Design of extensive Electrical System with Power Generation and Power distribution analysis according to vessel configuration, safety and reliability. This involves the Selection of the appropriate large drivers, picking the correct generation configuration (including prime, essential and emergency sources), configuring the electrical distribution system and deciding the various details of the electrical distribution, control and safety system.
The complete load analysis of electrical loads considering various load cases. Sizing of Prime source like Generators, Essential loads and Emergency source of power (Emergency Diesel Generator), Sizing of Medium voltage and low voltage power distribution transformers.
Preparation of Single Line Diagram for complete Power distribution system, Switchgear sizing, Cable sizing, Battery sizing as per IEC standards, API regulations and class rules. Establishing the philosophy for protection, co-ordination and safety of the power generation and distribution system.
Complete Switchboard room layout and arrangement considering the power distribution, different voltage levels, operational flexibility and ergonomics. Battery and UPS room layout design. Layout Engineering of Electrical equipments considering the power distribution system, operational requirements, hazardous area applications, safety etc.
Sizing of uninterruptible power supply (UPS) for critical services and Safety systems. Direct current supplies for specialized equipments. Design of automation systems covering process control and safety systems, including emergency shutdown (ESD) and fire and gas (F&G) detection and control.
Deciding and categorizing of the hazardous zoning and preparation of hazardous area plan for selection of correct type of equipment's/instruments to suit the zone requirements. Selection of correct Ex. rating and temperature class of the equipment's to be installed in hazardous environment.
Design and engineering of auxiliaries like cable tray routing for Topside, hull and living quarters. Earthing system design and layout, MCT block design and arrangements, Normal, Emergency and Critical Lighting System and layout.
Procurement engineering including preparation of RFQ, Vendor offer evaluation as per tender requirements and regulatory authorities requirements, Technical liaising/negotiations with vendors for optimized solutions, Preparation of technical evaluation documents and purchase specifications.
In case of conversion, Pre-engineering survey can be carried out for all the equipments on board the vessel. This engineering activity is very critical in order to assess the condition of equipments which can be retained and identify the equipments to be replaced. Also identification of modifications required to be done on the existing system to suit the requirements of conversion.
