SplashDrone 4 takes maritime activities to new heights

Since 2015, SwellPro has been providing waterproof drones to coast guards and mariners for various maritime missions in many countries. The latest SplashDrone 4 is more powerful and versatile with more options of functional payloads than earlier models. It allows operators to collect valuable data above the ocean whilst reduce the time, cost and danger of the operation. Being waterproof means that the drone can always survive in a marine environment.

Maritime Security Surveillance

Coastguard uses SplashDrone 4 to identify and intercept unauthorized entry, smuggling, piracy, trafficking and other illegal activities in a restricted area of the ocean. The drone can carry a megaphone, allowing operators to deter suspicious ships with voice. Security surveillance by SplashDrone 4 increases productivity and save the cost on boats.

Ship Inspection

SplashDrone 4, fitted with a high-resolution camera, can fly around a ship to identify defects without having a person climbing up scaffolding. The aerial inspection allow seaman to diagnose the defects and repair the ship while at sea with a substantial reduction in time and cost than any traditional methods.

At-sea Search & Rescue

SplashDronne 4 can scan large areas of ocean and pinpoint people in distress, sinking vessels and planes lost at sea. When fitted with a payload release mechanism, SplashDrone 4 can drop a floatation device to people who are struggling in the surf. The drone save coastguards precious time, and more importantly enable them to save more lives.

Marine Biology

Marine conservationists have long been using SwellPro waterproof drones to remotely track and monitor the health of marine mammals such as whales and seals. A drone is less intrusive, more cost-effective and easier to maneuver than a boat. When fitted with a container, SplashDrone 4 can even collect whale snot samples for further study. 

Ocean Pollution Monitoring

SplashDrone 4 can help ocean activists locate plastic debris or find the source of oil emission on the ocean. By mapping out the entire polluted areas from the drone, they can work out a effective plan to remove the garbage and clean the water. 

Maritime Drone Delivery

Being capable of lifting up to 2 kg, SplashDrone 4 can rapidly deliver small spare parts or documents from shore to ships or ship to ship. The drone can automatically fly to a predetermined GPS coordinates on the APP’s map which could be the place of delivery.

SplashDrone 4 Tests at sea by SNSM La Rochelle

SNSM La Rochelle is a French nonprofit organization whose mission is to rescue human live in danger at sea or on the coasts. In this video, they demonstrated how easy it is to use SplashDrone 4 to deliver a self-inflating buoy and a rope for boat towing.

Floatable & Flippable

SplashDrone 4 can float on the water without adding external floating foams. When the drone turns upside down on the water for any reasons, a Power-Flip feature turns it back to the normal state to take the control back.

Level 7 Wind Resistance

A strong propulsion system and an robust GPS position holding system empowers SplashDrone 4 to fly safely in strong wind up to 33 mph / 53 kph.

IP67 Waterproof

The fuselage of SplashDrone 4 is made from ABS composite material exclusively engineered for the marine environment. The aircraft is entirely water-sealed and air-pressure tested to guarantee 100% waterproof. It’s the perfect drone for maritime uses.
