Rivertrace and Prevention at Sea partner on integrated Smartsafe ε-ORB discharge monitoring system

Water quality monitoring specialist Rivertrace Limited has integrated the ε-ORB software application developed by marine risk prevention specialist Prevention at Sea Ltd into its Smartsafe ORB bilge overboard security system monitoring equipment.

The two systems have been brought together through an API created by digital technology provider Intellore, allowing data collected by Rivertrace’s Smartsafe ORB to be automatically entered into a certified electronic oil record book (ORB), the Ɛ-ORB, removing the need for manual entries.

Prevention at Sea’s ε-ORB system was the first electronic ORB to be approved by a major flag state (Liberian Registry). Since then it has achieved certification from three IACS members and approvals from most major flag states.

Rivertrace originally developed Smartsafe ORB as a complete interlocked system that enables the electronic recording of discharges, to prevent the use of “magic pPipes”, illegal discharges and to minimize discrepancies in a ship’s oil record book. In its simplest form, Smartsafe Ɛ-ORB utilizes GPS and records each “event” of the bilge water discharge process.

Recent updates to Smartsafe ORB have made the system smaller and lighter with installation requirements simplified. The system now features a camera that is integrated into the separator interface to capture tampering for increased security.

The integration of Prevention at Sea’s ε-ORB software application will now allow users to replace traditional paper oil record books (ORB) (Part I and Part II) and facilitate accurate ORB entries into an efficient electronic format. This prevents the input of vague entries, incorrect ORB format and code mismatches and supports automatic and secured transmission of records between the fleet and operator offices by using the existing communication systems on board.

Together the combined Smartsafe ε-ORB promotes transparency, credibility, and traceability in accordance with the MARPOL, IMO Circ. 736/Circ. 2 and MEPC 312(74) requirements.

Martin Saunders, Operations Director at Rivertrace says: “We believe that the collaboration between Rivertrace and Prevention at Sea will be very beneficial for the customer bases of both companies. Digital technology is changing the landscape of our industry and through this strategic technology integration, we are supporting our customers in their quest for simplified, continuous monitoring and efficient operations.”
