For this reason, ship motion and RPM monitoring software will be more widely used in this sector.
“Often, wave height restricted designs are the only solution to transport such cargo, and with the aid of products such as Amarcon’s OCTOPUS-Onboard, more weight and size critical sea transports become feasible. They offer control measures to facilitate such wave restricted sea transports that could not be conducted in unrestricted environmental conditions,” says Bauer.
Three years ago, SAL Heavy Lift stepped into the offshore market with the acquisition of MV Lone, which it then fitted with OCTOPUS-Onboard. The vessel is equipped with a modern dynamic positioning system dedicated for offshore installation projects.
A clear picture of the ship’s seakeeping behavior is even more critical for successful offshore installations, where sea and wind conditions need to be much milder than for standard sea transportations.
“With a growing offshore market, other ships in our fleet are likely to be equipped with OCTOPUS-Onboard,” says Bauer. He adds that the company appreciates the “holistic approach of using OCTOPUS-Office in combination with OCTOPUS-Onboard, which is deemed a rational strategy for the heavy lift sector.”
Plans to train entire fleet
In brief, SAL Heavy Lift use OCTOPUS-Office for the onshore planning and design of MV Lone’s heavy cargo transport and OCTOPUS-Onboard to assist the shipmaster to safely transport cargo by monitoring the ship’s responses and RPM.
“So far, we have trained the shipmasters on MV Lone to use OCTOPUS-Onboard. Our hydrodynamic experts in the engineering department design and plan weather restricted sea transports with OCTOPUS-Office.”
With more weather restricted sea transports in the pipeline for the company, there are plans to train the shipmasters of SAL Heavy Lift’s entire fleet to use OCTOPUS-Onboard.
“We bought the system to help our shipmasters trace optimum routes on the basis of monitored seaway-induced accelerations and ship motions in adverse seas. We need accurate information about this dynamic ship behavior to secure large-sized and heavy cargo safely on all ocean routes during all seasons,” says Bauer.
He adds that the company also appreciates the system’s fuel-saving functionality in the far more often encountered milder seaways. The system is also used to perform route planning by accounting for forecasted seaway conditions provided by MeteoGroup’s shipboard weather forecast system SPOS.
“There are very few, if any, systems on the market that offer the variety of functionalities that OCTOPUS-Office and OCTOPUS-Onboard do. Because OCTOPUS-Onboard was one of the first shipboard decision-making support systems, its long experience was a strong argument for choosing it.
We wanted a system that matched our requirements. Robustness is also important to avoid costly downtime of the system. When this does happen, we need prompt high quality support at short notice, as well as smooth maintenance and regular upgrades,” concludes Bauer.
