Video: vessel launching torpedo anchor for FPSO or oil platform attachment

In a rare act, the video shows how this type of operation in an offshore oil and gas environment is essential to keep maritime units fixed at a point of production

Operated through a type of ship or support vessel, the torpedo anchor is a specific type of anchor used to anchor oil platforms and Floating Production, Storage and Transfer Units (FPSO) on the seabed. These offshore structures are critical to deepwater oil and gas exploration and production and need to be kept stable and secure in their designated positions. The torpedo anchor plays a key role in this anchoring process.

A video shared on social media shows the exact moment a vessel performs the tool's operational maneuver. Check below:

Video: Launching a torpedo anchor

The torpedo anchor has an aerodynamic shape and is constructed of high-strength steel. It is designed to be dropped to the bottom of the sea and penetrate the sea floor due to its shape and speed of fall. By burying itself in the ground, the anchor creates significant resistance that prevents movement of the platform or FPSO.

The main advantages of the torpedo anchor include:

1. Efficient Mooring Capability: The torpedo anchor can quickly penetrate the sea floor and provide a stable and safe mooring for the platform or FPSO.
2. Simplified installation: Compared to other types of anchors, the torpedo anchor has a simpler and faster installation process, since it does not require drilling or excavation equipment, only a ship or support vessel designed for it.
3. Reduced installation costs: The ease and speed of installation of torpedo anchors can significantly reduce the costs associated with anchoring offshore platforms and FPSOs.
4. Application in different types of soil: The torpedo anchor can be used in different types of marine soil, such as clay, sand and gravel, increasing its versatility.

In summary, the torpedo anchor serves to efficiently and safely anchor oil platforms and FPSO units to the seabed, ensuring the stability and safety of these offshore structures during oil and gas exploration and production operations.

Tips for Laying a 120 Ton Torpedo Anchor

• Make sure the launch site is clear of obstacles and has enough space to accommodate the anchor.
• Position the anchor at the launch site and attach it to the launch system. The launching system must be designed to handle the weight of the anchor and provide secure support during launching.
• Verify that all systems are working properly and that there are no malfunctions or issues that could cause boot failure.
• Begin the boot process by triggering the boot system. This may involve hydraulic or pneumatic systems, depending on the launch system design.
• Apply force to the anchor in the direction of release. This can be done using a winch or other mechanical device.
• Monitor its trajectory and make necessary adjustments to the launch system when the anchor starts to move.
• Continue applying force to the anchor until it reaches the desired location.
• H. Release it from the launching system and secure it in place using appropriate mooring lines, once the anchor has been successfully dropped,
• Conduct a post launch inspection to ensure that all systems are still working properly and that there was no damage to the anchor during the launch process.
• Record launch details including launch date and time, anchor weight, launch system used and any other relevant information.

Laying a 120 ton torpedo anchor is a complex and potentially dangerous operation that requires careful planning, attention to detail and proper training. It is important to follow all safety protocols and procedures to minimize the risk of injury or damage during the launching process.
