Management of Environmental issues like Noise , GHG  Emissions as well as Ballast Water Transport  impact on Marine Life continue to have an ever increasing impact on the delivery of Marine projects

Noise Pollution and Marine Life

IMO guidelines provide practical measures to reduce shipping noise, Highlighting cavitation, aeration near the propeller blades as the biggest source of noise. Slow Steaming as well as propeller maintenance and wake flow design (to make the water flow without turbulence) around the stern of the hull help to reduce this source of noise. As this is easier to design into new builds the guidelines can be incorporated easily into new ships but masking the wide range of machinary noise on existing vessels is as important and worthy of attention.

The  75000 or more hulls in commercial shipping today must all review Vassili Papastavrou recommendations  as a whale researcher who invaluable  experience in this area.

Emissions Management

The Ship Energy Efficiency Management Plan (SEEMP) is an operational measure that establishes a mechanism to improve the energy efficiency of a ship in a cost-effective manner.

The MRV shipping Regulation adopted in April 2015 creates an EU-wide legal framework for the monitoring, reporting and verification of CO2 emissions .

By 30 August 2017 submit to an accredited MRV shipping verifier aMonitoring Plan, consisting of complete and transparent documentation of the monitoring method and procedures to be applied for each of the ships under its responsibilities

Ballast Water Management

The BWM Convention will enter into force on 8 September 2017.
The adoption of all the required Guidelines for the uniform implementation of the BWM Convention and the approval and certification of modern ballast water treatment technologies have removed the major barriers to the ratification of the instrument and a number of additional countries have indicated their intention to accede to this Convention in the near future.
