Seaspan Ship Management has actually picked Alfa Laval to aid settle heavy steam equilibrium and also redundancy concerns attached to sulphur-compliant gas. The detailed remedy– an incorporated heavy steam central heating boiler plant making up oil-fired heavy steam manufacturing, waste warm recuperation, progressed control and also connection– will certainly quickly be executed on 8 Seaspan had huge container ships.
Prior to the IMO worldwide sulphur cap’s entrance right into pressure, Seaspan Ship Management decided to collaborate with sulphur-compliant gas on its container vessels. Like most container vessels, nevertheless, the Seaspan had vessels have just a solitary oil-fired central heating boiler and also a waste warm recuperation central heating boiler aboard. This gives no redundancy, which is troublesome when making use of sulphur-compliant gas.
“The composition of low-sulphur fuels was uncertain when we first decided for them, but it quickly became clear that high paraffin content would be an issue,” claims Arvin Dsouza, Fleet Manager atSeaspan Ship Management “To avoid wax formation, the fuel temperature has to stay above the pour point at all times. But the existing boiler solution on the above-mentioned vessels can’t guarantee the required steam capacity as these vessels do not have heating coils in all the designated fuel oil tanks and rely on a shifter system. We chose to work with Alfa Laval, who found the answers we needed.”

Three central heating boilers working as one reliable system
To safeguard an adequate and also dependable supply of heavy steam, consisting of full speed plant redundancy, Alfa Laval recommended reconstructing the existing oil-fired central heating boiler and also including a brand-new Alfa Laval Aalborg oil-fired central heating boiler. This will certainly sustain gas home heating through heavy steam coils in all containers. Both the terminated central heating boilers and also the waste warm recuperation central heating boiler will certainly be adjoined with the Alfa Laval Touch Control system, producing a solitary heavy steam remedy.
“Alfa Laval is unique in having all the boiler, burner and control technologies in-house,” claimsDsouza “They presented a complete heating solution that keeps as much as possible of the existing equipment on board, but which integrates the different components for smooth performance as one system. With their knowledge, they could tie everything together.”
Seamless assimilation and also adaptable control
On each container vessel, Alfa Laval professionals will certainly remove out and also change the electric parts of initial oil-fired central heating boiler, which was provided by a various maker. However, they will certainly absorb its stress area, ring line devices and also heater, utilizing them to develop a brand-new central heating boiler with the ability of being attached to the Alfa Laval Touch Control system. For a smooth remedy, the very same sort of heater will certainly be made use of on the brand-new Aalborg central heating boiler.
“Rather than replacing the competitor burner with their own, Alfa Laval is incorporating the same type, so that we can make use of the knowledge and parts we have on board,” claimsDsouza “Everything, including waste heat recovery, will be smoothly handled through the Alfa Laval Touch Control system, as if it had all come from Alfa Laval in the first place.”
The Alfa Laval Touch Control system, which will certainly change the older central heating boiler’s relay-based control system, is a PLC-based system that can run the oil-fired central heating boilers in either master/slave or load-sharing settings. “We’ll have complete operational flexibility,” claims Dsouza, that commends the system’s simplicity of usage. “Through the graphical touchscreen, the operators will have a full overview of the steam plant and be able to make adjustments with just a touch or two.”
Connected for more powerful assistance
Beyond the opportunities provided by the control system, the brand-new central heating boiler remedy will certainly be outfitted for connection. Alfa Laval solution professionals will certainly have the ability to check the system’s problem from another location, producing chances for repairing, support and also optimization. Based on gathered information, for instance, they will certainly have the ability to lead the team in carrying out essential upkeep treatments or timetable area solutions like burning adjusting when called for.
“Connectivity will give us deeper and more continuous contact with Alfa Laval service expertise,” claimsDsouza “It will mean peace of mind, but also more effective and cost-efficient use of our boiler systems over time.”
Installations ashore or mixed-up
Satisfied with the brand-new heavy steam plant remedy, Seaspan Ship Management will certainly carry out the arrangement on the initial container vessel in very early springtime of 2020. Installations will certainly after that continue the continuing to be 7 vessels, running throughout 2020 and also right into 2021. The installments are intended to happen in a shipyard, yet they can be carried out mixed-up if unanticipated disturbances in backyard routines make it essential.
“We will be able to move forward with the projects, even if circumstances mean we can’t install at the yard,” claimsDsouza “Alfa Laval has the capability to deliver the parts and install them while the vessel is underway. Whether the installations happen in dry dock or at sea, we’re confident in the solution and we know we count on Alfa Laval’s quality and efficiency.”
