July 2020 – PMSC S.A. can perform Dynamic Simulations and analysis of Mooring Systems

It’s becoming greater and greater into the Shipping World the sensitivity to safety and reliability of ship’s mooring.

Some years ago the only two International Organisations dealing with mooring system performance, safety and effectiveness were OCIMF & SIGTTO. Nowadays also Classification Societies, Port Authorities and some Local Legislation are facing the necessity to evaluate and guarantee, under given or specific environmental condition, the mooring capability of the vessels.

PMSC S.A. knowledge, experience, capability and computational facilities can help Ship-Owners and Ship Operators in evaluating and improving, as and if necessary, the effectiveness of their Ship’s mooring systems.

PMSC S.A. can perform mooring analysis and evaluations both in static and dynamic conditions. Ranging from traditional mooring to Single Buoy Mooring and to Ship to Ship transfer mooring operations.

For Ports, Harbour and Terminal we can also perform passing ship analysis on moored vessels.

All the computations are performed according to International Standards and Requirements with the use of Optimoor® software in its most updated Dynamic version.

September 2019 – 5th LNG & Clean Marine Fuel Forum – Singapore

On September 2019 in Singapore was officially presented the Heat Recovery System designed by PMSC S.A. and engineered by Viking Airtech Ltd.

The occasion was the 5th LNG & Clean Marine Fuel Forum – Fuel for Cleaner Shipping held in Singapore.

Abstract of the presentation:

The use of LNG as bunker on board commercial vessel is increasing, both considering the number of ship converted or built “on purpose” and the number of ships ordered as “LNG Ready”.

One of the main characteristic of LNG is the cryogenic temperature at liquid phase, that even if the storage pressure rises, it’s always very low.

Both Dual Fuel Engines and Pure Gas Engines need to be fed with vaporized Natural Gas at a given temperature (normally well above 20°C).

This means that the LNG stored on board in the liquid phase, must be vaporized and heated up. To vaporize LNG to the required characteristics, a certain quantity of heating energy is needed.

On board commercial vessel there are plants that require cooling media to cool them down during operation and having on board abundant cold energy liquid that need to be vaporized and heated up drives the idea to use the heating needs of LNG to cool down those plants that require controlled cold energy to work properly.

The paper will describe an cold energy recovery system that vaporizes and heats up the LNG for feeding the engine, and utilizes the cooled down heat exchange media as cooling agent for air conditioning & refrigerating Plants.

The proposed LNG Energy Recovery System has been approved in principle by DNV-GL for use on board vessel according to IMO – IGC & IGF Codes.
