NEWS FROM OCEAN GROUPDecember was very busy at Ocean Group, with the resumption of port towage operations in Port-Car-tier and the towing operation of the Cecon Excellence.

Resumption of port towage operations in Port-Cartier

Océan Remorquage Côte-Nord (ORCN) consolidates its presence in the Northeastern Quebec region with the resumption of port towage operations in Port-Cartier.

ORCN tugs positioned in Sept-Îles will support the tugs Vachon and Brochu belonging to the mining company ArcelorMittal for docking and undocking maneuvers of bulk carriers at the terminal. They will also operate the shuttle service for ore ships at anchor.

A complex maritime operation on the St. Lawrence

Over the past few days, the teams of Ocean Naval and Industrial Repairs (NIR) worked hard to finalize the last preparations for the transfer of the Cecon Excellence hull on the impressive semi-submersible vessel Transshelf.

Four tugs from Océan Remorquage Québec were able to successfully complete the movement of the hull aboard the Transshelf submerged at anchorage D, near the Île d’Orléans, in the waters of the Port of Québec.

The Cecon Excellence is now on board the ship and NIR employees are securing it aboard the Trans-shelf before its departure to a shipyard overseas.

A few days from the beginning of the Holiday Season, the Roue libre-Port de Trois-Rivières team is making a generous donation to the students of Saint-Do-minique-et-Sainte-Catherine-de-Sienne School of $25,650, which it raised by participating in the Grand défi Pierre Lavoie (GDPL).

The school’s staff, who promote a healthy lifestyle, offer an outdoor compo-nent to their educa-tional project. With the money they are receiving today, the school will improve sports-related ou-tings for students, acquire equipment for working on child-ren’s psychomotility, purchase new physi-cal education mate-rial, and paint game lines for an active schoolyard.

For Gaétan Boivin, President and CEO of the Port of Trois-Rivières, «All efforts made by team members, such as training and raising money, are a true inspi-ration. This example encourages students to dare to realize their own dreams. The new sports equipment

will help them gradually develop the perseverance necessary to reach them.» This year’s sponsorship has held a special meaning for the Port of Trois-Rivières, as one of the school’s two buildings is located in a neighbourhood along the St. Lawrence River. There-fore, it is children living in a neighbourhood near the Port who will benefit from the money raised, and this is important to the organi-zation.Source : Port de Trois-Rivières

After last month’s discussion on the effects of potential regulations go-verning underwater noise emitted by ships, today’s article addresses measures to be implemented to reduce the sound impacts of ship-ping activities.

Noise reduction methods

In 2014, the IMO published a do-cument on voluntary ship’s noise

reduction measures. Some of the measures it contains are relatively simple and inexpensive and are already being applied by certain enthusiasts. However, the docu-ment also points out that it is diffi-cult to integrate far-reaching noise reduction measures into the exis-ting fleet. Acoustics criteria must be kept in mind at the ship design stage.

A recent article cites Kathy Metcalf, President and CEO of the Chamber of Shipping of America, who states that including quieter propulsion systems could repre-sent as little as 1% of a ship’s pur-chase price. This low-cost solution is based on the assumption of a larger-diameter, reduced-speed propeller, generally characterized by less cavitation and better per-

formance.

Both of these publications raise an important point, namely that the new ship design stage is the most effective moment to intervene in a ship’s life cycle to reduce acoustic impact.

However, not all is lost for existing vessels. In many cases, speed reduction remains an effective means of diminishing the noise a ship emits. Ac-cording to the IMO, cavitation is the main source of noise and occurs as of a certain propeller ro-tation speed, in keeping with propeller condition and characteristics (pitch, diameter, number of blades, area ratios, tip bevel). The key is to get as close as possible to the rotation speed that en-ables a reduction in the biggest noise source.

Another interesting point for existing ships is to ensure that the vessel’s mechanical equipment is in good condition so as not to transmit vibrations to the structure, thereby limiting another source of noise.

Beneficial effects for crews

A positive, indirect effect of noise reduction mea-sures on external surroundings is that the crew’s working environment is also improved. Remem-ber that, for crew members, the ship is not only a workplace but also a living environment. This is why it is especially important to ensure that ships’ employees have properly sound-proofed rest areas. It has been shown that employees with ac-cess to calmer rest areas were better rested and, hence, less tired. Since fatigue is a key factor in human error and since mistakes can be costly on many fronts, it is desirable to do our utmost to avoid them.

Conclusion

These past two months, we have discussed a nu-mber of issues related to acoustics in the marine environment. The subject raises many questions and will, very likely, become even more important in the near future. The key players must remain proactive and continue to work together to imple-

ment best practices in order to pursue their eco-nomic activities without adversely impacting the environment.

In fall 2015, Claude Jean published the third edition of “Mécanique des moteurs diesel marins”, a textbook on the mechanics of marine diesel engines intended for students of the IMQ’s Marine Mechanical Engineering Technology program. This new edition complies with Transport Canada, Marine Safety’s Marine Technical Review Board (MTRB) requirements in keeping with the Canada Shipping Act (CSA, 2001) and the Administra-tive Monetary Penalties Regulations in force since April 2008. It covers: two-stroke and four-stroke engine operating cycles - description of slow and fast engines - valve control mechanisms and their construction - lu-bricants, cooling of engine structures, auxiliary circuits and apparatus - start-up and reversing devices.

Jean Cloutier and Jean-Pierre Charest recently published “Les ba-teaux-phares du Saint-Laurent”, a book on the evolution of those ships «that weren’t going anywhere». The volume reveals a fascinating human aspect, among others through interesting interviews with the last survi-vors who lived on these “lightships”. It offers detailed visits of the mooring facilities and the assigned ships that dotted the majestic St. Lawrence from Traverse-en-Haut to the eastern point of Anticosti Island. Rich in ico-nography, the volume is a tribute to these forgotten actors.

In fall 2016, Marie-Andrée Mongeau released her second novel, “Le Ma-gicien de la mer ne fait pas de miracle!”, whose story unfolds aboard a supertanker in the Persian Gulf in the early 1990s. “Sometimes, it is good to recall our shipboard memories. Oh, those sweet sailing days! We look back with nostalgia, longing. For those who have forgotten how beautiful the sea is…the attraction of the unknown (especially the bright-eyed, cur-ly-haired blond sailor)…as the snow falls, I offer recollections of my jour-ney on the Sea Wizard, which, between you and me, should more aptly be named the Sea Hazard, or «danger of the sea».” [Translation]

Congratulations to the authors and happy reading to one and all!
