HYDRUS believing in the energy saving that can be achieved on board by good practices and energy management, can undertake to carry out Ship Energy Audit on board.

The scope of the Ship Energy Audit will be to determine the decomposition of the produced energy as well as to define the fields of improvement as far as the on board energy management is concerned. More specifically HYDRUS services are divided in three phases:


A. The pre-audit phase that is carried out onshore and includes:

  • Review of the Steam and Heat Balance Calculations as well as of the Electric Load Analysis
  • Review of the data from Shop Test & Sea Trial Results
  • Review of all major equipment operation manuals. Makers further assistance/clarification could be requested
  • Review of vessel's insulation scheme
  • Determine Ship's Energy Profile on a design basis

B. The on-board phase that includes:

  • Awareness meeting with Senior Crew Members
  • Assessment of M/E, A/E & Oil Fired Boiler Performance with respect to fuel oil consumption (as far as practicable).
  • Exhaust Gas Economizer Performance Assessment
  • Assessment of Auxiliary Loads Balance in comparison with the design 'Electric Load Analysis'
  • Assessment of Accommodation Energy Conservation (i.e. lighting and A/C unit Operation)
  • Assessment of Cargo Discharge Operations (if possible). Practices in conjunction with Cargo Pumps operation will be assessed. Cargo Pumps Makers' assistance will be required via above Phase A. (Applicable to Tanker Vessels)
  • Assessment of Autopilot Setting and capabilities
  • Assessment of the VOC release practices (Applicable to Tanker Vessels)
  • Assessment of the Cargo Heating and Bunker Heating practices. Measurements (if possible) will be made in order to enhance the Cargo Heating Monitoring Procedure (Applicable to Tanker Vessels)
  • Assessment of the E/R thermal insulation, compressed air system & steam piping system condition.
  • Carry out Speed Tests for assessing vessel's performance and comparison with the respective Sea Trials results. Pre-conditions are the suitable weather/sea conditions and capability of running in a range of speed values.

C. The after-audit phase that is carried out onshore and includes:

  • Evaluation of the data that have collected from the previous two phases that lead to the following deliverables:
  • Energy decomposition presentation based on actual operation profiles
  • Report of all above Items of No.B phase
  • Report on areas/practices that have a significant impact on energy performance
  • Identify immediate (especially no or low cost) improvements resulting into saving
  • Identification of feasible Energy Conservation Measures
