The condition-based monitoring software will be implemented across Seaspan's entire fleet of 76 vessels over the next several years.
"We developed our own temporary Hull Structure monitoring system at Seaspan in order to help us understand our needs and to quickly help us manage hull defects until we could assess and decided on our preferred system," explained Peter Jackson, director of the Projects and Technology Department at Seaspan Ship Management Ltd.
"Three different systems were reviewed and as a result, GL HullManager was selected as the software most closely meeting our needs."
GL HullManager is a part of GL's fleet management software portfolio, providing hull inspection and thickness measurement support. Inspection, reporting and condition assessments of tanks, cargo holds and coatings are supported, throughout the vessel's lifecycle, by means of crew inspections and thickness measurements.
A vessel-specific 3D model allows for visualisation and assessment of the hull's structural condition, where the crew can mark any coating or structural failures on the 3D model, such as marking an individual finding or adding a photo and descriptions, which can then be assessed by superintendents onshore.
Ryan Bishop, GL's vice president business development for the Americas, noted: "Clients are finding that the system is one that they can easily integrate into their existing maintenance processes, with the added benefit of on- and offshore teams having access to the same data."
"With the training we can provide from local offices, we are confident that this partnership with Seaspan will see them roll out GL HullManager without a hitch."
GL HullManager can make information on the condition of hull structures available to any employee across the company once the inspection results have been approved and synchronised.
Stored in a lifecycle database, hull condition data for each individual vessel can be traced over time and sister vessels from the same fleet can be compared. A dashboard overview of the ship makes it easy to pinpoint any critical findings by crew or third-party inspectors.
Introduced in 2011, GL HullManager is used on 350 vessels of all kinds worldwide, and has recently been upgraded with a mobile client version for use in compartments.
Upcoming additional features in development include an automatic proposal for the amount of steel to be replaced for a dry dock tender specification, integration of hatch cover tightness measurement results and hot spot marking functionality.
