Seakeeper

Autonomous Sea Surface and Atmospheric Monitor

The Seakeeper Sea Surface and Weather monitoring systems continually collects data on the ocean and atmosphere where ever the ship or platform my be. This data is stored along with the ships current position in an on board computer and may be transmitted back to shore using the an Inmarsat C Transceiver. The system has a modular design that allows for up to 5 sensor suites to accommodate used needs now and in the future. The system is designed to operate autonomously without the need for skilled technicians on either a Shipboard Installation or Shore Installation.

Features:

Modular Design.

Autonomous Operation

Separate Control and Sensor Modules.

Two way communication link.

Stainless Steel Construction.

Network Compatible

Expandable.

Description
The system consists of 3 major components. Computer Module (dry), housed is a separate stainless steel enclosure, which contains system power supplies, computer and control software and the Inmarsat C transceiver. Instrument Module (wet) with room for five sensor suites, water pump, leak moisture detector and water flow (controllable) manifold. Water Intake and Plumbing System includes external water through hull intake pod with thermometer, water intake and exhaust valves (Lloyds Certified) for emergency shut-off, stainless steel jacketed Teflon lined tubing and containment vessel with automatic shut-off for internal leak protection. The system automatically collects data from a on board marine Weather Station along with ship location and transmits data back to shore via an Inmarsat C transceiver Satellite GPS.
