Norwegian ship classification organisation DNV GL has secured a contract to install its hull maintenance system on Saipem’s vessels.

Known as ShipManager Hull, the system will be installed on five of the Saipem ships.

The installation will start with Saipem 7000, a crane vessel that has a lifting capability of around 14,000t.

ShipManager Hull will also be implemented on crane vessel FDS2 (2011), as well as pipelaying vessels FDS (2000), Castorone (2012) and Constellation (2014).

Crane ships require special attention to structural integrity as they face high stresses during lifting. Due to repeated ballasting, it becomes vital for ship-owners to ensure efficient monitoring of ballast tank corrosion.

Using 3D digital twins of the entire structure, Saipem will be able to plan optimised examinations and dry-dock repairs of the structure periodically.

Additionally, the software will enable the company to carry out complete lifecycle management of the hull structure.

Saipem Asset Digital Transformation leader Giampaolo Bonalumi said: “With this powerful tool we will be fully in control of the condition of the hull of our construction vessels.”

DNV GL EMEA Digital Solutions vice-president and regional manager Ketil Aamnes said: “ShipManager Hull is a proven tool in the maritime industry and is growing within the offshore industry.

“Saipem is demonstrating the value of the solution for specialised structures such as crane and pipelaying vessels.”

ShipManager Hull, which is part of DNV GL’s maritime software portfolio, is currently being used on more than 6500 vessels across the globe.

ShipManager includes modules for technical management, hull integrity management, procurement, QHSE, crewing and business intelligence.

Last month, DNV GL announced that it will offer an online Ship Implementation Plan (SIP) for shipowners and managers ahead of updated sulphur cap rules, wich come into force next year.
