Marine Engineer

Manage vessel machinery, bunker calculations, tanks, technical records and ORB Part I workflows in one professional, offline-ready workspace.

Marine Engineer is a vessel management and engineering workspace built for marine engineers and engine officers.

Keep machinery details, calculations, tank measurements, daily work, technical notes and documents organised by vessel, even while working offline at sea.

KEY FEATURES

Vessel Profiles Create separate vessel profiles and keep technical information and operational records organised in one place.

Machinery Inventory Record main engines, diesel generators, boilers, pumps, separators, compressors, fresh water generators, refrigeration systems and auxiliary equipment.

Engineering Calculators Access practical tools for tank geometry, shaft power, engine performance, mechanical calculations, fluid systems, thermal calculations and unit conversions.

Bunker Fuel Calculator Calculate bunker quantities using tank measurements, temperature and density corrections. Prepare fuel blending and internal transfer calculations, and save records under the relevant vessel.

Tank Management Create calibrated tank profiles and calculate quantities from sounding or ullage measurements. Manage IOPP tank details and track balances associated with supported ORB operations.

Logbook and Technical Notes Record daily activities, maintenance work, outstanding tasks and watchkeeping notes. Track completed work and keep useful information ready for your next handover.

Edit and Delete Records Long-press supported saved records to edit or delete them. Update calculation inputs and recalculate results without creating duplicate records.

Handover PDF Reports Export structured reports to help organise vessel information and recorded work for professional handovers.

Vessel Document Archive Keep manuals, certificates, vessel photographs and technical files under the relevant vessel profile.

Certificate Tracking Record certificate issue and expiry dates, review renewal status and enable expiry reminders.

OPTIONAL ORB PART I MODULE

Prepare structured Oil Record Book Part I entries using operation-specific workflows for:

• Sludge collection, transfer and disposal
• Bilge water transfers and discharge
• 15 ppm equipment operations
• Bunkering
• Incineration
• Weekly inventory and equipment tests
• Additional ORB remarks

Use registered tank details, review calculated quantities for supported operations and check the structured preview before transferring information to the official Oil Record Book.

FREE ACCESS AND OPTIONAL PURCHASES

Manage one vessel free of charge.

EngineRoom Pro auto-renewing subscriptions provide additional vessel capacity. Available plans support up to 3, 5, 10 or 15 vessels, or unlimited vessels.

Knowledge. Safety. Efficiency. By your side, every watch.
