ABS guildline for portable offshore accommodation modules

The installation of modular buildings for use as living quarters, industrial spaces, and workshops has become increasingly prevalent in recent years. Irrespective of the amount of time that portable modules are installed onboard, the potential risks to personnel within these buildings can be comparable to those within a traditional living quarters structure.
Due to the transient nature of portable accommodation modules, it is possible that the buildings may be installed on a number of different types of vessels and offshore units over their life. In recognizing that the ABS class requirements differ based on the type of host vessel or facility, this Guide has been created to outline the process for the design and survey of the modules and to establish the requirements for modules which can be used on any category of offshore drilling unit, production facility, barge, steel vessel, or high speed craft.

Class Approval Process
The ABS approval process for accommodation modules is a four-step process as outlined below:
• Design Review of the Module 
• Survey of the Module at Fabrication Facility
• Design Review for Installation Approval 
• Survey onboard Host Vessel 

The ABS review process of the module commences with drawings and documentation detailing the module’s general arrangements, structural fire protection, electrical configuration, structural design, and machinery and piping systems being submitted to the ABS technical office for review. Upon completion of the review, drawings will be returned to the submitter and forwarded to the attending ABS Surveyor. Receipt of the drawings by the ABS Surveyor permits the physical survey of the module at the fabrication facility to be commenced.
Once a host vessel for the module is determined, design review for installation approval can be commenced. Upon receipt of the documentation detailing the module and the proposed location onboard the host vessel, the ABS technical office can review the arrangements. Once the ABS engineers have determined that the proposed location onboard the host vessel is suitable for the subject module, stamped drawings will be returned to the submitter and made available to the attending ABS Survey office. Upon receipt of these drawings, the attending ABS Surveyor may attend the vessel and confirm that the installation of the modules is in accordance with the approved arrangements.
The manufacturer is to assign a unique serial number to identify all modules being reviewed to this Guide. The initial submission of drawings is to specifically indicate the serial number of modules to be built in accordance with the drawings.

Lithium battery fires are mainly the result of the decomposition and burning of electrolyte, which is a kind of hydrocarbon gas burning fire. In the case of battery overheating, excessive charging and discharging, battery design defects and short circuits caused by raw material defects, chemical reactions occur between battery materials inside the battery, and the electrolyte decomposes to generate a large amount of heat and gas, resulting in thermal runaway of the battery. The thermal runaway is the main reason for the burning of the electrolyte. Once thermal runaway occurs, the battery temperature rises rapidly, directly causing the battery material to burn. When the concentration of flammable gas produced by the decomposition and combustion of the lithium battery electrolyte reaches a certain level, it will explode when it encounters an open flame. In large-scale battery energy storage containers, the battery packs have the characteristics of high density and centralized distribution. The lithium battery modules are connected in series to form a single battery pack and multiple battery packs. A large-capacity energy storage unit is formed in parallel, which not only increases the probability of lithium battery failure, but also increases the fire spread channel because the battery cannot be cut off in the event of a fire.
There are a large number of auxiliary electrical equipment in the lithium battery energy storage container. The unsafe use of these equipment also increases the overall fire risk of the storage container, such as accidental high voltage and large current (lighting, surge) intrusion. High voltage and high current invade the lithium battery energy storage container. On the one hand, the electronic equipment in the lithium battery energy storage container is highly integrated, which reduces its resistance to high voltage and high current; on the other hand, the system uses a large number of communication lines have added channels for high voltage and high current intrusion. At the same time, the failure of the protection element is also one of the important causes of fire. Long-term heating and ultra-high temperature caused oxidation and corrosion of some electrical components in the cabinet, and aging of some insulating materials. The overcurrent protection in the battery, the DC fuse and the overcurrent fuse in the battery failed to effectively isolate the short circuit fault and could not meet the original design resistance and insulation. Therefore, the overall electrical safety of the lithium battery energy storage container system has a large hidden danger, and it will cause the spread of fire.
When a lithium battery burns, a large amount of gas is generated, mainly organic gases such as hydrogen, carbon monohydride, carbon dihydride, methane, benzene, and toxic gases such as hydrogen chloride and hydrogen fluoride.
In the event of a fire, the hydrogen, carbon monohydride and other combustible gases released by the lithium battery inside the lithium battery energy storage container under high temperature conditions cannot be effectively controlled, which may cause the fire to spread rapidly or even explode, endangering the main electrical equipment, and causing property damage.
The fire extinguishing system in Lithium battery energy storage container adopts non-conductive suspension type, cabinet type or pipe network type heptafluoropropane (HFC) fire extinguishing system. At the same time, a nitrogen fire extinguishing system is also arranged. The lithium battery energy storage container gas fire extinguishing system consists of heptafluoropropane (HFC) fire extinguishing device, pressure relief device, gas fire extinguishing controller, fire detector and controller, emergency start stop button and isolation module, smoke detector, sound and light alarm, etc. to realize automatic detection, alarm, and fire protection functions in the protection zone.
In the containerized lithium battery energy storage system, each container is a protection area, when smoke or temperature change is detected, the sound and light alarm will immediately respond to the fire. Extinguishing the fire in the early stage ensures the safety of the energy storage container. At the same time, considering the processing method of the collected signals, to increase the number of audible and visual alarms and arrange them in places where there are frequent patrols and guards.
At the same time, considering that lithium battery energy storage containers are prone to explosion, according to the characteristics of different lithium batteries, the corresponding explosion-proof system is configured according to the characteristics of different lithium batteries. The fire extinguishing system is also inter-connected with the controller, the fan, power supply, etc. and transmit the fire signal to the fire control centers.

All solar panels can be folderable and put into the standard ISO dimension container, which is very conveninent for transporation and quick for unfold at the site. All other accessories including battery, inverter, etc are also installed inside the container. 
if you have any inquiries on the solar panel containers, please don't hesitate to contact us.
