Introduction

The Vortex STORM 3-inch is characterized by the following advantages:

• No depth limitations

• Quick mobilization

• Easy operation

The STORM 3-inch dredge Is designed for higher capacity hydraulic supplies that enable a dredge Inlet vacuum up to 29.5 in/hg (100 kpa) at 206 bar and 39lpm. The Vortex STORM ROV 3-inch is designed for Subsea excavation and disposal of seabed materials up to 75 millimeters in size. It can be mounted to any Work Class ROV and requires no ship deck space and sea fastening. The Vortex STORM 3-inch is very powerful, has no depth limitations and is quick and easy to mobilize and operate.

Dredge must NOT be run in air. Only in water.

The Vortex STORM 3-inch equipment can be operated and maintained by the ROV crew.

Ease of mobilization is key with supplied ROV installation bracket in the kit. The client needs to see rapid deployment of hire gear. The entire kit is shipped in one single box.

Your safety is your responsibility. Please ask if you are unsure about anything.

Introduction continued Operating Limits

The operating limit for the Vortex STORM 3-inch , will be the responsibility of the Senior ROV person on-site. The limitation being the ability to safely deploy and recover the ROV system with the Vortex STORM 3-inch attached. Care must be taken whilst during launch and recovery operations to prevent damage to all components of the dredge system and the ROV.

Risks - Normal Operations

All personnel involved in deck operations shall be aware of the potential risk described hereafter.

• Crane Handling (possible danger of e.g. heavy falling object)

• Launch and recovery of equipment over the side of the vessel

• Personnel working over open sea (typical personnel working with launch and recovery of equipment from vessel

deck or moon pool)

• Object falling down from height (rocks following the equipment when recovering)

• Working with equipment under pressure (hydraulics or water)

• Hydraulic oil spillage

Safety
