Ship Galley and Accommodation Electrical Upgrades: Capacity and Interfaces
Updated
New galley or accommodation equipment can change a vessel's electrical demand, distribution and maintenance requirements. The order should cover load assessment and installation interfaces as well as the appliance. Identify simultaneous operation, ventilation, local isolation and environmental conditions before assuming that an existing socket or breaker can support the change.

Key takeaways
- Appliance and operating-load schedule
- Supply and protection review
- Ventilation and other trade interfaces
- Revised circuit and acceptance records
Build a realistic equipment schedule
List equipment ratings, operating patterns and supply requirements alongside the proposed locations. Distinguish connected load from expected simultaneous demand without inventing a diversity allowance. The responsible engineer should assess the distribution arrangement and protection. Include start-up characteristics or power-electronic loads where they affect the evaluation.
Coordinate neighbouring systems
Galley equipment may depend on ventilation, water, drainage or interlocks. Allocate these interfaces to the appropriate trades and identify which conditions are needed for commissioning. Consider service access and exposure at the cable entry. Electrical completion alone cannot demonstrate that a new appliance is ready for its intended operation.
Control changes to accommodation circuits
Document revised distribution schedules and identify circuits affected by alterations. Temporary supply arrangements should remain separately controlled, not disappear into the permanent installation. The completion record should distinguish verified functions from checks awaiting another trade, particularly where refurbishment continues after the electrical team leaves.
Illustrative procurement scenario
A replacement cooking appliance has a different supply requirement from the removed unit. The survey identifies both a circuit modification and a ventilation interface. The owner obtains a coordinated work package instead of asking the electrician to improvise a connection during the final hours of the refit.
Sea Clean electrical work and personnel enquiries
Sea Clean supplies electricians for vessel installation, repair and project support, with electrical personnel hire and technical crewing enquiries also welcome. The proposal defines the work, competence, supervision and any required specialist or approved-provider involvement. Attendance, personnel availability and commercial terms are stated for the specific assignment.
For this enquiry, include: Existing and proposed equipment data, locations, supply drawings, simultaneous use, refurbishment schedule and trade interfaces.

Frequently asked questions
Does equal appliance power mean a like-for-like replacement?
Not necessarily. Supply arrangement, starting behaviour, controls, environmental suitability and interfaces can differ even at the same stated power.
