This Load Moment Control system, equipped with 10 pairs of tanks and 15 anti-heeling pumps, enables fast and automated heavy-lift operations in heavy-list mode, which also makes the Aegir one of the most powerful vessels of its kind due to its crane capacity.
Previously focused also on pipeline projects, the Aegir has been further optimized for its current task area of fast offshore transports and installations.
For this purpose, among other things, the lifting capacity was increased to 5,000 metric tons with a delivery of 17 m to 40 m.
In line with the increased performance, the Load Moment Control System has also been updated, which includes an update of the software as well as additional functions such as Automatic Tank Level Synchronization and a zero-flow mode, which further increases the reaction speed of the system.
How does LMC work?
LMC simulates the impact of the crane slewing process under a given load on the vessel’s floating condition (trim, heeling) on-line during the operation and calculates the appropriate ballast operations to keep the vessel in the defined floating condition within a narrow window of tolerance. Combined with Hoppe Marine’s unique variable frequency drive pump Heel Control, LMC enables step less and rapid automatic anti-heeling compensation, even for complex and large scale ballast systems. Hoppe Marine LMC uses load simulation combined with real time motion reference data, enabling heavy lift anti-heeling operations also at sea.
