘 Whether you’re studying maritime engineering, working at sea, or exploring offshore energy technology, understanding these vessel types is a valuable part of maritime knowledge.
