DNV, the world’s leading classification society, and Navis, the leading provider of port and terminal operating systems and carrier and vessel solutions, today announced a new joint solution to minimise the risk of container incidents at sea by combining DNV Anti-Roll Assist and Navis Lashing Monitor.

“Container losses are rare, but the impact of those losses can be very significant, both in financial and reputational terms,” said DNV Maritime senior principal engineer and programme development manager for containerships Arne Schulz-Heimbeck. “DNV Anti-Roll Assist, deployed together with Navis Lashing Monitor, gives captains and crews a clear and simple picture of the risk of container loss based on their heading and speed, and supports them in assessing if they need to make navigational adjustments. We are very pleased to work with Navis to give ship operators and vessel crews this powerful toolset that helps avoid potentially critical situations.”

With careful maintenance and high-quality lashing systems and equipment, containerships can operate safely, even in harsh conditions. However, certain conditions may lead to synchronous and parametric rolling, which can be very challenging to predict and increases the risk of container loss. By integrating the Anti-Roll Assist seakeeping calculations into the Navis Lashing Monitor tool, which monitors real-time vessel motion data and lashing forces, ship operators and vessel crews can view design values alongside actual cargo and cargo securing data.

“Crews are balancing maximum loading capacity, time pressure, and profitability while having to deliver optimum vessel-safe seakeeping behavior in ever-changing weather situations,” said Navis product vice-president Carlos Barbera. “Providing additional essential information and operational guidance to ship operators and vessel crews so they can make informed decisions and prioritise safety at sea is a responsibility we take very seriously and are privileged to partner with DNV to deliver it.”

DNV’s anti-roll software and services are supported by a new DNV class notation called ARCS, Anti-Roll for Containerships, which enables shipowners to demonstrate their container loss minimisation strategy to their customers. Owners can satisfy the requirement of the ARCS class notation by implementing a software solution, such as Navis’ Lashing Monitor, which meets the functional, technical and performance requirements, with a particularly stringent hydrodynamic approach to calculating the risk.
